Abstract Introduction Colorectal cancer (CRC) is one of the most common cancers worldwide. In recent years, Artificial Intelligence (AI) and Machine Learning (ML) algorithms have gained traction in CRC research for their ability to efficiently analyse large volumes variables offer objective data driven models optimise clinical decision making. The present review provides a contemporary summary ...

BACKGROUND Enterohaemorrhagic (EHEC) and enteropathogenic (EPEC) Escherichia coli epithelial cell adhesion is characterised by intimate attachment, and attaching and effacing (A/E) lesion formation. This event is mediated in part by intimin binding to another bacterial protein, Tir (translocated intimin receptor), which is exported by the bacteria and integrated into the host cell plasma membra...

A Limulus amoebocyte lysate gel-clotting method for the determination of endotoxin in a small-volume parenteral product has been described. Sample dilution with 0.1 M potassium phosphate monobasic buffer (pH 8.0) effectively eliminated assay interference, whereas dilution with water did not. The threshold pyrogenic dose for Escherichia coli EC-2 and O127:B8 endotoxins was determined to be 1.0 n...

Although most enteropathogenic Escherichia coli strains do not produce recognized enterotoxins, we wished to examine whether they produce any factors like heat-stable enterotoxin b or cholera toxin active subunits that might be missed by conventional assay methods. E. coli strains E851 (O142) and E2348 (O127) that had caused diarrhea in volunteers were negative for heat-labile enterotoxin and h...

Escherichia coli O86 belongs to the enteropathogenic E. coli (EPEC) group, some strains of which are pathogens of humans, wild birds and farm animals. The O-antigen gene cluster of E. coli O86 was amplified by long-range PCR using primers based on the housekeeping genes galF and gnd, and then sequenced. Genes involved in GDP-Fuc and N-acetyl-galactosamine (GalNAc) synthesis and genes encoding g...

This study was conducted to characterize virulence genes of Escherichia coli isolates from water, sediment, fish, and crab in Aby Lagoon. Serogrouping was performed by EPEC antisera in 113 E. coli strains. The presence of diarrhea-associated genes (eae, stx, AggR, elt, and est) was assessed by multiplex PCR using specific primers. Based on the multiplex PCR, sixty-two isolates (42 from water, 1...

background: the purpose of this study was to find out the frequency of different serotypes of enteropathogenic es­cherichia coli (epec) among healthy/diarrheal cases. methods: a total of 191 strains, 111 from diarrheal and 80 from asymptomatic persons were examined. determination of the epec sero­groups was performed by agglutination tests using polyvalent and monovalent o antiserum. pcr-rflp a...

Abstract Purpose Bifidobacterium is an important probiotic used in food and medicine production. The properties of bifidobacteria are strain specific, so it necessary to evaluate the isolated from specific populations, especially when developing products suitable for populations. objective this study was potential safety healthy Uyghur infants northwestern China. Methods In study, antimicrobial...
