[Sensitivity of 858 strains of staphylococci to 27 antibiotics]. 1986

J P Gayral, and M T Albertini, and E Gallice, and M Olléon

Susceptibility to 27 antimicrobial agents of 858 strains of staphylococci was determined. Tested strains belonged to the following species: S. epidermidis, S. saprophyticus, S. haemolyticus, S. hominis, S. simulans, S. warneri, S. cohnii, S. xylosus and S. intermedius. The antibiotics were: penicillin G, amoxycillin, augmentin, oxacillin, streptomycin, kanamycin, tobramycin, dibekacin, amikacin, gentamicin, sisomycin, netilmicin, doxycycline, minocycline, chloramphenicol, erythromycin, josamycin, clindamycin, pristinamycin, rifampin, fusidic acid, fosfomycin, trimethoprim, sulfamethoxazole, cotrimoxazole, and vancomycin. The ATB system was used, with the criteria for categorization recommended by the Antibiotic Sensitivity Testing Committee. Penicillin-resistance, that was found in all species, was high for hospital-acquired strains (67 to 75%) but also for some other strains (32% for S. simulans). Oxacillin-resistance varied across species (0% for the least prevalent hospital strains, 6% for S. epidermidis and 28% for S. haemolyticus). All strains were susceptible to vancomycin. For some drugs, resistance was a characteristic of the species: resistance to fosfomycin was often found for S. saprophyticus, S. haemolyticus, S. warneri, S. cohnii, and S. capitis; resistance to trimethoprim was common for S. simulans, and S. haemolyticus. S. haemolyticus was the most resistant species, a fact that justifies routine identification of this pathogen in clinical specimens.

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.

D013210	Staphylococcus	A genus of gram-positive, facultatively anaerobic, coccoid bacteria. Its organisms occur singly, in pairs, and in tetrads and characteristically divide in more than one plane to form irregular clusters. Natural populations of Staphylococcus are found on the skin and mucous membranes of warm-blooded animals. Some species are opportunistic pathogens of humans and animals.
