Fundamento

Recientes pero escasos informes de cepas de Staphylococcuss aureus resistentes a la meticilina (SARM) entre niños no expuestos a los factores de riesgos asociados con su adquisición, nos indujeron a investigar su circulación en la comunidad

Pacientes y Métodos

Durante los meses de septiembre y octubre de 1997 se tomaron exudados nasales y faríngeos a 358 niños menores de 5 años, atendidos en tres círculos infantiles del municipio Marianao de la Ciudad de La Habana, Cuba. Las cepas de S. aureus aisladas fueron caracterizadas por susceptibilidad a antimicrobianos utilizando el método de Kirby-Bauer. Se confirmó la resistencia a la meticilina a través del método “Oxacillin Salt-Agar Screening-Plate” recomendado por el Comité Nacional de Procedimientos Estándar del Laboratorio Clínico

Resultados

El 18,7% de los niños portaban cepas de S. aureus en el tracto respiratorio superior. En el 2,2% eran cepas de SARM. Los índices más altos de resistencia se revelaron para la eritromicina (50,7%) y tetraciclina (29,9%). Todas las cepas fueron susceptibles a la ciprofloxacina

Conclusiones

Nuestros resultados proporcionan evidencias sobre el aislamiento de cepas de SARM entre niños sanos atendidos en círculos infantiles, e indican la posibilidad de que éstas se establezcan y diseminen de forma acelerada en la comunidad

Background

Recent but scarce reports of methicillin-resistant Staphylococcus aureus strains (MRSA) among children without risk factos associated with its acquisition promted us to investigate its presence in the community

Patients and Methods

During the September and October months in 1997, nasal and pharyngeal swabs were obtained from 358 children aged less than five years who attended three day-care centers in the Marianao Area, La Habana City, Cuba. The isolated S. aureus strains were characterized for antimicrobial sensitivity using the Kirby-Bauer method. Methicillin resistance was confirmed by te ˝Oxacillin Salt-Agar Screening-Plate˝ method recommended by the National Committee for Clinical Laboratory Standards

Results

18.7% of children were carriers of S. aureus in the upper respiratory tract; 2.2% of children carried MRSA strains. The highest resistance levels corresponded to erythromycin (50.74%) and tetracycline (29.9%). All tested strains were sensitive to ciprofloxacin

Conclusions

Our results provide evidence on the recovery of MRSA strains among healthy children attending daycare centers and are suggestive of a rapid colonization and spread of these microorganisms in the community.
