“…In contrast to this, studies conducted in mainland European countries observed a greater level of genetic diversity with their cattle populations (Jackova et al 2008;Arias et al 2003;Hornberg et al 2009;Tajima et al 2001). A possible explanation for this lower level of genetic diversity within Ireland and the UK is their geographical location (Wenzel and Nusbaum 2007).…”

“…However this was not supported when the 5'UTR sequences were examined. BVDV-1a, 1f and 1g were also identified among these isolates which also included two isolates from the BVDV-2 genotype, 1 classified as BVDV-2a and 1 as BVDV-2c (Tajima et al 2001). …”

“…Two subgenotypes of BVDV-2 (BVDV type 2a and BVDV type 2b) have also been demonstrated in a number of studies (Fulton et al 2005;Flores et al 2002). A third subtype was tentatively suggested in 2001 (Tajima et al 2001) prior to a German outbreak of BVDV in 2012…”

“…In 2013 a BVDV-1q subgroup was isolated from a Bactrian camel in China (Gao et al 2013). There is less diversity between BVDV-2 isolates, with two subtypes, 2a and 2b, identified (Fulton et al 2005;Flores et al 2002), although, a third subtype, 2c has been proposed (Tajima et al 2001). This subtype was found to be the cause of a severely virulent BVD outbreak in Germany during 2012 and 2013 (Doll and Holsteg 2013).…”

The genotype and subgenotype was established for 325 field viruses and one commercial vaccine viral strain based on the analysis of at least one genomic region. BVDV-1a was the prominent subgenotype (n=317) with BVDV-1b (n=6), BVDV-1d (n=1) and BVDV-1e (n=1) also observed. A number of nucleotide sequence alignments and phylogenetic trees were constructed to represent the relationship between Irish field viruses and reference strains representative of all known BVDV genotypes and subgenotypes. Evidence of both herd specific clustering and circulation of multiple strains within herds was observed; however no evidence of county specific clustering was observed. A number of completely conserved nucleotide regions were observed and the 5'UTR was found to be more conserved than the N pro fragment analysed. The results of this study provide a detailed and comprehensive insight into the genetic diversity of BVDV in circulation within Irish cattle herds and will act as a baseline reference for future BVDV genotyping studies.
