In this paired case-control study of infants with diarrhea in São Paulo, we examined the association between HEp-2-adherent Escherichia coli strains and diarrhea. We tested isolates from stool specimens of infants with diarrhea and matched controls in an HEp-2 cell adherence assay; we then hybridized isolates with DNA probes and identified enteropathogenic E. coli (EPEC), enteroaggregative E. c...

This study examined the role of enteric pathogens and infant, family, and household characteristics in persistent diarrhea. Bedouin infants from southern Israel were followed from birth to age 18-23 months. During monthly home visits, stool samples were obtained, and feeding practices and history of diarrhea were determined, and at age 3 months, an environmental assessment was done. Diarrhea su...

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...

BACKGROUND Acute diarrhea is the second leading cause of mortality among children under 5 years of age in developing countries. The pathogen most strongly associated with diarrhea is rotavirus followed by enteric pathogens such as bacteria, helminthes and protozoan. Adequate sanitation and water supply contribute to decrease acute diarrhea incidence of most etiologic agents, although vaccinatio...

Background & Aims: Clostridium difficile has been identified as a pathogen in antibiotic associated diarrhea (AAD), pseudomembranous colitis and also nosocomial diarrhea. The present study was performed to find the prevalence of toxigenic strains of C .difficile isolated from diarrhea patients hospitalized in Tehran hospitals. Method: A total of 98 fecal samples obtained during July to December...

Diarrhea is a common comorbidity present in patients with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) who are treated with highly active antiretroviral therapy. With a multifactorial etiology, this diarrhea often becomes difficult to manage. In addition, some antiretrovirals are associated with chronic diarrhea, which potentially creates an adherence barrier to a...

Enteroaggregative Escherichia coli (EAEC) is frequently found in diarrheal stools worldwide. It has been associated with persistent diarrhea, weight loss, and failure to thrive in children living in developing countries. A number of important EAEC virulence genes are identified; however, their roles in acute and persistent diarrhea have not been previously investigated. The aim of this study wa...

We performed a systematic literature review and meta-analysis examining the association between diarrhea in young children in nonindustrialized settings and Giardia lamblia infection. Eligible were case/control and longitudinal studies that defined the outcome as acute or persistent (>14 days) diarrhea, adjusted for confounders and lasting for at least 1 year. Data on G. lamblia detection (main...

background and objectives: incidence of hospital-acquired diarrhea has increased rapidly and burn patients are at high risk of getting it. infection with c. difficile is the most common cause of antibiotic associated diarrhea. the aim of this study was to determine the baseline characteristics and clinical presentation of hospital-acquired diarrhea and compare c. difficile and non- c. difficile...

aim :  the aim of this study was to investigate the in vitro inhibitory effect of probiotic e.coli nissle 1917 (ecn) strain against pathogenic bacteria isolated from patients with diarrhea. background : probiotics are viable microorganisms that are shown to have beneficial effects on human health. ecn is a typical example of probiotics; however, there are few reports of it being administered fo...
