A majority of cochlear implant infections are caused by Staphylococcus aureus or Pseudomonas aeruginosa. Reported here is a pediatric patient with a cochlear implant infection caused by methicillin-resistant Staphylococcus lugdunensis, a coagulase-negative Staphylococcus that has only recently been determined to be clinically relevant (1988). Unlike other coagulase-negative Staphylococcus, it i...

Mupirocin MICs and mupA presence were determined in 108 staphylococci causing prosthetic joint infection. Zero of 35 isolates (0%) of methicillin-susceptible Staphylococcus aureus, 4/15 (27%) methicillin-resistant S. aureus isolates, 3/16 (19%) methicillin-susceptible coagulase-negative staphylococci, and 11/42 (26%) methicillin-resistant coagulase-negative staphylococci were mupirocin resistan...

Candida coagulase production was assessed by the classical tube test. All Candida krusei strains were coagulase negative, but most C. albicans and C. tropicalis strains can produce coagulase. Some strains agglutinated the Pastorex Staph-Plus reagent, probably because of antigen similarities to coagulase produced by Staphylococcus aureus that may cause mistakes in clinical laboratories.

A total of 353 coagulase-negative staphylococcus (CNS) isolates from infected bovine mammary glands were tested for cytolysin production by using the synergistic hemolysin assay (SHA). Overall, 34.6% of CNS isolates were SHA positive. Human-associated, coagulase-negative staphylococcal species contained the greatest number of SHA-positive strains. Milk leukocyte levels expressed as somatic cell...

*Corresponding Author: [email protected] Abstract The aim of the study was to screening for coagulase positive methicillin resistant Staphylococcus aureus (MRSA) in healthcare workers and prevalence of nasal colonization with Staphylococcus aureus. We included 84 healthcare workers’ samples (nasal swabs) in the study. Different biochemical tests were done to isolate Staphylococcus aureus...
