The objective of this cross-sectional study was to determine the prevalence and intensity of soil-transmitted helminths (STHs) in children aged 0-25 months and to identify the associated risk factors for Ascaris lumbricoides infections. The study was conducted in three villages outside Ile-Ife, Osun state, Nigeria in May/June 2005. Stool samples (369) were processed by formol-ether concentratio...

CONTEXT Ascaris lumbricoides is the second most common intestinal parasite world-wide and, although the infection can be asymptomatic, in some cases it can present with complications, such as acute pancreatitis. CASE REPORT We describe the case of a 37-year-old man, with a history of travelling in Eastern countries who presented with Ascaris lumbricoides-induced acute pancreatitis mimicking a...

Ascaris lumbricoides, the large human roundworm, infects approximately 1,200 million people, with children under the age of 15 being particularly at risk. Monte Carlo quantitative microbial risk analyses were undertaken to estimate median Ascaris infection risks in children under 15 from eating raw carrots irrigated with wastewater. For a tolerable additional disease burden of 10(-5) DALY (disa...

Ascaris lumbricoides and Ascaris suum are widespread parasitic nematodes of humans and pigs respectively. Recent prevalence data suggests that approximately 1.2 billion people are infected. Adult worms exhibit an overdispersed frequency distribution in their hosts and individuals harbouring heavy burdens display associated morbidity. In this review, we describe the parasite, its distribution an...

Sir,?In The Indian Medical Gazette of August of this year. Colonel Clayton Lane, i.M s , has been kind enough to publish a paper and a letter of criticism on my work on the life-history of Ascaris lumbricoides. Colonel Lane's criticism falls naturally under two heads:? I. That the positive proof of the direct transmission of Ascaris lumbricoides without an intermediate host is complete and abso...

Background: Ascariasis and trichuriasis are the most common intestinal geohelminthic diseases, and as such they are significant in terms of clinical and public health. This study was done to determine prevalence, status and geographic distribution patterns for Ascariasis and Trichuriasis. The study was done in the period 1991-2014 in northern Iran using Aregis 9.2 software. Methods: This was...

The parasitic worm Ascaris suum contains the opiate alkaloid morphine as determined by HPLC coupled to electrochemical detection and by gas chromatography/mass spectrometry. The level of this material is 1168 +/- 278 ng/g worm wet weight. Furthermore, Ascaris maintained for 5 days contained a significant amount of morphine, as did their medium, demonstrating their ability to synthesize the opia...

A 65-year-old male was operated for esophageal carcinoma. Transhiatal esophagogastrectomy with jejunostomy feeding tube was done. Orals were started on the 12th postoperative day. The jejunostomy feeding tube was removed on the 20th postoperative day. Immediately after removal of the feeding tube, a 10-12 cm ascaris was seen emerging through the jejunostomy tract. Ascaris lumbricoides can cause...

This study examined the effect of the 2 major means of control of Ascaris lumbricoides--chemotherapy and sanitation. About 200 pre-school Caribbean children living in 3 villages with varying sanitation were studied by quantitative stool examination for the presence of the eggs of helminths. Children with Ascaris eggs were treated with piperazine. Over a 2-year period this procedure was repeated...

OBJECTIVE Eosinophilia and increased serum IgE levels are indicators of atopy; however, other factors can also play a key role, such as intestinal parasitic infections. This study assesses the relationship between total serum IgE, eosinophil count, and anti-Ascaris IgE in individuals with asthma and/or allergic rhinitis. METHODS A cross-sectional study was carried out in adolescents with asth...
