Toxocariasis is currently considered an important zoonosis in many countries and is usually attributed to larvae of Toxocara canis Werner, 1782 but less frequently, T. cat. This study attempts to compare the migration routes followed by T. canis and Toxocara cati (Schrank, 1788) in Rattus norvegicus Berkenhout, 1769 and to determine the percentage of larvae recovered in each organ of experiment...

Human toxocariasis is commonly seen in places where stray and Toxocara canis-infected dog population is high. There is a strong correlation between frequency of Toxocara infection, life style, and infection risk. Institutionalization of mental retarded patients increases to risk of toxocariasis. In this study, we aimed at investigating the frequency of Toxocara infection among children with men...

Seventeen specimens of carnivores the families Felidae (Puma concolor and Leopardus geoffroyi) Canidae (Lycalopex culpaeus) were collected in different localities Nahuel Huapi National Park (Argentina) from August 2005 to May 2018. The processed by necropsy, ascaridid parasites obtained only L. culpaeus. Morphological analysis indicates all belong Toxocara canis, specific identification was con...

Cardiac involvement in hypereosinophilia is rare; when present, it manifests as ventricular thickening, usually with fibrous tissue and mural thrombosis. We present a case of a 57-year-old man with an abnormal right ventricular apex with eosinophilia, which was caused by Toxocara canis infection.

Using STAT6(-/-) BALB/c mice, we have analyzed the role of STAT6-induced Th2 response in determining the outcome of experimental toxocariasis caused by embryonated eggs of the helminth parasite Toxocara canis. Following T. canis infection wild-type BALB/c mice developed a strong Th2-like response, produced high levels of IgG1, IgE, and IL-4, recruited alternatively activated macrophages, and di...

Introduction: Human Toxocariasis is a zoonotic helminthic infection caused by migration of larval stage of Toxocara canis and Toxocara catti (T.canis and T.catti) that mainly affects children. The purpose of this study was to evaluate the frequency of anti-Toxocara antibody IgG in serums of 5-15-years-old children referred to Bandar Abbas and rural parts of nearby health centers. Along with Ant...

A total of 111 samples (43 faeces and 79 gastrointestinal tracts) of 14 wild carnivore species from 12 Argentine provinces were analyzed. Helminth eggs were identified in 73% of the faecal samples and adult worms were recovered from 81% of the gastrointestinal tracts. We found 19 helminth species. Among the most frequent findings were parasites of domestic carnivores, namely Toxocara canis, Tox...

This study was designed to compare the sensitivity and specificity of enzyme linked immunosorbent assay (ELISA) for the serodiagnosis of ocular toxocariasis using Toxocara canis embryonated egg antigen (TEE) and toxocara excretory-secretory or exoantigen (TEX) produced in vitro. TEE and TEX ELISA were comparably sensitive, but TEX ELISA was better able to discriminate between serum samples from...

Demographic characteristics associated with human Toxocara canis infection in children aged one to 11 years were investigated using data from the Health and Nutrition Examination Survey of 1971 to 1973. An enzyme-linked immunosorbent assay with larval stage antigen was used to measure the concentration of antibodies to T. canis in 1,409 available sera. From 4.6 to 7.3% of the children in differ...
