Enzymes that cause coagulation in plasma by forming a complex with human PROTHROMBIN. Coagulases are produced by certain STAPHYLOCOCCUS and YERSINIA PESTIS. Staphylococci produce two types of coagulase: Staphylocoagulase, a free coagulase that produces true clotting of plasma, and Staphylococcal clumping factor, a bound coagulase in the cell wall that induces clumping of cells in the presence of fibrinogen.
A genus of gram-positive, facultatively anaerobic, coccoid bacteria. Its organisms occur singly, in pairs, and in tetrads and characteristically divide in more than one plane to form irregular clusters. Natural populations of Staphylococcus are found on the skin and mucous membranes of warm-blooded animals. Some species are opportunistic pathogens of humans and animals.
Staphylococcal Protein A
A protein present in the cell wall of most Staphylococcus aureus strains. The protein selectively binds to the Fc region of human normal and myeloma-derived IMMUNOGLOBULIN G. It elicits antibody activity and may cause hypersensitivity reactions due to histamine release; has also been used as cell surface antigen marker and in the clinical assessment of B lymphocyte function.
A diuretic and renal diagnostic aid related to sorbitol. It has little significant energy value as it is largely eliminated from the body before any metabolism can take place. It can be used to treat oliguria associated with kidney failure or other manifestations of inadequate renal function and has been used for determination of glomerular filtration rate. Mannitol is also commonly used as a research tool in cell biological studies, usually to control osmolarity.
A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis.
Bacterial Typing Techniques
The presence of viable bacteria circulating in the blood. Fever, chills, tachycardia, and tachypnea are common acute manifestations of bacteremia. The majority of cases are seen in already hospitalized patients, most of whom have underlying diseases or procedures which render their bloodstreams susceptible to invasion.
Reagent Kits, Diagnostic
Microbial Sensitivity Tests
Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.
Any member of the class of enzymes that catalyze the cleavage of the substrate and the addition of water to the resulting molecules, e.g., ESTERASES, glycosidases (GLYCOSIDE HYDROLASES), lipases, NUCLEOTIDASES, peptidases (PEPTIDE HYDROLASES), and phosphatases (PHOSPHORIC MONOESTER HYDROLASES). EC 3.
Electrophoresis, Gel, Pulsed-Field
Gel electrophoresis in which the direction of the electric field is changed periodically. This technique is similar to other electrophoretic methods normally used to separate double-stranded DNA molecules ranging in size up to tens of thousands of base-pairs. However, by alternating the electric field direction one is able to separate DNA molecules up to several million base-pairs in length.

Epidemiological characterization of methicillin-resistant Staphylococcus aureus isolated in the North West of England by protein A (spa) and coagulase (coa) gene polymorphisms. (1/806)In a comparative study, isolates of methicillin-resistant Staphylococcus aureus (MRSA) with known pulsed-field gel electrophoresis (PFGE) and bacteriophage type were analysed by polymerase chain reaction (PCR) and restriction fragment length polymorphisms (RFLP) for additional discriminatory subtyping information. PFGE was previously performed using standardized, commercially available kits and pre-programmed software. Isolates were examined for coagulase (coa) and protein A (spa) gene polymorphisms following PCR amplification of the coa hypervariable and spa repeat regions. Coa gene RFLPs produced a total of 38 distinct combined patterns after digestion with HaeIII and AluI and identified the predominant epidemic (EMRSA) types 15 and 16. A unique HaeIII restriction site was identified by RFLP and sequence analysis in the coa gene for EMRSA 15 but not EMRSA 16. The spa gene PCR yielded a total of 14 different profiles ranging from 3-18 repeats with the 2 predominant EMRSA types falling into 2 distinct groups. PCR detection of coa and spa polymorphisms offer a rapid preliminary strain identification and discriminatory subtyping information for surveillance of MRSA. (+info)
Changing susceptibilities of coagulase-negative staphylococci to teicoplanin in a teaching hospital. (2/806)The susceptibility of two collections of coagulase-negative staphylococci (CNS) isolated from clinical specimens for teicoplanin and vancomycin were compared. They comprised 91 and 101 isolates, collected in 1985 and 1994 respectively, from different departments of a teaching hospital. MICs of vancomycin and teicoplanin were determined by a modified Etest method. Additionally, a disc diffusion test was performed for teicoplanin. All isolates were susceptible to vancomycin (MIC < or = 4 mg/L). Two of the 91 isolates collected in 1985 were intermediate to teicoplanin (MIC between 8 and 32 mg/L), whereas in 1994 the number of intermediate isolates was 20 out of 101 (P < 0.01). The correlation between MICs, as determined by the modified Etest assay, and disc diffusion zones was poor (r = -0.35). Results show that resistance to teicoplanin in CNS has increased in the study hospital over a period of 9 years. This increase is likely to be correlated with the introduction of teicoplanin. Furthermore, a disc diffusion method does not appear to be the first method of choice for detection of strains of CNS with diminished susceptibility to teicoplanin. (+info)
Rapid identification of Staphylococcus aureus by using fluorescent staphylocoagulase assays. (3/806)Two rapid (1-h) assays for the detection of Staphylococcus aureus staphylocoagulase were developed by using the fluorogenic thrombin substrates N-t-boc-Val-Pro-Arg-7-amido-4-methylcoumarin (VPA) and N-t-boc-beta-benzyl-Asp-Pro-Arg-7-amido-4-methylocoumarin (BB). The assays were compared to the tube coagulase test and latex agglutination (LA) (Sanofi Diagnostics Pasteur, Guildford, Surrey, United Kingdom) by using 406 clinical isolates of staphylococci, and they produced positive and negative predictive values of 99.2 and 99. 1% for LA, 98.9 and 92.7% for VPA, and 98.9 and 99.1% for BB. Fluorescent assays used colonies from solid media, thereby eliminating the need for broth cultures, and were performed in microtiter trays, thus making them suitable for large-scale screening.

The Staphylococcus aureus rsbW (orf159) gene encodes an anti-sigma factor of SigB. (4/806)SigB, a newly discovered alternative sigma factor of Staphylococcus aureus, has been shown to play an important role in stress responses and the regulation of virulence factors. The rsbW (orf159) gene is immediately upstream of sigB. Its gene product is homologous to Bacillus subtilis RsbW which under appropriate conditions binds to B. subtilis SigB and functions as an anti-sigma factor or negative posttranslational regulator. To define the function of S. aureus RsbW, both the S. aureus SigB and RsbW proteins were expressed in Escherichia coli and purified. Cross-linking experiments with these purified proteins revealed that RsbW was capable of specific binding to SigB. In an in vitro transcription runoff assay, RsbW prevented SigB-directed transcription from the sar P3 promoter, a known SigB-dependent promoter, and the inhibitory activity of RsbW was found to be concentration dependent. We also identified SigB promoter consensus sequences upstream of the genes encoding alkaline shock protein 23 and coagulase and have demonstrated SigB and RsbW dependence for the promoters in vitro. These results show that RsbW is a protein sequestering anti-sigma factor of S. aureus SigB and suggest that SigB activity in S. aureus is regulated posttranslationally. (+info)
Use of semi-quantitative and quantitative culture methods and typing for studying the epidemiology of central venous catheter-related infections in neonates on parenteral nutrition. (5/806)To study the epidemiology - especially the impact of contaminated stopcocks - on central venous catheter (CVC) infection and catheter-related sepsis (CRS), semi-quantitative (SQ) and quantitative (Q) culture methods and typing of coagulase-negative staphylococci (CNS) were employed in 49 neonates with clinical signs of sepsis while receiving parenteral nutrition in the paediatric intensive care unit. The patients were divided into two groups according to stopcock contamination: group A consisted of 18 patients (36%) with contaminated stopcocks and group B consisted of 31 patients (64%) with sterile stopcocks. Five specimens were obtained from each patient, in addition to that from the stopcock: a swab taken from the skin surrounding the catheter puncture site; the CVC tip; the intradermal segment (IDC); and samples of parenteral fluid and blood. A total of 294 specimens (392 sites) was cultured and micro-organisms were identified. All CNS isolated were typed by biotyping, antibiogram, plasmid analysis and pulsed-field gel electrophoresis (PFGE), and the discriminatory power of the typing methods was compared. The CVC tips were infected in 25 patients (51%); 15 (83%) in group A and 10 (32%) in group B. Sepsis was detected in 24 neonates (49%), 13 in group A and 11 in group B. This was catheter-related in 15 patients (63%), 12 in group A and 3 in group B. CNS were recovered from 13 (52%) of 25 infected CVCs, nine in group A and four in group B. Sixty-five CNS isolates were recovered from these patients and belonged to 14 biotypes, 22 antibiograms, 22 plasmid profiles and 26 PFGE types. Typing showed that in six of nine patients in group A, CNS of the same type were recovered from the catheter tip and the stopcock, in one patient the catheter tip and skin isolates were the same and in two others the catheter tip isolates were different from stopcock and skin isolates. In all four patients in group B, different CNS types were recovered from CVC tips and skin. Bacteraemia was caused by CNS in 14 patients (58%), six in group A and eight in group B. Typing confirmed that nine cases (six in group A and three in group B) were catheter-related but five were not. SQ and Q culture methods and typing, especially by PFGE, allowed the study to determine that bacteria from contaminated stopcocks were frequently the source of CVC infection and CRS. (+info)
Oxacillin susceptibility testing of staphylococci directly from Bactec Plus blood cultures by the BBL Crystal MRSA ID system. (6/806)The BBL Crystal MRSA ID test (Becton Dickinson) was applied directly to blood culture vials containing clusters of gram-positive cocci. The sensitivity and specificity of the test were 84 and 100% and 54 and 100% for vials containing Staphylococcus aureus and coagulase-negative staphylococci, respectively. This test is a reliable method for direct detection of methicillin resistance in positive blood culture vials when S. aureus is identified in parallel by rapid identification procedures. (+info)
Analysis of genomic diversity within the Xr-region of the protein A gene in clinical isolates of Staphylococcus aureus. (7/806)Protein A of Staphylococcus aureus contains a polymorphic Xr-region characterized by a tandem repeat of eight amino acid units. In this study, the diversity of genes encoding the repeat regions and their relatedness among S. aureus strains was analyzed. Ten different protein-A types characterized by repeat numbers 4-13 were identified in a total of 293 clinical isolates. The protein-A type with 10 repeat units (10 repeats) in the Xr-region was most frequently detected in methicillin-resistant S. aureus, whereas the majority of methicillin-susceptible strains were distributed almost evenly into protein-A types with 7-11 repeats. Strains that belonged to a single coagulase type were classified into multiple protein-A types, e.g. strains with the common coagulase types II and VII were differentiated into 7 and 8 protein-A types, respectively. Nucleotide sequence analysis of the Xr-region of 42 representative strains revealed the presence of 37 different genotypes (spa types), which were constituted by a combination of several of 24 different repeat unit genotypes. Based on the similarity in arrangement of repeat unit genotypes, 34 strains with different repeat numbers were classified into 5 genetic clusters (C1-C5). The clusters C1, C2 and C3 consisted exclusively of strains with identical coagulase types II, III, and IV, respectively. These findings suggested that the protein-A gene of S. aureus has evolved from a common ancestral clone in individual clusters independently. (+info)
Coagulase gene polymorphism of Staphylococcus aureus isolates from dairy cattle in different geographical areas. (8/806)The objectives of this study were to investigate the coagulase gene polymorphism of Staphylococcus aureus isolates obtained from bovine mastitic milk and to determine the resistance of predominant and rare coagulase genotypes to bovine blood neutrophil bactericidal activities. A total of 453 isolates were collected from four countries: the Czech Republic, France, Korea and the United States. The isolates were subtyped into 40 types by restriction fragment length polymorphism (RFLP) of the coagulase gene. Twenty-three strains from predominant and rare genotypes were evaluated for their ability to resist neutrophil bactericidal activities. There were significant (P < 0.01) differences in the average percent neutrophil killing of the predominant (16.7%) and rare (39.7%) genotypes when bacteria were opsonized with antiserum. The results indicate that the profiles of coagulase genotype differ among geographic locations, and only a few genotypes prevail in each location. In addition, the predominant genotypes were more resistant to neutrophil bactericidal activities than rare genotypes. (+info)

PURPOSE: To evaluate the fluoroquinolone susceptibilities of ocular isolate coagulase-negative staphylococci (CoNS), identified at the Microbiology Laboratory - UNIFESP. DESIGN: Experimental laboratory investigation. METHODS: The minimum inhibitory concentrations (MICs) of 21 strains of methicillin-resistant coagulase-negative staphylococci (MRCoNS) and 22 methicillin-sensitive coagulase-negative staphylococci (MSCoNS) to ciprofloxacin, ofloxacin, gatifloxacin and moxifloxacin were determined, using the E-test method standardized by the Clinical and Laboratory Standards Institute (CLSI/NCCLS). RESULTS: The MIC90s (µg/ml) for the second generation of tested fluoroquinolones were higher than the fourth generation, especially for the methicillin-resistant coagulase-negative staphylococci group. CONCLUSION: Our results indicate that methicillin-sensitive coagulase-negative staphylococci are more susceptible to quinolones than are methicillin-resistant coagulase-negative staphylococci and that ...

TY - JOUR. T1 - Determination of the chromosomal relationship between mecA and gyrA in methicillin-resistant coagulase-negative staphylococci. AU - Fey, Paul D.. AU - Climo, Michael W.. AU - Archer, Gordon L.. PY - 1998/2. Y1 - 1998/2. N2 - mecA, the gene that mediates methicillin resistance, and its accompanying mec locus DNA, insert near the gyrA gene in Staphylococcus aureus. To investigate whether there is a similar relationship between mecA and gyrA in coagulase-negative staphylococci (CNS), mecA- and gyrA-specific DNA fragments were used to probe methicillin-resistant isolates of Staphylococcus epidermidis (MRSE) (n = 11) and Staphylococcus haemolyticus (MRSH) (n = 11). The gyrA probe hybridized to the same SmaI DNA fragment as the mecA probe in all strains tested. However, since the size of the SmaI fragments containing meca and gyrA varied from 73 to 600 kb, the distance between the two genes was determined more precisely. Cloned mecA or gyrA fragments plus vector sequences each ...

Role of Staphylococcus aureus coagulase and clumping factor in pathogenesis of experimental endocarditis. | Infection and...
The pathogenic role of staphylococcal coagulase and clumping factor was investigated in the rat model of endocarditis. The coagulase-producing and clumping factor-producing parent strain Staphylococcus aureus Newman and a series of mutants defective in either coagulase, clumping factor, or both were tested for their ability (i) to attach in vitro to either rat fibrinogen or platelet-fibrin clots and (ii) to produce endocarditis in rats with catheter-induced aortic vegetations. In vitro, the clumping factor-defective mutants were up to 100 times less able than the wild type strain to attach to fibrinogen and also significantly less adherent than the parents to platelet-fibrin clots. Coagulase-defective mutants, in contrast, were not altered in their in vitro adherence phenotype. The rate of in vivo infection was inoculum dependent. Clumping factor-defective mutants produced ca. 50% less endocarditis than the parent organisms when injected at inoculum sizes infecting, respectively, 40 and 80% ...

Coagulase negative staphylococci (CoNS) are important reservoirs of antibiotic resistance genes and associated mobile genetic elements and are believed to contribute to the emergence of successful methicillin resistant Staphylococcus aureus (MRSA) clones. Although, these bacteria have been linked to various ecological niches, little is known about the dissemination and genetic diversity of antibiotic resistant CoNS in general public settings. Four hundred seventy-nine samples were collected from different non-healthcare/general public settings in various locations (n = 355) and from the hands of volunteers (n = 124) in London UK between April 2013 and Nov 2014. Six hundred forty-three staphylococcal isolates belonging to 19 staphylococcal species were identified. Five hundred seventy-two (94%) isolates were resistant to at least one antibiotic, and only 34 isolates were fully susceptible. Sixty-eight (11%) mecA positive staphylococcal isolates were determined in this study. SCCmec types were fully

Antimicrobial resistance patterns and gene coding for methicillin resistance (mecA) were determined in 25 S. aureus and 75 Coagulase Negative Staphylococci (CNS) strains isolates from half-udder milk samples collected from goats with subclinical mastitis. Fourteen (56.0%) S. aureus and thirty-one (41.3%) CNS isolates were resistant to one or more antimicrobial agents. S. aureus showed the highest resistance rate against kanamycin (28.0%), oxytetracycline (16.0%), and ampicillin (12.0%). The CNS tested were more frequently resistant to ampicillin (36.0%) and kanamycin (6.7%). Multiple antimicrobial resistance was observed in eight isolates, and one Staphylococcus epidermidis was found to be resistant to six antibiotics. The mecA gene was not found in any of the tested isolates. Single resistance against β-lactamics or aminoglicosides is the most common trait observed while multiresistance is less frequent. ...
Coagulase - Wikipedia
Coagulase is a protein enzyme produced by several microorganisms that enables the conversion of fibrinogen to fibrin. In the laboratory, it is used to distinguish between different types of Staphylococcus isolates. Importantly, S. aureus is generally coagulase-positive, meaning that coagulase negativity usually excludes S. aureus. However it is now known that not all S. aureus are coagulase-positive. It is also produced by Yersinia pestis. Coagulase reacts with prothrombin in the blood. The resulting complex is called staphylothrombin, which enables the enzyme protease to convert fibrinogen, a plasma protein produced by the liver, to fibrin. This results in clotting of the blood. Coagulase is tightly bound to the surface of the bacterium S. aureus and can coat its surface with fibrin upon contact with blood. The fibrin clot may protect the bacterium from phagocytosis and isolate it from other defenses of the host.The fibrin coat can therefore make the bacteria more virulent. Bound coagulase is ...

Rapid colonization with methicillin-resistant coagulase-negative staphylococci after surgery - Zurich Open Repository and...
BACKGROUND: Antimicrobial resistance may compromise the efficacy of antibiotic prophylaxis before surgery. The aim of this study was to measure susceptibility and clonal distribution of coagulase-negative staphylococci (CoNS) colonizing the skin around the surgery access site before and after the procedure. METHODS: From March to September 2004, a series of 140 patients undergoing elective major abdominal surgery were screened for CoNS colonization at admission and 5 days after surgery. All isolates were tested for antibiotic susceptibility and genotyped by pulsed-field gel electrophoresis (PFGE). RESULTS: Colonization rates with CoNS at admission and after surgery were 85% and 55%, respectively. The methicillin-resistant CoNS rate increased from 20% at admission to 47% after surgery (P = 0.001). The PFGE pattern after surgery revealed more patients colonized with identical clones: 8/140 patients (8/119 strains) and 26/140 patients (26/77 strains), respectively (P , 0.001). CONCLUSIONS: Our ...
Characterization of coagulase-negative staphylococcal isolates from blood with reduced susceptibility to glycopeptides and...
Coagulase-negative staphylococci (CoNS) are a major cause of nosocomial blood stream infection, especially in critically ill and haematology patients. CoNS are usually multidrug-resistant and glycopeptide antibiotics have been to date considered the drugs of choice for treatment. The aim of this study was to characterize CoNS with reduced susceptibility to glycopeptides causing blood stream infection (BSI) in critically ill and haematology patients at the University Hospital Tor Vergata, Rome, Italy, in 2007. Hospital microbiology records for transplant haematology and ICU were reviewed to identify CoNS with elevated MICs for glycopeptides, and isolates were matched to clinical records to determine whether the isolates caused a BSI. The isolates were tested for susceptibility to new drugs daptomicin and tigecycline and the genetic relationship was assessed using f-AFLP. Of a total of 17,418 blood cultures, 1,609 were positive for CoNS and of these, 87 (5.4%) displayed reduced susceptibility to
Clinical: Culture Negative Surgical Site Infections - OurMed
Legionella species are generally susceptible to fluroquinolones or macrolides Small-colony variant Staphylococcus aureus (SCV) These are a form of Staphylococcus aureus. They are not recognised on routine culture media as they grow slowly. They also have a delayed coagulase positive test which can be delayed up to 24 hours. The common (or the wild type) S aureus compared takes just 4 hours to exhibit coagulase positivity. For this reason, these are commonly identified as coagulase-negative staphylococci. The best way to recognise them is to incubate for at least 3 days and look for pinpoint colonies, and then to await the coagulase positive test. These microbes have a reduced metabolic capacity and are therefore less pathogenic. However, it can persist intracellularly and cause chronic infection, and are resistant to routine antibiotics (which are effective against the wild type). They are very common in patients who have received or are on antibiotics, especially aminoglycosides. SSIs caused ...
Staphylococcus - Wikipedia
One of the most important phenotypical features used in the classification of staphylococci is their ability to produce coagulase, an enzyme that causes blood clot formation. Seven species are currently recognised as being coagulase-positive: S. aureus, S. delphini, S. hyicus, S. intermedius, S. lutrae, S. pseudintermedius, and S. schleiferi subsp. coagulans. These species belong to two separate groups - the S. aureus (S. aureus alone) group and the S. hyicus-intermedius group (the remaining five). An eighth species has also been described - Staphylococcus leei - from patients with gastritis.. S. aureus is coagulase-positive, meaning it produces coagulase. However, while the majority of S. aureus strains are coagulase-positive, some may be atypical in that they do not produce coagulase. S. aureus is catalase-positive (meaning that it can produce the enzyme catalase) and able to convert hydrogen peroxide (H2O2) to water and oxygen, which makes the catalase test useful to distinguish ...
Difference between Staphylococcus and Streptococcus - microbeonline
Hello Eric, Streptococcus genus contains both beta-hemolytic and alpha hemolytic species. S. pyogenes and S.agalactiae are beta-hemolytic but S.pneumoniae and viridans streptococci (common name for various Streptococci species that gives alpha hemolysis) are alpha hemolytic. In Staphylococci, S.aureus is the pathogenic one but S. epidermidis, S. saprophyticus are mostly commensal (normal flora) and occasionally be pathogenic. So common phrase Coagulase Negative Staphylococci (CONS) is used for them; (S. aureus is coagulase positive).. ...
Simplified scheme for routine identification of human Staphylococcus species. | Journal of Clinical Microbiology
From a total of 40 characters that were previously used to differentiate species of staphylococci, 13 key characters were selected to make a simplified scheme that could be easily used by the routine clinical laboratory for identifying human staphylococci. These key characters included coagulase activity, hemolysis, nitrate reduction, and aerobic acid production from fructose, xylose, arabinose, ribose, maltose, lactose, sucrose, trehalose, mannitol, and xylitol. In the simplified scheme, 924 strains of staphylococci were placed into 11 positions, each of which contained the major portion (greater than or equal to 80%) of strains of one of the recognized species. Several positions contained a rare or few uncommon strains of one or more additional species and these could be resolved on the basis of other key characters. ...

About Coagulase Positive Staphylococci | EURL
The incubation period and severity of symptoms observed depend on the amount of enterotoxins ingested and the susceptibility of each person. Initial symptoms, nausea followed by incoercible characteristic vomiting (in spurts), appear within 30 minutes to eight hours (three hours on average) after ingesting the contaminated food. Other commonly described symptoms are abdominal pain, diarrhoea, dizziness, shivering and general weakness sometimes associated with a moderate fever. In the most severe cases, headaches, prostration and low blood pressure have been reported. In the majority of cases, recovery occurs within 18 to 24 hours without specific treatment, while diarrhoea and general weakness can last 24 hours or longer. Death is rare, occurring in the most susceptible people to dehydration (infants and the elderly) and people affected by an underlying illness ...

Le infezioni catetere vascolare correlate: risultati di tre anni di sorveglianza (2001-2003) | Microbiologia Medica
Central venous catheter represents a major source of nosocomial bloodstream infection, which cause considerable excess morbidity.The diagnosis of catheter-related infections relies on the presence of clinical manifestation of infection and the evidence of colonization of the catheter tip by bacteria or fungi. The most frequent pathogens were Gram-positive organisms, mainly coagulase negative staphylococci, followed by Gram-negative and mycetes. During the years 2001-2003 we examined 2079 vascular catheters, of which 896 were positive for bacterial and fungal species. Of these, 675 (75,3%) involved Gram-positive bacterial, 145 (16,2%) Gram-negative and 76 (8,5%) mycetes ...

Aims: This study was undertaken to determine the prevalence and pathogenicity of coagulase-negative staphylococci in clinical samples and to study the antibiotic-sensitivity pattern of the coagulase-negative isolates. Methods: A prospective study was conducted over a period of two years on patients admitted in the Sher-i-Kashmir Institute of Medical Sciences. Blood, urine, pus, catheter tips, cerebrospinal fluid and peritoneal fluid samples of patients who fulfilled the criteria for being labeled as nosocomial were cultured.. Results: One hundred and six strains of coagulase negative staphylococci were isolated from the samples and among them 90 isolates were identified as Staphylococcus epidermidis (84.90%). Most of the coagulase-negative staphylococci isolates were resistant to penicillin, cephalosporins and fluoroquinolones. Methicillin resistance was found in a significant number of coagulase-negative isolates. All the isolates were found to be sensitive to vancomycin.. Conclusions: The ...

Vancomycin Study: Treatment of Catheter Related Bloodstream Infection Caused by Coagulase Negative Staphylococcus - Full Text...
Patients admitted into the Intensive Care Unit (ICU) have an intravenous (IV) catheter (small plastic tube) placed in their vein. Very occasionally (4 times out of 100) the insertion of an intravenous catheter may cause an infection in the blood. It has been shown that the removal of the catheter and the insertion of a new one at a new site helps to get rid of this infection. Sometimes, antibiotics are also given.. Vancomycin is the antibiotic given intravenously (into the vein) to treat these catheter-related infections. At Vancouver General Hospital, some physicians may not give any vancomycin at all whereas others may treat with intravenous (IV) vancomycin for one to fourteen days.. Since there are a lack of data to support the length of IV vancomycin therapy, the investigators would like to find out if two days of IV vancomycin are as good as seven days.. Therefore, the purpose of this study is to determine if two days of IV vancomycin are as good as seven days for the treatment of ...
Staphylococcus aureus</I> and Coagulase-Negative Staphylococci: Virulence, Antimicrobial Resistance and Molecular...
The book covers updated topics on the genus Staphylococcus, including the latest discoveries. In each chapter, the author discusses the results obtained and published during her more than 20 years as a researcher in this area. The book is divided into eight chapters, with a presentation of the genus Staphylococcus, current classification, general characteristics of these bacteria and the clinical significance of coagulase-negative staphylococci (CoNS), which are often classified as mere blood culture contaminants, but are the etiological agents most commonly associated with neonatal infections and peritonitis in patients undergoing peritoneal dialysis. Coagulase-negative staphylococci can colonize the surface of catheters and produce an extracellular polysaccharide that leads to the formation of biofilms which potentiate their pathogenicity. The book also focuses on the identification of CoNS, virulence factors responsible for the symptoms and severity of infections caused by Staphylococcus spp. ...

Risk factors for oxacillin/methicillin resistance in coagulase-negative staphylococci. - Nuffield Department of Medicine
The clinical variables associated with isolation of oxacillin- and methicillin-resistant, coagulase-negative staphylococci (CNS) from blood cultures of hospitalized patients were studied. One hundred CNS strains (49 oxacillin-susceptible; 51 oxacillin-resistant) isolated consecutively from one of two or more sets of blood cultures were collected. Only two variables were independently associated with recovery of oxacillin/methicillin-resistant strains by a multivariate analysis: length of hospital stay | 10 days (OR 5.2, 95% CI = 1.7-15.7), and administration of antimicrobial agents in the previous 14 days (OR 4.5, 95% CI = 1.7-11.7). Analysis of the antibiotics administered indicated that only beta-lactams were associated with a statistically significant risk of resistance to oxacillin/methicillin (OR of beta-lactams vs no antibiotics = 6.94, 95% CI = 1.9-25.3; OR of non-beta-lactams vs no antibiotics = 2.64, 95% CI = 0.8-8.3).

Treatment of Post-operative Endophthalmitis - touchOPHTHALMOLOGY
endophthalmitis has been reported as a consequence of nearly every type of ocular surgery, but is most common following cataract surgery. Numerous reports have demonstrated that Gram-positive bacteria cause the vast majority of post-operative endophthalmitis cases. Coagulase-negative staphylococcal isolates are the most common. Most intraocular infections resulting from infection with coagulase-negative staphylococci can be treated with antibiotic and anti-inflammatory agents, resulting in restoration of partial or complete vision. However, the more virulent the bacterial strain, the more devastating the visual outcome. Intraocular infections with Staphyloccus aureus, enterococci, Bacillusor Gram-negative strains are often intractable, and blindness or loss of the eye itself is not uncommon. The therapeutic success of treating post-operative endophthalmitis depends largely on accurate and prompt diagnosis. Antibiotic therapy can be topical, sub-conjunctival, systemic or intravitreal.

Avicenna Journal of Clinical Microbiology and Infection - 3, 1
Results: The results showed 91 isolates (56.88%) were coagulase-positive, and 69 isolates (43.12%) were coagulase-negative Staphylococcus aureus (CNSA). Out of 91 (56.88%) coagulase-positive staphylococci, 32 isolates (35.16%) were resistant to cefoxitin, and 30 isolates (32.96%) were resistant to oxacillin, using disc diffusion method. PCR revealed the presence of the femA gene (510 bp band) in all coagulase-positive isolates (100%), and the mecA gene (513 bp band) was detected in 32 isolates (35.16%); out of 32 MRSA isolates, 13 isolates (40.62%) were positive for presence of the luk-pv gene (433 bp band). ...
Structural Comparison of Three Types of Staphylococcal Cassette Chromosome mec Integrated in the Chromosome in Methicillin...
We have shown that there are at least three distinct types of SCCmec in the chromosome of MRSA worldwide. SCCmec was defined as the DNA element on the MRSA chromosome demarcated by a pair of direct repeats and inverted repeats, havingccr genes required for its movement and carrying themecA gene (14, 17). As far as we could judge from the structure of the two elements newly identified in this study, they seem to constitute a family of SCCmec together with N315-type SCCmec.. The mecA gene is considered to have originated in some coagulase-negative staphylococcus species (36) and was then transferred into S. aureus to generate MRSA (1,13, 32). It is likely that SCCmec serves as the carrier of the mecA gene moving across staphylococcal species, since mecA genes in other staphylococcal species have never been found without the accompaniment of SCCmec-like structure (T. Ito and Y. Katayama, unpublished observation). Since both ccrA and ccrB genes are required for the integration event, we considered ...

Clinical consequences of using PNA-FISH in Staphylococcal bacteraemia - Forskning - Region Hovedstaden
To optimize patient treatment and rational use of antimicrobials, it is important to provide fast information on findings in blood-cultures (BCs). The purpose of this study was to evaluate the impact of using peptide nucleic acid fluorescence in situ hybridization (PNA-FISH) on positive BCs containing Gram-positive cocci in clusters to differentiate between Staphylococcus aureus (SA) and coagulase negative staphylococci (CoNS) on the prescribed antimicrobial therapy and on the number of contacts between microbiologist and clinician. All cases of positive BCs in our laboratory with SA or CoNS in the year 2011 were identified and the charts were reviewed retrospectively. The group of patients with BCs tested with PNA-FISH was compared to the group of patients with untested BCs. A total of 200 patients with SA and 725 patients with CoNS were included. The mean number of contacts was 0.82 when PNA-FISH showed CoNS and 1.39 when PNA-FISH was not done (p ...
how to identify staphylococcus species using selective agars - UW Milk Quality
Determining the cause of mastitis is important because not all cases of mastitis benefit from antibiotic therapy. For instance, Gram positive bacteria, such as Staph aureus and coagulase negative behave differently in the cow and have different responses to therapy. Being able to identify between the two can help us make appropriate treatment decisions for managing mastitis in our herds. One way to do that is through on farm culturing. In this episode, Dr. Pamela Ruegg teaches us how to identify Staphylococcus species on our cultured media plates whether we are using bi-, tri- or quad plates..

Distribution of Coagulase-Negative Staphylococci and Antibiotic Resistance
related infectious diseases in recent years. CoNS has a symbiotic relationship with humans in a normal environment, but it can become a dangerous pathogen when immune function is not normal, such as surgery or treatment. Besides, if CoNS are identified in blood cultures, it remains a serious healthcare problem whether infection or a contaminant (Muñoz-Gamito et al., 2020). Recently, it was confirmed that the treatment for surgical wound infection and the separation rate of CoNS from the joint around the prosthesis were increased, and the infection rate was also increased in septic patients. Also, the abuse and misuse of antibiotics, and antibiotic-resistant CoNS, which is caused when appropriate treatment was not conducted, are also becoming a problem in the community. After all, CoNS has been regarded as a contaminant, however its importance has increased in relation to various clinical diseases. Therefore, a research of CoNS on the distribution in variable diseases and antibiotic-resistant ...

Staph Infection- What is it? How Dangerous is it? Symptoms and Treatment
Health care professionals can determine that its a staph infection by taking a culture (a swab with a giant Q-tip) from the infected site. Once staph is diagnosed, your provider prescribes antibiotics that kill that specific bacterial strain.. Hospitals are trying to stop staph infections, because most hospital patients are at risk, and because drug-resistant strains of staph (versions of the bacteria not vulnerable to the antibiotics used to treat staph infections) are becoming more common. People with resistant staph infections may require hospitalization to receive antibiotics through an IV or by injection.. As far as we know, however, bacteria do not develop resistance to the complex natural antibiotics in herbs. ...
