Abstract
The indirect fluorescent antibody test was used to detect antibodies to Anaplasma marginale in serum samples collected from cattle in the Red River Plains and South-east areas of Louisiana. Convenience sampling of herd clusters was used. A reactor rate of 7.8% was found in 11,085 samples. Beef cattle had a 11.2% reactor rate compared with 3.8% for dairy cattle. The Angus and Angus cross-breed group had the highest reactor rate.
摘要
采用间接荧光抗体试验检测从路易斯安那州红河平原和东南部地区的牛采集的血清样本中抗边缘无形体的抗体。采用畜群集群的便利抽样方法。在11085份样本中发现反应率为7.8%。肉牛的反应率为11.2%，而奶牛为3.8%。安格斯和安格斯杂交品种组的反应率最高。
