Prevalence of Toxoplasma gondii and Neospora caninum antibodies in sera of 325 dogs in 11 villages inhabited by the Tapirapé and Karajá ethnic groups in the south of the Brazilian Amazon was determined by the use of an indirect fluorescence antibody test. Antibodies (cutoff 1:16) to T. gondii were found in 169 (52%) and to N. caninum (cut-off 1:50) in 32 (9.8%) of 325 dogs. Seropositivity for both parasitic infections was widely prevalent in dogs from these villages and was higher in older dogs, indicating post-natal transmission.
通过间接荧光抗体试验，测定了巴西亚马逊南部塔皮拉佩和卡拉亚族居住的11个村庄中325只犬血清中弓形虫和犬新孢子虫抗体的流行情况。在325只犬中，169只（52%）检测到针对弓形虫的抗体（临界值为1:16），32只（9.8%）检测到针对犬新孢子虫的抗体（临界值为1:50）。这两种寄生虫感染的血清阳性在这些村庄的犬中广泛存在，且在老年犬中更高，表明存在产后传播。
