ABSTRACT: The present study aimed to investigate contagious agalactia (CA) in flocks from Pernambuco State. The study involved 225 goats and 63 ewes; 288 milk samples and 100 vaginal swabs were collected in total. The PCR assays were carried out using specific primers to Mycoplasma agalactiae and the Mycoplasma mycoides cluster. Among the goat’s milk samples,12.0% (27/225) were positive for Mycoplasma agalactiae DNA, while 5.3% (12/225) contained the Mycoplasma mycoides cluster. Of the vaginal swabs taken from goats, 15.4% (12/78) were positive for Mycoplasma agalactiae DNA and 3.8% (3/78) contained the Mycoplasma mycoides cluster. In the case of ewes, 4.3% (1/23) of the milk samples contained Mycoplasma agalactiae DNA, and 7.5% (3/40) were positive for the Mycoplasma mycoides cluster. Vaginal swabs taken from sheep´s were negative. Analysis of risk factors for mycoplasmosis, showed that goats and sheep flocks on the extensive breeding system are more likely to have mycoplasmosis than those on the intensive breeding system (odds ratio (OR) 6.2; p=0.004); meat goat and sheep flocks are more likely to have infection compared to dairy flocks (OR 4.8; p=0.011); unclean animal housing increases the chances of infection (OR 5.0; p=0.031) and not performing quarantine increases the chances of mycoplasmosis (OR 4.6; p=0.042). Based on these findings we conclude that CA syndrome in the semiarid region of Pernambuco state can be associated with Mycoplasma agalactiae and Mycoplasma mycoides cluster.
