Molecular epidemiology of Blastocystis sp. isolates in Bandar Abbas, South of Iran

Background and Objective: Blastocystis sp. is an anaerobic, single-celled intestinal parasite with global prevalence that is found in the lower digestive tract of humans and many animals, such as numerous types of vertebrates. To date, 17 genotypes have been identified. Nine of these genotypes are common in humans. Organism is found in both healthy and compromised individuals, hence its pathoge...

Epidemiology and pathogenicity of Blastocystis hominis.

A prospective study was performed on a large outpatient population to evaluate the epidemiology and pathogenicity of Blastocystis hominis. Patients with stool specimens positive for B. hominis and negative for other bacterial and parasitic pathogens were sent a questionnaire and were requested to submit a follow-up specimen for ova-and-parasite examination. B. hominis was identified in 530 of 1...

Molecular Epidemiology of Giardia, Blastocystis and Cryptosporidium among Indigenous Children from the Colombian Amazon Basin

The incidence and prevalence of intestinal parasites in children is most likely due to lack of natural or acquired resistance and differences in behavior and habits closely related to environmental and socioeconomic determinants. The most important protozoa that parasitize humans are Giardia, Entamoeba, Blastocystis, and Cryptosporidium. These parasites present wide intraspecific genetic divers...

Molecular Epidemiology of Human Papillomavirus in Pterygium

Abstract Background and Objective: Ophthalmic pterygium is a potentially vision-threatening lesion of unknown etiology that often extends on the corneal surface and has a worldwide distribution. Despite various studies, the pathogenesis of pterygium remains unclear and the involvement of human papillomavirus is controversial. We aimed to investigate the involvement of papillomavirus in pte...
