Toxocara canis is an intestinal nematode affecting dogs and cats that causes human infestations by ingestion of embryonated eggs excreted in dogs' faeces. Humans are transport hosts, in whom the larvae do not develop to adult worms, but may migrate to various tissues and organs, and survive for several years, giving rise to several clinical symptoms, which include allergy-like presentations. We...

We report the results of a joint human-animal health investigation in a Dene community in northern Saskatchewan, where residents harvest wildlife (including moose, bear, elk, and fish), live in close contact with free roaming dogs, and lack access to permanent veterinary services. Fecal analysis of owned and free-roaming dogs over two consecutive years (N = 92, 103) identified several parasites...

A 16-year-old girl developed a cough, hypereosinophilia (absolute eosinophil count: 32000/mm3), hypergammaglobulinemia, and multiple noncavitary pulmonary nodules 1 month after having ingested an earthworm on a dare. Spirometry revealed moderate restriction and reduced gas diffusion. Parabronchial biopsy demonstrated eosinophilic organizing pneumonitis with multiple eosinophilic microabscesses,...

Contact with the soil, fomites or hands contaminated with the animals’ feces favors accidental human infection either through ingestion of Toxocara canis embryonic eggs, resulting in Visceral Larva Migrans (VLM) syndrome (Coelho et al., 2001), or through percutaneous penetration of Ancylostoma caninum and Ancylostoma braziliense infective larvae, causing Cutaneous Larva Migrans (CLM) Syndrome (...

An investigation to determine the prevalence and distribution of gastrointestinal roundworms in calves in Sokoto metropolis was carried out. A total of 216 faecal samples from calves were examined using Modified McMaster technique for morphological egg differentiation and count of worm-egg per gram of faeces of the sampled calves. Positive samples were cultured to differentiate between morpholo...

The present study has been conducted for the detection of gastrointestinal parasites isolated from cats and dogs in Basrah province November 2018 to January 2019. One hundred fecal samples were collected dogs. Samples submitted parasite’s lab college veterinary medicine university. diagnoses by direct microscopic examination concentration methods. Gastrointestinal cat identified this were: Toxa...

Eggs of Toxocara cati were found in the feces of Didelphis albiventris from a peridomestic urban environment in Brazil. Negative fecal tests following short-term captivity of the opossums, as well as the absence of ascaridids during necropsy, suggest the occurrence of pseudoparasitism. Implications of the findings for the epidemiology of toxocariasis are discussed.
