Popis: The aim of this research was to evaluate the antimicrobial susceptibility of Staphylococcus spp. strains isolated in nostrils and hands from 19 nursing professionals, associated to the neonatology unit of the University Hospital “Antonio Patricio de Alcalá”, Cumana, Sucre state, during the period July - August 2009. The bacterial identification was carried out by conventional microbiological methods. To determine the antimicrobial susceptibility, the disk diffusion method was used, according to the Clinical Laboratory and Standards Institute guideline. Results showed that 21.05% of individual samples were of Staphylococcus aureus and 78.95% were coagulase negative Staphylococcus (CNS). Most isolations were obtained from the nostrils (50.00%). Regarding the antimicrobial susceptibility, strains of S. aureus from the nostrils were resistant to Oxacilline 66.67% and 33.33% to Ciprofloxacin and Erythromycin. CNS were resistant to Erythromycin (90.00%), Clindamycin (50.00%), Ciprofloxacin (40.00%) and Oxacilline (30.00%). The S. aureus strains isolated from hands resulted resistant to all the studied antibiotics (50.00%), and in the CNS isolated from hands, most resistance was related to Erythromycin (91.67%), while Clindamycin, Oxacilline and Ciprofloxacin showed resistance percentages of 58.33%, 50.00% and 41.67%, respectively. This study reveals the presence of methicillin-resistant strains of Staphylococcus spp. among the nursing personnel of the neonatal unit, and the colonization of these bacteria increases the likelihood of transmission of strains from staff to patient, and among them and the community.
