Biological and serological comparison of two embryo-lethal mycoplasmas isolated from turkeys

Two uncharacterised, independently isolated, embryo-lethal mycoplasmas obtained from turkeys and designated W8 and CT were compared with each other and with a third, culturally similar, embryo-lethal turkey mycoplasma, Iowa 695, by cultural and serological methods. The three mycoplasma isolates were serologically distinct and CT could be differentiated from W8 by its ability to reduce 2,3,5-triphenyltetrazolium chloride under aerobic conditions.
