摘要

Ostertagia (O.) ostertagi是一种常见的牛寄生虫，可以在动物进入牧场的所有牛场中找到。为了评估牛群中抗O. ostertagi抗体的存在，使用商业ELISA检测(SVANOVIR®O. ostertagi Ab ELISA，瑞典Svanova)对散装罐乳(BTM)样品进行了评估。样本(n=830)从爱沙尼亚、拉脱维亚、立陶宛和波兰的奶牛群中收集。波兰和爱沙尼亚的平均BTM光密度比(ODR)分别为0.400和0.493。在立陶宛(0.695)和拉脱维亚(0.703)收集的样本中获得了较高的BTM odr，这可能与立陶宛和拉脱维亚每头奶牛每天产奶量减少0.75-1.2千克有关。2011年在波兰使用BTM样本进行了第一次牡蛎病调查。据我们所知，这是在爱沙尼亚、拉脱维亚和立陶宛首次使用BTM ELISA odr来评估牛的卵巢鳞病。

Presence of antibodies against Ostertagia ostertagi in bulk tank milk from cattle herds in the northeastern Baltic countries of Europe

Ostertagia (O.) ostertagi is a common cattle parasite that can be found on all cattle farms where animals have access to pastures. To evaluate the presence of anti- O. ostertagi antibodies in cattle herds, bulk tank milk (BTM) samples were evaluated using a commercial ELISA test (SVANOVIR® O. ostertagi Ab ELISA, Svanova, Sweden). Samples (n=830) were collected from dairy cattle herds in Estonia, Latvia, Lithuania, and Poland. The average BTM optical density ratio (ODR) values in Poland and Estonia were 0.400 and 0.493, respectively. Higher BTM ODRs were obtained in samples collected in Lithuania (0.695) and in Latvia (0.703), which may correlate with the reduction in milk yield by 0.75–1.2 kg of milk per cow per day in Lithuania and Latvia. The first investigations on ostertagiosis using BTM samples were conducted in Poland in 2011. To our knowledge, this is the first report to use BTM ELISA ODRs to evaluate ostertagiosis in cattle in Estonia, Latvia, and Lithuania.

期刊介绍： The Berliner und Münchener Tierärztliche Wochenschrift is an open access, peer-reviewed journal that publishes contributions on all aspects of veterinary public health and its related subjects, such as epidemiology, bacteriology, virology, pathology, immunology, parasitology, and mycology. The journal publishes original research papers, review articles, case studies and short communications on farm animals, companion animals, equines, wild animals and laboratory animals. In addition, the editors regularly commission special issues on topics of major importance. The journal’s articles are published either in German or English and always include an abstract in the other language.
