[Counterimmunoelectrophoresis in the diagnosis of infectious epididymitis in rams].

Both the 'counter' immunoelectrophoresis method and the complement-fixation test were employed to study a total of 767 samples of blood sera taken from rams. Five-hundred and seventeen of these were taken from ram flocks in which the infection was recorded by the clinical and the bacteriological method and the remaining 517 samples were taken from rams of intact flocks. A comparative evaluation was made of the two methods for the diagnosis of the disease when the animals were alive. Results made it clear that the 'counter' immunoelectrophoresis method was advantageous and could be used as a perspective adjunct in diagnosing the disease.
