Rey Australian koalas are currently being invaded by koala retrovirus A (KoRV-A), a virus that causes an AIDS-like immunodeficiency and makes infected koalas more susceptible to cancers and opportunistic infections such as chlamydia. Retroviruses owe their name to their replication cycle, because their RNA genomes are reverse ...

Amy joins the TWiV team to review evidence that enterovirus D68 is an etiologic agent of childhood paralysis, and her finding that the ability of the virus to infect cells of the nervous system is not a recently acquired property. Click arrow to play Download TWiV 572 (73 MB .mp3, 121 ...

Viruses that infect eukaryotic cells typically bind to a plasma membrane receptor to initiate the reproduction cycle. Attachment of bacteriophages to bacterial cells is more diverse. Some attach to bacterial outer membrane proteins, while others attach to appendages such as pili or flagella. How viruses move from the flagella to ...

The League of Extraordinary Virologists celebrate the eradication of wild poliovirus type 3, and consider the effectiveness of an influenza vaccine produced in insect cells, and how small RNAs are protecting the Koala germline from retroviral invasion.
