We report a case of a 49-year-old patient who developed poststaphylococcal coagulase negative reactive arthritis. The woman presented with constitutional symptoms, arthritis, urinary infection and conjunctivitis. The blood culture was positive for the staphylococcal coagulase negative infection. Erythrocyte sedimentation rate and C-reactive protein were elevated, whereas the rheumatoid factor w...

The sera of several animals were examined for suitability in coagulase testing. The assay for coagulase-reacting factor (CRF) activities of the whole sera indicated the following relative concentrations of CRF: human > pig > rabbit > horse > bovine, chicken, and lamb. Human, pig, and rabbit sera had adequate amounts of CRF for coagulase testing. The plasmin activities of the different sera, arr...

A total of 504 clinical isolates of the family Micrococcaceae were tested for coagulase, deoxyribonuclease, clumping factor, and phosphatase to determine whether there is a correlation between the results of these tests and the pathogenicity of staphylococci. In the tests for coagulase production, it was found that either human or rabbit plasma could be used with broth cultures, whereas rabbit ...

During 1984, 35 patients undergoing continuous peritoneal dialysis experienced 77 cases of peritonitis with 55 cases (71.4%) related to staphylococci. Coagulase-negative staphylococci were isolated in 41 cases, while Staphylococcus aureus was found in 14. A coexisting tunnel infection was more often associated with S. aureus (7/14) than with coagulase-negative staphylococci (2/41) (P less than ...

We report a case of a haemodialysis patient that presented a catheter-related bacteraemia caused by a Coagulase negative Staphylococcus. With the utilization of molecular biology techniques the bacterial isolate recovered from catheter was surprisingly identified as S. hominis by sequencing of the 16S ribosomal gene. The S. hominis isolate, which is not often associated with infections in dialy...

Staphylococcus intermedius is a zoonotic organism that can be associated with human disease. We report two separate cases of S. intermedius infection in which a false-positive rapid penicillin binding protein 2a latex test in conjunction with the phenotypic properties of beta-hemolysis and coagulase positivity allowed the clinical isolates to masquerade as methicillin-resistant Staphylococcus a...

A prospective study was conducted to determine the prevalence of aminoglycoside-resistant Staphylococcus aureus and coagulase-negative staphylococci before and after the introduction of amikacin as the sole aminoglycoside used in our burn unit, adult intensive care unit, and neonatal intensive care unit. Pharyngeal or endotracheal cultures, as well as superficial surveillance cultures, were col...

We developed, validated, and implemented real-time polymerase chain reaction (PCR) detection of the femA gene for Staphylococcus aureus and the mecA gene for methicillin resistance directly from BACTEC (Becton Dickinson, Sparks, MD) blood culture bottles showing gram-positive cocci in clusters. For the 332 positive blood cultures tested, the assay had 100% sensitivity and specificity for identi...

Objectives: Vancomycin use for neonatal coagulase-negative staphylococci (CoNS) sepsis is based on a high CoNS carriage rate of mecA, encoding penicillin-binding protein (PBP)-2a, with low affinity for, and associated with resistance to, b-lactam antibiotics. The relationship between mecA gene carriage, phenotypic expression of the gene by PBP-2a production and in vitro resistance to the b-lact...

Detection of multidrug-resistant Staphylococcus aureus and coagulase-negative staphylococci in cow milk hands farmers East Java, Indonesia. Biodiversitas 24: 658-664. Cow is a nutrient-dense food containing various nutrients, i.e., carbohydrates, fat, pro...
