The aim of this note was to record for the first time the recovery of Toxocara canis larvae from tissues and organs of Rattus norvegicus (Berkenhout, 1769), Wistar strain, until the 60th day after experimental infection. Rats were orally infected with embryonated T. canis eggs, killed on days 3, 5, 8, 10, 15, 30, and 60 after inoculation and larvae were recovered from liver, lungs, kidneys, bra...

background: toxocariasis is an important disease caused by the larvae of parasitic worms such as toxocara canis and t. cati . public parks can be the source of toxocariasis for small children. this survey was conducted to de-termine the prevalence of toxocara spp. ova in parks of mashhad and khaf northeastern iran. methods: in this descriptive cross-sectional study, performed in november 2011 t...

The aim of this study is to ascertain the relationship between ingestion of raw cow liver and Toxocara canis infection. A total of 150 apparently healthy adults were divided into 2 groups; 1 group consisted of 86 adults with positive results of Toxocara ELISA, and the other group of 64 adults with negative results. One researcher collected the history of ingestion of raw cow liver within 1 year...

In the present study, the initial developmental stage of Toxocara canis eggs and larvae, and number of recovered larvae from BALB/c mouse-infected organs are described. In vitro culture of T. canis detects the frequencies of interphasic, mitotic and embryonated eggs only within a 7-day period. Analysis by egg counting was carried out for 32 days. The results showed that at 7 days after cultivat...

PURPOSE Increased seropositivity for Toxoplasma gondii and Toxocara canis have been observed in epileptic patients. Our aim is to determine whether there is any relationship between these agents and epilepsy in our cryptogenic epilepsy group. MATERIAL AND METHODS We studied specific IgG antibodies against T. gondii and T. canis in 100 cryptogenic epileptic patients and 50 healthy volunteers t...

We present the case of a 23-year-old woman with cerebrospinal fluid eosinophilia and myelopathy caused by Toxocara canis and describe the clinical and thoracic MR findings. An enhancing thoracic spinal cord lesion which was shown on MR resolved after an interval of 140 days with partial resolution of the patient's symptoms.

Toxocariasis is a soil-transmitted helminthozoonosis due to infection of humans by larvae of Toxocara canis. The disease could produce cognitive and behavioral disturbances especially in children. Meanwhile, in our modern era, the incidence of immunosuppression has been progressively increasing due to increased incidence of malignancy as well as increased use of immunosuppressive agents. The pr...

BACKGROUND We tried to investigate the hair contamination of pet dogs and farm sheepdog with Toxocara eggs in terms of the different sex and age groups in north-west of Iran (Urmia and its suburbs). METHODS Hair samples were collected from a total of 138 pet and farm sheepdogs from November 2008 to June 2009 in Urmia City and the suburb (West Azerbaijan-Iran) and examined for the presence of ...

OBJECTIVE Human toxocariasis is a zoonotic infection caused by the larval stages of Toxocara canis (T. canis) and less frequently Toxocara cati (T. cati). A relationship between toxocariasis and epilepsy has been hypothesized. We conducted a systematic review and a meta-analysis of available data to evaluate the strength of association between epilepsy and Toxocara spp. seropositivity and to pr...

Vertical starch gel electrophoresis and trefoil immunodiffusion were used to study the systematics of some ascaridoid nematodes. Within the Ascarididae, the time scale of divergence was too great for intergeneric electrophoretic comparisons. Congeneric electrophoretic comparisons of Baylisascaris procyonis (host--raccoon) versus Baylisascaris transfuga (host--black bear), and Toxocara canis (ho...
