Toxocariasis is caused by larva of the nematode Toxocara canis or catis. It has been found in a survey that in Southern England about 20% of dogs and cats are infected by the parasite (Woodruff, Thacker, and Shah, 1964). Man becomes infected by ingesting eggs which develop into larvae in his gastro-intestinal tract and then penetrate through the wall invading various organs in the body, most co...

Ocular toxocariasis in adults.

Human infection by toxocara larvae has been thought to be predominantly a disease of young children, but the percentage of the population with antibodies to this nematode worm has recently been shown to increase with age. Although a definite diagnosis of ocular toxocariasis can be made only by identifying the larva histologically, the evidence in three cases presenting with recent uniocular los...

Ocular toxocariasis in schoolchildren.

Ocular toxocariasis in humans is typically a unilateral disease caused by second-stage larvae of the Toxocara species. Serological evidence of widespread infection in humans provides little information on clinical disease. There is only a single previous estimate of the prevalence of ocular toxocariasis (from Alabama). The present survey examined the extent of consultant-diagnosed toxocaral eye...

Toxocariasis in Japan.

Toxocariasis has long been considered a parasitic disease affecting pet owners and children who often play in sandboxes at public parks. Recent cases of this animal-borne infection, however, indicate that its clinical manifestations and etiologies are changing. In this article, we will describe the critical characteristic features of toxocariasis alongside the contributions of Japanese research...
