  • In cows, mucus samples are obtained by suction, vaginal lavage, or by use of tampons, 
  • Aborted fetuses can also be examined by similar techniques, and wet preparations of the stomach contents can be examined for the organism by dark-field and phase-contrast microscopy 

Serological test is available and is used for herd screening.

It is sexually transmited, C. fetus fetus is found in the prepuce of health carrier bulls. It can survive many months in frozen semen. It can also be transmitted from bull to bull by artificial vagina. Cows do not become chronic carriers.
Risk of introduction   
Introduction could occured through importation of infected bulls or cows, semen, less likey unproperly cleaned artificial vaginal.
