OBJECTIVES To study bacterial contamination of fresh vegetables before cleaning and before serving to patients in 14 hospitals. MATERIAL AND METHOD Aerobic plate count was performed and emphasized on total viable aerobic bacteria, fecal coliform, fecal Escherichia coli and enteric pathogens in fresh vegetables including romaine lettuce, onion, parsley, celery and tomato before cleaning and be...

BACKGROUND AND OBJECTIVES Interaction of bacteria with the immune system within the intestinal mucosa plays a key role in the pathogenesis of inflammatory bowel disease (IBD). The aim of the current study was to develop a fluorescein-aided confocal laser endomicroscopy (CLE) method to visualise intramucosal enteric bacteria in vivo and to determine the involved mucosal area in the colon and ile...

The rpoH regulatory region of different members of the enteric bacteria family was sequenced or downloaded from GenBank and compared. In addition, the transcriptional start sites of rpoH of Yersinia frederiksenii and Proteus mirabilis, two distant members of this family, were determined. Sequences similar to the sigma(70) promoters P1, P4 and P5, to the sigma(E) promoter P3 and to boxes DnaA1, ...

Lactic acid bacteria, Bacillus species and yeasts are involved in the fermentation of cassava dough into agbelima. Microbial interactions within and between these groups of microorganisms were investigated in addition to the survival of five enteric pathogens inoculated into agbelima under various conditions. Nine out of 10 cultures of lactic acid bacteria isolated at the end of agbelima fermen...
