title: Comparison of antigens of pneumonia-associated mycoplasma species by gel diffusion.
abstract: Comparison of fluorocarbon-extracted antigens of six mycoplasma species by double immunodiffusion and counterimmunodiffusion techniques revealed a close reciprocal relationship among Mycoplasma dispar, M. ovipneumoniae, and M. hyopneumoniae. A lesser degree of cross-reaction was also demonstrated between these three species and M. hyorhinis and M. bovoculi. The interrelationships were more clearly demonstrated by double immunodiffusion than by counterimmunodiffusion.
