Two core microRNA (miRNA) pathway proteins, Dicer and Argonaute, are found in Giardia lamblia, a deeply branching parasitic protozoan. There are, however, no apparent homologues of Drosha or Exportin5 in the genome. Here, we report a 26 nucleotide (nt) RNA derived from a 106 nt Box C/D snoRNA, GlsR2. This small RNA, designated miR5, localizes to the 3' end of GlsR2 and has a 75 nt hairpin precu...
Background: Giardia is one of the infectious agents that can be transmitted by surface water and cause a disease. We designed and fabricated a magnetic system to separate the giardia cysts from water. Materials and Methods: In this study, giardia cysts were concentrated by sucrose floatation method. The cysts were mixed with physiological saline and their concentration was adjusted to 100,000 c...
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...
Background: Paediatric diarrhoea, the burning issue of nowadays, drastically affects child mortality and morbidity. Apart from virus bacteria, parasites also play an important role in causing diarrhoea at that age group. Giardiasis, most prevalent among parasitic infections, though neglected yet carries significance because its long term health issues. The aim study was to identify intestinal b...
In order to investigate the genotypes of Giardia duodenalis from domestic and farm animals in Italy, 21 Giardia isolates, 17 from dogs, 1 from cat and 3 from dairy calves, were genetically characterised by SSU-rRNA gene sequencing. Among dogs, 76.5% of isolates showed the dog-specific genotypes (Assemblages C, D and C/D mixed Assemblage) and 23.5% exhibit potential zoonotic genotypes (Assemblag...
