摘要
introduction: the genus staphylococcus is responsible for a great number of bacterial infections in human, mainly in hospital environment. objectives: in view of these considerations and the importance of nursing care and nosocomial infection control, this study verified the rate of s. aureus and coagulase-negative staphylococci (cns) carriers resistant to oxacillin in nursing students during their university course. materials and methods: nasal samples were collected from nursing students at botucatu school of medicine - unesp. results: from 109 isolated samples of staphylococcus, 30 samples (27.5%) were staphylococcus aureus and 79 samples (72.5%) were cns. from 79 identified cns samples, 63 (79.7%) were s. epidermidis, nine (11.4%) s. warneri, three (3.8%) s. haemolyticus, two (2.5%) s. capitis, one (1.3%) s. simulans and one (1.3%) s. lugdunensis. the antibiotic susceptibility test showed 100% sensibility to the drugs in s. aureus samples and among 79 cns samples, 10 (12,6%) were resistant to oxacillin. the pcr technique demonstrated negative result for meca gene in s. aureus samples and 11 positive samples among cns species. discussion: there was no relation between the rate of s. aureus carriers and nosocomial involvement during the course. the results also showed a higher incidence of resistance in cns samples, which is seemingly reported in the scientific literature.
