摘要
为了解新疆地区部分规模化奶牛场牛传染性鼻气管炎病毒、牛病毒性腹泻病毒、牛呼吸道合胞体病毒、牛副流感3型病毒和牛支原体的感染状况，本试验采用酶联免疫吸附试验（ELISA ）检测试验区奶牛场中未接种上述疫病疫苗的奶牛血清，对自然感染状况进行评估。结果表明，牛传染性鼻气管炎病毒抗体平均阳性率为82．5％（66/80），牛病毒性腹泻病毒抗体平均阳性率为88．8％（71/80），牛呼吸道合胞体病毒抗体平均阳性率为82．5％（66/80），牛副流感3型病毒抗体平均阳性率为91．3％（73/80），牛支原体抗体平均阳性率86．3％（69/80）；试验区牛场均存在2种～5种病原的混合感染现象，其中5种病原混合感染率为71．3％。结果显示在新疆地区部分规模化奶牛场中普遍存在上述5种病原的感染，且混合感染现象明显，奶牛生产中必须加强这些疫病的防控工作。
In order to find out the infection status of infectious bovine rhinotracheitis virus （IBRV） ,bovine viral di-arrhea virus（BVDV） ,and bovine respiratory syncytial virus （BRSV） ,bovine parainfluenza 3 virus（BPIV3） and Mycoplasma bovis infections in several large-scale dairy cow farms in Xinjiang ,the enzyme-linked immunosorbent assay （ELISA） was used to detect bovine sera from pre-immune dairy cows and to evaluate naturally occurred in-fections of these diseases in experimental dairy farms .The results showed that the average antibody positive rates for infectious bovine rhinotracheitis virus ,bovine viral diarrhea virus ,bovine respiratory syncytial virus ,parainflu-enza virus 3 ,and Mycoplasma bovis were 82 .5% （66/80） ,88 .8% （71/80） ,82 .5% （66/80） ,91 .3% （73/80） and 86 .3% （69/80） ,respectively .There was a mixed infection with 2 to 5 kinds of pathogens in the investigated dairy farms ,and mixed infection with these five pathogens was reached to 71 .3% .These results indicated that there was widespread infection with five pathogens alone and together in these large-scale dairy farms .It suggested that the prevention and control of infectious diseases with five pathogens should be strengthened in order to provide safe and healthy dairy products to the consumers .
