| Summary |
Antigens of opxnlernent-fixation (Cfl, indirect henagglutination (NA), and agar gel precipitation (AGP) were preparer! from Mycoplasma bovirhinis, M. dispar, M. sp. group? and Aclioleplasma laidlawii isolai in Taiwan. The reaction of these antigens the corresponding serum were high-sthfic.
Titrations of antibdies against Mycoplasma spp. with these preparM antigens were marie from the fan cattle.

Ths stiy indicated that IRA and CF tests were more sensitive than AGP, and NA was theIsting&tice.
