Recent evidence of bluetongue (BT) virus infection of livestock in scattered localities in the neotropics prompted a serologic survey of cattle in Colombia and Costa Rica. In Costa Rica 48.1% of 1435 bovine animals had BT virus antibody in the agar gel precipitation test (AGPT). In Colombia 51.8% of 635 cattle were AGPT-positive for BT virus. Antibody prevalence ranged from over 50% in the lowlands to 0% in Costa Rica and 19% in Colombian cattle above 2000 m altitude. Neutralization tests indicated that Costa Rican cattle had been exposed to BT virus types 6, 12, 14 and 17.
近期在新热带地区一些分散地点出现家畜感染蓝舌病（BT）病毒的证据，促使对哥伦比亚和哥斯达黎加的牛群进行了血清学调查。在哥斯达黎加，1435头牛中有48.1%在琼脂凝胶沉淀试验（AGPT）中检测出蓝舌病病毒抗体。在哥伦比亚，635头牛中有51.8%的牛在AGPT检测中呈蓝舌病病毒阳性。抗体流行率在低地地区超过50%，而在哥斯达黎加海拔高于2000米的地区为0%，在哥伦比亚海拔高于2000米的牛群中为19%。中和试验表明，哥斯达黎加的牛曾接触过6型、12型、14型和17型蓝舌病病毒。
