Honey bee colonies face numerous challenges, one of which is vulnerability to infection by various
pathogens belonging to any of the following groups: fungi, bacteria, viruses, Arthropoda, or protozoa.
Infection with any of these pathogens can lead to significant losses in colony numbers and production
(Lannutti, et al., 2020).
The Honey Bee Quantitative (HB-Q) Pathogen Panel was developed by NAGC as a tool used to screen
for the health of honey bees. NAGC’s quantitative panel is specific for the following pathogens:
Acarapis woodi (Awoodi), Acute Bee Paralysis Virus (ABPV), American Foulbrood (AFB),
Ascosphaera apis (Aapis), Black Queen Cell Virus (BQCV), Chronic Bee Paralysis Virus (CBPV),
Crithidia mellificae (Cme), Deformed Wing Virus-A (DWV-A), Deformed Wing Virus-B (DWV-B),
Deformed Wing Virus-C (DWV-C), European Foulbrood (EFB), Israeli Acute Bee Paralysis Virus
(IABPV), Kashmir Bee Virus (KBV), Lake Sinai Virus 1 (LSV1), Lake Sinai Virus 2 (LSV2),
Lotmaria passim (Lpa), Nosema apis (Napis), Nosema ceranae (Nceranae), Sacbrood Virus (SBV),
Slow Bee Paralysis Virus (SBPV), Tropilaelaps spp. (Trop).
This multi-target panel has been shown to be highly specific for each target using the unique DNA
sequence from each pathogen. In addition to the cost savings, the utilization of a multiplex panel shortens
the turnaround time which, in turn, heighten the throughput capacity of the laboratory. Since NAGC is a
testing facility, we are unable to make treatment or management recommendations based on the pathogen
results. If you have specific questions regarding treatment and/or management practices, please contact
your State Apiary Inspector’s Office.

Department of Agriculture.
