Title
(EN) CULTURE MEDIUM AND DEVICE FOR DETECTION AND ENUMERATION OF ENTEROBACTERIACEAE
(FR) MILIEU DE CULTURE ET DISPOSITIF POUR LA DETECTION ET LE DENOMBREMENT D'ENTEROBACTERIACEAE
Abstract
(EN)
This invention generally relates to products and processes used to determine the presence of $i(Enterobacteriaceae) in a sample and particularly relates to a bacterial culture medium which may be used in products and processes to allow early detection and enumeration of $i(Enterobacteriaceae) in a sample. The bacterial culture medium which facilitates the early detection and enumeration of $i(Enterobacteriaceae) contains a selected amount of glucose, pH indicator and buffer which prevent diffusion of colored indicator zones associated with growing bacteria in the medium.
(FR)
Cette invention se rapporte d'une façon générale à des produits et à des procédés qu'on utilise pour déterminer la présence d'$i(Enterobacteriaceae) dans un échantillon et, en particulier, à un milieu de culture bactérien qui peut être utilisé dans des produits et des procédés destinés à permettre une détection et un dénombrement rapides d'$i(Enterobacteriaceae) dans un échantillon. Ce milieu de culture bactérien, qui facilite la détection et le dénombrement rapides d'$i(Enteriobacteriaceae), contient une quantité sélectionnée de glucose, d'un indicateur de pH et d'un tampon, qui empêchent la diffusion des zones indicatrices colorées associées aux bactéries cultivées dans ledit milieu.
