Effect of the digestive process of the Greater wax moth (Galleria mellonella) on the causative agents of American Foulbrood (Paenibacillus larvae)

Popis výsledku v původním jazyce

Both, greater wax moth (Galleria mellonella) and the causative agent of American Foulbrood (Paenibacillus larvae) cause considerable economic losses in beekeeping practice. Their life cycle is closely related to the honey bees, thus they can easily come into contact. The greater wax moth is exceptional for its ability to decompose beeswax. Therefore, it reduces also pathogen loads on old beeswax in nature. The aim of this study was to determine whether the greater wax moth is able to disrupt or destroy the very resistant spores of P. larvae in its digestive tract. In the laboratory experiment, the larvae of the greater wax moth were fed on wax foundation contaminated with P. larvae spores, either loosely or fixed in cages. After 2 days, their intestine was dissected and analysed by both, cultivation and molecular methods. The greatest amount of spores was found in the first parts of the intestine, fewer spores were found in the middle parts. No spores were detected in the back parts of the intestine. If the greater wax moth were able to destroy spores of the causative agent of American Foulbrood, there would be great potential for the development of a treatment that is still lacking. However, it is still not clear if the very efficient digestive tract of the greater wax moth is able to disrupt the spores or they are accumulated in the front part of the intestine.
