Here we describe the first known case of HSV mistyping due to a previously undescribed HSV-1 x HSV-2 recombination event in UL27, the gene that encodes glycoprotein B. This is the first reported HSV interspecies recombination event impacting this gene, which is frequently used as a target for diagnostics and experimental therapeutics.
