The present invention concerns a method for specifically detecting and identifying, using a reaction medium comprising at least one esterase enzymatic substrate.

[object Object]

A reaction medium for detecting and/or identifyingbacteria, comprising a combination of two enzymatic substrates for alpha-glucosidase.

A reaction medium for the culture and/or detection and/or identification of bacteria of thegenus includes at least one siliceous compound, where the siliceous compound is a nonpolar silica. A method for detecting and/or identifying bacteria of thegenus, includes bringing a sample that may contain bacteria of thegenus into contact with a reaction medium comprising at least one siliceous compound, incubating, and detecting the presence of bacteria of thegenus.

A reaction medium for detecting and/or identifying Methicillin-resistant(MRSA) bacteria, comprising a predetermined combination of two antibiotics, a first antibiotic which belongs to the cephalosporin family and a second antibiotic, said first and second antibiotics each being at a sub-inhibitory concentration.

The present invention relates to a reaction medium for-group(and) andbacteria, comprising The invention also relates to the use of this medium for isolating and identifying-group(and) and Finally, the invention relates to a method for identifyingandbacteria, according to which beta-galactosidase activity is detected for identifyingand the acidification of a sugar is detected for revealing

The invention concerns a medium for specific detection ofand/or discrimination between positive-coagulaseand negative-coagulase enablingto isolate bacteria of the genus staphylococcus and identify thespecies, which use at least an enzymatic substrate, preferably a chromogenic or fluorescent agent, and still more preferably consisting of an indoxyl or naphthol base. The invention also concerns a method for identifying, and optionally counting,using such a medium. It consists of aculture medium and at least an enzymatic substrate enabling testing of an &#x3b1;-glucosidase activity. The invention is particularly applicable in the field of diagnosis.

The present invention concerns a method for specifically detecting and identifyingusing a reaction medium comprising at least one &#x3b1;-glucosidase enzymatic substrate.
