coli O157 are the production of Shiga toxin 2 and the adhesin intimin. The role of some of the other virulence factors, such as enterohaemolysin, a serine protease (EspP) and a catalase/peroxidase (Katp), in infection may be low. Uncharacterized virulence properties such as a clostridial-...
Virulence factors of E. coli can affect a wide range of eukaryotic cellular processes, including cell signalling, ion secretion, protein synthesis, mitosis, cytoskeletal function and mitochondrial function. Virulence factors of pathogenic E. coli are frequently encoded on genetic elements such as plasmid...
Escherichia colithat are capable of causing human disease are often classified into pathogenic variants (pathovars) based on their virulence gene content. However, disease-associated hybridE. coli, containing unique combinations of multiple canonical virulence factors have also been described. Such was the...
Virulence factors in Escherichia coli strains isolated from Swedish piglets with diarrhea. Parenteral vaccination of sows against Escherichia coli diarrhea in their newborn piglets has become more common during the last decade in Sweden, and the ... O Söderlind,B Thafvelin,R Möllby - 《Journ...
For the other virulence-related genes a high level of diversity is observed, demonstrating that all stages of the infection can be mediated by a number of alternative virulence factors. The variable profile of virulence genes in septicemic E. coli strains, as well as a prevalence of mobility-...
The diagnosis of EPEC is confirmed by PCR or DNA probes for the genes encoding for particular adherence virulence factors, such as the eae gene or bfpA gene. Enterohemorrhagic E. coli Enterohemorrhagic E. coli (EHEC) are similar to EPEC (see above) although they lack BFP; in addition to th...
Escherichia coli Phylogenetic group Virulence factors Antimicrobial resistance Bovine mastitis 1. Introduction The dairy cow is becoming a major economically important animal throughout the world, and Escherichia coli is one of the important pathogens associated with bovine mastitis. Mastitis caused by E....
Prevalence of virulence factors of Escherichia coli strains isolated from diarrheic and healthy piglets after weaning. Osek J. Prevalence of virulence factors of Escherichia coli strains isolated from diarrheic and healthy piglets after weaning. Vet Microbiol. 1999; 68: 209... J Osek - 《Veterinary...
et al. A specific genetic background is required for acquisition and expression of virulence factors in Escherichia coli. Mol. Biol. Evol. 21, 1085–1094 (2004). This paper indicates the important role of the genetic background in the emergence of virulent E. coli clones at the species ...
receptor (67LR)15,16. However, the physiological roles of these interactions in the context of bacterial meningitis remain to be established. Identification of the host receptors recognizingE. colivirulence factors is still an open question.
