Lotmaria passim is a trypanosomatid that infects honey bees. In this study, we established an axenic culture of L. passim from Italian isolates and then used its DNA as a control in subsequent analyses that investigated environmental DNA (eDNA) to detect this trypasonosomatid. The source of eDNA was honey, which has been already demonstrated to be useful to detect honey bee parasites. DNA from a total of 164 honey samples collected in the North of Italy was amplified with three L. passim specific PCR primers and 78% of the analysed samples gave positive results. These results indicated a high prevalence rate of this trypanosomatid in the North of Italy, where it might be considered another threat to honey bee health.

Analysis of honey environmental DNA indicates that the honey bee (Apis mellifera L.) trypanosome parasite Lotmaria passim is widespread in the apiaries of the North of Italy

Abstract

Lotmaria passim is a trypanosomatid that infects honey bees. In this study, we established an axenic culture of L. passim from Italian isolates and then used its DNA as a control in subsequent analyses that investigated environmental DNA (eDNA) to detect this trypasonosomatid. The source of eDNA was honey, which has been already demonstrated to be useful to detect honey bee parasites. DNA from a total of 164 honey samples collected in the North of Italy was amplified with three L. passim specific PCR primers and 78% of the analysed samples gave positive results. These results indicated a high prevalence rate of this trypanosomatid in the North of Italy, where it might be considered another threat to honey bee health.
