The objectives of this cross-sectional study were to estimate the seroprevalence of infectious bovine rhinotracheitis (IBR, BHV-1) and bovine viral diarrhea virus (BVDV) in a population of non-vaccinated, double purpose, dairy and beef herds in the Pacific Region of Central Costa Rica. Blood samples were collected from a total of 496 animals from 35 herds. Sera were tested for antibodies against BHV-1(IBR) and BVDV types 1 and 2 using serum neutralization test. The average number of animals tested in each herd for each of the viruses was 14. Overall individual seroprevalence was 48%, 27%, and 19% for IBR, BVDV type 1, and BVDV type 2, respectively. Median within-herd seroprevalence for IBR, BVDV type 1 and type 2 were 43%, 27%, and 24%, respectively.
本横断面研究的目的是估计哥斯达黎加中部太平洋地区未接种疫苗的兼用型奶牛和肉牛群体中传染性牛鼻气管炎（IBR，BHV-1）和牛病毒性腹泻病毒（BVDV）的血清流行率。从35个牛群的496只动物中采集了血样。使用血清中和试验检测血清中针对BHV-1（IBR）以及1型和2型BVDV的抗体。每个牛群中针对每种病毒检测的动物平均数量为14只。IBR、1型BVDV和2型BVDV的个体总体血清流行率分别为48%、27%和19%。IBR、1型BVDV和2型BVDV在牛群内的血清流行率中位数分别为43%、27%和24%。
