Abstract

Mycoplasma gallisepticum (M.G.) infection in poultry
can result in severe economic losses. During last few
years many types of drugs and control measures were
used for M. gallisepticum (Chalquest and Fabricant,
1959; Barnes et al., 1960; Levine and Fabricant,1962;
Olson et al., 1962, while others used live vaccine
(Luginbuhl et al., 1967, Zuzuki et al., 1971; Jordane
et al., 1981; Chnabra and Goel, 1982 and Glisson and
Kleven, 1983) as a method of control. Also many others
as Adler et al. (1960); Adler and Da Silva (1970) ;
Takemitsu et al. (1970), and Kuniyasu and Yoshida
(1971) attempted to obtain protection by Killed M.G.
either by plane vaccine or by vaccine with adjuvant.
Most reports concerning M.G. vaccines are contradi-
ctory, thus the aim of this investigation was to
evaluate the efficiency of inactivated Mycoplasma
gallisepticum in protection of chickens at various
ages against experimental infection with virulent
M.G.S¢ strain in Egypt.
