摘要: Abstract Serum proteins from Mycoplasma gallisepticum culture medium could be detected on the organisms as a result of incubation at low pH. Only certain serum proteins, including IgG and IgM, were found, adsorption appears to depress haemagglutinating activity organisms. There was no obvious effect slide agglutination (SA) sensitivity but an incidental finding that brief acid treatment enhanced SA antigen prepared young culture.
