Abstract

Carcasses of northern fur seal pups, Callorhinus ursinus, collected from the rookeries of Bering Island (n = 133), were examined for hookworms Uncinaria spp. The parasite was found in 90% of the pups from the Severo-Zapadnoe rookery and in 45% of the pups from the Severnoe rookery. This difference in prevalence of nematode infection between the rookeries is associated with the type of substrate, as well as with the pattern of distribution of the seal reproductive groups on each of the rookeries.

白令岛群中北部海狗幼体Callorhinus ursinus的非cin虫病研究，2011–2012年

摘要

从白令岛群（n = 133）收集的北部海狗幼体Callorhinus ursinus的尸体被检查是否有钩虫Uncinaria spp。在Severo-Zapadnoe种群的90％幼崽中和Severnoe种群的45％的幼崽中发现了这种寄生虫。群体之间的线虫感染流行率的这种差异与底物的类型以及在每个群体上的海豹繁殖基团的分布方式有关。
