background: this study was conducted to determine of molecular epidemiology of the giardia lamblia by pcr-rflp method in tehran, capital of iran. methods: thirty eight stool samples were randomly selected from 125 patients diagnosed with giardiasis using microscopy in tehran. dna extraction of some samples were performed by phenol/chloroform/isoamyl alcohol method and to raise the sen­sitivity ...

BACKGROUND Members of the Polish Military Contingent (PMC) have been stationed in Afghanistan since 2002. They typically serve in areas characterised by low standards of sanitation which often leads to the development of food- and waterborne diseases. The aim of the study was to evaluate the prevalence of Giardia intestinalis infections among Polish soldiers deployed to Afghanistan. The researc...

BACKGROUND Both giardiasis and zinc deficiency are serious health problems worldwide. In Mexico, the prevalence of G. intestinalis was estimated at 32% in 1994. It remains a health problem in northwestern Mexico. Recent surveys (1987, 1995, and 1999) reported zinc deficiency in the Mexican population. The association of giardiasis and malabsorption of micronutrients has been well documented, al...

There are no meta-analyses specifically describing the prevalence of zoonotic and non-zoonotic genotypes of Giardia intestinalis in cats, which would be useful in defining the importance of cats as a source of zoonotic transmission. We performed a systematic review of the literature in three databases (PubMed, Scopus and SciELO) to assess the proportion of cats that were infected with specific ...

Giardia Giardia is a flagellate protozoan parasite commonly encountered in small animal veterinary practice. The most common clinical syndrome associated with Giardia is acute small bowel diarrhea, but in some cases acute large bowel diarrhea, chronic small or large bowel diarrhea, or rarely acute or chronic vomiting may occur. Studies throughout the world have found infection rates ranging fro...

This study determined the distribution and zoonotic potential of Giardia duodenalis assemblage types among canine and feline fecal samples from Ontario. The effectiveness of Giardia assemblage typing methods by sequencing the genes of small subunit ribosomal RNA (ssu-rRNA), β-giardin (bg), glutamate dehydrogenase (gdh), and triose phosphate isomerase (tpi) was evaluated simultaneously. From 200...

Five genera of potentially zoonotic bacteria and parasites were detected in environmentally collected fecal samples from a remote indigenous community in Northern Saskatchewan, Canada. Organisms identified include Toxocara canis, Echniococcus granulosus, Giardia duodenalis, Cryptosporidium spp., and Campylobacter spp. The prevalence and intensity of Giardia spp. and Campylobacter spp. in fecal ...

Seven species of rotifers representing 6 genera, Epiphanes, Plationus, Asplanchna, Philodina species A, Philodina species B. Platyias, and Brachionus, were exposed to Giardia cysts isolated from the feces of experimentally infected holstein calves. Giardia cysts were prestained with a fluorescein isothiocyanate-conjugated monoclonal antibody and mixed with viable rotifers on 3-well Teflon-coate...

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...
