Abstract

The protozoan Toxoplasma gondii, which can infect a wide range of warm-blooded animal hosts, including humans, causes the zoonosis toxoplasmosis. This parasite affects dogs, and infections may lead to neuromuscular problems in them. Likewise, dogs can act as sentinels for toxoplasmosis, providing valuable information on the prevalence of the parasite in a given area. Therefore, the aim of the present study was to determine the seroprevalence of T. gondii in dogs from Lima City in Peru. A total of 120 sera from domestic dogs were used to detect IgG antibodies using the modified agglutination test (MAT). Forty dogs tested positive for the MAT, indicating a seroprevalence of 33.3 % (CI_95% 24.9–41.8 %). Only the variable sex demonstrated a statistical association with exposure to T. gondii in dogs, with males exhibiting odds of 2.40 (CI_95% 1.10–5.37) compared to females. Since dogs are the main human pet, they could act as sentinels to estimate the situation of toxoplasmosis in humans. Our findings highlight the need to continue epidemiological surveillance of T. gondii in canine populations in various localities of Peru.

秘鲁利马市家犬的弓形虫血清流行率

弓形虫（Toxoplasma gondii）这种原生动物可感染包括人类在内的多种温血动物宿主，导致人畜共患病弓形虫病。这种寄生虫会影响狗，感染后可能会导致狗的神经肌肉问题。同样，狗也可以作为弓形虫病的哨兵，为特定地区的寄生虫流行情况提供有价值的信息。因此，本研究旨在确定秘鲁利马市狗的弓形虫血清流行率。研究人员使用改良凝集试验（MAT）检测了 120 份家犬血清中的 IgG 抗体。40 只犬的 MAT 检测结果呈阳性，表明血清流行率为 33.3%（CI95% 24.9-41.8%）。只有性别变量与狗感染淋病的几率有统计学关联，雄性狗感染淋病的几率为 2.40（CI95% 为 1.10-5.37），而雌性狗感染淋病的几率为 2.40（CI95% 为 1.10-5.37）。由于狗是人类的主要宠物，因此它们可以作为估计人类弓形虫感染情况的哨兵。我们的研究结果突出表明，有必要继续对秘鲁各地犬类群体中的弓形虫进行流行病学监测。

期刊介绍： Veterinary Parasitology: Regional Studies and Reports focuses on aspects of veterinary parasitology that are of regional concern, which is especially important in this era of climate change and the rapid and often unconstrained travel of people and animals. Relative to regions, this journal will accept papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites within the field of veterinary medicine. Also, case reports will be considered as they add to information related to local disease and its control; such papers must be concise and represent appropriate medical intervention. Papers on veterinary parasitology from wildlife species are acceptable, but only if they relate to the practice of veterinary medicine. Studies on vector-borne bacterial and viral agents are suitable, but only if the paper deals with vector transmission of these organisms to domesticated animals. Studies dealing with parasite control by means of natural products, both in vivo and in vitro, are more suited for one of the many journals that now specialize in papers of this type. However, due to the regional nature of much of this research, submissions may be considered based upon a case being made by the author(s) to the Editor. Circumstances relating to animal experimentation must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences (obtainable from: Executive Secretary C.I.O.M.S., c/o W.H.O., Via Appia, CH-1211 Geneva 27, Switzerland).
