Abstract

Na zdravlje medonosnih pčela negativno utječu brojni biotički i abiotički čimbenici, a pritom se ističu pesticidi, klimatske promjene, gubitak staništa i medonosnih paša te patogeni mikroorganizmi. U liječenju bolesti medonosnih pčela nije dopuštena primjena antibiotika, a suzbijanje se bolesti uglavnom zasniva na jačanju otpornosti pčelinjih zajednica tehnološkim i biotehničkim metodama, sukladno smjernicama dobre pčelarske prakse. Mikrobiom medonosnih pčela ima važnu ulogu u njihovom preživljavanju i otpornosti na bolesti, a uloga korisnih mikroorganizama u očuvanju zdravlja pčela očituje se primarno u inhibiciji rasta patogenih bakterija i gljivica. Mikrobiom pčela stimulira imunosni sustav, sudjeluje u razgradnji proteina i sekundarnih biljnih metabolita te sintetizira enzime kao što su glikozidaze i proteaze. Ovi enzimi sudjeluju u sintezi vitamina potrebnih pčeli i metaboliziraju neprobavljive polisaharide. Također, mikrobiom ima protuoksidativno djelovanje te sposobnost uklanjanja teških metala. Brojne znanstvene spoznaje o sastavu, funkcijama mikrobioma i povezanosti između uravnotežene crijevne mikrobiote i zdravlja pčela, potaknuli su brojna istraživanja o njihovoj upotrebi u pčelarstvu.

Abstract (english)

The health of the honey bees is negatively affected by numerous biotic and abiotic factors, including pesticides, climate change, loss of habitat and honey bee forage, and pathogenic microorganisms. In the treatment of honey bee diseases, the use of antibiotics is not allowed, and disease control is mainly based on strengthening the resistance of honey bee colonies using technological and biotechnical methods in accordance with the guidelines of good beekeeping practice. The honey bee microbiome plays an important role in their survival and resistance to diseases, and the role of beneficial microorganisms in preserving the health of bees is manifested primarily in the inhibition of the growth of pathogenic bacteria and fungi. The bee microbiome stimulates the immune system, participates in the breakdown of proteins and secondary plant metabolites, and synthesizes enzymes, such as glycosidases and proteases. These enzymes participate in the synthesis of vitamins needed by bees and metabolize indigestible polysaccharides. Also, it has an antioxidative effect and the ability to remove heavy metals. Increasing scientific knowledge about the composition, functions of the microbiome and the connection between a balanced intestinal microbiota and bee health have stimulated numerous studies on their use in beekeeping.
