Infectious diseases caused by soil-transmitted helminths (STHs) are important diseases of humans, which affect about one third of the world’s population. Examination of soil can be used to estimate the risk of STH infection in humans. We carried out this survey to clarify the current status of soil contamination by parasite eggs and to assess the risk of STH infection. During survey periods, we...

Toxocara canis is one of the most common gastrointestinal helminthes of dogs. Humans can become infected through ingestion of infective eggs. Infection often causes few symptoms but in rare cases blindness can occur. It is generally accepted that human infection is caused as a result of direct contact with contaminated soil. However, recently, the eggs of Toxocara spp. have been found in the ha...

Toxocara spp., the common roundworms of domestic and wild animals, are the causative agents of larval toxocarosis in humans. The migration of Toxocara larvae in men causes clinical syndrome, called larva migrans visceralis or larva migrans ocularis. The objective of the present work was to investigate the prevalence of toxocarosis in dogs, red foxes (Vulpes vulpes), and small mammals in the Slo...

Human toxocariasis (HT) is a zoonotic disease caused by infection with the larval stage of Toxocara canis, the intestinal roundworm of dogs. Infection can be associated with a wide clinical spectrum varying from asymptomatic to severe organ injury. While the incidence of symptomatic human toxocariasis appears to be low, infection of the human population is widespread. In Cuba, a clear overview ...

The objective of this study was to evaluate the relationship between toxocariasis frequency and demographic, environmental, sanitary variables, eosinophylia, and other intestinal parasites in a rural population of Argentina. Serological examination of 100 individuals was carried out by using ELISA technique for the detection of anti-toxocara antibodies. Eosinophiles in peripheral blood, presenc...

Dogs on the Galapagos Islands are a unique population created by isolation from the mainland and regulations prohibiting further importation. The effect of infectious agents of these domestic dogs on the indigenous fauna is largely unknown. The purpose of this study was to determine the prevalence of intestinal parasites in dogs on the Galapagos Islands. Fecal samples were collected from 97 dog...

A survey was conducted to determine the prevalence of gastrointestinal parasitism in crossbred and local cattle, Sylhet division, Bangladesh. Fecal samples were collected randomly from 288 local and 144 crossbred cattle of four representative areas in three following seasons. The effects of season and age were tested in both local and crossbred cattle. Frequency of trematodes and nematodes infe...

INTRODUCTION: The impact of gestational toxocariasis is an understudied topic on female reproductive health. We estimated anti-Toxocara IgG prevalence among pregnant women in Brasília, Brazil, and investigated the association of the infection with history of abortion and contact with pets. METHODS: Infection was diagnosed using ELISA with excretory/secretory antigens. Participant information ...
