M. hyosynovia and M. hyorhinis are species of Mycoplasmas. They produce syndromes similar to Glasser's disease with milder expression, rarely menigitis and arthritis.

M. hyorhinis causes a chronic progressive polyserositis in pigs under 10 weeks old resulting in a fever, laboured breathing, lameness and swollen joints. Serofibrinous pleurisy, pericarditis and peritonitis occur. Treatment includes tylosin and lincomycin.
