Abstract
Većina patogena napada probavni sustav kroz gutanje hrane. Ti patogeni zaraze epitelne stanice srednjeg crijeva, koje se stalno obnavljaju i zaštićene su membranama i filterima koji veţu patogene za tkivo crijeva. Paraziti koji inficiraju tkivo crijeva kao Nosema apis i Nosema cerana mogu stvoriti promjene na epitelnom tkivu koje omogućuju Virusu crnih matičnjaka prolaz u hemolimfu, te da zaraze ostale stanice u tijelu. U suprotnosti, vanjski parazit Varroa destructor se hrani direktno iz pčelinje hemolimfe stvarajući rupu u egzoskeletu kroz koju virus moţe ući. Većina virusnih infekcija rijetko izaziva infekciju kada se gutaju, ali samo je nekoliko virusnih čestica potrebno za izazivanje infekcije kada se ubrizgava direktno u hemolimfu. Puno virusa se moţe prenositi Varroa grinjama, kao Virus deformiranih krila i Akutna pčelinja paraliza. Ostali virusi, kao Mješinasto leglo, su primijećeni u Varroa grinjama, ali se nije primijetio prijenos virusa. Neki virusi, kao Virus deformiranih krila, se mnoţe u Varroa grinjama, iako u većini slučajeva ne znamo točnu vezu izmeĎu grinja i pčela. Nemamo dovoljno detalja o prisutnosti, ulozi i vrstama prijenosa tih virusa domaćih pčela, te ostalih mogućih vrsta prijenosa koje nemaju veze s Varrom, što nam komplicira prijedloge za kontrolu. Istraţivanja nam pokazuju da virusi utječu na zdravlje medonosnih pčela te jamči pozornost kako pčelara tako i istraţivača

Parallel abstract (English)
Most pathogens invade the digestive system through oral ingestion of inoculated food. These pathogens infect the mid gut epithelial cells, which are constantly being replaced and are protected by membranes and filters which confine the pathogen to gut tissues. Parasites that infect gut tissue like Nosema apis and Nosema cerana can create lesions in the epithelium that allow a virus like BQCV to pass into the hemolymph and infect other cells in the body. In contrast the external parasite Varroa destructor feeds directly on bee hemolymph providing an opening in the cuticle for viruses to enter. Most virus infections rarely cause infection when ingested orally, but only a few virus particles are necessary to cause infection when injected directly into the the hemolymph. Many viruses can be directly transmitted by Varroa mites, such sa: DWV, those in the acute bee paralysis virus complex, and slow bee paralysis virus. Other viruses, like sacbrood, have been detected in Varroa mites but Varroa has not been shown to directly transmit the virus. Some viruses, like DWV, have been shown to directly multiply in Varroa mites, however in most cases we don't know the exact relationship of Varroa mites to viruses or enough about how transmission occurs from mites to bees. Knowledge about the presence , role, and transmitting routes of these viruses in native bees, and other potential non-Varroa transmission routes is also lacking in detail, complicating recommendations for control. Research does show viruses clearly affect honey bee health and warrant attention from the beekeeper and researcher alike
