Current question of the control of Mycoplasma synoviae infection
2000
Stipkovits, L.
Mycoplasma synoviae infection is widespread both abroad and in Hungary because of the varability of strains in the Mycoplasma species. Some strains have decreased virulence in layers. For this reason breeding companies do not stress eradication of M.synoviae infection from their breeding stocks. On the other hand variant strains show a significant virulence for broiler chickens and broiler breeders, especially in combination with some virus infections (e.g. infectious bronchitis). Organotropism of variant strains has changed also in the last few years; M.synoviae infection causes no synovitis but respiratory disease.
