Comparison of stool examination techniques to detect Opisthorchis viverrini in low intensity infection.

Opisthorchiasis, caused by Opisthorchis viverrini, remains the public health significance in Thailand, particularly in the northeastern region. Number of parasitological techniques is available for diagnosis. However, the detection the parasite's eggs in stool still referred as gold standard.

Genotypic characterization of Enterocytozoon bieneusi in specimens from pigs and humans in a pig farm community in Central Thailand.

We determined that 15.7% of pigs and 1.4% of humans in a pig farm community in central Thailand harbored Enterocytozoon bieneusi.

Identification of genotypes of Enterocytozoon bieneusi from stool samples from human immunodeficiency virus-infected patients in Thailand.

We identified genotypes of Enterocytozoon bieneusi from 33 stool samples of Thai human immunodeficiency virus (HIV)-infected adult patients. Genotype D was identified at the highest frequency (36.4%), while genotype E was the second most common (15.

Transmission of Enterocytozoon bieneusi genotype a in a Thai orphanage.

A cross-sectional study of Enterocytozoon bieneusi infection in children who lived in an orphanage in Bangkok, Thailand was conducted in April 2003. Two hundred ninety stool specimens were collected and examined under light microscopy after staining with gram-chromotrope. Confirmation of E.

Spore shedding pattern of Enterocytozoon bieneusi in asymptomatic children.

Stool samples from seven human immunodeficiency virus (HIV)-negative and two HIV-positive children with asymptomatic Enterocytozoon bieneusi infections were daily examined to quantify spore shedding using Gram-chromotrope staining under light microscopy. The spore shedding pattern and intensity in these children was variable. Mean spore concentrations in the stool samples from these children ranged from 2.

Evaluation of DNA extraction and PCR methods for detection of Enterocytozoon bienuesi in stool specimens.

An evaluation of the sensitivities of three DNA extraction methods, i.e., FTA filter paper, a QIAamp stool mini kit, and a conventional phenol-chloroform method, by using specimens with known concentrations of Enterocytozoon bieneusi spores was performed.
