Investigating of Human Giardia intestinalis Assemblage in Markazi province, IRAN

Abstract

: Introduction: Giardiasis is a worldwide infection of the small intestine. The causative agent of this disease is a flagellate protozoan called Giardia . It is only transmitted by mature cysts. It is important to identify the geographical distribution of Giardia intestinalis assemblages and genotypes in order to determine their transmission pattern in each region of the country. Therefore, the present study was performed to determine the predominant Giardia assemblage in human samples in Arak. These isolates were recorded in GenBank (MT584765- MT584776). Results of current study showed assemblage A of Giardia intestinalis is the dominant in Arak. Conclusion: The assemblage of all isolates that obtained from current study was matched with genotype A. Given that assemblage A is mostly contaminating humans and other mammals, it seems the transmission of Giardia is zoonotic in Arak city.
