Abstract

During the period December 1998-May 2000, 900 local goats slaughtered at the Irbid Abattoir (northern Jordan) were examined for the larval instars of Przhevalskiana silenus. Of 900 goats, 10% (95% CI: 9,13) were infested with P. silenus larvae. Only the second and third larval instars were seen. A multiple-regression analysis (with the error variance described by the negative-binomial function) suggested that infestation depended on the month of sampling, and that infestation with live larvae was associated with a poorer carcass. The percentage of infested goats and the mean monthly total number of larvae per goat peaked in samples taken in the autumn and winter. Larval numbers were highly aggregated: most animals had no larvae but the maximum was 69. Analysis of the pattern of aggregation suggested that the best model fit was one in which the larvae counts per goat varied with the monthly prevalence.

摘要

在1998年12月至2000年5月期间，对在伊尔比德屠宰场（约旦北部）宰杀的900只当地山羊进行了普氏原羚幼虫龄期检查。在900只山羊中，10%（95%置信区间：9,13）感染了普氏原羚幼虫。仅发现了第二和第三幼虫龄期。多元回归分析（误差方差由负二项式函数描述）表明，感染情况取决于采样月份，活幼虫感染与较差的胴体有关。感染山羊的百分比和每只山羊每月幼虫总数的平均值在秋季和冬季采集的样本中达到峰值。幼虫数量高度聚集：大多数动物没有幼虫，但最多有69只。聚集模式分析表明，最佳模型拟合是每只山羊的幼虫计数随每月患病率变化的模型。
