Molecular Detection and Phylogenetic Characteristics of Herpesviruses in Rectal Swab Samples from Rodents and Shrews in Southern China.

Herpesviruses (HVs) can cause asymptomatic, benign, or fatal infections in a variety of animal species. However, the prevalence and phylogenetic characteristics of HVs in rodents and shrews in China are poorly understood. We thus performed a molecular detection and phylogenetic analysis of rat and shrew HVs in southern China between 2012 and 2014. Seventeen (6.7%) of 255 rectal swab specimens from rats and six (6.7%) of 90 rectal swab specimens from shrews tested positive for HVs. Phylogenetic analysis revealed that rodent and shrew HVs detected in this study were species specific, clustering in the Betaherpesvirinae and Gammaherpesvirinae clade. Novel Macavirus was detected in Rattus norvegicus (RN/13YX52/24 and RN/14HC50) and gammaherpesviruses in Suncus murinus (SM/14BY7/16/20/97/99/106).These findings have contributed to our understanding of the taxonomy, phylogeny, and biology of HVs.
