We studied microorganisms associated with infant diarrhea in a group of 256 children admitted to a public pediatric hospital in Montevideo, Uruguay. Diagnostic procedures were updated to optimize detection of potential pathogens, which were found in 63.8% of cases, and to be able to define their characteristics down to molecular or antigenic type. Coinfection with two or more agents was detecte...
As part of a study to determine the effects of water filtration on the incidence of community-acquired gastroenteritis in Melbourne, Australia, we examined fecal samples from patients with gastroenteritis and asymptomatic persons for diarrheagenic strains of Escherichia coli. Atypical strains of enteropathogenic E. coli (EPEC) were the most frequently identified pathogens of all bacterial, vira...
Of 210 children 164 (78%) had diarrhoea due to E.coli infection. The common enteropathogenic serotypes in 71 cases were 0111: K58 (36.6%) and 0125:K70 (25.4%). Enteropathogenic strains of E.coli were sensitive to Ampicillin (84.5%), Amoxil (73.2%) and Ampiclox (54.9%) (JPMA 36: 14, 1986). INTRODUCTION Diarrhoea is a common disease of infants and children under the age of two years. It is caused...
Background: Atypical enteropathogenic Escherichia coli (aEPEC) is regarded as a globally emerging enteropathogen. aEPECs exhibit various level of resistance to a range of antibiotics, which is increasing alarmingly. The present study investigated the antimicrobial resistance of aEPEC isolates recovered from diarrheal patients, healthy carriers, animals, and raw meats. Results: Among 267 aEPEC i...
Some clinical isolates of enteropathogenic Escherichia coli (EPEC) lack bundle-forming pili and are termed atypical EPEC. The aim of this study was to determine if atypical EPEC are pathogens by comparing the clinical features of patients infected with atypical EPEC with those of children infected with other causative agents of diarrhea. Fecal samples obtained from children attending the Royal ...
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...
Enteroinvasive Escherichia coli (EIEC) causes dysentery; however, it is less widely reported than other etiological agents in studies of diarrhea worldwide. Between August 2003 and July 2005, stool samples were collected in case-control studies in 22 rural communities in northwestern Ecuador. Infection was assessed by PCR specific for LT and STa genes of enterotoxigenic E. coli (ETEC), the bfp ...
Strains of Escherichia coli isolated from systemic infections of humans exhibited marked intraperitoneal and intracerebral virulence for mice. This marked virulence was not exhibited by enteropathogenic strains.
The alkaloids from the ethanolic extract of H. antidysenterica seeds were evaluated for their antibacterial activity against clinical isolates of enteropathogenic Escherichia coli (EPEC) in vitro, and their antidiarrhoeal activity on castor oil-induced diarrhoea in rats, in vivo. The plasmid DNA, whole cell lysate and outer membrane protein profile of a clinical isolate of EPEC was determined i...
