Immuno-crossreactivity of an anti-Pichia anomala killer toxin monoclonal antibody with a Williopsis saturnus var. mrakii killer toxin.

A monoclonal antibody (mAbKT4), produced against the Pichia anomala ATCC 96603 killer toxin (PaKT) was used to detect the toxin (WmKT) produced by Williopsis saturnus var. mrakii MUCL 41968 which inhibits the growth of a PaKT-sensitive P. anomala strain MUCL 41969.
