Determinación de la carga microbiana de los servicios higiénicos de la unidad educativa Huachi Grande

Abstract

Toilets are places where most people go, so they are contaminated spaces, either due to lack of care or inadequate cleaning and disinfection procedures, allowing the emergence of diseases or infections of any kind, affecting both children and older adults. The purpose of this research was to determine the microbial load in the toilets of the Huachi Grande Educational Unit, for which four specific points were taken into account: the external and internal toilet, the flushing flush and the faucet faucet. Samples taken from these points were collected after cleaning and before cleaning; consequently, E. coli, coliforms and mesophilic aerobes were counted on 3M Petrifilm plates. It was determined that the flushing flush and the faucet tap after cleaning are the points with the highest contamination with an average of E. coli of 8.9 UFC/𝑐𝑚2, coliforms of 21.7 UFC/𝑐𝑚2 and 70 UFC/𝑐𝑚2 of mesophilic aerobes were found in the flushing faucet, while the faucet tap had 1.48 UFC/𝑐𝑚2 of E. coli, 4.1 UFC/𝑐𝑚2 of coliforms and 16 UFC/𝑐𝑚2 of mesophilic aerobes. The following micro-organisms were identified using automated equipment: Kluyvera intermedia, Escherichia coli, Enterobacter cloacae complex, Serratia liquefaciens and Pantoea spp
