Canine toxocariasis in southeast of Iran

Abstract

Toxocariasis is a parasitic zoonosis with worldwide distribution that affects both dogs and cats. A cross-sectional survey was undertaken to study the prevalence and intensity of infection with Toxocara canis in 100 owned dogs, from May to November 2011 in urban areas of Kerman, southeastern of Iran. A total of 100 fecal samples were evaluated by the fecal sedimentation method. A total of 10 dogs were found to be infected with T. canis . The prevalence of T. canis was 10% in owned dogs in Kerman. The age distribution of toxocariasis in dogs less than 6 months old had a higher overall prevalence than those dogs over 6 months of age (P<0.05). There was a significant difference in the prevalence between male (13.2%) and female (7%) dogs (P<0.05). The high prevalence of T. canis infections among canids and contamination of environment by eggs of T. canis may increase the risk of infection for native people. It is imperative to educate the dog-owning population of the potential risks associated with dog toxocariasis. This will allow for the more effective implementation of strategic control programs or minimize zoonotic transmission.
