MICROBIOLOGIC STUDY OF THE LAGOON “LA ESCONDIDA” IN REYNOSA CITY, MEXCIO, IN FOUR SEASONS OF THE YEAR(Abstract)

摘要

The microbiological quality of water from “La Escondida” lagoon in Reynosa, Tamaulipas, was evaluated. Nine water samples were used to obtain a single composed sample. The presence of aerobic mesophilic, total and fecal coliforms, Salmonella and Shigella, fungi, yeasts and parasites was determined in the composed water sample. There was a growth with different degree of density, with potentially pathogenic metabolic activities, as alpha and beta hemolysis; the growth of enterobacteria and coliforms, besides the presence of parasite eggs, which demonstrate that the water quality of this water body is poor, constituting a health risk. The changes in the weather did not have a significant impact in the microbial population profiles.
