in this study, it has been our purpose to isolate and serotype enteropathogenic e. coli, salmonella and shigella and determine their resistance to antibiotics. 502 swab specimens were collected during mid-july to midnovember. 1986. from two children's hospitals in tenran. from 502 cultured specimens. 108 specimens were positive for salmonella. shigella and enteropathogenic e. coli. corresp...

Ostrich (Struthio camelus) chicks less than 3 mo age are observed to experience a high mortality rate that is often associated with enteritis. This study was undertaken to investigate the infectious bacteria implicated in ostrich chick enteritis. Postmortems were performed on 122 ostrich chicks aged from 1 d to 3 mo and intestinal samples were subjected to bacterial culture. Bacterial isolates ...

Cranberry-derived compounds, including a fraction known as proanthocyanidins (PACs) exhibit anti-microbial, anti-infective, and anti-adhesive properties against a number of disease-causing organisms. In this study, the effect of cranberry proanthocyanidins (CPACs) on the infection of epithelial cells by two enteric bacterial pathogens, enteropathogenic Escherichia coli (EPEC) and Salmonella Typ...

Enteropathogenic Escherichia coli and enterohemorrhagic E. coli cause an inflammatory colitis in human patients characterized by neutrophil infiltration, proinflammatory cytokine expression, and crypt hyperplasia. Citrobacter rodentium causes a similar colitis in mice and serves as a model for enteropathogenic E. coli infection in humans. C. rodentium induces systemic T-cell-dependent antibody ...

Introduction. Since 2013, European soldiers have been deployed on the European Union Training Mission (EUTM) in Mali. From the beginning, diarrhea has been among the most "urgent" concerns. Diarrhea surveillance based on deployable real-time PCR equipment was conducted between December 2013 and August 2014. Material and Methods. In total, 53 stool samples were obtained from 51 soldiers with acu...

Young albino Swiss mice, of the NCS and NCS-D colonies, proved highly susceptible to the establishment of intestinal infection with an enteropathogenic strain of E. coli administered per os or by stomach tube. The period of highest susceptibility was rather short, extending from the day of birth to approximately 2 weeks of age. Adult NCS and NCS-D mice failed to become experimentally colonized ...

Gnotobiotic calves were inoculated with an O5:K4:H-, urease-positive strain of Escherichia coli isolated from a 2-day-old calf with diarrhea. The calves developed elevated temperatures and passed loose mucoid feces, with or without blood. The E. coli strain was negative for heat-stable and heat-labile enterotoxins but produced high levels of Shiga-like toxin. Bacteria attached diffusely to the ...

A study on the distribution patterns of enteropathogenic bacteria polluting the shoreline in Natal, Rio Grande do Norte, Brazil, was carried out based on 72 samples obtained from three storm sewers and adjoining beach locations, Praia do Meio (PM), Areia Preta (AP) and Ponta Negra (PN). From each location, 12 water samples were taken and analyzed for fecal coliforms (FC) and Escherichia coli. I...

We conducted a survey to identify the intestinal parasites and enteropathogenic bacteria involved in episodes of diarrhea in the James Bay (Quebec) Cree, a previously unsurveyed area of Canada. 382 stool samples obtained from a random sample of the population were examined; 29.3% were positive for at least one parasite and 21 different serotypes of enteropathogenic Escherichia coli (EPEC)were i...
