Pathogenic Yersinia translocates effector proteins into target cells via a type III secretion system (TTSS), modulating the host immune response. A component of the TTSS translocon, LcrV, has been implicated in preventing inflammation through Toll-like receptor 2 (TLR2) by inducing expression of the anti-inflammatory cytokine interleukin-10 (IL-10). TLR2(-/-) mice were reported to be less susce...

UNLABELLED Enteropathogenic Escherichia coli may cause diarrhoea in infancy, but it is not routinely detected and regarded as a major causative agent. The aim of the present study was to estimate the incidence of enteropathogenic E. coli infection and to investigate its epidemiology and pathogenesis from faecal specimens in infants hospitalized for acute gastroenteritis. Between March 2008 and ...

⎯In this paper we investigate the capability of the genetic programming approach for producing hierarchical, rule-based, classification trees. These trees can be seen as an extension to the machine learning decision trees concept, where the predicates here can be complex expressions rather than just simple attribute-value comparisons. In order to improve the search ability and to produce meanin...

A one hundred and twenty specimens (frozen chickens) were gathered from various companies sources at sites in Iraq. the aim of this study to detect virulence gene isolated Ecoli frozen chicken meat shops Iraq investigate distribution antibiotics resistance against papC E coli. The result shows that( n,%) 15, 45 ,33,100, 2,6 , 20, 60.6 26,78.7 % out 33 isolate positive for pap C gene, jutA neuC ...

Immunodiffusion experiments were conducted to associate a precipitin line with Escherichia coli heat-labile enterotoxin (LT). Wild strains of porcine and of human enteropathogenic E. coli as well as laboratory-derived enterotoxigenic variants of E. coli K-12 were used for LT antigen preparations. These were produced mainly by ultrafiltration and ammonium sulfate precipitation of broth culture s...

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...

Virulent M protein-containing strains of Streptococcus pyogenes were found to adhere well to human pharyngeal cells in vitro. In contrast, an avirulent M - strain and an enteropathogenic Escherichia coli strain adhered feebly. When various rat tissues were exposed to mixtures of a virulent S. pyogenes strain and an enteropathogenic E. coli strain, the relative proportions of the two pathogenic ...
