The majority of Giardia infections are transmitted by the fecal-oral route and cause giardiasis. Children who live in crowded conditions or low socio-economic areas are the risk group for Giardia infection. Interestingly, most of them are asymptomatic or only mildly infected and can shed the Giardia cysts in the environment. Thus, the diagnosis of Giardia infection in asymptomatic or mild infec...

Giardia duodenalis is globally recognized as an important zoonotic intestinal protozoan parasite. So far, eight assemblages of G. duodenalis (A-H) have been identified. Substantial evidence suggests the zoonotic potential of assemblages A, B, and E in livestock. In this study, the genotype of Giardia duodenalis isolates was genetically identified by determining the sequence of ssu-rRNA gene and...

BACKGROUND Giardia duodenalis is a ubiquitous protozoan parasite that has emerged as a significant opportunistic human pathogen. G. duodenalis may have a deleterious effect on animal growth and performance, therefore its potential as a production limiting organism should not be discounted. We therefore undertook this study to determine management and environmental factors in feedlots that influ...

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...

Giardia duodenalis is a flagellated intestinal protozoan responsible for infections in various hosts including humans and several wild and domestic animals. Few studies have correlated environmental contamination and clinical infections in the same region. The aim of this study was to compare groups of Giardia duodenalis from clinical and environmental sources through population genetic analyse...

BACKGROUND Giardiasis is caused by the intestinal protozoan parasite Giardia duodenalis (synonyms: G. lamblia, G. intestinalis), which is one of the most frequent parasites that infect Turkish children. However, molecular characterization of G. duodenalis in Turkey is relatively scarce. The present work aimed at genotyping G. duodenalis isolates from Turkey using molecular techniques. MATERIA...

Background and purpose: Giardia cyst and trophozoite have invariant morphologies, therefore, investigating aspects such as host specificity, transmission patterns and clinical behavior of the parasite in hosts requires molecular characterization of the parasites isolated from clinical samples. The aim of this study was to characterize giardiasis isolated from human fecal samples with symptomati...

Despite many reports on the shedding of Giardia parasites by scouring calves, the role of Giardia as a cause of calf diarrhea is still controversial. To elucidate the role of Giardia duodenalis in calf scours, diagnostic samples from 189 scouring calves were tested by different assays during a 1-year-study period. Giardia antigens were detected in 22/189 scouring calves by a fecal-based enzyme-...

Background Although the prevalences of infection with the protozoan parasites Cryptosporidium spp. and Giardia duodenalis in humans appear to be relatively high in the Canadian North, their transmission patterns are poorly understood. Objective To determine the detection rate and the molecular characteristics of Cryptosporidium spp. and Giardia duodenalis in diarrhoeic patients in the Qikiqtani...
