Background: Human toxocariosis is a parasitic zoonosis caused by larval forms of the genus Toxocara. The eggs hatch after being ingested, penetrate the intestinal wall and migrate via the blood stream through to the liver, hence spread to other organs. Erratic larval migration by the different soft tissues in humans, generates four syndromes, Visceral Larva Migrans, Ocular Larva Migrans, neurot...

mopolitan roundworms that infect dogs, especially puppies, and cats. T. canis infection in humans occurs by ingestion of the embryonic eggs, which are shed in the feces of infected dogs. Toxocariasis is manifested in three different syndromes: visceral larva migrans (VLM), ocular larva migrans (OLM), and covert toxocariasis (1, 2). VLM is usually a disease of children 1 to 6 year old, and it ma...

ABSTRACT Aim: One of the main diagnostic problems of conventional polymerase chain reaction (PCR) is indiscrimination of low parasitic loads in soil samples. The aim of this study is to determine the genetic diversity and identification of Toxocara spp. from public areas soil inferred by loop-mediated isothermal amplification (LAMP) assay. MATERIALS AND METHODS A total of 180 soil samples wer...

Background: The present study was carried out on the human population of Kashmir valley to evaluate the status of the biochemical parameters of infected population. Materials and Methods: Blood samples were collected from 514 individuals, 298 (57.97%) males and 216 (42.02%) females, 187 (36.38%) were found sero-positive for human toxocariasis. Results: Alkaline phosphatase level was found highe...

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...

With the aim of estimating the incidence of infection by Toxocara among residents in the outskirts of Campinas (State of São Paulo, Brazil) two serological surveys, using ELISA anti-Toxocara tests, were performed in January 1999 and January 2000, involving, respectively, 138 and 115 individuals, 75 of which examined in both occasions. Among this group 67 individuals did not show the presence of...

Toxocariasis is one of the causes of pulmonary eosinophilic infiltrate that is increasing in Korea. This study was designed to identify the prevalence of toxocara seropositivity in patients with unexplained pulmonary patchy infiltrate and to evaluate associated factors. We evaluated 102 patients with unexplained pulmonary patchy infiltrate on chest computed tomography (CT) scan. As a control se...

Visceral larva migrans syndrome by Toxocara affects mainly children between 2 and 5 years of age, it is generally asymptomatic, and the seroprevalence varies from 3 to 86% in different countries. A total of 399 schoolchildren from 14 public schools of the Butantã region, São Paulo city, Brazil, were evaluated by Toxocara serology (enzyme-linked immunosorbent assay). Epidemiological data to the ...

Soil can be a source of human infection by many zoonotic helminth species including Echinococcus multilocularis and Toxocara spp. The prevention of alveolar echinococcosis could be greatly improved through the identification of at-risk areas. Yet very few data are available about the detection of E. multilocularis in soil, while more studies have been reported for Toxocara spp. Identification o...
