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.

Skalka B.: Bacteriocin Activity of Staphylococcus aureus, Staphylococcus intermedius and Coagulase-n.egative Staphylococcal Strains. Acta vet. Brno, 55, 1986: 65-72. A total of 567 staphylococcal strains was examined for bacteriocin activity. It contained 367 S. aureus strains, 114 S. intermedius strains, and 86 coagulasenegative staphylococci belonging to ten species. The deferred method was e...

Coagulase-negative staphylococcus—oftentimes a virulent masquerader

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...

Immunological relationship between delta-hemolysins of Staphylococcus aureus and coagulase-negative strains of staphylococci.

Delta-hemolysin of coagulase-negative staphylococcal strains was immunologically identical to delta-hemolysin of Staphylococcus aureus (Newman) but distinct from delta-hemolysin from a canine strain of S. aureus.

Coagulase-negative strains of staphylococcus possessing antigen 51 as agents of urinary infection.

A group of strains of Staphylococcus albus is described which produced neither coagulase nor haemolysin, was slightly sensitive or resistant to novobiocin, and sensitive to all other antibiotics, to sulphonamides, and to nitrofurantoin. The agglutinating antigen 51 was isolated from all strains from patients with urinary infections and abundant pyuria. In more than 40 cases studied it was not p...
