Drug resistance in Giardia duodenalis
Biotechnology Advances, 2015Giardia duodenalis is a microaerophilic parasite of the human gastrointestinal tract and a major contributor to diarrheal and post-infectious chronic gastrointestinal disease world-wide. Treatment of G. duodenalis infection currently relies on a small number of drug classes.

Free radical detoxification in Giardia duodenalis
Molecular and Biochemical Parasitology, 1995Non-denaturing polyacrylamide gels were used to analyse superoxide dismutase (SOD), catalase, peroxidase, NADH oxidase and NADH peroxidase in the microaerophilic protozoan parasite Giardia duodenalis. A cytosolic H2O-producing NADH oxidase and membrane-associated NADH peroxidase were readily detected from G. duodenalis.

Molecular characterization of Giardia duodenalis in Yemen
Experimental Parasitology, 2013Giardia duodenalis is an important intestinal protozoan in Yemen with infection rates ranging from 18% to 27%. To date, there has been no genotyping study to provide a better understanding of the transmission dynamic. This study was conducted to genotype and subtype G. duodenalis in Yemen.

Giardia duodenalis infection and wastewater irrigation in Pakistan
Transactions of the Royal Society of Tropical Medicine and Hygiene, 2006 The risk of Giardia duodenalis (Giardia) infection in farmers using untreated wastewater in agriculture was investigated in the city of Faisalabad, Pakistan, through a cross-sectional study. The study found a significantly increased risk of (asymptomatic) Giardia infection in wastewater farming households when compared with farming households using ...

Quantitative proteomics in Giardia duodenalis —Achievements and challenges
Molecular and Biochemical Parasitology, 2016Giardia duodenalis (syn. G. lamblia and G. intestinalis) is a protozoan parasite of vertebrates and a major contributor to the global burden of diarrheal diseases and gastroenteritis. The publication of multiple genome sequences in the G. duodenalis species complex has provided important insights into parasite biology, and made post-genomic ...

Virulent Avian Giardia duodenalis Pathogenic for Mice
Parasitology Today, 1998Early in 1995, a sulphur-crested cockatoo captured in the wild died along with several other cage mates, apparently of an overwhelming, acute infection of Giardia. Trophozoites isolated from the dead bird and established in traditional Giardia axenic medium were infective to mice and established chronic infections associated with weight gain impairment.

In vitro effects of propolis on Giardia duodenalis trophozoites
Phytomedicine, 2006In order to improve the current chemotherapy of Giardia infection, potential antigiardial agents have been screened, including natural products. Propolis, a resinous hive product collected by bees, has attracted attention as a useful and popular substance with several therapeutic activities.

Giardia duodenalis in humans and animals – Transmission and disease
Research in Veterinary Science, 2021Giardia duodenalis is a protozoan parasite infecting the upper intestinal tract of humans, as well as domestic and wild animals worldwide. Transmission of giardiasis occurs through the faecal-oral route, and may be either direct (i.e., person-to-person, animal-to-animal or zoonotic) or indirect (i.e., waterborne or foodborne).

Effect of vinegar on the viability of Giardia duodenalis cysts
International Journal of Food Microbiology, 2009The inactivation of Giardia duodenalis cysts by vinegar was investigated. Experiments were carried out in 100 ml volume of vinegar (acetic acid 4%), undiluted or diluted in distilled water in ratios of 1:1, 1:15.6, and 1:62.5 (vol/vol), which were inoculated with 5x10(5) cysts obtained from human feces.

Giardia duodenalis assemblages in Egyptian children with diarrhea
European Journal of Clinical Microbiology & Infectious Diseases, 2015Giardia duodenalis is considered the most common cause of parasitic diarrhea worldwide. Genetic studies revealed that at least eight assemblages (A-H) exist. Of these assemblages, A and B are found primarily in human beings and occasionally in animals. The association between clinical symptoms and G. duodenalis assemblages is controversial.
