摘要:
The present invention relates to a solid culture medium for the detection and/or discrimination, among glycopeptide-resistant enterococci, of the groups of species E. faecalis and/or E. faecium belonging to the groups of resistance to the VanA/VanB glycopeptides, and E. gallinarum/E. casseliflavus belonging to the group of resistance to the VanC glycopeptides, wherein said medium comprises, in a culture medium selective for enterococci, at least one chromogenic substrate for α-glucosidase and at least one activator of a coloured reaction, chosen from methyl-α-glucoside and glucosyl-α-glucoside, or polymers thereof.
摘要:
The invention concerns a method for detecting microorganisms present in a sample, which consists in inoculating a culture medium with said sample, said culture medium preferably containing chromogens releasing chromophores in the presence of target microorganisms or fluorogens, said culture medium being in a container with a coloured base, detection being facilitated by contrast between the coloured base and the isolated colonies.
摘要:
The invention concerns a culture medium for isolating enterococcus comprising violet crystal, and preferably gram-negative bacteria inhibitors and chromogens. The invention also concerns a method for detecting enterococcus using said medium.
摘要:
The present invention relates to a culture medium intended for the identification of Salmonella bacteria, comprising, in addition to a culture medium for Salmonella, as chromogenic agents, a combination of : a chromogenic compound linked to a C7-C10 fatty acid, and an appropriate detergent which promotes the liberation of the chromogenic compound. The present invention also relates to a process for detecting Salmonella.
摘要:
The invention describes a culture medium for the enumeration of E. coli which comprises, in addition to a culture medium for E. coli, a combination of a chromogenic compound derived from indolylglucuronic acid as a substrate of the GUS enzyme and a derivative of alkyl, alkenyl or aryl glucuronic acid, serving as a chromogenic agent. A method for the enumeration of E. coli is also disclosed.
摘要:
A method for revealing the presence or absence of a particular microorganism strain in a culture medium, wherein at least two strain enzyme substrate chromogens are added to the culture medium, said chromogens being selected so that the presence of said strain in the culture medium is revealed by a third colour.
摘要:
L'invention concerne des souches de E.Coli productrices de vitamine B12 transformées par un ADN hétérologue comportant tout ou partie de la région cobI et permettant l'expression de ladite région dans E.Coli . En particulier, la région cobI est la région de Salmonella typhimurium .
摘要:
The present invention relates to a culture medium for detecting pathogenic Yersinia enterocolitica bacteria, comprising at least one chromogenic agent which is a substrate of an acetyl-glucosaminidase, to a method of detection using such a medium and to the use of such a medium for the detection of pathogenic Yersinia enterocolitica bacteria.
