【摘要】：为了摸清宁夏地区肉牛和奶牛牛支原体(Mycoplasma bovis)感染情况及流行趋势,采用酶联免疫吸附试验(ELISA)对2013年—2015年采集自宁夏地区肉牛主要养殖区的57个肉牛场886份血清和奶牛主要养殖区的39个奶牛场1 088份血清进行检测。结果发现,2013年抽检的16个奶牛场阳性率为32.17%(148/460),场群阳性率100%(16/16);2014年抽检的银川地区12个奶牛场,阳性率为26.52%(61/230),场群阳性率100%(12/12);2015年抽检的11个奶牛场,阳性率为44.97%(179/398),场群阳性率100%(11/11);2014年阳性率较2013年和2015年低,2015年最高,2013年与2014年阳性率差异不显著(P0.05),2015年与2013年和2014年的阳性率差异极显著(P0.01)。2013年抽检的19个肉牛场,阳性率为7.26%(18/248),场群阳性率为26.32%(5/19);2014年抽检的38个肉牛场,阳性率为5.02%(32/638),场群阳性率为50%(19/38);2014年较2013年的阳性率低,但差异不显著(P0.05),而且部分地区和肉牛场未检测到牛支原体阳性血清。上述结果表明,宁夏地区奶牛养殖场牛支原体感染状况较为严重,应引起养殖场的高度重视。
[Abstract]:In order to find out the situation and epidemic trend of Mycoplasma bovisis infection in beef cattle and cow in Ningxia, Elisa was used to detect 886 serum samples from 57 beef cattle farms in Ningxia from 2013 to 2015 and 1,088 serum samples from 39 dairy cattle farms in the main dairy breeding areas in Ningxia from 2013 to 2015. The positive rate of 16 dairy farms tested was 32.17 / 4600.The positive rate of farm groups was 100% 16 / 16; 12 dairy farms in Yinchuan district were sampled in 2014. The positive rate was 26.52% 61 / 230%, the positive rate of farm group was 100% / 12%; 11 dairy farms were sampled in 2015. The positive rate was 44.97 / 179 / 398m, the positive rate of farm group was 100 / 11 / 11a; the positive rate of 2014 was lower than that of 2013 and 2015, the highest in 2015, and the difference between 2013 and 2014 was not significant (P0.05). The difference between 2015 and 2013 and 2014 was extremely significant (P 0.01). In 2013, 19 cattle farms were tested. The positive rate is 7.26% 18 / 248%, the positive rate of farm group is 26.32% / 19%; the positive rate of 38 beef farms tested in 2014 is 5.02% 32% 638%, and the positive rate of field group is 50% 19 / 38%; the positive rate of 2014 is lower than that of 2013. But the difference was not significant (P 0.05), and no positive serum of Mycoplasma bovis was detected in some areas and beef farms. The results indicated that the infection of Mycoplasma bovis in dairy cattle farms in Ningxia was serious and should be attached great importance to.
