RESUMEN

Objetivo:

analizar microrganismos presentes en las superficies inertes, que representen un riesgo para la salud de los estudiantes.

Métodos:

se realizó un estudio observacional, exploratorio y transversal realizado en el periodo febrero- julio de 2012. Se efectuó en un muestreo aleatorio utilizando el método del hisopo y se obtuvieron 72 muestras. Las unidades de análisis fueron mesas, microscopios y charolas por considerarse superficies de mayor contacto con alumnos.

Resultados:

se encontraron hongos en el 100 por ciento de los cultivos realizados y bacterias en el 66 por ciento. De estas, el 25 por ciento (12) correspondieron a bacterias de flora normal, el 62,5 por ciento (30) a bacterias oportunistas y 12,5 por ciento (6) a bacterias patógenas.

Conclusión:

las mesas y los microscopios de los laboratorios de enseñanza se encuentran contaminados por hongos y bacterias como Salmonella paratyphi A y Salmonella sp que constituyen un riesgo de infección para los estudiantes que realizan prácticas educativas(AU)
ABSTRACT

Objective:

analyze microorganisms present on inert surfaces which represent a health hazard for students.

Methods:

an observational cross-sectional exploratory study was conducted from February to July 2012. Random sampling was performed using the swab method. Seventy-two samples were obtained. The study surfaces were tables, microscopes and trays, i.e. the surfaces most commonly touched by students.

Results:

fungi were found in 100 percent of the cultures. Bacteria were found in 66%. Of the latter, 25 percent (12) were normal flora bacteria, 62.5 percent (30) were opportunistic, and 12.5 (6) were pathogenic.

Conclusion:

tables and microscopes in teaching laboratories were contaminated with fungi and bacteria such as Salmonella paratyphi A and Salmonella sp., which constitutes an infection hazard for students doing laboratory practice(AU)
