摘要:
The invention concerns a novel chromogenic medium for isolating Staphylococcus aureus, characterised in that it comprises in a culture medium of Staphylococcus aureus at least one of the following two chromogenic agents: 5-bromo 6-chloro 3-indoxyl phosphate and 5-bromo 4-chloro 3-indoxyl glucoside and it further contains deferoxamine.
摘要:
The invention concerns a culture medium for isolating Vibrio bacteria, characterised in that it comprises, in a Vibrio culture medium, at least a chromogenic agent selected among the beta -glucosidase substrates and the beta -galactosidase substrates.
摘要:
The invention concerns a culture medium for isolating Vibrio bacteria, characterised in that it comprises, in a Vibrio culture medium, at least a chromogenic agent selected among the β-glucosidase substrates and the β-galactosidase substrates.
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:
A method for revealing the presence or absence of a particular microorganism strain in a medium, wherein at least one strain enzyme substrate chromogen and at least one compound selected from a high-concentration carbohydrate are added to the culture medium so that a derived colour differing from the basic colour of the chromophore is obtained once the chromogen has been hydrolysed.
摘要:
La présente invention concerne un milieu d'isolement pour l'identification de la bactérie Salmonella , caractérisé en ce qu'à un support de culture contenant des peptones, on ajoute un polyol métabolisable par Salmonella et un indicateur de pH réagissant à l'acidification. La présente invention se rapporte en outre à un procédé d'identification de la bactérie Salmonella à partir dudit milieu.
摘要:
The invention concerns a medium for detecting, identifying and differentiating a microorganism strain in a liquid medium by contacting said liquid sample with a combination of chromogens substrates of enzymes expressed or not by the strain to be detected, the final coloration of the mixture being detectable in the wavelengths of the visible light.
摘要:
The invention relates to a novel solid medium for detecting meticillin-resistant micro-organisms, containing an antibiotic selected from the cephalosporin group, particularly second and third generation, and a chromogenic agent bearing a chromophore which is released after hydrolysis with an active enzyme in said micro-organisms.
