The lesion distribution in males appears more restricted, with consistent lesions being noted in the prostate gland and epididymis.
Correspondingly, the prostate also appears to be the most reliable tissue for bacterial isolation. Differences in the lesion distribution between males and females have not been well characterized, and it is possible that these differences relate to the differences in blood-culture results seen between the male and female dogs in this group. Fetal lesions were unremarkable, despite isolation of B. canis from the liver and lung.
