  • it is conceivable that this strain is not as widely distributed and is less pathogenic than other SGs, especially SG 1. (blogspot.com)
  • suggests that HGA may help L. pneumophila bacteria to persist in biofilms, but more work needs to be done to test this idea. (elifesciences.org)
  • As a result, pathogenic bacteria can persist and multiply in this environment. (alvimcleantech.com)
  • Next, Dr. Kimberly Decker shared her interests in identifying the mechanisms of virulence gene regulation by pathogenic bacteria. (nih.gov)
  • Instead, L. pneumophila cells secrete HGA only when they are conditionally HGA-resistant, which allows these bacteria to produce a potentially self-toxic molecule while restricting the opportunity for self-harm. (elifesciences.org)
  • Unexpectedly, L. pneumophila was not always resistant to HGA, despite secreting large quantities of this molecule. (elifesciences.org)
  • L. pneumophila delivers a large number of proteins, so called effectors, into the host cell via the Dot/Icm type IV secretion system (T4SS). (nih.gov)
  • Moreover, the morphological differences were observed between L. pneumophila cultured either with Willaertia or other amoebae. (nih.gov)
  • We find that L. pneumophila sensitivity to HGA is density-dependent and cell intrinsic. (elifesciences.org)
  • Electron microscopy demonstrated that the formation of numerous replicative phagosomes observed within Acanthamoeba and Hartmannella is rarely seen in W. magna c2c cocultured with L. pneumophila. (nih.gov)
  • Many bacteria, both environmental and pathogenic, exhibit the property of autoaggregation. (aimspress.com)
  • Instead, L. pneumophila cells were only resistant to HGA when the bacteria were living in crowded conditions. (elifesciences.org)
