Glucose-dependent Secretion and Destruction of Hydrogen Peroxide by Mycoplasma pneumoniae

RESUMO
The secretion of H2O2 by Mycoplasma pneumoniae and M. gallisepticum was measured with the new catalase-aminotriazole method. Peroxide secretion by the mycoplasmas was stimulated by glucose. When catalase and aminotriazole were omitted and exogenous H2O2 was added to the mycoplasmas, a loss in H2O2 was noted with time; the addition of glucose speeded the disappearance of H2O2. The presence of this peroxidase-like activity in the mycoplasmas explains an observed failure of H2O2 to accumulate freely in the suspension medium.
