Transcriptional regulation of the ilv-leu operon of Bacillus subtilis.

abstract：:Seventeen strains of mycoplasmata representing 11 named species were compared serologically by three parameters: growth inhibition on agar, double immunodiffusion, and complement fixation. In growth-inhibition studies, a strain labeled Mycoplasma histotropicum was found related to and perhaps best classified as M. pul...
