title: Estimation of Mycoplasma pneumoniae inoculum size by rate of tetrazolium reduction.
abstract: The rate of appearance of red-colored formazan indicating reduction of 2,3,5,-triphenyltetrazolium chloride by Mycoplasma pneumoniae was dependent on the inoculum size. The test permits estimation of M. pneumoniae cells in preparations that cannot be counted by dilution methods.
