SUMMARY: Porcine Mycoplasma strains, previously called ‘swine enzootic pneumonia strains’ are antigenically closely related to Mycoplasma hyorhinis. Other porcine Mycoplasma strains which are culturally and antigenically distinct from M. hyorhinis are more heterogeneous and fall into four serotypes. M. granularum, however, is antigenically unrealted to these strains.
