Multilocus sequence typing of genotypes circulating in humans in a major metropolitan area.

is an intestinal protozoan parasite of humans and animal hosts and comprises eight microscopically indistinguishable molecularly-diverse lineages designated as assemblages A-H. Assemblages A and B are the primary sources of infections in humans and a wide range of mammals. Here, we identified assemblages, and inter-/intra-assemblage genetic diversity of human isolates based on the multilocus sequence typing of the triosephosphate isomerase (), β -giardin (), and glutamate dehydrogenase () loci.

Prevalence and Risk Factors of Human Intestinal Parasites in Roudehen, Tehran Province, Iran.

Background: Intestinal parasitic infections are among the most common infections and health problems worldwide. Due to the lack of epidemiologic information of such infections, the prevalence of, and the risk factors for, enteric parasites were investigated in residents of Roudehen, Tehran Province, Iran.

Methods: In this cross-sectional study, 561 triple fecal samples were collected through a two-stage cluster-sampling protocol from Jun to Dec 2014.
