PORTADORES ASINTOMÁTICOS DE Staphylococcus aureus EN TRABAJADORES DEL HOSPITAL REGIONAL DE ICA, PERÚ 2011

Abstract

Objective: To determinate the prevalence of asymptomatic carriers and antimicrobial susceptibility of Staphylococcus aureus in workers at Ica Regional Hospital. Material and Methods: A descriptive-transversal study realized in November 2011. A simple aleatory sampling without repositioning, a total of131 workers participated in the study. Dates were collected using a file and the samples by cottons sawbs, obtaining 262 nasal and hand strains. The isolation, identification and susceptibility testing were made using the criteria of Clinical and Laboratory Standars Institute(CLSI).Data were processed in the SPSS version 18,doing univariate analysis and statistical significance tests. Results:The prevalence ofasymptomaticcarrierswas12.98%,in which 5.3% is the rate of nasal carriage and 10.7% in hands. All isolates were susceptible to: methicillin, cefaclor, ceftazidime, vancomycin and rifampin.Onlya few nasal isolates were resistant (7.1%) to: oxacillin, dicloxacilin, clarithromycin and chloramphenicol. Conclusion:The prevalence of asymptomatic carriers was low. It was showed a lower carrier frequency when workers used protective measures(p>0.05).The antimicrobial resistance was low, too. There must be a case-control study to identify protective factors.
