[The epizootic process in ewe lambs experimentally infected with Salmonella abortus ovis and Chlamydia psittaci var. ovis].

Studied was the dynamics of antibody production and Salmonella shedding in a flock of year-old female sheep affected with a mixed form of infection of Salmonella abortus ovis and Chlamydia psittaci var. ovis. It was established that in the presence of a mixed infection dominating was the part played by Chlamydia organisms. The apparent epizootic process with these agents usually ran its course in the later period of pregnancy, while Salmonella organisms acted by the end of the first half of pregnancy. The carrying out of a tentative serologic study during estrus contributes to revealing the state of Salmonella harbouring.
