Stool examination by sedimentation method in 82 homeless individuals living in the streets of Rio de Janeiro City, revealed Ascaris lumbricoides eggs in 40 (48.85%), Trichuris trichiura in 27 (32.9%) and hookworm in 7 (8.5%).

A digital rectal examination is a highly important procedure carried out on infants and children during visits to the gastroenterology clinic, but is often accompanied with physiologic and psychologic trauma in patients, along with being diagnostically inaccurate in the results obtained from it. In order to avoid causing discomfort to the patients, and to improve the accuracy of the results obt...

Soil transmitted helminths are parasitic groups of worms that live in countries with subtropical or tropical climates. In humans, when exposed to eggs larvae, they can cause infection. Stool examination is divided into qualitative and quantitative examination. Qualitative direct examination, flotation, tape, deposition, thick preparations. Kato-Katz Stoll quantitative. The purpose this study wa...

background : strongyloides stercoralis is a prevalent parasite in some rural areas in the north of iran. we decided to investigate whether the 18s ribosomal dna sequence of the parasite in iran is similar to the findings of the other re­searchers. methods :  we collected 3514 stool samples from gilan and mazandaran, northern iran, during the year 2005-2006, from which 96 were found infected wit...

This study was performed on 1350 school children from 9 different villages in Sharkia Governorate to investigate the real situation of endemicity of fascioliasis in the area. Stool examination using modified Kato thick smear method was performed to detect Fasciola infection and other parasites. Those with negative stool samples were examined serologically by ELISA test to detect anti-Fasciola I...

BACKGROUND Strongyloidiasis is mostly an asymptomatic infection and diagnosis of latent infections is difficult due to limitations of current parasitological and serological methods. This study was conducted to set up a PCR-based method for molecular diagnosis of Strongyloides stercoralis infection by detection of copro-DNA in stool samples. METHODS A total of 782 fresh stool samples were col...

Background: Giardia lamblia is the most frequent human intestinal protozoan worldwide. Diagnosis of G. lamblia by microscopic examination of stool is common, but ELISA & IFA methods have been used in research and epidemiological studies recently. To produce polyclonal antibodies for designing ELISA & IFA kites molecular and genomic studies (PCR and parasitic culture) as well as other epidemiolo...
