Rapid tagging and integration of genes in Giardia intestinalis.

Molecular Identification of Giardia intestinalis and Blastocystis hominis Genotypes from Fecal Samples in Khuzestan Province, Iran

Background and purpose: Giardia and Blastocystis are common parasites of humans with a wide range of hosts. The aim of this study was to identify the genotypes of Giardia intestinalis and Blastocystis hominis in individuals attending Bavi health centers in Khuzestan province, Iran. Materials and methods: In this study, 30 positive stool samples of Giardia and Blastocystis were collected from i...

Zoonotic genotype of Giardia intestinalis detected in a ferret.

Giardia intestinalis has been found in a variety of mammals, including humans, and consists of host-specific and zoonotic genotypes. There has been only 1 study of G. intestinalis infection in weasels, but the genotype of its isolate remains unclear. In this study, we report the isolation of Giardia in a ferret exhibited at a pet shop. The isolate was analyzed genetically to validate the possib...

Prevalence of Giardiasis in Children Attending Semi-urban Daycare Centres in Guatemala and Comparison of 3 Giardia Detection Tests

Giardia intestinalis is an intestinal parasite widely prevalent in children attending daycare centres worldwide and has been associated with undernutrition. Stool samples from 48 Guatemalan children (aged 1.5-7 years) attending participating daycare centres were analyzed over five weeks for presence of Giardia intestinalis using light microscopy, ELISA, and rapid dipstick test. Giardia prevalen...

A critical assessment of two real-time polymerase chain reaction assays targeting the (SSU) rRNA and gdh genes for the molecular identification of Giardia intestinalis in a clinical laboratory

Transcription of meiotic-like-pathway genes in Giardia intestinalis.

The reproductive mechanism of Giardia intestinalis, considered one of the earliest divergent eukaryotes, has not been fully defined yet. Some evidence supports the hypothesis that Giardia is an exclusively asexual organism with a clonal population structure. However, the high genetic variability, the variation in ploidy during its life cycle, the low heterozygosity and the existence of genes in...
