ESPINOSA GONZALEZ, Cindy Tatiana et al. Nasal carriers of Staphylococcus aureus in the personnel that works in a Hospital of Santander. Rev. Univ. Ind. Santander. Salud [online]. 2011, vol.43, n.2, pp.111-117. ISSN 0121-0807.

Introduction: Nosocomial infections are a public health problem worldwide, its spread start from health personnel carrier of pathogenic bacteria, it has been the focus of a large number of research to improve the quality of life of the patients. Objective: To determine the frequency of nasal carriers of Staphylococcus aureus in the personnel that works in intensive care units (adults ICU and pediatric ICU), pediatric infectology and lactary in a Hospital in Santander. Methodology: Nasal samples from 87 workers from of the Hospital were studied. Isolated strains were identified by the corresponding biochemical tests and subsequently determined their susceptibility profiles to different antibiotics and test D for S. aureus. Results: The frequency of nasal carriers of pathogenic bacteria was 41.4%; it was found that S. aureus was the most isolated pathogenic microorganism, with a frequency of (72%). The percentage of meticilin resistant S. aureus (MRSA) was 11.6% , Enterobacter aerogenes (6%), Proteus mirabilis (2.3%); Haemophylus influenzae (1.1%); Citrobacter koseri (1.1%) and Providencia rettgeri (1.1%). Conclusion: S. aureus is the most frequently isolated agent in health personnel's nasal nostrils and the presence of MRSA is worrying, additionally, it presents characteristic of resistance to antibiotics, making harder its treatment. This fact evidences the necessity to act with a preventive character, in which the control of carriers is critical and it should be associated with biosecurity measures to establish effective barriers to reduce the dissemination of the microorganism and occurrence of nosocomial infections.
