Abstract

In the last few years, the number of studies on feline hepatozoonosis has increased, but our knowledge on the actual species of Hepatozoon and/or different genotypes affecting felines is still incipient. At least three species, namely Hepatozoon felis, H. canis, and H. silvestris, have been isolated from domestic cats in various countries. Additionally, there are indications that other species and genotypes may affect felines in given geographic areas. This study was carried out to investigate the occurrence of Hepatozoon spp. in cats from Niterói, a municipality within the metropolitan area of Rio de Janeiro, Brazil. Individual blood samples were collected from 28 cats enrolled in a spaying/castration program. DNA was extracted from all samples and subjected to sequencing specific for Hepatozoon spp. DNA of H. felis was found in 21/28 cats (75%), and four genetic polymorphisms never described thus far were detected. This is the first report of H. felis in cats living in the State of Rio de Janeiro, and the present data confirm that H. felis is a species complex encompassing different genotypes circulating within cat populations. Further studies are warranted to investigate whether different genotypes have different biology or pathogenicity for felids.

巴西里约热内卢大都会地区流浪猫中的肝吸虫属

在过去几年中，有关猫科动物肝吸虫病的研究数量有所增加，但我们对猫科动物肝吸虫病的实际种类和/或不同基因型的了解仍处于起步阶段。在不同的国家，从家猫身上至少分离出了三个物种，即猫肝吸虫、犬肝吸虫和硅肺肝吸虫。此外，有迹象表明其他物种和基因型也可能影响特定地理区域的猫科动物。本研究旨在调查巴西里约热内卢大都会区内的尼泰罗伊市猫体内肝吸虫属的发生情况。研究人员从参加绝育/阉割计划的 28 只猫咪身上采集了个体血液样本。在 21/28 只猫（75%）中发现了猫吸虫的 DNA，并检测到迄今为止从未描述过的四种基因多态性。这是首次报告在里约热内卢州生活的猫中发现 H. felis，目前的数据证实 H. felis 是一个物种复合体，包括在猫群中流行的不同基因型。有必要进一步研究不同基因型对猫科动物是否具有不同的生物学特性或致病性。

期刊介绍： Parasite is an international open-access, peer-reviewed, online journal publishing high quality papers on all aspects of human and animal parasitology. Reviews, articles and short notes may be submitted. Fields include, but are not limited to: general, medical and veterinary parasitology; morphology, including ultrastructure; parasite systematics, including entomology, acarology, helminthology and protistology, and molecular analyses; molecular biology and biochemistry; immunology of parasitic diseases; host-parasite relationships; ecology and life history of parasites; epidemiology; therapeutics; new diagnostic tools. All papers in Parasite are published in English. Manuscripts should have a broad interest and must not have been published or submitted elsewhere. No limit is imposed on the length of manuscripts, but they should be concisely written. Papers of limited interest such as case reports, epidemiological studies in punctual areas, isolated new geographical records, and systematic descriptions of single species will generally not be accepted, but might be considered if the authors succeed in demonstrating their interest.
