Opportunistic bacteria isolated from the caecum of rabbits with mucoid enteritis

摘要: Abstract The caecal microflora of rabbits with mucoid enteritis was investigated by aerobic and anaerobic techniques. Escherichia coli identified in the majority faecal cultures from diseased following bacteria were occasionally either presence or absence E. coli: Proteus mirabilis, Alcaligenes, Citrobacter, Acinetobacter, Bacillus sp. Klebsiella . P. mirabilis isolated did not produce heat-stable heat-labile toxins. None but all isolates examined exhibited mannose-sensitive haem-agglutination human guinea-pig erythrocytes. There no evidence in-vitro attachment to intestinal epithelial cells. Light electron microscopy examination rabbits' sections revealed closely associated cells only four 22 cases studied. shown be resistant a sulphonamide drug at concentrations similar those presently used rabbit breeding industry control disease. Re-inoculation failed induce enteritis. amoeba, viruses, fungi, Chlamydia, Campylobacter, Clostridium perfringens difficile , heterogeneity animals raised question whether micro-organism primary aetiological agent. so often implicated appear opportunists.
