Title (EN) NEGATIVE CONTROL MEDIA FOR MICROBIOLOGIC BIOCHEMICAL TESTS
(FR) MILIEU DE CONTROLE NEGATIF POUR ANALYSES MICROBIOLOGIQUES BIOCHIMIQUES
Abstract: front page image
(EN)A microorganism identification test container comprises a tray member (2) provided with a plurality of wells (18, 20, 22). Some of the wells (20) are microorganism identification test wells (20) having biochemical test media which permits growth of microorganisms with the generation of a volatile color-forming compound. Some of the wells are negative control wells (18) including an inhibit or which prevents color formation in the negative control wells caused by the volatile color-forming compound generated in the test wells. Preferably a series of biochemical test media is adjacent to the corresponding negative control medium. Comparison between the negative control wells (18) and the test wells (20) after inoculation and incubation of the microorganism, indicates the presence of a particular microorganism. Since many of the biochemical test media produce only subtle changes in response to microorganism activity, the appearance of the negative control must remain essentially unchanged or subtle changes in the biochemical test wells will not be perceived.
(FR)Un conteneur d"analyse d"identification d"un micro-organisme comprend un organe sous forme de plateau (2) pourvu d"une pluralite de puits (18, 20, 22). Certains de ces puits (20) sont des puits d"analyse d"identification de micro-organismes (20) ayant un milieu d"analyse biochimique qui permet la croissance de micro-organismes avec la generation d"un compose volatil de formation de couleurs. Certains de ces puits sont des puits de controle negatif (18) comprenant un inhibiteur qui empeche la formation de la couleur dans les puits de controle negatif provoquee par les composes volatils de formation de couleurs generes dans les puits d"analyses. De preference une serie de milieux d"analyse biochimique est adjacente au milieu correspondant de controle negatif. La comparaison entre les puits de controle negatif (18) et le puit d"analyse (20) apres inoculation et incubation du micro-organisme, indique la presence d"un micro-organisme particulier. Etant donne que de nombreux milieux d"analyse biochimique ne produisent que des changements tres subtils en reponse a l"activite du micro-organisme, l"aspect du controle negatif doit rester essentiellement inchange ou des changements subtils dans les puits d"analyses biochimiques ne seront pas percus.
