| dc.description | Performance of Petrifilm VRB and SM plates to enumerate different types of bacterial populations was evaluated. A total of 100 Petrifilms and 100 regular Petri plates were tested with each of 3 different bacterial populations in 4 experiments. The Petrifilm system was superior to the conventional pour plate methods, or at least not statistically different, in enumerating Escherichia coli (coliform) and a mixture of E. coli, Staphylococcus aureus and Serratia marcescens (total aerobic plate count). The Petrifilm method was superior to conventional plate counts in enumerating Pseudomonas aeruginosa (psychrotrophic plate count), when both incubations were at 21°-22° C for 96 h. If sustained in further experimentation, this last observation would mean that the Petrifilm SM system could be successfully used to detect bacterial populations in addition to those for which the system was originally intended. | en-US |
| dc.description | Se evaluó el comportamiento de las placas "Petrifilm VRB" (detección de coliformes) y SM (detección de conteo total) para enumerar diferentes tipos de bacterias. Se llevaron a cabo 4 experimentos comparativos, en los que se utilizaron un total de 100 placas "Petrifilm" y 100 placas Petri corrientes en cada una de 3 muestras de diferentes bacterias. El sistema "Petrifilm" demostró ser superior o, al menos, no estadísticamente diferente al corriente al enumerar Escherichia coli (coliforme) y una mezcla de E. coli, Stephylococcus aureus y Serratia marcescens (conteo total aeróbico). Cuando se incubaron a entre 21° y 22° C. por 96 horas, el sistema "Petrifilm" demostró ser mejor para la enumeración de Pseudomonas aeruginosa (conteo psicrotrófico). Si esto se repite en subsiguiente experimentación, significaría que el sistema "Petrifilm SM" podría usarse para detector y enumerar la presencia de bacterias distintas a las que originalmente se pretendía cuantificar cuando se diseño el sistema. | es-ES |
