Abstract

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.

摘要

采用培养技术和扫描电子显微镜对营养不良的BIO 8262 Nij叙利亚仓鼠以及作为对照的昆士兰：叙利亚仓鼠胃肠道的微生物区系进行了研究。对食管、前胃、胃、小肠、盲肠和粪便进行了评估，以检测肠杆菌科、葡萄球菌、乳酸杆菌、链球菌、梭菌、拟杆菌和酵母菌的存在情况。正常仓鼠的食管、前胃和胃中酵母菌含量较低；其他部位未发现酵母菌。在所有肠道段中均发现葡萄球菌和肠杆菌科的含量相对较低；在肠道上部也发现拟杆菌含量较低。其他细菌组在所有段中含量相对较高。在营养不良的BIO 8262 Nij仓鼠的肠道中未检测到肠杆菌科和酵母菌。扫描电子显微镜显示两种仓鼠菌株在黏附方面没有差异。
