Abstract

BACKGROUND

Visceral leishmaniasis (VL) has been increasingly recognized in cats living in areas endemic for the disease. Co-infection with Leishmania infantum and other infectious agents is well established in dogs. However, for cats, data on co-infections with L. infantum and other infectious agents are still sparse. The aim of this study was to identify the prevalence of vector-borne pathogens, Mycoplasma spp., feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) in cats from an area endemic for VL in southeastern Brazil.

RESULTS

Of the 90 cats, eight (8.9%) were infected with Mycoplasma spp., five (5.5%) were FIV- positive and one (1.1%) was FeLV-positive. Co-infection with L. infantum and at least one other infectious agent was found in 9/50 (18.0%; CI: 8.6-31.4%) cats. In Group 1 (cats infected naturally by L. infantum), 4/50 (8.0%) cats were positive for FIV, 4/50 (8%) for Mycoplasma spp. and 1/50 (2.0%) was co-infected with FeLV and Mycoplasma spp. In Group 2 (cats non-infected with L. infantum), 2/40 (5.0%) cats were infected with Mycoplasma spp. and 1/40 (2.5%) was co-infected with FIV and Mycoplasma spp. All cats were negative for Ehrlichia spp., Babesia spp. and Anaplasma platys.

CONCLUSION

A low prevalence of co-infection in Leishmania-infected and non-infected cats was found. Co-infections with Leishmania and vector-borne diseases in cats are not common in this area endemic for VL in Brazil.

摘要

背景

内脏利什曼病（VL）在疾病流行地区的猫中越来越被认识到。犬中已证实利什曼原虫和其他传染性病原体的合并感染。然而，对于猫来说，关于利什曼原虫和其他传染性病原体合并感染的数据仍然很少。本研究的目的是确定巴西东南部 VL 流行地区猫中虫媒病原体、支原体属、猫免疫缺陷病毒（FIV）和猫白血病病毒（FeLV）的流行率。

结果

在 90 只猫中，8 只（8.9%）感染了支原体属，5 只（5.5%）FIV 阳性，1 只（1.1%）FeLV 阳性。在 50 只感染利什曼原虫的猫中，有 9/50（18.0%；95%CI：8.6-31.4%）猫合并感染至少一种其他传染性病原体。在第 1 组（自然感染利什曼原虫的猫）中，4/50（8.0%）猫 FIV 阳性，4/50（8%）猫支原体属阳性，1/50（2.0%）猫 FeLV 和支原体属合并感染。在第 2 组（未感染利什曼原虫的猫）中，40 只猫中有 2/40（5.0%）感染支原体属，1/40（2.5%）FIV 和支原体属合并感染。所有猫均未感染埃立克体属、巴贝斯虫属和无浆体属。
