Quantitative determination of enterococci in water using an alternative chromogenic method. For this purpose, several microorganisms are used as indicators of fecal contamination. Among them are enterococci, which are considered to be good esculian, since they survive for a longer time in adverse natural conditions.

The samples were assayed in parallel with the two methodologies alternative and reference using the membrane filtration technique. The following parameters were determined to evaluate the performance of the methods: The first three parameters were estimated for both methods before and after confirmation by biochemical testing.

Results were analyzed statistically based on the bbilis criteria defined by ISO standards and It is also a simple, faster and economically feasible method. El cultivo puro de E. Los medios se prepararon de acuerdo a las instrucciones del fabricante. Los valores de pH y conductividad se muestran en la tabla 1. Se seleccionaron e identificaron 1 colonias diana y no diana procedentes de los medios alternativo y de referencia. Esos aislamientos fueron identificados como Aerococcus viridansStreptococcus spp.


El valor de kappa fue 0, Varios trabajos sugieren que Enterococcus y E. El procedimiento de referencia incluye una etapa presuntiva y una confirmativa, lo cual incrementa los costos de los controles de calidad del agua.
