A new RT-PCR test has been developed to diagnose Chronic bee paralysis virus (CBPV) that is able to detect genetically variable viral isolates. In fact, up to 8.7% divergence between partial nucleotide sequences from viral isolates from French honey bees was highlighted in a preliminary variability study. The previously-described RT-PCR was unable to detect all these viral isolates and RT-PCR diagnosis needed improvement. The new RT-PCR test can detect up to 40% more CBPV isolates.
