Toxocariasis is an extensive helminthic infection that leads to visceral larva migrans in humans. A 2.5-year-old girl referred for abdominal mass. She had history of pharyngitis for two weeks. There were no other symptoms. Abdominal examination revealed an irregular solid mass in right lower quadrant (RLQ). Abdominal ultrasonography revealed an echohetrogenic large mass in RLQ, liver, and retro...

A 45-year-old-male who had underlying ulcerative colitis and presented with fever and dry cough. Initially, the patient was considered to have invasive aspergillosis due to a positive galactomannan assay. He was treated with amphotericin B followed by voriconazole. Nevertheless, the patient deteriorated clinically and radiographically. The lung biopsy revealed eosinophilic pneumonia, and ELISA ...

Mongolian gerbils and Wistar rats were inoculated orally with 240 and 2,500 Toxocara cati embryonated eggs, respectively, to evaluate the larval recovery in different tissues and organs, such as the liver, lungs, heart, kidney, and skeletal muscles after 5, 30, 49, 70, and 92 days post-infection (PI). Larval recovery rates were 1.7-30.0% in Mongolian gerbils on days 5-92 PI and 0.2-3.8% in rats...

Human toxocariasis is a widespread parasitic disease caused by ingestion of Toxocara canis or catis larvae or eggs. Parasitic diseases are uncommon in industrialized countries, yet this problem has not disappeared. Parasitic diseases can cause different syndrome (visceral larva migrans, ocular larva migrans) and the clinical features can be confusing. Severe organ involvement affecting the live...

human visceral and ocular toxocariasis can occasionally be a serious or life-threatening condition, especially for children. the diagnosis and confirmation of the disease mostly based upon serological tests. the purpose of the present study was to evaluate somatic antigen with regard to its application in a routine diagnostic laboratory test. using gel-filtration chromatography, fraction no.1 o...

The last large-scale study of the parasite fauna cats and dogs in St. Petersburg was carried out by Prozorov A.M. However, since then, according to sociological surveys, number animals large cities Russia has increased significantly, no new studies on parasitic diseases carnivores have been conducted. As pets increases, so does population. Of particular danger are zoonotic invasions, toxocarias...

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...

background: the diagnosis of toxocariasis heavily depends on immunological tests because the number of parasites is usually few in infected tissues, unless they migrate into an organ such as eye. in general, patients with ocular toxocariasis have serum anti- t canis antibody titres that are significantly lower than those with visceral toxocariasis. objective: to diagnose the asymptomatic toxoca...

Human toxocariasis is usually contracted by exposure to contaminated soil. This disease is rarely transmitted by raw meat or giblets of paratenic animals, such as chickens, lambs, or cows. We present a case of isolated cerebral toxocariasis presumably caused by the consumption of raw duck liver. This 55-year-old woman had sudden-onset hemiparesis of the right leg, eosinophilia of 30%, and marke...

This study was designed to compare the sensitivity and specificity of enzyme linked immunosorbent assay (ELISA) for the serodiagnosis of ocular toxocariasis using Toxocara canis embryonated egg antigen (TEE) and toxocara excretory-secretory or exoantigen (TEX) produced in vitro. TEE and TEX ELISA were comparably sensitive, but TEX ELISA was better able to discriminate between serum samples from...
