A total of 299 isolates of gram-positive, catalase-positive, coagulase-negative cocci were isolated from a variety of specimens collected from patients at a large university hospital, and 281 (94%) were identified as staphylococci by established methods. Using the scheme of Kloos and Schleifer, we determined the species of the coagulase-negative staphylococci. Staphylococcus epidermidis was the...

Coagulase-negative staphylococci produce an exocellular glycolipid antigen which has potential as a serological marker of infection in bone. The value of this newly detected antigen was investigated by enzyme-linked immunosorbent assay (ELISA) in 15 patients with culture-proven infection of prostheses caused by Gram-positive bacteria. The antigen was purified by gel-permeation chromatography fr...

technique, and 9 of 20 when an anaerobic jar was used). Thus, anaerobic fermentation of mannitol seems to be too exacting a criterion, but all methods using glucose fermentation classified the 20 coagulase-positive strains as staphylococci. The classification of other staphylococci into S. saprophyticus and S. lactis on their ability to produce acetoin from glucose (Shaw et al.) was not support...

The coagulae-positive staphylococci comprise a very homogeneous, readily identifiable species (Evans and Niven, 1950; Shaw et al., 1951) that includes all of the proven pathogenic and enterotoxin-producing strains of staphylococci. As a result of the clinical and public health significance of these organisms, a selective medium for their isolation and enumeration would have considerable value. ...

PURPOSE The aim of this study was to compare the resistance patterns of bacteria in vitreous fluid from patients undergoing vitrectomy for diagnostic reasons, with bacteria of other nosocomial infections. METHODS Vitreous fluid samples (n=144) were obtained from 133 patients undergoing vitrectomy for endophthalmitis, and 11 for uveitis as suspected endophthalmitis. They were Gram stained and ...

BACKGROUND Bacteria are the major contributor of ocular infections worldwide. Ocular infections, if left untreated, can damage the structures of the eye with possible blindness and visual impairments. This work was aimed to review the bacterial profile of ocular infections. METHODS Literature search was made in different electronic databases; the review was systematically made to get concrete...
