Study: Shared Water Sources Contribute To EHV Transmission Sponsored by:
A study has found that equine herpesviruses are able to replicate in freshwater sources in the wild and remain infectious to spread among animals, especially during drought conditions. In the wild, many species of animal will congregate around freshwater sources to drink, potentially allowing for virus transmission between species.
Drs. Anisha Dayaram, Peter Seeber, Alexandre Courtiol, Sanatana Soilemetzidou, Kyriakos Tsangaras, Mathias Franz, Gayle McEwen, Walid Azab, Petra Kaczensky, Jörg Melzheimer, Marion East, Oyunsaikhan Ganbaatar, Christian Walzer, Nikolaus Osterrieder and Alex Greenwood sampled water holes in areas of Africa and Mongolia that had significant dry seasons. They determined that EHV can remain stable and infectious in water under these conditions.

Retroviruses are re-writing koala genome and causing cancer
Koalas are facing multiple environmental and health issues which threaten their survival. Along with habitat loss – accelerated by last year’s devastating bush fires – domestic dog attacks and road accidents, they suffer from deadly chlamydial infections and extremely high frequency of cancer.

An international team of scientists led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) now demonstrate that a retrovirus invading the koala germline explains the high frequency of koala cancer. The results are reported in the journal Nature Communications.
The koala retrovirus (KoRV) is a virus which, like other retroviruses such as HIV, inserts itself into the DNA of an infected cell. At some point in the past 50,000 years, KoRV has infected the egg or sperm cells of koalas, leading to offspring that carry the retrovirus in every cell in their body. The entire k
