摘要
本研究通过流行病学、临床和病理变化以及病原学鉴定,确定1986年秋在云南路南发生的莎能奶山羊急性腹泻的病原为D型产气荚膜杆菌。临床上,除可见到最急性型和急性型的病羊外,还从药物防治和免疫接种过的成年羊中发现慢性型病例,这与国外的记载相一致。经气相色谱技术对6株产气荚膜杆菌进行的鉴定,其色谱可显出该菌特征性“指纹”峰,并能清晰地分辨出本菌与羊的其他3种主要梭菌的不同。
This papar reports the etiology of acuta diarrhea of Saanen dairy goats from Lunan, Yunnan Province in autumn, 1986. Five clostridia strains were isolated from the faeces of acute diarrhea and ileac. contents of natural diet goats. The isolation rate was 100%. The number of colonies reached 10~5-10~8 Cfu/ g. On the basis of epidemiological, Clinical and pathological features of the disease, and its etiological properties, the major cause of the diarrheal disease of dairy goats is evidenced as Clostridium perfringens. In clinic, apart from the types of the acutest and acute cases, a chronic case was discovered in adult animals vaccinated which is similar to that recorded abroad. In pathogenic research. We have identified 6 strains of Clostridia perfringens by gas chromatograph. The peake of the key fingerprint of the bacteria can be showed distinctly on chromatograph, and enabled to differentiate three other clostridia of goat from Clostridium perfringens.
