The objective of this study was to detect Brucella abortus and injuries caused by the bacteria in fetal membranes and fetuses. Twenty buffaloes serologically positive for brucellosis were used and subjected to stamping for collection of material from the closed uterus of several months gestation. Fetal age was determined by ultrasound examination and the size of fetuses was measured at necropsy. The samples were subjected to histopathology and qPCR. From the second month of pregnancy on it was possible to detect the presence of B. abortus DNA in amniotic fluid, allantoic liquid and uterus, and from the fifth month on in placenta, heart, spleen, kidney, lung, intestine, liver and lymph nodes of the fetuses. The main pathological findings were fibrinous suppurative necrotic placentitis, and chronic endometritis. |
