However, this parasite was recently detected in honey bee colonies in Spain, raising the question as to whether bees can act as true hosts for this species. To address this issue, worker bees were experimentally infected with choanomastigotes from the early stationary growth phase and after 12 days, their hindgut was extracted for analysis by light microscopy and TEM. Although no cellular lesions were observed in the honey bee’s tissue, trypanosomatids had differentiated and adopted a haptomonad morphology, transforming their flagella into an attachment pad. This structure allows the protozoa to remain attached to the gut walls via hemidesmosomes-such as junctions. The impact of this species on honey bee health, as well as the pathogenic mechanisms involved, remains unknown. Nevertheless, these results suggest that insect trypanosomatids may have a broader range of hosts than initially thought.}, organization = {Instituto de Investigacion Agropecuaria (INIA) ERTA2014-00003}, organization = {Spanish Program for Knowledge Generation and Scientific and Technological Strengthening of the R + D + I}, organization = {System, Generacion del Conocimiento PGC2018-098929-A-100}, organization = {Eva Crane Trust ECTA_20210308}, publisher = {MDPI}, keywords = {Trypanosomatid}, keywords = {Honey bee}, keywords = {Experimental infection}, keywords = {Hindgut}, keywords = {Microscopy}, title = {The Haptomonad Stage of Crithidia acanthocephali in Apis mellifera Hindgut}, doi = {10.3390/vetsci9060298}, author = {Buendía Abad, María and Pablos Torró, Luis Miguel de}, }
