Background and Aims: Toxocariasis is a zoonotic parasitic disease with worldwide distribution caused by the larval stage of ascaridoid nematodes of dogs (Toxocara canis) and cats (Toxocara cati). The study was accomplished to determine the sequence variation in ITS2 and COX1 genes within isolates of Toxocara canis. Materials and Methods: Two hundred Stool samples were collected randomly from d...

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...

Background: Toxocara infection is one of the most neglected tropical diseases that has remained undiagnosed in developing countries. The disease leads to many signs and symptoms such as fever, coughing or wheezing, belly pain, hepatomegaly, loss appetite, rash, lymphadenopathy, red painful eyes, strabismus, blurred cloudy vision, like. Objective: present study aimed at investigating seroprevale...

background: the objective of the present research was to determine the frequency of toxocara spp. eggs in soil samples of public parks, in the city of tehran, iran. methods: a total of 600 soil samples were taken from 120 parks between aprils to november, 2008. soil samples were collected from 5 distinct sites in the parks. the samples were washed with saline solution and the collected sediment...

canids are reservoir for some zoonoses helminthic disease. they are one of main public health problem. theaim of this study was to ascertain frequency of gastrointestinal helminthic infection of stray dogs in zabol city,southeaster of iran. in this descriptive study, 30 stray dogs were euthanized, intestine was removed by necropsy.then, the intestines was opened by scalpel and their contents pa...

BACKGROUND Toxocariasis is a zoonotic disease that poses a threat to public health worldwide. This disease primarily affects children and is caused by the presence in the digestive tract of a common roundworm of dogs, Toxocara canis, or cats, Toxocara cati. Toxocara is responsible for the presentation of various syndromes in humans depending on the affected organs. METHODS In this study, the ...

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...

BACKGROUND The purpose of this case report is to describe clinical and angiographic findings of retinal vasculitis in acute Toxocara canis neuroretinitis associated with systemic infection. FINDINGS A 16-year-old male presented with a 1 week history of left eye pain, floaters, and decreased visual acuity. Ocular examination was consistent with neuroretinitis and retinal vasculitis. Fluorescei...

Hepatic toxocariasis is visceral larva migrans caused by Toxocara. We report a case of hepatic toxocariasis detected incidentally during a health checkup. The patient had elevated levels of eosinophils, total IgE, and anti-Toxocara IgG antibodies. On contrast-enhanced computed tomography (CT) imaging he had a single, 2.16 cm, oval, ill-defined, low-attenuation hepatic nodule which was best appr...

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...
