Abstract
Koala retrovirus (KoRV) infection, thought to be associated with lymphoid neoplasia, and Chlamydia pecorum-related ocular and urogenital disease are both highly prevalent in eastern Australian koala (Phascolarctos cinereus) populations. However, in South Australian koalas, little is known about KoRV infection and C. pecorum-associated disease. We report the first South Australian case of lymphoma in a KoRV-A-positive female koala also affected by severe reproductive chlamydiosis. The koala was from the Mount Lofty Ranges population and was presented with hindlimb lameness. Clinical examination identified right stifle crepitus, enlarged superficial lymph nodes and paraovarian cysts. Necropsy examination revealed extensive cartilage degeneration and loss over the medial femoral condyle, solid femoral bone marrow, mesenteric and ovarian tumours, paraovarian cysts and purulent metritis. Histopathology confirmed lymphoma in the bone marrow, mesenteric lymph nodes and ovary, with infiltration and parenchymal effacement in the pancreas, adrenal glands and other tissues. Lymphoma, KoRV and chlamydiosis are being investigated further in this population.
