Giardia lamblia is the causative agent of giardiasis, one of the most common parasitic infections of the human intestinal tract. This disease most frequently affects children causing abdominal pain, nausea, vomiting, acute or chronic diarrhea, and malabsorption syndrome. In undernourished children, giardiasis is a determining factor in retarded physical and mental development. Antigiardial chem...

OBJECTIVE To study epidemiology and possible risk factors associated with the development of cryptosporidiosis among European patients with AIDS. METHODS An inception cohort of 6548 patients with AIDS, consecutively diagnosed from 1979 to 1989, from 52 centres in 17 European countries was studied. Data on all AIDS defining events were collected retrospectively from patients' clinical records....

Cryptosporidiosis causes gastroenteritis and is transmitted to humans via contaminated water and food, and contact with infected animals and people. We analyse long-term cryptosporidiosis patterns across Australia (2001-2012) and review published Australian studies and jurisdictional health bulletins to identify high risk populations and potential risk factors for disease. Using national data o...

Cryptosporidiosis, caused by Cryptosporidium parvum, is self-limited in immunocompetent hosts but may cause chronic diarrhea in patients with acquired immunodeficiency syndrome (AIDS). Substance P (SP), a neuropeptide belonging to the tachykinin family, is expressed in gastrointestinal tract and can cause electrogenic chloride anion secretion. Therefore, we studied SP mRNA and protein expressio...

background: giardia lamblia is a common intestinal parasite associated with social or personal problems. giardiasis is distributed all over the world; however, the infection is more prevalent in developing countries. metronidazole is now considered as a drug of choice for giardiasis treatment. the increasing number of reports of refractory cases as well as side effects of this drug resulted in ...

Diffuse nodular lymphoid hyperplasia of the gastrointestinal tract is a rare disease characterized by numerous small polypoid nodules in the small intestine, large intestine, or both. It is associated with immunodeficiency and infection, such as Giardia lamblia and Helicobacter pylori. Although diffuse nodular lymphoid hyperplasia associated with common variable immunodeficiency (CVID) and giar...

In this study parasitic infection of bobwhite and Japanese quails were clarified in farms of Garmsar city in province of Semnan. Forty quails from two breeds randomly were selected and they examined to identify all internal and external parasites .Finding was shown that five percent of the quails examined harbored one or more species of helminthes. Two cestodes, Raillietina echinobothrida and R...

BACKGROUND: Giardia lamblia is the most frequently identified human intestinal parasite in Canada with prevalence estimates of 4-10%. However, infection rates vary by geographical area and localized 'pockets' of high or low infection rates are thought to exist. Water-borne transmission is one of the major routes of infection. Sources of contamination of drinking water include humans, domestic a...

OBJECTIVES To determine the prevalence of cryptosporidiosis and the associated factors, and characterise the Cryptosporidium isolates from children aged five years and less with diarrhoea. DESIGN A prospective cross-sectional study. SETTING This was a health facility and laboratory based study. Screening for Cryptosporidium oocysts was done at the Microbiology laboratory, School of Medicine...

We compared the epidemiologic characteristics of cyclosporiasis and cryptosporidiosis in data from a cohort study of diarrhea in a periurban community near Lima, Peru. Children had an average of 0.20 episodes of cyclosporiasis/year and 0.22 episodes of cryptosporidiosis/year of follow-up. The incidence of cryptosporidiosis peaked at 0.42 for 1-year-old children and declined to 0.06 episodes/chi...
