RESUMEN
Honey bee (Apis mellifera) health and hive transport are regulated by local apiary programs composed of apiary inspectors. Inspectors monitor and ensure the health of honey bees through field visits to apiaries where they inspect, identify, diagnose, and provide recommendations for the treatment of honey bee health issues. Laws and regulations pertaining to beekeeping and honey bee health are present in most states, territories, and provinces. Veterinarians are encouraged to establish a relationship with their local apiary inspector to further support beekeepers and the management of healthy honey bee colonies.

Currently, light microscopic examination of cell morphology cannot discriminate Crithidia mellificae and Lotmaria passim with 100% certainty. Here, a minor groove-binding (MGB) probe-based multiplex real-time PCR assay was developed for the simultaneous and quantitative detection of C. mellificae and L. passim in honey bees. A conserved Hymenoptera 18S rRNA gene was built in as an internal control that allows accurate detection of PCR inhibition and failure of DNA extraction. The newly developed assay was also applied to field samples. Of 21 honey bee colonies (446 bees) sampled from six counties in both central and eastern Massachusetts, 3 colonies (14.29%) and 8 bees (1.79%) were infected with L. passim, and 1 colony (4.76%) and 1 bee (0.22%) with C. mellificae. Our data showed a low rate of trypanosomatid infection, and L. passim was more prevalent than C. mellificae in honey bee samples in Massachusetts.
