Abstract

Background

Toxoplasmosis, caused by Toxoplasma gondii, is a zoonotic disease affecting public health and wildlife conservation, including nonhuman primates. This study evaluated the presence of T. gondii in three neotropical tamarin species (Leontocebus fuscicollis, Saguinus geoffroyi and Saguinus oedipus) at Barranquilla Zoo, Colombia.

Methods

A retrospective analysis (2017–2022) was conducted on 17 tamarins. Clinical evaluations and blood samples were used to detect IgG antibodies via latex agglutination test. Necropsies and histopathological analyses were used to assess organ lesions associated with T. gondii.

Results

In 2017, 35% (6/17) of the participants tested seropositive, increasing to 100% (13/13) by 2022. Antibody titer fluctuations were noted, with significant increases in female S. oedipus. Four deaths occurred, two linked to active or chronic infections. Stray cats and rodents in the zoo were identified as possible transmission vectors.

Conclusions

This study highlights T. gondii exposure to tamarins, associated mortality, and diagnostic challenges. Recommendations include stray cat management, pest control, and the exploration of vaccines to reduce transmission risks.

哥伦比亚三种绢毛猴（geoffroroyi Saguinus oedipus Saguinus and Leontocebus fuscicollis）迁地后刚地弓形虫的发生

弓形虫病是由刚地弓形虫引起的一种人畜共患疾病，影响公共卫生和野生动物保护，包括非人灵长类动物。本研究评估了哥伦比亚巴兰基利亚动物园3种新热带绢毛猴（fuscicollis Leontocebus， geoffroyi Saguinus和oedipus Saguinus）中弓形虫的存在。方法对2017-2022年17只绢毛猴进行回顾性分析。采用临床评价和血液样本进行乳胶凝集试验检测IgG抗体。尸检和组织病理学分析用于评估与弓形虫相关的器官病变。结果2017年，35%（6/17）的参与者血清检测呈阳性，到2022年增加到100%（13/13）。注意到抗体滴度波动，雌性俄狄浦斯蛇明显增加。发生了4例死亡，其中2例与活动性或慢性感染有关。动物园的流浪猫和啮齿动物被确定为可能的传播媒介。本研究强调了弓形虫暴露于绢毛猴、相关死亡率和诊断挑战。建议包括流浪猫管理、害虫控制和探索疫苗以减少传播风险。
