Unlike acute diarrhea, the role of pathogens in persistent diarrhea in children in Nepal is unclear. Protozoal parasites are suspected to be a major cause. The study was carried out to find the association between protozoal agents and persistent diarrhea in children below age 5 years from western Nepal. Stool samples were collected from 253 children with persistent diarrhea, from 155 children w...

Cryptosporidiosis, microsporidiosis, and cyclosporiasis were studied in four groups of Tanzanian inpatients: adults with AIDS-associated diarrhea, children with chronic diarrhea (of whom 23 of 59 were positive [+] for human immunodeficiency virus [HIV]), children with acute diarrhea (of whom 15 of 55 were HIV+), and HIV control children without diarrhea. Cryptosporidium was identified in specim...

adenoviruses (advs) types 40 and 41 are the causative agents of diarrhea in children. hence, rapid sensitive and specific detection of these viruses are of clinical importance. the customary methods such as propagation of virus in cell culture suffer from limitations. detection of immobilized amplified products in a one phase system (diapops) method has the potential to overcome these problems....

In a prospective study carried out in two urban centers in northeastern Brazil, 195 HEp-2-adherent Escherichia coli strains were isolated; 110 were identified as the only pathogen in stools of children with diarrhea, and 85 were from controls. Enteropathogenic E. coli isolates were identified in 21 children with diarrhea (8.9%) and 7 children without diarrhea (3.0%), and they were significantly...

introduction: diarrheal diseases are a serious health problem and important causes of growth retardation and death in the developing world, especially those of prolonged duration. since diarrhea is constantly found in children with zinc deficiency, very studies supported zinc supplements beneficial on the duration and severity of diarrhea among children. we review the impact of zinc effects on ...

conclusions this study suggests that epec strains are important contributors to diarrhea in iranian children. because of the weakness of routine microbiological tests and poor specifity of serological tests, it is recommended that the epec strains are better detected by molecular methods. results the e. coli isolates were confirmed by the presence of the uida gene. the epec was diagnosed in 6 c...
