报告了1997-1998年在哈萨克斯坦进行的牲畜血清学调查的结果。检测了958份牛、绵羊和山羊血清中口蹄疫、蓝舌病、流行性出血性疾病、牛瘟和小反刍兽疫病毒以及布鲁氏菌的抗体。我们还调查了牲畜的疫苗接种状况，并将其与1991年独立以来兽医规定的变化联系起来。对于官方监测的2种疾病（口蹄疫和布鲁氏菌病），我们的结果与官方数据相似，尽管我们发现2个地区的布鲁氏菌病水平显著较高，并且普遍对口蹄疫疫苗接种状况一无所知。BT病毒的血清阳性率为23%，血清阳性动物广泛存在，表明具有地方性，尽管以前没有报道过这种疾病。我们发现了一些EHDV和PPRV的血清阳性，这可能表明这些疾病也存在于哈萨克斯坦。一个层次模型表明，口蹄疫和BT病毒的血清阳性率聚集在农场/村庄一级，而不是在一个更大的空间尺度。这对于口蹄疫来说是出乎意料的，因为口蹄疫的疫苗接种政策在区（县）一级各不相同。
The results of a serological survey of livestock in Kazakhstan, carried out in 1997-1998, are reported. Serum samples from 958 animals (cattle, sheep and goats) were tested for antibodies to foot and mouth disease (FMD), bluetongue (BT), epizootic haemorrhagic disease (EHD), rinderpest (RP) and peste des petits ruminants (PPR) viruses, and to Brucella spp. We also investigated the vaccination status of livestock and related this to changes in veterinary provision since independence in 1991. For the 2 diseases under official surveillance (FMD and brucellosis) our results were similar to official data, although we found significantly higher brucellosis levels in 2 districts and widespread ignorance about FMD vaccination status. The seroprevalence for BT virus was 23%, and seropositive animals were widespread suggesting endemicity, despite the disease not having being previously reported. We found a few seropositives for EHDV and PPRV which may suggest that these diseases are also present in Kazakhstan. An hierarchical model showed that seroprevalence to FMD and BT viruses were clustered at the farm/village level, rather than at a larger spatial scale. This was unexpected for FMD, which is subject to vaccination policies which vary at the raion (county) level.
