It is with regret that we report that the humanitarian, geneticist, and scientist, Professor Warwick Kerr, passed away this morning, September 15, 2018. He was six days past his 96th birthday.  Dr Kerr, a Brazilian bee scientist, had one of the most maligned lives of any research scientist. He will be remembered by some as the man who gave us ‘Killer Bees’ – the African-European bee known for its (sometimes) aggressive behaviour. The Africanized Honey Bee, a hybrid which Dr Kerr was largely responsible for creating, helped turn his impoverished homeland of Brazil from a backwater of agriculture and honey production into one of the most prolific honey and agriculture countries in the world.

A Potential New Tool in the Battle Against a Bee-Killing Bacteria by Meredith Swett Walker

American foulbrood is a bacterial disease afflicting honey bee (Apis mellifera) colonies. The Paenibacillus larvae bacterium germinates in the gut of a honey bee larva; dead larvae often decompose into a brown, gooey substance. New research suggests certain analogs to a molecule called indole may be useful in blocking the bacteria’s germination. (Photo credit: Wikimedia Commons/Tanarus, CC BY-SA 3.0)

 

It’s a beekeeper’s nightmare: She lifts the lid on her carefully tended hive and is greeted with a whiff of rotting flesh. Further inspection finds that the young bees of the colony, who should be plump, pearly-white larvae, have melted into a puddle of brownish goo at the bottom of their cells. This colony is infected with American foulbrood disease—most likely a death sentence.

If she’s very lucky, she may be able to save the colony with a course of antibiotics, but the drugs don’t always work, and the disease is highly contagious. To save nearby colonies from infection, the beekeeper may be required burn the entire hive, bees and all.

American foulbrood disease, or AFB, is caused by the Paenibacillus larvae bacterium, a difficult-to-control and highly destructive pathogen found worldwide. In a study published last week in the open-access Journal of Insect Science, Israel Alvarado, Ph.D., and colleagues at the University of Nevada, Las Vegas (UNLV), explore whether blocking the germination of P. larvae spores is an effective way to treat this infection.
