【摘要】 采用微生态学方法,对SPF鸡和普通鸡嗉囔、腺胃、回肠、盲肠和直肠5个部位的梭杆菌、真杆菌、消化球菌、双歧杆菌、乳酸杆菌、类杆菌、肠球菌、葡萄球菌和肠杆菌等9种主要正常菌群进行定性、定量分析。结果表明,SPF鸡嗉囔中真杆菌、梭杆菌、双歧杆菌、类杆菌、葡萄球菌和肠杆菌数高于普通鸡,其中真杆菌、梭杆菌、葡萄球菌和肠杆菌数差异极显著(P<0.01);腺胃中梭杆菌、真杆菌、消化球菌、双歧杆菌、乳酸杆菌、类杆菌和肠杆菌数高于普通鸡,其中真杆菌数差异显著(P<0.05);回肠中真杆菌、双歧杆菌、类杆菌、葡萄球菌和肠杆菌数高于普通鸡,其中类杆菌数差异极显著(P<0.01);盲肠中梭杆菌、消化球菌、双歧杆菌、乳酸杆菌和肠球菌数低于普通鸡,其中乳酸杆菌数差异显著(P<0.05);直肠中各菌数量都低于普通鸡,其中双歧杆菌和乳酸杆菌差异显著(P<0.05)。更多还原

【Abstract】 Qualitative and quantitive investigations wasere carried out on the intestinal bacterial community in SPF and ordinary chicken.Nine kinds of dominant intestinal bacteria were selected and counted on various selective media.The results showed that when comparing SPF with ordinary chicken,significant differences were found in the number of clostridium,eubacterium,staphylococcus and escherichia coli in crop (P<0.01),staphylococcus(P<0.05) in proventriculus,bacteroides (P<0.01) in ileum,lactobacillus (P<0.05) in caecum,and bifidobacterium and lactobacillus (P<0.05) in rectum.更多还原
