Abstract
The presence of asymptomatic individuals infected with Mycoplasma agalactiae (Ma),the main causative agent of contagious agalactia (CA), in small ruminant herds imply anepidemiological risk regarding the transmission of this disease. The aim of the presentwork was to detect asymptomatic rams infected with Ma in different artificial inseminationcentres of an endemic area of CA, and to determine the most effective sample to identifythese individuals. For this, different samples (auricular and nasal swabs, together withsemen and serum) were taken from 215 rams, 37 (17.2%) of which tested positive to Ma.The specimens which proportionally yielded the greatest number of positive results weresemen samples (13.6%), followed by nasal swabs (5.8%), whereas auricular swabs andserology resulted insufficient to effectively detect infected rams. These results highlight theneed to implement specific measures to avoid the admission and presence of rams infectedwith Ma in artificial insemination centres in order to reducing the risk of transmitting CA.
