Characterization of Ascaris from Ecuador and Zanzibar [PDF]

, 2014
To shed light on the epidemiology of ascariasis in Ecuador and Zanzibar, 177 adult worms retrieved by chemo-expulsion from either people or pigs were collected, measured and subjected to polymerase chain reaction-restriction fragment length polymorphism (

Molecular Epidemiology of Ascariasis: A Global Perspective on the Transmission Dynamics of Ascaris in People and Pigs [PDF]

, 2014
Background The roundworm Ascaris lumbricoides infects 0.8 billion people worldwide, and Ascaris suum infects innumerable pigs across the globe. The extent of natural cross-transmission of Ascaris between pig and human hosts in different geographical ...

Multi-parallel qPCR provides increased sensitivity and diagnostic breadth for gastrointestinal parasites of humans: field-based inferences on the impact of mass deworming [PDF]

, 2016
BACKGROUND: Although chronic morbidity in humans from soil transmitted helminth (STH) infections can be reduced by anthelmintic treatment, inconsistent diagnostic tools make it difficult to reliably measure the impact of deworming programs and often miss

Comparison of four DNA extraction and three preservation protocols for the molecular detection and quantification of soil-transmitted helminths in stool [PDF]

, 2019
Background : A DNA extraction and preservation protocol that yields sufficient and qualitative DNA is pivotal for the success of any nucleic acid amplification test (NAAT), but it still poses a challenge for soil-transmitted helminths (STHs), including ...

THE LIFE-HISTORY OF ASCARIS LUMBRICOIDES [PDF]

BMJ, 1916
I. In the following three experiments it will be shown that ripe eggs of Ascaris suilla can hatch in the intestine of the pig, that the larvae issuing from these eggs enter the body of the pig and pursue the same course through the body as in the rat and mouse.

The haemoglobins of Ascaris Lumbricoides [PDF]

Proceedings of the Royal Society of London. Series B - Biological Sciences, 1949
The occurrence of distinct haemoglobins in the perienteric fluid and body wall of Ascaris is confirmed and methods described for the extraction and partial purification of the pigments. The absorption spectra of the haemoglobins and their principal derivatives were determined.

Effect of urban vs. rural residence on the association between atopy and wheeze in Latin America: findings from a case-control analysis. [PDF]

, 2014
BACKGROUND: The association between atopy and asthma is attenuated in non-affluent populations, an effect that may be explained by childhood infections such as geohelminths.

Role of the employment status and education of mothers in the prevalence of intestinal parasitic infections in Mexican rural schoolchildren [PDF]

, 2006
<p><b>Background:</b> Intestinal parasitic infections are a public health problem in developing countries such as Mexico. As a result, two governmental programmes have been implemented: a) "National Deworming Campaign" and b ...

Detection of enteric parasite DNA in household and bed dust samples: potential for infection transmission. [PDF]

, 2020
BACKGROUND: Enteric parasites are transmitted in households but few studies have sampled inside households for parasites and none have used sensitive molecular methods.

Identification of human intestinal parasites affecting an asymptomatic peri-urban Argentinian population using multi-parallel quantitative real-time polymerase chain reaction [PDF]

, 2015
Background: In resource-limited countries, stool microscopy is the diagnostic test of choice for intestinal parasites (soil-transmitted helminths and/or intestinal protozoa). However, sensitivity and specificity is low.
