Mycoplasmacidal activity of peroxidase-H2O2-halide systems. 1972

A A Jacobs, and I E Low, and B B Paul, and R R Strauss, and A J Sbarra

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.

D009174	Mycoplasma	A genus of gram-negative, mostly facultatively anaerobic bacteria in the family MYCOPLASMATACEAE. The cells are bounded by a PLASMA MEMBRANE and lack a true CELL WALL. Its organisms are pathogens found on the MUCOUS MEMBRANES of humans, ANIMALS, and BIRDS.

D010544	Peroxidases		Ovoperoxidase
D010944	Plants	Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE.	Plant
