Sector de Bajo Riesgo. Servicio de Clínica, Hospital Nacional de Pediatría "Prof. Dr. Juan P. Garrahan", Ciudad de Buenos Aires.

Toxocariasis canis or catis is a zoonotic infection disseminated in humans. Human beings can act as non-natural hosts in which the parasite can survive for long periods of time and they become infected by the ingestion of geohelminth eggs. These can be located on the ground, playgrounds and children's games, and are mostly eliminated by dogs or cats. Read More

New insight into the diagnostic cut-off value of serum anti-Toxocara IgG for ocular toxocariasis in uveitis patients.

J Helminthol 2018 Nov 20:1-6. Epub 2018 Nov 20.

Department of Ophthalmology,Faculty of Medicine,Zagazig University,Egypt.

Uveitis is one of the commonest causes of vision loss worldwide and its exact etiology is still not clarified in most patients. The current study is a trial to assess the efficacy of serum anti-Toxocara immunoglobulin G (IgG) by enzyme-linked immunosorbent assay (ELISA) as a diagnostic tool for ocular toxocariasis (OT) and to detect OT prevalence and the associated ocular manifestations in sera of patients with uveitis. One hundred and twelve patients (62 females and 50 males) with uveitis were diagnosed by ophthalmologists, radiologists and rheumatologists according to ocular manifestations, laboratory and radiological investigations.

Clinical and laboratory characteristics of patients with toxocariasis encountered at a tertiary care centre in North India.

Indian J Med Microbiol 2018 Jul-Sep;36(3):432-434

Department of Pediatrics, Postgraduate Institute of Medical Education and Research, Chandigarh, India.

Toxocariasis is a neglected soil-transmitted helminthic infection caused by either Toxocara canis or Toxocara cati where humans get infected by accidental ingestion of embryonated eggs, and the definitive hosts are dogs and cats. This study aims to analyse the clinical and laboratory characteristics of Toxocara-infected patients and assessment of response to standard treatment with review of literature. The clinical details of patients with Toxocara serology positive for IgG antibodies by ELISA in 5 years (2013-2017) were retrospectively analysed. Read More

Molecular characterization of Toxocara spp. eggs isolated from public parks and playgrounds in Shiraz, Iran.

J Helminthol 2018 May 7:1-7. Epub 2018 May 7.

Department of Parasitology and Mycology,School of Medicine,Shiraz University of Medical Sciences,Shiraz,Iran.

Human toxocariasis, a worldwide parasitic disease, is caused by the larval stage of intestinal nematodes of dogs and cats, namely Toxocara canis and Toxocara cati. Human infection occurs by the accidental ingestion of embryonated eggs present in the soil, vegetables or on other contaminated surfaces, as well as via consumption of uncooked paratenic hosts, such as bird meat and giblets.
