| 摘 要： | 本试验选取新疆垦区七个试验牛场,临床调查和试剂诊断,检测奶牛712头,采集奶牛乳房炎阳性乳样314份。其中,奶牛隐性乳房炎阳性检出率平均为36.3%,临床性奶牛乳房炎为16.7%;采集阳性奶样经试验分离鉴定,革兰氏阳性菌仍是引起奶牛乳房炎的主要致病菌,但金色葡萄球菌已基本取代链球菌成为主要的致病菌,其检出率为78.98%。另外,常见环境性致病菌如沙门氏菌、大肠杆菌已明显减少,检出率仅为21.1%和9.24%。相反,绿脓杆菌和蜡样芽孢杆菌的检出率明显增加,其检出率为5.41%和11.15%,而且绿脓杆菌和隐球菌已经成为引起临床性乳房炎爆发的两种新的病原,其中隐球菌已经成为造成顽固性乳房炎的又一种新型病原。

| Abstract: | The experiment selected seven testing cattle farms in Xinjiang Corps to examine 712 dairy cattle by clinical investigations and reagent diagnosis,and collected 314 positive samples in the final.Postive average detecting rate for subclinical mastitis was 36.3% but detecting rate for clinical mastitis was 16.7%. In the positive samples,G~+ bacteria was still the main pathogen causing diary cattle mastitis,and S.aureus with a detecting rate of 78.98% had become the most important pathogen instead of streptococcus basically.Besides,common environmental pathogens such as salmonella and E.coli decreased obviously with detecting rates of 21.1% and 9.24% respectively;contrarily,P.aeruginosa and B.cereus increased evidently,their detecting rates were 5.41% and 11.15% respectively.P.aeruginosa and Cryptococcus had caused outbreaks of clinical mastitis,and Cryptococcus,to some degree,had become another new pathogen causing pertinacious mastitis. |
