conclusions through these results, the applicability of the used extracts in the control of eggs and/or larvae of t. canis and a. caninum is suggested. however, it is worth mentioning that further studies should be performed with the species e. edulis, m. glomerata and m. laevigata, using different extracts, new concentrations, and in vivo studies, in order to ensure further clarification on th...

We have studied functional alteration of immunocytes in mice following inoculation of Toxocara canis second stage larvae. Results indicated depression of lymphocyte blastogenesis in response to concanavalin-A, phytohemagglutinin and allogeneic non B-cells; however, B-cell polyclonal activation was not affected as indicated by the production of total IgG. In contrast, frequency of antibody ...

The objective of this study was to determine seroprevalence and identify risk factors associated with Toxocara canis infection. A clinical and epidemiological questionnaire and body mass index were used to assess the risk factors associated with human toxocariasis in 108 children with an age range of 2-16 years. Antibodies against Toxocara canis were detected using an ELISA test kit. Chi-square...

BACKGROUND & PURPOSE Humans act as an intermediate host for Toxocara canis and Toxocara cati. Toxocara may be an important risk factor for asthma in humans. The aim of the present study was to evaluate immunoglobulin G (IgG) anti-Toxocara canis antibody, using enzyme-linked immunosorbent assay (ELISA) in asthmatic patients (aged 5-15 years), referring to a clinic of pulmonary diseases in Arak, ...

The existence of Toxocara canis-specific antibodies has recently been reported in patients with atopic myelitis. Here, we report the case of a 35-year-old male patient admitted with a chief complaint of right lower limb hypoesthesia lasting for a month. The patient was diagnosed with eosinophilic pneumonia 3 months ago, and a spine MRI revealed the presence of myelitis in the cervicothoracic co...

PURPOSE To investigate the role of Toxocara canis in posterior uveitis of undetermined origin. DESIGN Retrospective case-study. METHODS Paired ocular fluid (47 aqueous humor [AH] and two vitreous fluids) and serum samples of 37 adults and 12 children with undetermined posterior uveitis were retrospectively analyzed for intraocular IgG antibody production against Toxocara canis by enzyme-lin...

INTRODUCTION Toxocara canis is an ascarid parasite of the small intestine of dogs that causes visceral larva migrans in humans. METHODS With the aim of demonstrating the effectiveness of the fungus Pochonia chlamydosporia on Toxocara canis eggs under laboratory conditions, a trial was set up in Petri dishes with 2% agar-water. RESULTS There was ovicidal activity of 43.8% (p < 0.01) in the t...

An ocular Toxocara canis infection is reported for the first time in Vietnam. A 34-year-old man residing in a village of Son La Province, North Vietnam, visited the National Eye Hospital (NEH) in August 2011. He felt a bulge-sticking pain in his left eye and loss of vision occurred over 3 months before visiting the hospital. The eye examination in the hospital showed damage of the left eye, red...

The present study was conducted to find out the prevalence of Toxocara canis in Lahore, Pakistan and its effect on hemogram in dogs. For this purpose a total of 200 fecal and blood samples from dogs (n=100 stray dogs, n=100 pet dogs) were collected and examined. The results revealed the prevalence of Toxocara canis as 49% and 30% in stray and pet dogs, respectively. A significant decrease was r...
