This week, viruses take to the air (via creatures with wings) and a chat about herpesviruses:
Honeybees toil endlessly to make delicious delicious honey, but just like you and me, they have their off days when they don’t feel the buzz. Mites, microrganisms and viruses are enough to put pupa off their pollen, and a sick hive can suffer reduced honey production to full colony collapse. With our vested interest in their well-being, we’ve swotted up on what blights our bees, but whether the unwelcome critters in our managed hives reflect those that bug bumblebees in the wild is less understood. Things I learned from the linked article: 1) there’s some spillover of viruses from our own workers to wild bee populations, with transmission possibly occurring from sharing the same flowers, 2) bee viruses have excellent names – black queen cell virus, deformed wing virus, acute bee paralysis virus, slow bee paralysis virus and sacbrood virus.
If our bees are propagating viruses that later swarm into the wild, birds provide the opposite flight path when it comes to flu.
I think the headline “Wild birds may spread flu virus” is kind of like saying “water flows downhill”, but the article itself is a useful look into how the H5N8 and H7N7 bird flu viruses are travelling around Europe. For instance, ducks on a farm in Yorkshire in the UK may have contracted H5N8 from migratory birds from Russia. How this happens isn’t clear yet, as poultry are kept inside and wouldn’t have mixed with the wild birds.
The guys at the University of Glasgow Centre for Virus Research interview herpesvirologist Professor Peter O’Hare. A great overview of the some of the history, problems and questions associated with those ‘creeping’ viruses of humans. Whilst Peter’s lab do some cool work (this one is a recent favourite – Open Access), he doesn’t include virus latency in his list of big questions in herpesvirology! 😦 For the sake of my fragile little feelings, I’ll assume this is because we’re answering some of the questions, rather than it not being interesting…
