Visceral toxocariasis is a neglected zoonosis caused by Toxocara canis larvae in unusual hosts. In dogs, the definitive host, the infection occurs mainly through transplacental and transcolostral transmission. Studies on experimental models have shown that vertical transmission may result from acute infections. Considering that toxocariasis is characterized as a chronic infection, with possible...

We investigated the seroepidemiological, clinical, and laboratory characteristics of patients suspected to have toxocariasis in Gwangju and Jeonnam-province, Korea. In total, 228 specimens were analyzed for anti-Toxocara canis IgG at two university hospitals from 2010 to 2012. The overall seropositive rate was 67.1%, and the seropositive rates among the eosinophilic and non-eosinophilic groups ...

BACKGROUND Human toxocariasis is contained in the list of neglected diseases. The infection occurs after ingestion of embryonated eggs in contaminated soil. The present study was carried out to estimate the extent of soil contamination with Toxocara spp. eggs in the public places. METHODS Soil samples were collected randomly from 41 public places in various parts in and around of Ardabil, Ira...

AIMS To evaluate an antigen capture enzyme linked immunosorbent assay (ELISA) which detects a carbohydrate epitope on the excretory-secretory (ES) antigens of Toxocara canis in clinical practice. METHODS Serum specimens from healthy adults, patients with acute visceral larva migrans, ocular and inactive toxocariasis, and with other helminth infections were examined by two site antigen capture...

New information indicates that toxocariasis is the most common human parasitic worm infection in the United States, affecting millions of Americans living in poverty. The infection is also highly prevalent in many developing countries and its global importance may be greatly underestimated. Toxocariasis results from zoonotic transmission of the roundworms, Toxocara canis and T. cati from dogs a...

A dot enzyme-linked immunosorbent assay (dot-ELISA) was standardized using excretory-secretory antigens of Toxocara canis for the rapid immunodiagnosis of human toxocariasis. Thirty patients with clinical signs of toxocariasis, 20 cases with other parasitic diseases, and 40 healthy subjects were tested. A total of 0.2 ng of antigen per dot, serum dilution of 1:160 and dilution conjugate of 1:10...

UNLABELLED The aim of the current study was to examine the relationship between asthma and toxocariasis. MATERIAL AND METHODS We have studied 76 patients with asthma and 88 controls (without asthma) aged 5-16 years. An ELISA test based on the detection of anti-Toxocara canis (E/S antigen) serum immunoglobulin G (IgG) and E (IgE) was done in both groups. Ordinary allergens and E/S antigen of T...

BACKGROUND Toxocariasis is an important disease caused by the larvae of parasitic worms such as Toxocara canis and T. cati. Public parks can be the source of toxocariasis for small children. This survey was conducted to determine the prevalence of Toxocara spp. ova in parks of Mashhad and Khaf northeastern Iran. METHODS In this descriptive cross-sectional study, performed in November 2011 to ...

patients and methods serum samples of 100 patients with hypereosinophilia (> 10%) and 100 normal individuals (without eosinophilia) were collected. demographic information of the participants was recorded in a predesigned questionnaire during sample collection. anti-toxocara antibodies in the subjects’ serum were evaluated by an elisa. results in the hypereosinophilic patients, 54 (54%) were ma...
