Bacterial pathogens deliver multiple effector proteins into eukaryotic cells to subvert host cellular processes and an emerging theme is the cooperation between different effectors. Here, we reveal that a fine balance exists between effectors that are delivered by enteropathogenic E. coli (EPEC) which, if perturbed can have marked consequences on the outcome of the infection. We show that absen...

Enteropathogenic Escherichia coli grow as discrete colonies on the mucous membranes of the small intestine. A similar pattern can be demonstrated in vitro; termed localized adherence (LA), it is characterized by the presence of circumscribed clusters of bacteria attached to the surfaces of cultured epithelial cells. The LA phenotype was studied using B171, an O111:NM enteropathogenic E. coli (E...

Enterotoxigenic Escherichia coli (ETEC) that were isolated from neonatal pigs and that did not react in preliminary tests for pilus antigen K88 were subjected to additional tests for K88 and for pilus antigens K99 and 987P. Four such isolates produced K88, 9 isolates produced K99, 55 isolates produced 987P, and the remaining 43 isolates produced none of the three pilus antigens (3P(-)). Immunof...

Different composites based on ZnO/Ag3PO4 and ZnO–malachite (Cu2(OH)2CO3) were synthesized in order to determine their effectiveness the treatment of municipal industrial wastewaters (mainly polluted by enteropathogenic bacteria, dyes, heavy metals). The addition Ag3PO4 malachite did not significantly modify physicochemical properties ZnO; however, optical this oxide modified as a result its cou...

background and objectives: pathogenic strains of escherichia coli are a common cause of acute infectious diarrhea. the aim of this study was to investigate the frequency, virulence markers and antibiotic resistance patterns of diarrheagenic e. coli (dec) isolated from adolescents and adults in hamadan, west of iran. materials and methods: a total of 187 stool samples were collected from adults ...

We report the first Shiga toxin 2-producing Acinetobacter haemolyticus strain that was isolated from the feces of a 3-month-old infant with bloody diarrhea. Usual enteropathogenic bacteria were not detected. This finding suggests that any Shiga toxin-producing microorganism capable of colonizing the human gut may have the potential to cause illness.
