Koala retrovirus infection and disease in South Australian koala (Phascolarctos cinereus) populations. In Proceedings of the Second Koala Retrovirus Workshop, ed. D. E. Alquezar-Planas, D. P. Higgins, C. L. Singleton, and A. D. Greenwood

Koala retrovirus (KoRV) infection, endogenous in all northern koalas (Phascolarctos cinereus), has been found to occur at lower, but increasing, prevalence the Kangaroo Island and Mount Lofty Ranges koala populations South Australia. Proviral viral loads are also lower than Queensland koalas, which may be due exogenous spread of or related variable presence genes fragmented expression that positive koalas. However, high proviral full across KoRV genome Australian individuals with neoplasia, particularly lymphoma, can as extensive severe observed KoRV-A is predominant subtype no association chlamydial status except correlate severity chlamydiosis. Based on complexity infections further research needed understand differences transmission pathogenesis occur.
