Histopathology of representative placental samples from bovine abortions positive by real-time PCR for: Coxiella burnetii (a), Chlamydia abortus (b) and pathogenic Leptospira spp. (c). Infection with either C. burnetii (a) or C. abortus (b) was characterized by variable degrees of vasculitis (arrow) and necrosis (arrowhead). Cases positive for pathogenic Leptospira spp. by real-time PCR (c) showed variable severities of necrosis (arrowhead) and lacked vasculitis. HE, bar 100 μm
