Abstract

Un procedimiento mejorado para determinar la presencia o la ausencia de un contaminante bacteriano en una muestra con material biológico, contaminante bacteriano que se selecciona del grupo que consiste en Mycoplasma hyorhinis, Mycoplasma arginini, Mycoplasma pneumoniae, Mycoplasma 5 fermentans, Mycoplasma orale, Mycoplasma pirium, Acholeplasma laidlawii y Spiroplasma mirium, procedimiento que comprende las etapas de (a) procesar la muestra y purificar los ácidos nucleicos de la muestra procesada; seguido de (b) formar una composición para una reacción de amplificación basada en PCR (mezcla de reacción), composición que incluye - un primer cebador de acuerdo con la SEQ ID NO:1, - un segundo cebador de acuerdo con la SEQ ID NO:2 y - los ácidos nucleicos purificados de la etapa (a) o una fracción medida de los mismos como molde; seguido de (c) realizar una reacción en cadena de la polimerasa (PCR) con la composición de la etapa (b); seguido de (d) detectar la presencia o la ausencia de una secuencia objetivo amplificada, en el que la presencia de dicha secuencia objetivo amplificada indica la presencia del contaminante bacteriano en la muestra y la ausencia de dicha secuencia objetivo amplificada indica la ausencia del contaminante bacteriano en la muestra; mejora caracterizada por que en relación con el volumen de la muestra, se añade una cantidad predeterminada de ADN de células CHO a (i) la muestra o (ii) la muestra procesada de la etapa (a), o (iii) a los ácidos nucleicos obtenidos en la etapa (a), o (iv) a la composición de la etapa (b), de modo que el ADN de células CHO añadido reduce la amplificación inespecífica de la etapa (d).
