“…An effective control program against the BVDV infection can be created in dairy cattle operations with the data obtained from epidemiological, diagnostic and virological studies (Lindberg and Alenius, 1999;Presi et al, 2011;Ridpath, 2012;Ståhl and Alenius, 2012).…”

“…Furthermore, PI animals are the single most important source of infection for other animals (Vilcek et al, 1997;Passler et al, 2007). Early detection and subsequent removal of PI animals is essential to a successful BVDV control programme (Moennig et al, 2005;Valle et al, 2005;Lindberg et al, 2006;Presi et al, 2011;Ridpath, 2012;Ståhl and Alenius, 2012). Although "an" OIE-listed disease, necessary national control programmes for BVDV does" not exist in many countries (Ackermann and Engels, 2006;Heffernan et al, 2009). ELISAs are preferred in studies of strategies for controlling BVDV infection because of their sensitivity and fast that allows the screening of many samples.…”

The purpose of this study was to detect of antibodies against Bovine Viral Diarrhea Virus (BVDV) in blood and milk serum samples. With this aim, a total of 192 blood and milk samples were collected from unvaccinated Holstein cows in Kars district of Turkey. Blood and milk serum samples were tested to determine the presence of antibodies against BVDV by commercial indirect enzyme-linked immunosorbent assay (ELISA). In this study, while 172 of blood serum (89.58%) were found to be positive for the presence of BVDV antibodies, 161 of milk serum samples (83.85%) were positive. In addition, 150 (78.12%) both blood and milk serum samples of same cattle were positive for BVDV antibodies. Only 22 (11.45%) blood serum of cattle was detected positive for BVDV, while only 11 (5.73%) milk serum was seropositive. Data obtained from the study showed the presence of BVDV infection in dairy herds in the Kars region and demonstrate that blood serum and milk serum samples might be consistent with one another in the determination of BVDV seroprevalence.

“…animals were eliminated and movement restrictions were applied. The campaign succeeded in reducing proportion of BVDV-positive newborn calves from 1.8% in 2008 to under 0.2% in 2010 (Zimmerli et al 2009, Presi et al 2011. Our study project is the first field evaluation of effectiveness of long-term vaccination program in reducing prevalence of persistent BVDV infection in cattle herds.…”

Effectiveness of long-term anti-BVDV vaccination program in reducing prevalence of persistent BVDV infection in cattle herds was evaluated in seven years observational study (2005)(2006)(2007)(2008)(2009)(2010)(2011). Among three seropositive dairy cattle herds (within herd seroprevalence 100%, confirmed by ELISA Herd Check BVDV Ab, IDEXX, Sweden) vaccination program based on inactivated vaccine (cytopathic strain 5960) was commenced in 2007 in two herds and continued till 2010. In the years 2007-2011 all calves aged 2-12 weeks in all three herds were tested yearly with RT-PCR in order to detect persistently infected individuals. For the entire study period true prevalence of BVDV persistent infection was significantly lower in vaccinated than in non-vaccinated herd. This may imply the role of long-term vaccination program in reducing prevalence of persistent BVDV infection in cattle herds.

“…(Bachofen et al 2010;Barrett et al 2011;Houe 1999;Houe 2003;Lindberg 2002;Sayers 2014). Eradication and control programmes are becoming increasingly common internationally (Stahl et al 2005;Lindberg 2002;Presi et al 2011) and will benefit from a greater understanding of BVD is an infectious disease of both domesticated and free living animals including:…”

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.
