Abstract

Leishmaniases are a group of neglected diseases of significant public health concern, with Brazil being the primary focus of this disease in the Americas. The municipality of Sobral, in the state of Ceará, is a historical focus of visceral leishmaniasis in both humans and dogs, but data on Leishmania spp. infections in cats are limited. Between April 2021 and February 2022, 205 cats from a referral hospital population were sampled and tested for Leishmania spp. by real-time PCR. Eight cats (3.9%; 95% CI: 1.7–7.5%) tested positive. Among these, three (37.5%) displayed clinical signs compatible with feline leishmaniosis. Non-domiciled cats showed significantly higher positivity compared to domiciled ones (Fisher's exact test, P = 0.0124). Considering their potential role as reservoirs of L. infantum, it is crucial to conduct further studies to understand the Leishmania spp. circulating among cats in Sobral and to implement measures for reducing their exposure to phlebotomine sand fly vectors in this important focus of leishmaniases.

巴西一家转诊医院的 205 只猫的利什曼原虫感染率（2021-2022 年）

利什曼病是一类被忽视的疾病，在公共卫生领域引起了极大的关注，而巴西是美洲利什曼病的主要流行区。塞阿拉州的索布拉尔市历来是人类和狗内脏利什曼病的高发区，但有关猫利什曼原虫感染的数据却很有限。2021 年 4 月至 2022 年 2 月期间，我们从转诊医院的人群中抽取了 205 只猫，并通过实时 PCR 对其进行了利什曼原虫检测。八只猫（3.9%；95% CI：1.7-7.5%）检测结果呈阳性。其中三只（37.5%）出现了与猫利什曼病相符的临床症状。非户籍猫的阳性率明显高于户籍猫（费雪精确检验，P = 0.0124）。考虑到猫可能是幼年利什曼病的宿主，因此必须开展进一步的研究，以了解索布拉尔地区猫中流行的利什曼病菌属，并采取措施减少猫与这一利什曼病重要集中地的沙蝇病媒的接触。

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).
