parahaemolyticus are associated with pathogenicity: thermostable direct hemolysin (tdh) and thermostable direct hemolysin-related hemolysin (trh) (Nishibuchi et al.
coli virulence factor hemolysin induces neutrophil apoptosis and necrosis/lysis in vitro and necrosis/lysis and lung injury in a rat pneumonia model.
The pathogenicity of this group is due to several factors include adhesins, hemolysin secretion, serum resistance and biofilm creation.
Several PCR assays were used to detect the following 12 staphylococcal virulence genes including the pvl genes (lukF/S-PV), the staphylococcal enterotoxin genes (sea, seb, sec), the exfoliative toxin genes (eta, etb), the hemolysin genes (hla, hlb), the adhesion factor genes (fnbA,fnbB, clfa), and the toxic shock syndrome toxin (tst).
Such pores do exist, both in the form of naturally occurring or slightly modified protein porins (such as human hemolysin or Mycobacterium smegmatis porin A), or various controlled synthesis solid state materials including metals, metal alloys, and carbon nanotubes.
haemolyticus produce a hemolysin, cytolysin and enterotoxin and able to form biofilms and often shows highest level of antibiotic resistance among the CoNS, which makes these infections difficult to treat.
A second toxin, Hemolysin, can also be produced, causing severe tissue death at the site of infection.
This patent broadly claims composition of matter for antibodies that cross-neutralize Staphylococcus aureus alpha hemolysin and up to four additional S.
It is also known that T6SS secretes hemolysin and the effector protein VrgG, both of which are present in the C.
parahaemolyticus typically carry the thermostable directed hemolysin (tdh) gene or tdh-related hemolysin(trh) gene or both genes simultaneously [17, 18].
