Feces of stray cat are potential sources of gastrointestinal parasites and play a crucial role in spreading and transmitting parasite eggs, larvae, and oocysts through contamination of soil, food, or water. In this study, we investigated the prevalence of Toxocara spp. infection in stray cats in Ahvaz city, southwest Iran. Eggs of Toxocara spp. in feces of stray cats were detected by the sucros...

PURPOSE To investigate the role of Toxocara canis in posterior uveitis of undetermined origin. DESIGN Retrospective case-study. METHODS Paired ocular fluid (47 aqueous humor [AH] and two vitreous fluids) and serum samples of 37 adults and 12 children with undetermined posterior uveitis were retrospectively analyzed for intraocular IgG antibody production against Toxocara canis by enzyme-lin...

Seroprevalence data illustrate that human exposure to Toxocara is frequent. Environmental contamination with Toxocara spp. eggs is assumed to be the best indicator of human exposure, but increased risk of exposure has also been associated with many other factors. Reported associations are inconsistent, however, and there is still ambiguity regarding the factors driving the onset of Toxocara ant...

Toxocariasis is a parasitic zoonose caused by the infection of larval nematode Toxocara species. A total of 285 soil samples from January to March 2009 in 18 public parks were collected to test for soil contamination with Toxocara eggs. Soil samples were investigated for the present of Toxocara eggs using sucrose flotation method. Distribution of Toxocara spp. eggs in samples collected from pub...

Visceral and cutaneous larva migrans are parasitic zoonoses caused by the infection of larval nematodes Toxocara sp. and Ancylostoma sp. respectively. The objective of this study was to investigate the contamination by Toxocara sp. eggs and Ancylostoma sp. eggs and larva of soil samples collected from public parks and children's playground areas in state of Minas Gerais, Brazil, using both Baer...

Human infections by Toxocara canis or Toxocara cati larvae are frequent and have a cosmopolitan distribution resulting, sometimes, in the occurrence of visceral larva migrans syndrome. Ingestion of embryonated Toxocara eggs, present in the superficial layers of the soil, represents the most important way for human infection by these ascarids. Therefore, contact with contaminated soil is conside...

Human toxocariasis is a zoonotic infection caused by the larval stage of Toxocara species. A relationship between toxocariasis and multiple sclerosis has been hypothesized. In this study, we aimed at investigating the frequency of Toxocara infection among multiple sclerosis patients and the epidemiological factors associated with disease. Sixty-eight patients with multiple sclerosis and 70 heal...

An investigation was carried out to determine whether a relationship existed between infections with Toxoplasma gondii and Toxocara canis. Antibodies were sought by the toxoplasma dye test and the toxocara skin sensitivity test. Sixty-seven patients were examined in the United Kingdom; 38 had positive toxoplasma dye tests, two of these being toxocara-positive; and 29 had negative dye tests, six...

BACKGROUND Toxocara canis and T. cati are parasites of dogs and cats, respectively, that infect humans and cause human toxocariasis. Infection may cause asthma-like symptoms but is often asymptomatic and is associated with a marked eosinophilia. Previous epidemiological studies indicate that T. canis infection may be associated with the development of atopy and asthma. OBJECTIVES To investiga...

PURPOSE This study evaluated the prevalence of ocular toxocariasis (OT) in patients with uveitis of unknown etiology who visited a tertiary hospital in South Korea and assessed the success of serum anti-Toxocara immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) as a diagnostic test for OT. METHODS The records of consecutive patients with intraocular inflammation of unknown etio...
