Epidemic infection caused by Citrobacter rodentium in a gerbil colony

Non-motile, Gram-negative rods, isolated from the intestinal tract and kidney of several dead animals in a gerbil colony, were identified as Citrobacterrodentium (formerly included in C freundii species) on the basis of 31 biochemical tests. The isolates were tested against 40 antimicrobial agents a...

Description
Summary:Non-motile, Gram-negative rods, isolated from the intestinal tract and kidney of several dead animals in a gerbil colony, were identified as Citrobacterrodentium (formerly included in C freundii species) on the basis of 31 biochemical tests. The isolates were tested against 40 antimicrobial agents and were all susceptible to ticarcillin plus clavulanate, ceftazidime and most of the quinolones studied, but were all resistant to most of the penicillins and aminoglycosides tested, and to fosfomycin, metronidazole and tiamulin. This bacterial species has been primarily associated with transmissible murine colonic hyperplasia, and this appears to be the first report of an epidemic infection in a gerbil colony with a fatal outcome in most of the animals affected.
