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...

BACKGROUND: Toxocara canis is the most prevalent intestinal roundworm of canid species. OBJECTIVES: This study aims to evaluate the effects of Toxocara canis excretory-secretory antigens (TcES Ag) on modulating the immune system in Experimental Allergic Encephalomyelitis (EAE) model. METHODS: Adult worms of T.canis were collected from dogs to obtain excretory-secretory antigens. Female C57BL/6m...

BACKGROUND Toxocariasis, which is predominantly caused by Toxocara canis (T. canis) infection, is a common zoonotic parasitosis worldwide; however, the status of toxocariasis endemicity in the Republic of the Marshall Islands (RMI) remains unknown. METHODS A seroepidemiological investigation was conducted among 166 primary school children (PSC) aged 7-12 years from the capital area of the RMI...

Most studies from Argentina have focused on toxocariasis as an environmental problem of big cities, and there are no available data about children infection from small or middle-sized cities. In order to assess the prevalence of anti-Toxocara antibodies in infantile population, 206 children from Resistencia, of both sexes, aged 1-14 years old were studied by Elisa testing with E/S T. canis L2 a...

NEMATODE infestations of the eye evoked little or no interest until the middle of the 20th century when Wilder (1950), whilst carrying out a histological survey of 46 cases of pseudogliomata, found nematode larvae or their hyaline capsules in 24, and tissue reactions characteristic of nematode endophthalmitis in the remaining 22. At that time, the larvae found in Wilder's series were believed t...

We aimed to investigate IgG antibody levels specific to Toxocara canis (T. canis), a parasite which subsists in dog's intestine, on serum samples obtained from patients with chronic urticaria (CU) to evaluate effective risk in CU etiopathogenesis. In this study, 73 patients diagnosed with CU and 109 healthy individuals as control group, were included. Various factors such as sex, age, education...

Toxocara canis/cati are parasitic nematodes that resides in the small intestine of dogs, cats and wild carnivores. They are found worldwide. Female worms are approximately 10 cm long and produce hundreds of embrionated eggs per day. Following several weeks in the environment, the embryo matures to the infective larval stage within the egg. It can remain viable for very long periods of time. The...

The frequency of anti-Toxocara spp. antibodies in individuals attended by the Centro de Salud Familiar in the coastal Niebla town, Chile, was related to the host and to environmental factors. IgG anti- Toxocara antibodies were detected with a commercial ELISA kit (SCIMEDX Corporation, USA). Samples with undetermined absorbance values were subjected to an additional ELISA standardized by the Ins...

background : toxocariasis is a zoonotic disease caused by the ascarid of dogs and cats, the main representative of which is a toxocara canis . distribution of the disease is world wide and is more prevalent in children. the present study was carried out in children of kashmir valley, to determine the toxocariasis seropositivity. methods : for the present seroepidemiological study, blood samples...

A 54-year-old man with diabetes mellitus had a blood test and was found to have a blood eosinophilia (1,028/mm 3 ). Liverfunction tests were normal. A hepatic nodule was detected on screening of upper abdominal and renal sonography. Contrastenhanced computed tomography (CT) scan ( Figure 1 ) showed a small, oval, low-attenuating nodule in the right hepatic lobe. CT scans obtained 3, 6, and 10 m...
