AIMS To assess the prevalence of gastric giardiasis in patients undergoing upper gastrointestinal endoscopy, and to define the clinicopathological correlates of gastric Giardia lamblia infection. METHODS Consecutive gastric biopsy specimens (n = 15,023) from 11,085 patients, taken at Feltre City Hospital (north eastern Italy) from January 1986 to December 1991, were histologically and immunoc...

Previous evidence has suggested an association between consumption of unfiltered water from Loch Lomond, Scotland, and cryptosporidiosis. Before November 1999, this water had been only microstrained and disinfected with chlorine; however, since that time, physical treatment of the water (coagulation, rapid gravity filtration) has been added. To determine risk factors, including drinking water, ...

The test for exocrine pancreatic function using N-benzoyl-L-tyrosyl-p-aminobenzoic acid (BTPABA test) was assessed in 7 patients with giardiasis and 7 healthy controls. Cumulative percent p-aminobenzoic acid (PABA) recovery in 6 hr was significantly lower in patients with giardiasis, compared with the control group. When an equivalent dose of free PABA was given, there were no differences in PA...

OBJECTIVE To describe a nosocomial outbreak of cryptosporidiosis during four months after June 1989. SETTING A department of infectious diseases in Copenhagen, seeing about half the patients with AIDS in Denmark. SUBJECTS 73 HIV antibody negative subjects and 60 antibody positive subjects admitted as inpatients during the transmission period of the outbreak (20 June-14 August), of whom 18 (...

This study investigated the levels of iron, zinc, and copper and their demolishing effects against lipid peroxidation in chronic giardiasis. Serum iron, zinc and copper levels, erythrocyte cytosolic superoxide dismutase activity, and malondialdehyde levels were measured in 34 children with chronic giardiasis and were compared with controls. The serum iron and zinc levels and erythrocyte superox...

In this research 783 child of Day care centers (D. C. C) of Qazvin Alvand, Industrial Cities had stoll examination for Giardiasis. Results were: Giardiasis was found in 13.5  % of children with peak incidence in 4-5, 6-7 years, more in female than male, incidence of Giardiasis were increased with decrease of Educational Level of mothers and increase of family members. Giardiasis was more in D....

Humans are hosts to nearly 300 species of parasitic worms and over 70 species of protozoa, some derived from our primate ancestors and some acquired from the animals we have domesticated or come in contact with during our relatively short history on Earth. Our knowledge of parasitic infections extends into antiquity, and descriptions of parasites and parasitic infections are found in the earlie...

Major waterborne cryptosporidiosis and giardiasis outbreaks associated with contaminated drinking water have been linked to evidence of suboptimal treatment. Cryptosporidium parvum oocysts are particularly more resistant than Giardia lamblia cysts to removal and inactivation by conventional water treatment (coagulation, sedimentation, filtration and chlorine disinfection); therefore, extensive ...

Giardiasis, which is caused by Giardia lamblia infection, a relevant cause of morbidity and mortality worldwide. Because no vaccines are currently available to treat giardiasis, chemotherapeutic drugs the main options for controlling infection. Evidence has shown that nitro drug nitazoxanide (NTZ) commonly prescribed treatment giardiasis; however, mechanisms underlying NTZ’s antigiardial activi...
