Colorex™ Acinetobacter MDR

Colorex™ Acinetobacter MDR

Colorex™Acinetobacter MDR is a chromogenic medium for the detection of multi-drug resistant (MDR) Acinetobacter spp. Positive colonies exhibit a distinct red colouration with a pale grey centre enabling easy interpretation amongst blue, violet or colourless colonies that may be produced by other Gram –ve bacteria. Gram +ve bacteria and yeast are inhibited on this medium. Limitations:

1.  Some Pseudomonas, Stenotrophomonas and Burkholderia spp. may form pale red colonies on this medium but are readily distinguishable due to differences in colonial morphology compared to the Acinetobacter spp. An oxidase test will readily differentiate any Pseudomonas spp.

2. Some Enterobacteriaceae isolates may form blue colonies on this medium.

3. Definitive MDR characterisation may require additional antibiotic susceptibility testing.
