Abstract

LA PRESENCIA O AUSENCIA DE UN MICROBIO OBJETIVO PREDETERMINADO EN UNA MUESTRA SE DETERMINA POR ADICION DE UN MEDIO DE ENSAYO A LA MUESTRA, O VICEVERSA. EL MEDIO DE ENSAYO PROPORCIONA UN MEDIO DE CRECIMIENTO SELECTIVO PARA EL MICROBIO BLANCO O DIANA, E INCLUYE UN NUTRIENTE ESPECIFICO QUE SOLO PUEDE METABOLIZAR EL MICROBIO DIANA. ESTE NUTRIENTE ESPECIFICO SE MODIFICA UNIENDOLE UNA MITAD ALTERADORA DE LA MUESTRA, CON LO QUE EL NUTRIENTE SE CONVIERTE EN INDICADOR NUTRIENTE. LA MITAD ALTERADORA DE LA MUESTRA SE ACTIVA PARA ALTERAR LA MUESTRA SOLO SI EL NUTRIENTE ESPECIFICO SE METABOLIZA POR EL MICROBIO DIANA. LA MITAD ALTERADORA DE LA MUESTRA PUEDE SER UN MATERIAL QUE CAMBIA EL COLOR DE LA MUESTRA (VISIBLE O NO VISIBLE) O CAMBIA UNA CARACTERISTICA ELECTRICA DE LA MUESTRA, O ALTERA ALGUNA OTRA CARACTERISTICA DETECTABLE DE LA MUESTRA. EL MEDIO DE ENSAYO NO TIENE QUE MANTENERSE ESTERIL, Y EL PROCEDIMIENTO DE ENSAYO NO TIENE QUE LLEVARSE A CABO EN AMBIENTE ESTERIL.
