Sequence variability in clinical and laboratory isolates of herpes simplex virus 1 reveals new mutations.

ABSTRACT: Herpes simplex virus 1 (HSV-1) is a well-adapted human pathogen that can invade the peripheral nervous system and persist there as a lifelong latent infection. Despite their ubiquity, only one natural isolate of HSV-1 (strain 17) has been sequenced. Using Illumina high-throughput sequencing of viral DNA, we obtained the genome sequences of both a laboratory strain (F) and a low-passage clinical isolate (H129). These data demonstrated the extent of interstrain variation across the entire genome of HSV-1 in both coding and noncoding regions. We found many amino acid differences distributed across the proteome of the new strain F sequence and the previously known strain 17, demonstrating the spectrum of variability among wild-type HSV-1 proteins. The clinical isolate, strain H129, displays a
