To investigate the molecular epidemiology and genetic diversity of bovine enteric caliciviruses, a total of 167 fecal samples from diarrheic calves were screened. Bovine noroviruses (BoNoVs) and neboviruses were detected in 56 (33.5%) and 37 (22.1%) fecal samples, respectively. Sequences of the RdRp and capsid gene of selected BoNoVs showed that the GIII.1 and GIII. 2 genotypes were in circulation in Turkey. Two of the BoNoV strains were identified as recombinant strains (GIII. P1/GIII.2). All examined neboviruses possessed a Nebraska-like RdRp gene. The two nebovirus strains were classified into lineage 4 based on phylogenetic analysis of VP1 amino acid sequences. One of them showed evidence of a recombination event within the S domain. This study is thus the first to reveal the presence of the BoNoV GIII. 1 genotype and recombinant strains of BoNoV and neboviruses in Turkey.
