Impact of Nosema ceranae and Paenibacillus larvae on Gut Bacterial Communities of Western Honey Bees Apis mellifera Linnaeus, 1758

| 總結: | In Thailand, apiculture is mostly located in northern region. The honey bee, Apis
mellifera, is critical for the pollination of many economically important crops. There are
various factors contributing to honey bee decline including microbial pathogen. Nosema
disease and American Foulbrood disease are the most microbial pathogens propagating
their function in gut of honey bee. This study investigates the impact of gut propagation
pathogens including P. larvae and N. ceranae on bacterial communities in gut of
A. mellifera using 454-pyrosequencing. Pyrosequencing results showed that N. ceranae
play an important role elimination of Microvirgula and Pseudomonas in adult honey
bee gut while P. larvae infecting larvae had a considerable effect on the decrease of
Gluconacetobacter. On the other hand, Pseudomonas was found only in the gut of
P. larvae larvae. The results indicated that P. larvae and N. ceranae have an impact on
some bacteria in gut of A. mellifera, not only by elimination of gut bacteria but also
allowing some bacterial infection in honey bee gut. However, these pathogens did not
effect on dominant bacteria in bee gut. |
