Coagulase-negative strains of Staphylococcus pyogenes.
The isolation of two coagulase-negative strains of Staphylococcus pyogenes is reported, and their biochemical characteristics are given. The reliability of coagulase tests alone in the identification of Staph. pyogenes is discussed, and the deoxyribonuclease test is recommended as a useful confirmatory test.
متن کاملStaphylococcus pettenkoferi sp. nov., a novel coagulase-negative staphylococcal species isolated from human clinical specimens.
Five coagulase-negative, novobiocin-susceptible staphylococcal strains were isolated from human blood cultures in different German and Belgian medical facilities. A novel species, 'Staphylococcus pettenkoferi' was proposed recently to accommodate two of these strains (B3117(T) and A6664), although the name was not validly published. All five strains belonged to the genus Staphylococcus because ...
متن کاملStaphylococcus chromogenes, a Coagulase-Negative Staphylococcus Species That Can Clot Plasma.
Staphylococcus chromogenes is one of the main coagulase-negative staphylococci isolated from mastitis of dairy cows. We describe S. chromogenes isolates that can clot plasma. Since the main pathogen causing mastitis is coagulase-positive Staphylococcus aureus, the coagulase-positive phenotype of S. chromogenes described here can easily lead to misidentification.

The crescents were accompanied by foci of fibrinoid necrosis with endocapillary and extracapillary fibrin. Tubular atrophy and interstitial fibrosis were absent. Interstitial inflammation was present, focal and accompanied by tubular degenerative changes. There was evidence of necrotizing vasculitis. IF revealed granular, segmental to global glomerular capillary wall positivity for IgG, kappa a...
متن کاملEvaluation of trehalose-mannitol broth for differentiation of Staphylococcus epidermidis from other coagulase-negative staphylococcal species.
Trehalose-mannitol agar and various broth formulations thereof were evaluated for the differentiation of Staphylococcus epidermidis from other common coagulase-negative staphylococcal species isolated from human blood cultures. While this differentiation was accurately made on trehalose-mannitol agar in 18 h, modification of the medium to a broth formulation containing 2% each trehalose and man...
