Differences in the intestinal microflora of normal and dystrophic BIO 8262 Nij Syrian hamsters.
The microflora of the gastro-intestinal tract of dystrophic BIO 8262 Nij Syrian hamsters and Kun:Sh Syrian hamsters as controls was investigated by means of culturing techniques and scanning electron microscopy. The oesophagus, forestomach, stomach, small intestine, coecum and faeces were assessed for the presence of Enterobacteriaceae, Staphylococci, Lactobacilli, Streptococci, Clostridia, Bacteroides and yeasts. The normal hamsters showed low levels of yeasts in the oesophagus, forestomach and stomach; yeasts were not present in the other compartments. Relatively low levels of Staphylococci and Enterobacteriaceae were found in all gut segments; also Bacteroides was found in low levels in the upper part of the gut. The other groups of bacteria showed relatively high levels in all segments. In dystrophic BIO 8262 Nij hamsters no Enterobacteriaceae and yeasts have been detected in the gut. Scanning electron microscopy showed no difference in adhesion between both hamsters strains.
