Molecular characterization of the first G24P[14] rotavirus strain detected in humans

• First report of G24P[14] genotype in humans
• Second report of G24 genotype overall
• Four genes are similar to bovine rotavirus strains.
• Other genes resemble animal and human strains.
• This strain is likely the product of multiple reassortant events.

Here we report the genome of a novel rotavirus A (RVA) strain detected in a stool sample collected during routine surveillance by the Centers for Disease Control and Prevention's New Vaccine Surveillance Network. The strain, RVA/human-wt/USA/2012741499/2012/G24P[14], has a genomic constellation of G24-P[14]-I2-R2-C2-M2-A3-N2-T9-E2-H3. The VP2, VP3, VP7 and NSP3 genes cluster phylogenetically with bovine strains. The other genes occupy mixed clades containing animal and human strains. Strain RVA/human-wt/USA/2012741499/2012/G24P[14] most likely is the product of interspecies transmission and reassortment events. This is the second report of the G24 genotype and the first report of the G24P[14] genotype combination in humans.
