A successful infection of the human intestine by enteropathogenic bacteria depends on the ability of bacteria to attach and colonize the intestinal epithelium and, in some cases, to invade the host cell, survive intracellularly and disseminate from cell to cell. To accomplish these processes bacteria have evolved an arsenal of molecules that are mostly secreted by dedicated type III secretion s...

In this digital era, machine learning is a technology that in demand by organizations and individuals. the age of data information, ability to process efficiently needed. As amount grows, there are various problems learning. One them with increasing data, class imbalance also often found. Class condition where dominates another class, one example case when positive value has less number than ne...

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 ...

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.

Uropathogenic organisms have evolved numerous defense mechanisms against antimicrobial agents, hence resistance to old and newly available drugs are increasing at an unprecedented level. The events of antibiotic resistance have lead for screening of several medicinal plants for their potential antimicrobial activity. The aim of this study was to evaluate the antimicrobial efficacy of Cyminumcum...
