Antibiotic resistance of coagulase-negative staphylococci and micrococci.
Five hundred and seventy strains of Gram-positive, catalase-positive, coagulasenegative cocci from various sources were classified on the basis of their ability to grow anaerobically and to ferment mannitol. Five groups were distinguished. The frequency of strains classified in the five groups varied with the source. Only 26% of the strains were sensitive to all the nine antibiotics used in the...
متن کاملRole of coagulase-negative staphylococci and micrococci in ocular disease.
Forty-nine strains of coagulase-negative staphylococci and 26 strains of micrococci isolated from human eyes were classified by the Baird-Parker system of 1966. The staphylococci belonged to subgroups II, III, IV, and V with one strain each in subgroups III and IV. However, when biotyped by Baird-Parker's system of 1974, less than 50% (23/49) of strains were typable and they belonged to biotype...
متن کاملCoagulase-negative staphylococci and micrococci in urinary tract infections.
One hundred catalase-positive, coagulase-negative, Gram-positive cocci isolated in significant numbers from the urine of patients with urinary tract infections, provisionally subdivided by their sensitivity to nonoviocin, were classified according to a slightly model version of Baird-Parker's schemes (1965 and 1972). It appeared that strains of Micrococcus were nearly all of sub-group 3, and th...
متن کاملA serological method for distinguishing coagulase-negative staphylococci from micrococci.
Absorbed antisera prepared against heat-killed suspensions of a coagulase-negative staphylococcus and of a micrococcus were used in a slide-agglutination test. A collection of 176 coagulase-negative aerobic cocci, from which Staphylococcus aureus had been excluded, was classified into staphylococci and micrococci by means of the test for anaerobic utilization of glucose. Of 113 staphylococci, 9...
متن کاملAntibiotic susceptibility pattern and biofilm formation in coagulase negative staphylococci.
Introduction Coagulase negative staphylococci (CoNS) are commensals of non-sterile sites in humans and become pathogenic mostly when the host is immunocompromised by prior diseases or invasive surgical or related procedures [1]. Slime or biofilm production by CoNS has been identified as an important factor in the pathogenesis of infections as bacteria organized in biofilms are protected from th...
