title: [Complement fixation reaction studies in rhinopneumonitis of horses].
abstract: It was established that the complement binding reaction (CBR) is a suitable and very fast method for horse rhino-pneumonitis diagnostics. Cell cultural virus produced in cell cultures of pig kidneys was used as antigen. The antigen lots tested have no anticomplementary properties. Highest complement binding activity was evident in the non-diluted antigen, which discovered specific antibodies in immune serums. The CBR specificity was tested by the aid of homologous and heterologous serums and antigens. The titers of complement binding antibodies in the serums of 255 horses recovered from the disease varied from 1:10 to 1:320, and in some cases even to 1:640. The blood samples investigated were from studs having rhinopneumonitis proven by clinical observations, by virus neutralizing reaction and by virus isolation. In almost all animals under study neutralizing and complement binding antibodies were established simultaneously.
