  • Species
  • Functional genomic analysis provided data that allowed us to correlate the highly infectious nature of Aeromonas pathotypes belonging to several different species with virulence signatures and their potential ability to cause NF. (sigmaaldrich.com)
  • Similar to other Proteus species, P. penneri has a cell-bound hemolytic factor, which has been shown to facilitate penetration of the organism into cultured Vero cells without any cytotoxic effects. (wikipedia.org)
  • gene
  • Transcription of hly, as well as other virulence factors of L. monocytogenes within LIPI-1, is activated by the protein encoded by prfA gene. (wikipedia.org)
  • combined A repressive effect of Fis and previously characterized negative regulatory factors could be responsible to keep the gene silenced most of the time. (wikipedia.org)
  • Salmonella
  • Fis was originally identified as the factor for inversion stimulation of the homologous Hin and Gin site-specific DNA recombinases of Salmonella and phage Mu, respectively. (wikipedia.org)
  • protein
  • prfA is thermoregulated by the PrfA thermoregulator UTR element, such that translation of prfA maximally occurs at 37 °C and is nearly silent at 30 °C. Since 37 °C is within the range of normal body temperature, PrfA protein, as well as listeriolysin O and other virulence factors regulated by PrfA, is only produced when L. monocytogenes is in a host. (wikipedia.org)
  • type III se
  • Many virulence determinants of E. amylovora have been characterized, including the Type III secretion system (T3SS), the exopolysaccharide (EPS) amylovoran, biofilm formation, and motility. (mdpi.com)
  • host
  • A PEST-like sequence is present in LLO and is considered essential for virulence, since mutants lacking the sequence lysed the host cell. (wikipedia.org)
  • role
  • To investigate the potential role of the Ave1 homologs in virulence, a V. dahliae Ave1 deletion mutant was complemented with the Ave1 homologs of Fusarium, Cercospora and Colletotrichum, and tested for full aggressiveness on tomato. (wur.nl)
  • various
  • Here, we evaluate whether the various pathogen-derived Ave1 homologs are virulence factors. (wur.nl)
  • This phenotype mimics an effect produced by hepatocyte growth factor which may participate in various aspects of cancer, including metastasis. (wikipedia.org)
