Mycoplasmacidal activity of peroxidase-H2O2-halide systems
Abstract
A mycoplasmacidal system consisting of myeloperoxidase (MPO)-containing granules, H(2)O(2), and a halide is described. In all parameters measured, it appears to be identical to the MPO-H(2)O(2)-halide bactericidal system previously reported. It has a pH optimum of approximately 5.5 and an optimal MPO:H(2)O(2) ratio of 1:25. The halide requirement can be satisfied by either chloride or iodide. Through the use of taurine or horseradish peroxidase substitution, chloride-mediated killing can be distinguished from iodide-mediated killing. The relationship of this mycoplasmacidal system to other mycoplasmacidal systems and to host surveillance of mycoplasma is discussed.
