        American foulbrood (AFB) is caused by the bacterium Paenibacillus larvae, which is highly contagious and often lethal to honeybee broods. To control AFB, rapid diagnostic tools including those based on immunological methods are required. We produced several specific mouse monoclonal antibodies (MAbs) against P. larvae. Interestingly, a few of the MAbs were revealed to be an IgM-type antibody. To ascertain the effects of adjuvants on immunoglobulin isotype switching, BALB/c mice were immunized with various adjuvants, i.e., Freund's adjuvant (FA), Alum adjuvant, and AddaVax™ followed by the generation of hybridoma that secreted monoclonal antibodies to P. larvae. In the case of AddaVax™, all screened hybridoma clones secreted IgG-type MAbs, whereas hybridomas generated by Alum and FA secreted 91.25% (7/80) and 66.67% (11/33) respectively, IgG-type MAbs. Although the mechanism of incomplete immunoglobulin isotype switching associated with the P. larvae antigen needs further study, our results indicate that the applied adjuvants can have a significant effect on immunoglobulin isotype switching results.
