Abstract

The prevalence of anti-Toxoplasma gondii antibodies was evaluated by the indirect immunofluorescent-antibody test in serum of 57 wild canids from three different species: Lycalopex gymnocercus, Cerdocyon thous and Dusicyon vetulus from the northeast, southeast and southern regions of Brazil. The prevalence was 35.1%, with 20 of the 57 canids demonstrating antibodies anti-T. gondii at dilutions of 1:16 in 2, 1:32 in 4, 1:64 in 2, 1:128 in 2, 1:256 in 6, 1:512 in 2 and 1:2048 in 2 animals. None of the D. vetulus were positive. Among the L. gymnocercus 11 (91.7%) of the 12 samples were positive and among C. thous 9 (60%) of the 15 had antibodies anti-T. gondii.

摘要

通过间接免疫荧光抗体试验，对来自巴西东北部、东南部和南部地区的三种不同野生犬科动物（草原狐、食蟹狐和南美胡狼）的57份血清进行检测，以评估抗刚地弓形虫抗体的流行情况。流行率为35.1%，57只犬科动物中有20只在不同稀释度下显示出抗刚地弓形虫抗体，其中2只在1:16稀释度、4只在1:32稀释度、2只在1:64稀释度、2只在1:128稀释度、6只在1:256稀释度、2只在1:512稀释度以及2只在1:2048稀释度下呈阳性。南美胡狼均为阴性。草原狐的12份样本中有11份（91.7%）呈阳性，食蟹狐的15份样本中有9份（60%）具有抗刚地弓形虫抗体。
