SELECTIVE MULTIPURPOSE CULTURE MEDIUM FOR ISOLATING AND SELECTING COLISTIN-RESISTANT AND VANCOMYCIN-RESISTANT BACTERIA

摘要

The present invention relates to a selective multipurpose culture medium for isolating and selecting, from samples containing them, bacteria chosen from (a) colistin-resistant fermentative and nonfermentative Gram-negative bacteria and (b) vancomycin-resistant Gram-positive bacteria, characterized in that it essentially consists of an agar with a chromogenic agent added thereto, consisting of bromocresol purple, a sugar and two antibiotic compounds consisting of vancomycin and colistin. The present invention also relates to a method for isolating and selecting said colistin-resistant Gram-negative bacteria and vancomycin-resistant Gram-positive bacteria by culturing a sample of bacteria containing same, using a solid culture medium according to the invention.
