Current questions of the control of Mycoplasma synoviate infection
2000
Stipkovits L.
Mycoplasma synoviae infection is widepread both abroad and in Hungary because of the variability of strains in this Mycoplasma species. Some strains have decreased virulence in layers. For this reason breeding companies do not lay stress on eradication of : 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. infections bronchitis). Organotropism of variant strains has changed also in the last few years; M. synoviae infection causes no synovitis but respiratory disease.
