Abstract

There is a lack of information concerning the seroprevalence of Toxoplasma gondii infection in rabbits in northern Mexico. Through a cross sectional study, antibodies to T. gondii were determined in 429 domestic rabbits in Durango State, Mexico using the modified agglutination test. Rabbits were raised in 29 properties in 6 municipalities. Overall, antibodies to T. gondii were found in 70 (16.3%) of 429 rabbits, with titers of 1:25 in 42, 1:50 in 19, 1:100 in 5, 1:200 in 3, and 1:800 in 1. Seropositive rabbits were found in 21 (72.4%) of 29 properties, including 16 of 21 homes, 4 of 5 farms, and 1 of 3 pet shops. This is the first study of T. gondii infection in rabbits in Durango, Mexico. Results indicate that infected rabbits are a potential source of T. gondii infection in humans in Durango State.

摘要

有关墨西哥北部兔弓形虫感染血清流行率的信息匮乏。本横断面研究采用改良凝集试验，检测了来自墨西哥杜兰戈州 29 处饲养场的 429 只家兔的弓形虫抗体。结果显示，在 429 只兔中，70 只（16.3%）存在弓形虫抗体，其中 42 只兔的效价为 1:25，19 只兔为 1:50，5 只兔为 1:100，3 只兔为 1:200，1 只兔为 1:800。29 处饲养场中，有 21 处（72.4%）存在阳性兔，包括 21 处家庭饲养场中的 16 处、5 处农场中的 4 处和 3 处宠物店中的 1 处。这是杜兰戈州首例有关兔弓形虫感染的研究。结果表明，感染兔可能是杜兰戈州人类感染弓形虫的潜在传染源。
