Result of biochemical characteristic test and developing some seed indexes of MG bacteria for antigenic production

Abstract

Result of this study indicated that the isolated MGGC8 bacteria strain was met some seed indexes using for antigenic production as follows:- High adaptation and stability in 7day old chicken embryos. Infection result showed that MGGC8 was able to kill chicken embryos with the typical lesions, the amount of concentrated dead embryos after 48-96 hours of infection was similar to that of the MGS6 standard strain.- Stable development on different culture media and having agglutination reaction with standard antiserum, serotype A.- Tested result by biological reactions:+ All of the strains fermented glucoza and TTC (100%), none of them metabolized Arginine and PHO.+ All of the strains have given the positive result when using PCR technique. The MG product obtaining on Agarose gel was 530 bp.
