| Summary: | Background & objectives: Visceral leishmaniasis (VL) is a fatal zoonotic disease in tropical and sub-tropical countries including Iran. Dogs constitute the main domestic reservoir for VL (kala-azar) in Iran but incidence of the disease in cats from Fars and East Azerbaijan provinces has led to propose them as secondary reservoirs, and possible expansion of the feline role in the transmission of disease. The aim of this study was to evaluate the prevalence of Leishmania infantum infection in stray cats in Kerman City by ELISA and PCR methods.
Methods: In this cross-sectional descriptive study, 60 stray cats were randomly live trapped from different parts of Kerman City during a six month period between March and September 2014. About 3 ml blood samples were drawn from jugular vein of captured cats and a detailed questionnaire about demographic characteristics and clinical status of each cat was recorded by attending veterinarian. The complete blood counts and biochemistry analysis were performed for all cats. Finally collected sera samples were tested by an indirect enzyme-linked immunosorbent assay (ELISA) kit and PCR amplification method.
Results: Prevalence of Leishmania infantum infection was 6.7 and 16.7% by ELISA and PCR assays, respectively. Infection rate was significantly higher in leukopenic cats, which were older than 3 yr.
Interpretation & conclusion: The results of the study indicate that stray cats are at risk of L. infantum infection in Kerman City. Further, studies are required to elucidate the role of cats as potential reservoir host in the epidemiology of VL in endemic regions.
