Influenza B viruses with lower antiviral sensitivity reported
Mar 29, 2011 (CIDRAP News) – North Carolina health officials have reported a number of influenza B isolates with reduced sensitivity to oseltamivir (Tamiflu), a rare finding, but they say antivirals remain effective and there is no reason for clinicians to change their prescribing practices.
N.C. flu strain less affected by Tamiflu

State and federal public health officials are examining a cluster of influenza B viruses from North Carolina that appear to be less responsive to a common antiviral drug than typical flu viruses.
Viral replicase points to potential cancer therapy
Alpha viruses, such as Sindbis virus, carry their genetic information on a single strand of RNA. They use a protein, replicase, to produce double stranded RNA (dsRNA) inside infected cells, which initiates the host's immune response. New research demonstrates that an artificial plasmid coding for the replicase genes of Sindbis virus causes regression and destruction of lung cancer, or melanoma ...
Beware: Virus-Eating Virus Discovered in Antarctica
While scientists labor to find a cure for AIDS, the common cold, and other viruses, researchers in Antarctica have unearthed a life form capable of defeating our most infectious foes. And--surprise!--it's another virus. No really--it's not the pitch for some direct-to-video cheesy sci-fi movie. The virus, dubbed "Organic Lake Virophage" or OLV, was discovered in the Organic Lake, [...]
