dc.description.abstractLa colonización nasal de Staphylococcus aureus en el personal de salud y la contaminación de superficies hospitalarias puede preceder a la infección nosocomial. El objetivo de este estudio fue caracterizar los aislamientos de S. aureus que se encuentran en el ambiente hospitalario y en el personal de salud de un hospital de Cali. Material y Métodos: Se empleó un total de 164 muestras (86 del personal de salud y 78 de las salas del hospital). Se realizó antibiograma y se amplificó por PCR los genes mecA y agr. El S. aureus resistente a meticilina asociado al hospital (SARM-AH) o el SARM asociado a la comunidad (SARM-AC) se estableció mediante el análisis de estos genes. Resultados: El S. aureus registró un 21,3% de prevalencia, se detectó en el personal de salud (9,1%) y en el ambiente hospitalario (12,2%). El S. aureus en la unidad de cuidados intensivos fue significativo, con un riesgo mayor de tres (6,1%; OR=3,143, min=1,086, max=9,099; P=0,031). Se identificaron tres perfiles de resistencia (I, II y III), el ambiente hospitalario presentó mayor riesgo de presentar aislamientos con perfil I (20%; OR= 3,500; IC 95% min= 0,050; max = 16,430; p= 0,147). Sin embargo, los aislamientos con el perfil III con multirresistencia a los antibióticos, fueron los más prevalentes en el personal de salud (25,7%) y el ambiente hospitalario (20%).Los aislamientos SARM se encontraron colonizando al 11,4% del personal de salud y en el 17,1% de las superficies del ambiente hospitalario. Todos los aislamientos SARM fueron SCCmec tipo II, compatible con un origen hospitalario. Según el análisis del locus agr, se identificaron tres grupos agr, el 51,4% de los aislamientos pertenecen al grupo agr 1, el 22,8% al agr 2 y el 25,7% al agr 3. Conclusión: Se evidenció la presencia de SARM en el personal y en diferentes salas del hospital. Esta condición podría ser un factor de riesgo para desarrollar infecciones adquiridas en el hospital.spa
dc.description.abstractNasal colonization of Staphylococcus aureus in health personnel and contamination of hospital surfaces may precede nosocomial infection. This study aimed to characterize the isolates of Staphylococcus aureus found in hospital environments and healthcare staff in a hospital in the city of Cali. Materials and Methods: A total of 164 samples (86 from the healthcare staff and 78 from the hospital wards) were used in this study. The characterization was based on the antibiogram analysis and PCR amplification of the mecA and agr genes. The methicillin-resistant S. aureus associated with the hospital (MRSA-AH) or the MRSA associated with the community (MRSA-AC) were established by analyzing these genes. Results: S. aureus recorded 21.3% prevalence, and it was detected in healthcare staff (9.1%) and the hospital environment (12.2%). S. aureus found in the intensive care unit was significant with higher risk than 3 (6.1%; OR = 3.143, min = 1.086, max = 9.099; p = 0.031). Three resistance profiles were identified (I, II, and III), and the hospital environment presented a higher risk of having isolates with resistance profile I (20%; OR = 3.500; CI95% min = 0.050, max = 16.430; p = 0.147). However, isolates classified in profile III with multi-resistance to antibiotics were most prevalent in the healthcare staff (25.7%) and the hospital environment (20%). The MRSA isolates were found colonizing 11.4% health care staff and 17.1% on surfaces of the hospital environment. All MRSA isolates were SCC mec type II, compatible with hospital origin. According to the analysis of agr locus, it was possible to identify three agr groups; 51.4% belonging to agr group 1, 22.8% to agr 2, and 25.7% to agr 3. Conclusion: This study evidenced the presence of MRSA in the healthcare staff and different wards of the hospital. This condition could be a risk factor for developing infections acquired in the hospital.eng
