“…The results indicate that high levels of helminthic parasite infection exist in well-cared-for dogs in Kingston, Jamaica. Comparison of our data with those obtained from other similar coprological studies of canine populations (Table HI) indicates that the prevalence of hookworm infections in well-cared-for dogs in Jamaica is similar to that encountered in other dog populations in tropical and semi-tropical areas in the Americas (THOMPSON et al, 1986;VAUGHN & JORDAN, 1960; WILLIAMS & MENNING, 1961), and higher than that seen in less well-cared-for animals in some more northern zones studied (DUBIN et al, 1975;JACOBS & PEGG, 1976). However the observed prevalence is smaller than that recorded for stray dogs in Nigeria (DADA & BELINO, 1979) and elsewhere in Kingston (95-100%) (BUNDY et al, 1981).…”

This study investigates the level of helminthic infestation in better-cared-for dogs in a middle-class community in suburban Kingston. A canine zoographic study was conducted, and fresh faecal deposits were collected and analysed for helminth life-cycle stages. The survey indicated that 73% (n=93) of households in the study area owned one dog or more (mean=1·4). Resident's attitudes towards canine management suggested that the dog population was, in general, restricted to the residential estate, and most owners claimed to have dewormed their dogs at least as young animals. Of 141 faecal specimens, 58% contained eggs or larvae of one or more of eight helminths: Uncinaria stenocephala (26%), Ancylostoma sp. (23%), Trichuris vulpis (9%), Toxocara canis (8%), Spirocerca lupi (6%), Strongyloides sp. (6%), Apophallus sp. (4%) and taeniids (1%). There was a high level of multiple infection in the host animals, with approximately one fifth of the infected samples containing three or more helminth types. Infection intensity was apparently low, but some dogs harboured heavy worm loads.

“…Studies on the prevalence of Toxocara and other intestinal parasites of dogs in various areas of the USA and other parts of the world have shown that a prevalence of 7% for T. canis infection among a population of dogs should be considered hazardous to children. This is because of the daily shedding of many thousands of Toxocara eggs into the environment, leading to contamination and thereby exposing children to accidental ingestion of the eggs as a result of their play habits (Hindman & Baker, 1936; Ehrenford, 1957; Vaughn & Jordan, 1960; Williams & Menning, 1961).…”

A study on the prevalence and intensity of Toxocara canis (Werner, 1782) in dogs was carried out in Ile-Ife, Nigeria. Faecal samples were collected from 269 dogs between January and December 2004, processed by the Kato-Katz technique and then examined for T. canis eggs. The prevalence of T. canis obtained was 33.8%. The intensity of infection, measured as mean egg count per gram of faeces ( +/- SEM) was 393.8 +/- 83.4. The prevalence and intensity of T. canis in dogs aged 0-6 months were significantly higher (P < 0.05) than older age groups. The prevalence and intensity of T. canis infection were significantly higher in males than in female dogs (P < 0.05). Since T. canis is known to cause visceral larva migrans (VLM) in young children, there is the possibility that the high prevalence of T. canis infection obtained in this study might constitute an important risk factor for transmission to humans. Therefore, there is the need to educate the residents of Ile-Ife on the danger of close association of their children with household pets.

“…Older dogs can harbor adult worms that do not lay eggs. 13 Toxocara eggs are found in the soil throughout tropical and temperate climate regions. In the United States and Western Europe, soil from parks and public areas has been found to carry a contamination rate of 10% to 30%.…”

Parasitic infections may damage various ocular tissues, thereby causing visual dysfunction. In 1950, Wilder described the first case in which larval forms of nematodal intestinal roundworms (Ascaridoidea: Ascaris, Toxocara, Ancylostoma, Necator, and Strongyloides) were implicated as a cause of intraocular disease. This review focuses on two disorders associated with parasitic infections: ocular toxocariasis and diffuse unilateral subacute neuroretinitis.
