Ascaris lumbricoides is one of the most common human helminthic diseases worldwide. On ultrasound, it is seen as linear non-shadowing echogenic structures with target appearance in cross section, and the live worm may show writhing movements in real time. On barium meal follow through, it appears as radiolucent tubular filling defects within the bowel lumen. Though not sensitive, direct real-ti...

Infection with intestinal helminths results in immunological changes that influence co-infections, and might influence fecundity by inducing immunological states affecting conception and pregnancy. We investigated associations between intestinal helminths and fertility in women, using 9 years of longitudinal data from 986 Bolivian forager-horticulturalists, experiencing natural fertility and 70...

Children putatively immune to the large roundworm Ascaris lumbricoides were identified in an area of Nigeria where infection is hyperendemic. Immunity was associated with higher levels of serum ferritin, C-reactive protein, and eosinophil cationic protein, indicating ongoing acute phase or inflammatory processes. In contrast, children who were susceptible to the infection had little serological...

BACKGROUND Understanding the prevalence of soil-transmitted helminth infections is necessary to plan control strategies and focus on highly endemic regions for preventive chemotherapy and improved sanitation facilities. India is known to be endemic for soil-transmitted helminth infections. METHODS To understand the prevalence, spatial distribution and identify high-risk zones, a systematic se...

The research was carried out to determine the incidence of intestinal nematode infection in primary school children in three primary schools in Ezza North Local Government Area, Ebonyi State. Eight hundred feacal samples were examined using direct smear method. Out of the number examined, 204 (25.5%,), comprising 395 males (27.6%) and 405 (23.5%) females were infected with intestinal nematodes ...

Introduction Ascariasis is one of the most common intestinal nematode infections caused by Ascaris lumbricoides, especially in the tropics and subtropics where warm, wet climates favor year-round transmission of infection(1). Humans become infected by ingesting infective ascaris eggs in contaminated food, water or from hands that have become faecally contaminated and can cause reduced physical ...

Background: We wanted to investigate the relationship between intestinal parasitic infection and anaemic patients. Methods: stool samples were examined for Protozoa and Helminths infection by routine microscopy and blood samples were performed using the electronic cell counter Coulter. Results: Out of 592 samples 277(46.79%) were positive among them Entamoeba histolytica 80(28%), Ancylostoma du...

This study relates to a method for evaluating the degradation efficiency of Ascaris lumbricoides eggs through a Fenton reaction, using hydrogen peroxide (H2O2) at 100, 250, and 500 mg/L, ferrous sulfate (FeSO4) at 458 mg/L Fe(2+) and pH values of 3, 4.5, and 6. The experiments were conducted according to a 3(2) experimental design, with 1:1, 3:1, and 5:1 (H2O2/Fe(2+)) molar ratios. The oxidatio...

This review highlights advances made since 2004 in understanding the epidemiology of infection and the interactions between Ascaris lumbricoides and other concurrent infections. As water scarcity increases, untreated wastewater is increasingly used to irrigate crops, thus increasing the risk of transmission. New methods to detect and inactivate Ascaris eggs in water, soil and food are described...

To investigate the potential immunomodulatory effects of concurrent ascariasis on the cytokine response to a live oral vaccine, we measured cytokine responses to cholera toxin B subunit (CT-B) following vaccination with the live oral cholera vaccine CVD 103-HgR in Ascaris lumbricoides-infected subjects randomized in a double-blind study to receive two doses of either albendazole or placebo prio...
