New study “A Pediococcus strain to rescue honeybees by decreasing Nosema ceranae- and pesticide-induced adverse effects” by Peghaire et al. found that feeding live Pediococcus bacteria can rescue honeybees from N. ceranae– and pesticide adverse effects. Mortality was down from 41% to 15% and Nosema spores per bee decreased by 80%. Gene expression analysis indicates that the bacteria can achieve this benefit by stimulating the honeybee immune and detoxication systems.
Nosema infection threatens millions of honeybee colonies worldwide. Direct-Fed Microbials (DFM), also called probiotics, help bees overcome Nosema infection.
