In Southeast Asia, a total of 59 species of foodborne intestinal flukes have been known to occur in humans. The largest group is the family Heterophyidae, which constitutes 22 species belonging to 9 genera (Centrocestus, Haplorchis, Heterophyes, Heterophyopsis, Metagonimus, Procerovum, Pygidiopsis, Stellantchasmus, and Stictodora).

Intestinal parasitic infections are one of the major causes of diarrhea in human immunodeficiency virus (HIV) seropositive individuals. Antiretroviral therapy has markedly reduced the incidence of many opportunistic infections, but parasite-related diarrhea still remains frequent and often underestimated especially in developing countries. The present hospital-based study was conducted to deter...

conclusions the frequency of b. hominis in the study was more than other reports from iran. this study revealed that among hospitalized children with diarrhea, b. hominis was the most common protozoon. results out of 160 stool samples were examined, in 37 cases (23%) including 25 boys and 12 girls, b. hominis was the most frequent protozoa, followed by giardia lamblia in 19 cases (12%). e. hist...

background: giardia lamblia is one of the most prevalent intestinal flagellate protozoa that infects a wide range of vertebrate hosts causing severe intestinal disorder in children.this study was performed to determine subspecies of g.lamblia by the pcrrflp method, targeting the glutamate dehydrogenase (gdh) locus, in hospitalized children at urmia mutahhari hospital, west azerbaijan province,i...

Gastrointestinal symptoms, such as abdominal pain and diarrhea, are frequently observed in patients with Plasmodium falciparum malaria. However, the correlation between malaria intestinal pathology and intestinal microbiota has not been investigated. In the present study, infection of C57BL/6 mice with P. berghei ANKA (PbA) caused intestinal pathological changes, such as detachment of epithelia...

Background and Objective: Blastocystis sp. is an anaerobic, single-celled intestinal parasite with global prevalence that is found in the lower digestive tract of humans and many animals, such as numerous types of vertebrates. To date, 17 genotypes have been identified. Nine of these genotypes are common in humans. Organism is found in both healthy and compromised individuals, hence its pathoge...

giardia, a protozoan parasite, resides in the small intestine in man. this parasite damages the mucosal intestinal surface and in severe cases produces malabsorption and it may also affect mineral absorption, especially zinc. in this study a total of 118 infested and 43 non-infested persons as a control group were selected. from each patient a 5 ml blood sample was obtained. the serum was separ...
