[Carrier status of Staphylococcus aureus among students of different courses]

Staphylococcus aureus is a frequent pathogen of nosocomial infections. The main part in the spread of these microorganisms take symptomless carriers. The aim the research was defining the carrierstate of S. aureus among students of Medical Academy and University. The investigation showed a greater carrierstate in the group of Medical students (33%) than in the group of University students. Strains isolated from the Medical students were more differentiated in biochemical tests and they were more drug-resistant mainly to Augmentin (51.5% resistant strains) and doxycycline (24% resistant strains). A great percentage of ampicillin-resistant strains (94%) was found among the strains isolated from both groups. Results of the research showed greater carrierstate among people who had direct contact with patients and infectious materials and proved a wide range of drug-resistance among hospital strains. Carriers of S. aureus among medical personnel could influence the spreading of nosocomial infections mainly on ICU and Newborn Wards.
