富平关中奶山羊临床型乳房炎病原菌的分离鉴定

Isolation and Identification of Mastitis Pathogen from Guan Zhong Dairy Goats in Fuping City

为进一步探讨关中奶山羊乳房炎感染病原菌的情况,对富平县三个不同乡镇的79头患病奶山羊,共118份奶样进行分离鉴定,共分离出7种共126个菌株。其中大肠杆菌36株,占28.5%;金黄色葡萄球菌28株,占22.2%;绿脓杆菌23株,占18.3%;链球菌21株,占16.7%;变形杆菌8株,占6.3%;蜡样芽孢杆菌6株,占4.8%;酵母菌4株,占3.2%。认为该研究区域的关中奶山羊乳房炎主要是由大肠杆菌,金黄色葡萄球菌、绿脓杆菌、链球菌所致。

The purpose was to identify the type of acute mastitis pathogen of Guanzhong dairy goats.118 samples from 79 sick dairy goats were collected,from which the 126 strains of bacterium were isolated and identifled separately.The result including 36 of Escherichia coli(28.5%),28 of Staphylococcus aureus(22.2%),23 of Pseudomonas aeruginosa(18.3%),21 of Streptococcus(16.7%),8 of Proteus(6.3%),6 of Cerea Spore Bacilli(4.8%),4 of Yeast(3.2%).Positive rate of pathogen of milk samples is 79.1 3%and mixed infection rate is 20%.The major pathogens of clinical mastitis in Fuping city are Escherichia coli,Staphylococcus aureus,Pseudomonas aeruginosa and Streptococcus.
