A mycoplasma meleagridis haemagglutination inhibition test

Prevention of egg transmission and heterogeneity among isolates of Mycoplasma meleagridis

“…Some resulted in HI titers as high as 1:320, while others were negative though they were all positive in the plate and tube agglutination tests. This is in contrast to Thornton et al (1975) who found the HI test to be sensi tive and specific and they used it successfully in M. meleaqridis eradication programs.…”

“…Although Rhoades (1969b) found his Eg strain to have good hemagglutinating activity, Thornton et al (1975) failed to detect hemagglutination using Rhoades Eg strain. In the present study it was also found that Eg failed to cause hemagglutination.…”

“…Yamamoto et al (1965a) studied many isolates and found only one which possessed hemagglutinating activity. Recently additional haemagglutinating strains have been reported in the U.S.A. (Rhoades, 1969b) and in Britain (Thornton et al. 1975).…”

“…A hemagglutination inhibition test also has been developed and reported to be more effective than the agglutination test in detecting antibodies to M. meleagridis infection (Rhoades, 1969b;Thornton et al 1975). …”
