Abstract
The presence of asymptomatic infected carriers of Mycoplasma agalactiae (Ma) in smallruminant herds is a risk regarding the spread of contagious agalactia. Contrary to goats,chronical infection and systemic dissemination of Ma in naturally infected sheep havenot yet been characterized. The aim of this study was to detect Ma at different anatomiclocations of asymptomatic infected rams. For this, 8 rams were necropsied and samplesfrom different organs were taken and analysed by PCR. Of the 280 specimens, 49 (17.5%) tested positive to Ma. This pathogen was most frequently detected in the respiratory(42.25%), nervous (40%) and genitourinary (13.48%) systems. Moreover, compatiblehistopathological lesions were found in the respiratory system. These results demonstratefor the first time the ability of Ma to colonize distant anatomic regions in infected rams.
