Two brothers with visceral larva migrans caused by Trichuris vulpis were diagnosed after they had been investigated for an eosinophilia. Both patients were almost asymptomatic. The diagnosis of visceral larva migrans was based on the results of immunoelectrophoretic studies and no liver biopsy was performed. After administration of thiabendazole, the number of eosinophils and serum total IgE le...

Two unrelated Bangladeshi women, a 61-year-old with chronic diarrhea, lower abdominal pain, poor appetite, and weight loss for two years with normal physical exam and unremarkable laboratory tests; and a 58-year-old with epigastric pain, bloating, poor appetite, weight loss for three months, and iron-defi ciency anemia, presented for colonoscopy. Colonoscopy revealed two white-colored worms in ...

School children from 3 primary and 2 secondary schools in Sarawak were examined for the presence of gastrointestinal helminths. One primary school and 1 secondary school were located in a town (Serian), the other primary and secondary schools were in the countryside outside Serian. The intestinal helminths detected were Ascaris lumbricoides, Trichuris trichiura, Enterobius vermicularis and hook...

Dysentery due to infestation with the whipworm, Trichuris trichiura, is common among underprivileged children living in Cape Town. Chronic blood loss and a diet deficient in iron leads to profound anaemia and it is not unusual for young children with this infestation to present in cardiac failure. While temporary correction of anaemia and treatment ofiron deficiency are readily achieved, eradic...

We present a human infection with the canine whipworm, Trichuris vulpis, in a child suffering from rhinitis with a diagnosis of rhinitis. T. vulpis eggs resemble those of T. trichiura but they can be differentiated based on their morphological features and egg size, using micrometry with an ocular micrometer. T. vulpis eggs measured an average of 90 µm by 44 µm (range 86-99 µm by 38-47 µm). Pre...

The mouse whipworm Trichuris muris has long been used as a tractable model of human Trichuriasis. Here we look back at the history of T. muris research; from the definition of the species and determination of its life cycle, through to the complex immune responses that we study today. We highlight the key research papers that have developed our understanding of immune responses to this parasite...

This study investigated the gastrointestinal parasitism by helminths and protozoa in sheep (Ovis aries) Santa Inês breed, municipality of Lajes, Rio Grande do Norte. Monthly, from April 2005 to August 2007, stool samples were collected from two tracer lambs in the first day of the experiment and performed a necropsy of these animals in 44th day. A total of 64 lambs were sampled, but only 62 lam...

The two geohelminths, Ascaris lumbricoides and Trichuris trichiura, infect more than a billion people worldwide but are only reported sporadically in the developed part of the world. In contrast, the closely related species A. suum and T. suis in pigs have a truly global distribution, with infected pigs found in most production systems. In areas where pigs and humans live in close proximity or ...

OBJECTIVE To find the occurrence pattern and prevalence of the soil transmitted helminths in women of child bearing age group. METHODS AND MATERIALS The study was conducted in Jiri , an area of Dolakha district at the altitude of 2100 meter from sea level. The faecal sample of 478 women of childbearing age (15 to 45 years) were taken randomly and examined for the ova of soil transmitted helia...
