conclusions health disobedience and neglect of local residents were the causes of water pollution that was controlled with preventional measures, with performing daily chlorination of brick kilns drinking water and diarrheal disease treatment of the patients. results a total of 120 workers were studied (60 cases and 60 controls) who were the same from age and sex point of view. clinical signs o...

BACKGROUND In Bangladesh, increases in cholera epidemics are being documented with a greater incidence and severity. The aim of this prospective study was to identify the prevalence and importance of V. cholerae O1 and enterotoxigenic Escherichia coli (ETEC) as causal agents of severe diarrhea in a high diarrhea prone urban area in Dhaka city. METHODOLOGY Systematic surveillance was carried o...

To know prevalence of rotavirus diarrhea subgroups and serotypes, a prospective study was conducted in rural, periurban and urban communities at Chandigarh. Weekly surveillance for diarrheal episodes was carried out in 110 families each from rural, periurban and urban localities constituting 584 children < 5 years of age from October, 1988 to February, 1991. Stool samples of 218 diarrheal episo...

BACKGROUND Studies examining the etiology-specific effects of diarrheal disease on growth are limited and variable in their analytic methods, making comparisons difficult and priority setting based on these findings challenging. A study by Black et al (Black RE, Brown KH, Becker S. Effects of diarrhea associated with specific enteropathogens on the growth of children in rural Bangladesh. Pediat...

1. The disease was almost certainly infectious. 2. Its eradication offered much greater practical difficulties than are presented by certain other infections of mice. 3. A definite tendency toward greater susceptibility in first litters as contrasted with subsequent ones was noted. 4. Advantage could be taken of this increasing resistance to keep the infected colony in efficient production, but...

Congenital diarrheal disorders (CDDs) are a group of inherited enteropathies with a typical onset early in the life. Infants with these disorders have frequently chronic diarrhea of sufficient severity to require parenteral nutrition. For most CDDs the disease-gene is known and molecular analysis may contribute to an unequivocal diagnosis. We review CDDs on the basis of the genetic defect, focu...

Since the time of John Snow we have known that contaminated water can lead to outbreaks of waterborne disease. This association is commonly acknowledged by both the scientific community and the lay public. But among those who study water quality and diarrheal diseases, the association is muddied by many nuanced questions. For example, what is the relative contribution to the burden of diarrheal...

Campylobacter jejuni, a gram-negative spiral shaped bacterium, is a frequent cause of gastrointestinal food-borne illness in humans throughout the world. Illness with C. jejuni ranges from mild to severe diarrheal disease. This article focuses on Campylobacter virulence determinants and their potential role in the development of C. jejuni-mediated enteritis. A model is presented that diagrams t...

Twenty-eight United States adult travelers to developing countries participated in a prospective study designed to determine whether there was an association between diarrheal illness and, the acquisition of strains of enteropathogenic Escherichia coli. Stool specimens were collected and stored in transport media before, during, and after travel and at the onset of any diarrheal illness. From e...
