We examined demographic, microbiologic, and clinical data from patients presenting during 1988, 1998, and 2004 flood-associated diarrheal epidemics at a diarrhea treatment hospital in Dhaka, Bangladesh. Compared with non-flood periods, individuals presenting during flood-associated epidemics were older, more severely dehydrated, and of lower socioeconomic status. During flood-associated epidemi...
OBJECTIVE To provide recent guidelines to reduce the incidence of diarrheal diseases. We discuss the definition, clinical aspects, pathophysiology, diagnosis, management, and prevention of persistent diarrhea. SOURCES Electronic search of the MEDLINE database, Google search. SUMMARY OF THE FINDINGS Acute diarrhea may be caused by a variety of agents, including bacterial, viral, and protozoa...
Pathogens in the gastrointestinal tract exist within a vast population of microbes. We examined associations between pathogens and composition of gut microbiota as they relate to Shigella spp./enteroinvasive Escherichia coli infection. We analyzed 3,035 stool specimens (1,735 nondiarrheal and 1,300 moderate-to-severe diarrheal) from the Global Enteric Multicenter Study for 9 enteropathogens. Di...
Rotavirus is one of the most common causes of childhood diarrheal disease and deaths in sub-Saharan Africa. This article reviews community- and hospital-based surveillance of rotavirus disease in Bissau, Guinea-Bissau, West Africa. Here, rotavirus infections exhibit a seasonal pattern, with annual epidemics occurring during the relatively dry and cooler months, from January to April, and few ca...
Bacillus cereus strains were tested for production of diarrheal enterotoxin by the reverse passive latex agglutination test and for presence of B. cereus enterotoxin gene (bceT) by polymerase chain reaction. About 50% of 56 B. cereus strains reacted positive in broth culture in the reverse passive latex agglutination test, while the bceT gene was detected in 41.1%. Sixteen percent of the strain...
Diarrheal disease is a leading cause of child mortality in low-income settings and morbidity across a range of settings. A growing number of studies have addressed the economic value of new and emerging vaccines to reduce this threat. We conducted a systematic review to assess the economic value of diarrheal vaccines targeting a range of pathogens in different settings. The majority of studies ...
Acute diarrheal illness is a global health problem that may be exacerbated by concurrent infection. Using Citrobacter rodentium, a murine model of attaching and effacing diarrheagenic Escherichia coli, we demonstrate that persistent Helicobacter hepaticus infection modulates host responses to diarrheal disease, resulting in delayed recovery from weight loss and from tissue damage. Chronic colit...
An epidemiological cross sectional study was undertaken in Yaoundé in 2002 and updated in 2005. Focused on health within the city, the objectives were to measure diarrheal prevalence and to identify the risk factors associated with them. Results of microbiological examinations have revealed an urban average prevalence rate of 14.5%. Access to basic services in the living environment appears to ...
The anti-diarrheal activity of the alcohol and aqueous extracts of the roots of Dodonaea viscosa (Sapindaceae) was investigated by castor oil induced diarrhea in mice. The parameters of this study were number of diarrheal episodes and mean weight of stool of mice. The percentage protection in extract treated animals showing diarrhea was compared with castor oil treated and loperamide treated an...
INTRODUCTION Norovirus is not usually investigated in diarrheal patients in Bangladesh which may account for the many cases where no pathogens are identified. METHODOLOGY Stool specimens collected from diarrheal patients from three hospitals in Bangladesh during 2011 were investigated for norovirus RNA using real-time RT-PCR assay with norovirus type specific primers and probes. RESULTS Of ...
