Interferon was induced in mice after intraperitoneal inoculation with four different mycoplasmas. Peak levels of between 100 and 300 U of interferon per ml were attained by 6 h postinfection with each of the mycoplasmas except Mycoplasma arthritidis, which induced higher titers (400 to 11,800 U/ml) by this time. A fifth mycoplasma, M. pulmonis, induced interferon inconsistently and at a later (72 to 96 h) time. Mycoplasmatales virus MVL51 and sterile mycoplasmal broth did not stimulate interferon production in vivo. All of the mycoplasmas and MVL51 failed to induce interferon in murine spleen cell, peritoneal exudate cell, or peripheral blood leukocyte cultures. Preinfecting the mycoplasmas with MVL51 or treating the organisms with trypsin or dilutions of specific antisera did not enhance their ability to induce interferon in vitro.
