Bacteria of the genus Staphylococcus are gram-positive cocci that are microscopically observed as individual organisms, in pairs, and in irregular, grapelike clusters. The term Staphylococcus is.. Susceptibility to UTI depends on the status of the host defense mechanisms, the virulence of microorganism, and the inoculum size. The host defense mechanisms can be found in the vagina, urinary tract, and urine. Normally, the vagina and periurethral areas provide important defense mechanisms to prevent the progression of microorgansims from the rectum to the urethra. The acidity of vaginal secretions promotes the growth of normal flora such as lactobacillus and prevents the growth of uropathogens such as E coli. In the premenopausal woman, the vaginal pH is around 4. When the pH becomes less acidic, enterobacteria can colonize vaginal introitus and periurethral areas, thus predisposing to UTI.-Manifiesta una reacción negativas a las siguientes pruebas: coagulasa, descarboxilación de la ornitina, reducción de nitraros a nitritos y la fermentación de xilosa.Please note that Internet Explorer version 8.x is not supported as of January 1, 2016.

The population structure of E. coli is clonal, i.e. genetic elements occur in nonrandom, relatively stable combinations. Uropathogenic E. coli are a selected subset of the E. coli flora at large. The pyelonephritogenic clones are identified by a limited number of surface antigen serotypes (O:K:H:F = lipopolysaccharide (LPS), capsular polysaccharide, flagellar and fimbrial antigens) and intracellular isoenzyme patterns (electrophoretic types), and by the expression of molecules which damage the host tissues. Adherence is mediated by bacterial surface lectins, which may be associated with fimbriae. The lectins bind the bacteria to host receptor molecules consisting of oligosaccharide sequences in glycoproteins or glycolipids. The P fimbrial lectins recognize the Galα1–4Galβ and GalNAc epitopes within the globoseries of glycolipid receptors. S Fimbrial lectins recognize sialic acid residues, and type 1 fimbriae bind mannose residues found, for example, on the Tamm Horsfall protein and secretory immunoglobulin A (IgA), and connective tissue proteins such as collagen and laminin.Staphylococcus saprophyticus S. saprophyticus on Mueller-Hinton agar exhibiting resistance to novobiocin characteristic for species identification Scientific classification Domain: Bacteria Phylum: Firmicutes Class: Bacilli Order: Bacillales Family: Staphylococcaceae Genus: Staphylococcus Species:S. saprophyticus Binomial name Staphylococcus saprophyticus(Fairbrother 1940) Shaw et al. 1951Staphylococcus saprophyticus is a Gram-positive coccus belonging to the genus Staphylococcus .

Staphylococcus Saprophyticus - an overview ScienceDirect Topic

Staphylococcus aureus can be transmitted by contact from person to person. To prevent diseases you must follow the personal hygiene – wash hands frequently, don’t use other people’s towels and razors, to treat wounds and apply bandages on them, to avoid touching the skin lesions. In hospitals, the bacterium is frequently transmitted via the hands of medical staff. Special attention to the fight against staphylococci should be given in hospital as newborns are very vulnerable to infection. Pregnant women are usually screened for carriage of Staphylococcus before birth, so they didn’t infect their other children.The family Enterobacteriaceae is a large family of Gram-negative bacteria. It was first proposed by Rahn in 1936, and now includes over 50 genera and more than 200 species. Its classification above the level of family is still a subject of debate, but one classification places it in the order Enterobacteriales of the class Gammaproteobacteria in the phylum Proteobacteria.También se ha encontrado en casos de prostatitis, epididimitis, bacteriemia, sepsis, endocarditis y endoftalmitis

Staphylococcus saprophyticus - Microbiology - Medbullets Step

Two subspecies of S. saprophyticus exist: S. s. bovis and S. s. saprophyticus, the latter has colony diameter of > 5mm, and more commonly found in human UTIs. S. s. saprophyticus is nitrate-reductase negative and pyrrolidonyl-arylamidase negative, while S. saprophyticus bovis has colony diameter of < 5mm, nitrate-reductase positive and pyrolidonyl-arylamidase positive. [16] Patients with abnormal urinary tracts, e.g. renal stones, prostatic hypertrophy, indwelling urinary catheters, are likely to be infected with a more varied and antimicrobial-resistant microbial flora. Identification of the causative organism and of its sensitivity to drugs is important because of the range of organisms and the prevalence of resistant strains.Inflammation of the urinary bladder may occur acutely or extend to a chronic situation. Acute cystitis commonly occurs from urinary tract infections (UTIs) resulting from pathogens such as Escherichia coli, Staphylococcus saprophyticus, Proteus, Klebsiella, and Enterobacter. Urinary tract infections are also common causes of kidney infections (pyelonephritis). Prostatic enlargement, cystocele of the bladder, calculi (stones), or tumors can also result in cystitis.43,44

Gram stain or Gram staining, also called Gram's method, is a method of staining used to distinguish and classify bacterial species into two large groups. The name comes from the Danish bacteriologist Hans Christian Gram, who developed the technique.Urinary lactoferrin (LTF), a 80 kDa iron-binding protein secreted by polymorphonuclear white blood cells, is a predictive urinary tract infection (UTI) biomarker since the average concentration of LTF was found to be 30.4 ng mL−1 in health urine and 3300 ng mL−1 in infected urine. An electrochemical immunosensor has been designed for direct detection of the UTI biomarker lactoferrin from infected clinical samples (Pan et al., 2010). Alkanethiolate self-assembled monolayer (SAM) was used for an electrochemical biosensor array. Meanwhile, a sandwich amperometric immunoassay was established for detection of lactoferrin from urine, with a detection limit of 145 pg mL−1.For infection of the lower urinary tract a low dose may be effective, as many antimicrobials are concentrated in the urine. Infections of the substance of the kidney require the doses needed for any systemic infection. A large urine volume (over 1.5 L/day) and frequent micturition hasten elimination of infection.Для лечения стафилококковой инфекции применяются следующие группы препаратов:

  1. Community-aquired bacterial cystitis is commonly caused by E. coli (85%), followed by Proteus, Klebsiella, Enterococcus faecalis, and Staphylococcus saprophyticus. Nosocomial infections are usually due to E. coli (50%), Enterococcus, Klebsiella, Citrobacter, Serratia, Pseudomonas, and Providencia. Bacterial cystitis must be differentiated from hemorrhagic cystitis, which is an acute or insidious diffuse bleeding from the surface of the bladder. This condition, which produces significant bleeding requiring continuous bladder irrigation and fulguration, arises from bacterial, viral, fungal, or parasitic infections, drugs and other chemicals, such as cyclophosphamide, penicillins, industrial dyes, pesticides, and radiation.
  2. Acute pyelonephritis may be accompanied by septicaemia and is usually marked by fever and loin pain. In such patients it is advisable to start with co-amoxiclav i.v. or alternatively gentamicin (perhaps plus amoxicillin) i.v. If oral therapy is considered suitable, co-amoxiclav or ciprofloxacin is recommended for 2 weeks. This is an infection of the kidney substance and so needs adequate blood as well as urine concentrations, although a switch to an oral agent (guided by the results of susceptibility testing) to complete the course is recommended after the patient has clinically improved.

При сохранной иммунной системе сапрофитный стафилококк никак не проявляет себя и не приводит к развитию серьезной патологии.Speciation of CoNS is accomplished on the basis of a series of biochemical characteristics. In recent years, species identification has been simplified by the introduction of commercially available miniaturized kits.77 Differentiation of two strains belonging to the same species (subspeciation) represents a more difficult problem, however. Biotyping and antibiotic susceptibility patterns together have been used for this purpose with some success.105 Phage typing is another method that has been useful at times.105,106,107 Analogous to the situation with S. aureus, more powerful techniques for distinguishing strains of a given species include PFGE, random amplification of a polymorphic DNA, rep-PCR assay, and MLRFT.108

It is part of the normal human flora, typically the skin flora, and less commonly the mucosal flora. It is a facultative anaerobic bacteria. Although S. epidermidis is not usually pathogenic, patients with compromised immune systems are at risk of developing infection. These infections are generally hospital-acquired. S. epidermidis is a particular concern for people with catheters or other surgical implants because it is known to form biofilms that grow on these devices. Being part of the normal skin flora, S. epidermidis is a frequent contaminant of specimens sent to the diagnostic laboratory.Esto explica las infecciones urinarias recurrentes y muchas veces el fracaso terapéutico, ya que la bacteria cuando forma biofilms es más resistente a la presencia del antibiótico.

  1. The normal urinary tract in the female is remarkably resistant to infection. The urinary tract secretes proteins, such as Tamm-Horsfall protein, that inhibit bacterial adherence and allow the bacteria to be flushed away (161). The presence of GAG in the bladder urothelium and immunoglobin in the urine may also block bacterial adherence. The deficiency of the GAG layer in the bladder may play a role in recurrent bacterial cystitis (162).

Pero estas últimas 4 especies se aíslan rara vez de pacientes.Because voiding tends to dilute and wash away the inoculated organisms, bladder infection depends on the residual volume of urine, rate of urine flow, and frequency of voiding. Voiding not only displaces infected urine with freshly sterile urine, but also flushes out bacteria attached to the urothelium. Furthermore, urine inhibits bacterial growth with its low pH, high organic acid concentration, and very low or high osmolarity. Anaerobes are rarely seen in UTI, although they are abundant in the feces, because oxygen tension in the urine prevents their growth.Staphylococcus is immobile gram-positive bacteria round shape that inhabit the skin and mucous membranes of humans. They don’t usually cause any problems, but with the weakening of protective forces of the body can cause many diseases. For staph more often affects infants, pregnant and nursing women, and people with chronic pathologies and reduced immunity. Staph is a common hospital infection that massively affects patients of medical institutions. Staph causes inflammation after surgical interventions, installation of implants, as well as the use of intravenous catheters and similar medical instruments.Staphylococcus caprae is a Gram-positive, coccus bacteria and a member of the genus Staphylococcus. S. caprae is coagulase-negative. It was originally isolated from goats, but members of this species have also been isolated from human samples.The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, including the skin, mammary glands, placenta, seminal fluid, uterus, ovarian follicles, lung, saliva, oral mucosa, conjunctiva, biliary tract, and gastrointestinal tract. Types of human microbiota include bacteria, archaea, fungi, protists and viruses. Though micro-animals can also live on the human body, they are typically excluded from this definition. In the context of genomics, the term human microbiome is sometimes used to refer to the collective genomes of resident microorganisms; however, the term human metagenome has the same meaning.

Existen métodos semi automatizados que ayudan a la identificación del microorganismo, entre ellas está el sistema API STAPH-IDENT. Este sistema es bastante bueno y tiene mucha correlación con la identificación convencional.S. saprophyticus is identified as belonging to the genus Staphylococcus using the Gram stain and catalase test. It is identitified as a species of coagulase-negative staphylococci (CoNS) using the coagulase test. Lastly, S. saprophyticus is differentiated from S. epidermidis , another species of pathogenic CoNS, by testing for susceptibility to the antibiotic novobiocin. S. saprophyticus is novobiocin-resistant, whereas S. epidermidis is novobiocin-sensitive. [3] A staphylococcus infection or staph infection is an infection caused by members of the Staphylococcus genus of bacteria. These bacteria commonly inhabit the skin and nose where they are innocuous, but may enter the body through cuts or abrasions which may be nearly invisible. Once inside the body, the bacterium may spread to a number of body systems and organs, including the heart, where the toxins produced by the bacterium may cause cardiac arrest. Once the bacterium has been identified as the cause of the illness, treatment is often in the form of antibiotics and, where possible, drainage of the infected area. However, many strains of this bacterium have become antibiotic resistant; for those suffering these kinds of infection, the body's own immune system is the only defense against the disease. If that system is weakened or compromised, the disease may progress rapidly.

Most E. coli strains are harmless, but some serotypes can cause serious food poisoning in their hosts, and are occasionally responsible for product recalls due to food contamination. The harmless strains are part of the normal microbiota of the gut, and can benefit their hosts by producing vitamin K2, and preventing colonization of the intestine with pathogenic bacteria, having a symbiotic relationship. E. coli is expelled into the environment within fecal matter. The bacterium grows massively in fresh fecal matter under aerobic conditions for 3 days, but its numbers decline slowly afterwards.

Эпидермальный стафилококк

These pathogens may gain entry to the urinary tract by three pathways: the ascending route, the hematogenous route, and the lymphatic route. The ascending route appears to be the most important mechanism for organisms to enter the urinary tract. Normally, the urinary tract in women is sterile above the level of the distal urethra, and organisms that gain access to the bladder tend to do so from neighboring sites such as the perineum, vaginal vestibule, lower urethra, paraurethral tissues, and bowel. Women are more susceptible to UTI due to their short urethra and the decreased urethral resistance after menopause. Urinary infection via the hematogenous route is uncommon but is seen occasionally in elderly, debilitated, or immunosuppressed patients with overwhelming infections or in whom kidney infection is only part of the multisystemic involvement. Renal seeding of staphylococcal organisms and tuberculosis are almost always acquired via the hematogenous route. Large bacterial inoculums and virulent organisms are also spread through hematogenous dissemination. Although very rare, lymphatic route of infection can occur.A pesar de que generalmente se encuentra presente en una cantidad menor de 100.000 unidades formadoras de colonia por mililitro de orina (UFC/mL), se detecta persistentemente en muestras seriadas. Por eso se dice que S. saprophyticus es un patógeno bien documentado.

Staphylococcus saprophyticus apraksts - mikrobioloģiskās īpašības, izraisīto infekciju apraksts A broader range of bacteria can cause complicated UTI, and many are resistant to broad-spectrum antimicrobial agents. Although E. coli is the most common, Citrobacter species, Enterobacter species, P. aeruginosa, enterococci, and S. aureus account for a relatively higher proportion of cases compared with uncomplicated UTIs (see Fig. 51.3).1 The proportion of infections caused by fungi, especially Candida species, is increasing (see Chapter 53). Patients with chronic conditions, such as spinal cord injury and neurogenic bladder, are more likely to have polymicrobial (multiorganism) and multidrug-resistant infections.Инфекция, вызванная S. epidermidis, чаще выявляется у пожилых мужчин, онкобольных и людей, получающих химиотерапию.

Saprophytic Staphylococcus inhabits the mucous membrane of the urethra and is often the cause of cystitis in women. Staphylococcus saprophyticus is a Gram-positive coccus belonging to the genus Staphylococcus. S. saprophyticus is a common cause of community-acquired urinary tract infections. S. saprophyticus was not recognized as a cause of urinary tract infections until the early 1970s.. Staphylococcus saprophyticus es una bacteria que forma parte del grupo de Staphylococcus denominados coagulasa negativos. Es un microorganismo de importancia clínica, pues causa.. Staphylococcus aureus is a Gram-positive, round-shaped bacterium that is a member of the Firmicutes, and it is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin. It is often positive for catalase and nitrate reduction and is a facultative anaerobe that can grow without the need for oxygen. Although S. aureus usually acts as a commensal of the human microbiota it can also become an opportunistic pathogen, being a common cause of skin infections including abscesses, respiratory infections such as sinusitis, and food poisoning. Pathogenic strains often promote infections by producing virulence factors such as potent protein toxins, and the expression of a cell-surface protein that binds and inactivates antibodies. The emergence of antibiotic-resistant strains of S. aureus such as methicillin-resistant S. aureus (MRSA) is a worldwide problem in clinical medicine. Despite much research and development, no vaccine for S. aureus has been approved.A urinary tract infection (UTI) is an infection that affects part of the urinary tract. When it affects the lower urinary tract it is known as a bladder infection (cystitis) and when it affects the upper urinary tract it is known as a kidney infection (pyelonephritis). Symptoms from a lower urinary tract infection include pain with urination, frequent urination, and feeling the need to urinate despite having an empty bladder. Symptoms of a kidney infection include fever and flank pain usually in addition to the symptoms of a lower UTI. Rarely the urine may appear bloody. In the very old and the very young, symptoms may be vague or non-specific.

S. aureus относится к патогенным микроорганизмам, однако он настолько часто выявляется в мазке, что одного лишь обнаружения этой бактерии недостаточно для назначения антибактериальной терапии. По статистике до 40% мужчин являются носителями золотистого стафилококка и даже не знают о его существовании. В титре до 104 КОЕ/мл S. aureus не опасен. Превышение этого показателя – повод для начала специфической терапии. Staphylococcus saprophyticus information including symptoms, causes, diseases, symptoms, treatments, and other medical and health issues Así mismo, ha sido aislado de infecciones urinarias en niños y adolescentes de ambos sexos en ausencia de anomalías estructurales de las vías urinarias.Escherichia coli, Proteus, Klebsiella, Enterobacter and Staphylococcus saprophyticus are the most common etiologic agents in UTI. E. coli dominate in both outpatient and hospitalized populations and are the most extensively characterized regarding mechanisms of virulence.

Представляет собой условно-патогенный микроорганизм, обитающий на коже большинства людей на планете. Обнаруживается при обследовании и в половых путях мужчин, но в большинстве случаев не представляет опасности. Диагностический титр S. epidermidis – 104 КОЕ/мл. Превышение этого показателя говорит об активации эпидермального стафилококка, что происходит при значительном снижении местного и общего иммунитета.Novobiocin, also known as albamycin or cathomycin, is an aminocoumarin antibiotic that is produced by the actinomycete Streptomyces niveus, which has recently been identified as a subjective synonym for S. spheroides a member of the order Actinobacteria. Other aminocoumarin antibiotics include clorobiocin and coumermycin A1. Novobiocin was first reported in the mid-1950s.Staphylococcus is a genus of Gram-positive bacteria in the family Staphylococcaceae in the order Bacillales. Under the microscope, they appear spherical (cocci), and form in grape-like clusters. Staphylococcus species are facultative anaerobic organisms.The composition of CoNS is similar to the makeup of S. aureus, except that the teichoic acid contains glycerol in place of ribose and the cell wall lacks protein A. Determination of the genome of S. epidermidis strain ATCC 12228 (a commensal isolate not associated with disease) revealed a genome approximately 2.5 megabases in size with 2419 open reading frames, greater than 10% smaller than the published genomes of S. aureus isolates.109 In comparison with the available S. aureus genomes, ATCC 12228 contains fewer antibiotic resistance genes and lacks pathogenicity islands and a capsule locus. A homologue of the S. aureus srtA gene is present, along with nine proteins predicted to contain an LPXTG motif.Представитель этого вида относится к коккам – шаровидным микроорганизмам. По Граму окрашивается положительно. Является факультативным анаэробом, может существовать без доступа воздуха. Споры не образует. Некоторые формы стафилококка в неблагоприятных условиях способны инкапсулироваться. При посеве образует характерные группы клеток в виде виноградных гроздьев.

При развитии цистита появляется боль внизу живота. Переход инфекции на предстательную железу приводит к возникновению простатита и его характерных симптомов:Стафилококк чрезвычайно устойчив во внешней среде. Этот микроорганизм секретирует несколько токсинов, помогающих ему выживать в неблагоприятных условиях. Это и энтеротоксины, вызывающие сбой в работе ЖКТ, и поверхностные протеины, помогающие стафилококку закрепиться на поверхности клеток. Микроорганизм также синтезирует большое количество ферментов, способствующих развитию устойчивости к известным антибиотикам.Streptococcus bovis, is a species of Gram-positive bacteria that in humans is associated with urinary tract infections, endocarditis, sepsis, and colorectal cancer. S. gallolyticus is commonly found in the alimentary tract of cattle, sheep, and other ruminants, and may cause ruminal acidosis or feedlot bloat. It is also associated with spontaneous bacterial peritonitis, a frequent complication occurring in patients affected by cirrhosis.Se cree que la puerta de entrada a las vías urinarias de mujeres jóvenes se da a través del coito, donde las bacterias pueden ser arrastradas desde la vagina al tejido urinario.

La incidencia de infecciones urinarias por S. saprophyticus varía en forma considerable entre las distintas poblaciones de pacientes y las diferentes áreas geográficas. Por lo general está relacionado a infecciones recurrentes y a cálculos renales.This is most commonly seen in young women with normal urinary tracts. Antibiotic treatment shortens the duration of symptoms but may cause adverse reactions, and 20–30% are free of symptoms at 5–7 days even without antibiotics. Initial treatment with co-amoxiclav, an oral cephalosporin (e.g. cefalexin) or trimethoprim, is usually satisfactory. Current resistance rates of 20–50% among common pathogens for trimethoprim and amoxicillin threaten their value for empirical therapy in many parts of the world. Therapy should normally last for 3 days and may need to be altered once the results of bacterial sensitivity are known.Epidermis Staphylococcus can live on any parts of the skin and mucous membranes. A healthy person is easy to cope with it, but the people in the intensive care unit, the bacterium penetrates the body, causing severe diseases such as sepsis (blood poisoning), endocarditis (inflammation of the inner lining of the heart), etc.Staphylococcus saprophyticus es un microorganismo anaerobio facultativo que habita en el tracto gastrointestinal de los humanos, siendo el recto el sitio más frecuente de colonización, seguido por la uretra, la orina y el cuello uterino.

CoNS are a heterogeneous group of organisms that have been divided into 32 species [36]. The following 15 species of CoNS are found as members of the normal human flora: S. epidermidis, Staphylococcus haemolyticus, Staphylococcus saprophyticus, Staphylococcus capitis, Staphylococcus warneri, Staphylococcus hominis, Staphylococcus xylosus, Staphylococcus cohnii, Staphylococcus simulans, Staphylococcus auricularis, Staphylococcus saccharolyticus, Staphylococcus caprae, Staphylococcus pasteuri, Staphylococcus lugdunensis, and Staphylococcus schleiferi [36,58]. Among these species, several occupy very specific niches on the skin. S. capitis is most abundant on the head, where sebaceous glands are plentiful. S. auricularis has a striking predilection for the external auditory canal. S. hominis and S. haemolyticus are most common in the axillae and the pubic area, where apocrine glands are numerous.-Algunas pruebas pueden dar resultados variables como es el caso de la fermentación de lactosa y manitol y la susceptibilidad a la bacitracina, la cual puede ser sensible o resistente. 1996 - Staphylococcus saprophyticus subsp. saprophyticus (Fairbrother 1940) Shaw et al. Isolated from skin & urine samples (subsp. saprophyticus) and from upper respiratory tract of healthy.. In uncomplicated cystitis, more than 95% of infections are caused by a single organism, most commonly Escherichia coli (80–90% of cases). Staphylococcus saprophyticus accounts for 10–20% of cases in young women, especially during late summer and autumn (Table 57-3).5 A small number of types of uropathogenic E. coli (UPEC) account for most UTIs and fluoroquinolone and trimethoprim–sulfamethoxazole-resistant clones have become widespread. UPEC sequence type 131 has also acquired ESBL multiresistance genes (mostly CTX-M-type),6 and community-associated infections with this organism are now a major clinical problem in the USA, Europe, India and elsewhere.7,8 In many cases there are no discernible risk factors but others are healthcare-associated. Many infected patients carry a high load of these organisms in the feces.9 Carbapenem-resistant Klebsiella pneumoniae bacteriuria is a much less common etiology, but is associated with multiple co-morbidities and healthcare exposure.10

Staphylococcus saprophyticus (ATCC® 15305) growing around a HardyDisk™ Novobiocin Differentiation Disk (Cat. no. Z7291). Incubated aerobically on TSA (Cat. no Paper with words staphylococcus saprophyticus and glasses. Medical concept Staphylococcus epidermidis (staph epidermidis, S.epidermidis / epidermis) is a part of a normal S.epidermidis and S. saprophyticus often cause hospital acquired urinary infections, mostly in old..

Otros factores de riesgo son: uso de sondas urinarias, embarazo, hipertrofia prostática benigna entre otras. This study included 502 staphylococcus strains; Staphylococcus saprophyticus (297 strains) S. cohnii (47), S. xylosus (10), S. epidermidis (67) and S. aureus (81). Mitomycin C induction was.. Staphylococcus saprophyticus gram stain. S. Saprophyticus is a common cause of community-acquired urinary tract infections. S. saprophyticus is found in the normal flora of the female genital.. O Staphylococcus saprophyticus, ou S. saprophyticus, é uma bactéria gram-positiva que pode ser encontrada no sistema genital de homens e mulheres, sem causar qualquer sinal ou sintoma

S. saprophyticus was not recognized as a cause of urinary tract infections until the early 1970s, more than 10 years after its original demonstration in urine specimens. Prior to this, the presence of coagulase-negative staphylococci (CoNS) in urine specimens was dismissed as contamination.[ citation needed ]Speciation of CoNS is accomplished on the basis of a series of biochemical characteristics, simplified in recent years by the commercial availability of miniaturized kits [36]. Differentiation of two strains belonging to the same species (subspeciation) represents a more difficult problem, however. Analogous to the situation with S. aureus, contemporary techniques for distinguishing strains of a given species include PFGE and MLST [59]. The composition of CoNS is quite similar to the makeup of S. aureus except that the teichoic acid contains glycerol in place of ribose, and the cell wall lacks protein A. Determination of the genome of S. epidermidis strain ATCC 12228 (a commensal isolate not associated with disease) revealed a genome approximately 2.5 Mb in size with 2419 open reading frames, greater than 10% smaller than the published genomes of S. aureus isolates [60]. Compared with the available S. aureus genomes, ATCC 12228 contains fewer antibiotic resistance genes and lacks pathogenicity islands and a capsule locus. A homologue of the S. aureus srtA gene is present, along with nine proteins predicted to contain an LP(X)TG motif.При возникновении таких симптомов нужно пройти обследование у уролога.
