    Prevalence of rotavirus infections in calves with diarrhea hi Konya region
    (2010) Duman R.; Aycan A.E.
    In this study, it was aimed to investigate frequency of rotavirus infections in calves in Konya region by feces and blood sampling 106 diarrheic calves of 0-6 months old. Feces samples were examine for rotavirus antigen and blood samples were tested for specific antibodies by Enzyme Linked Immunosorbent Assay (ELISA) and whether how common rotavirus infections. Of the 106 feces samples examined by ELISA 9 samples (8.50%) were identified as positive and blood samples checked by ELISA revealed 90 samples (84.90%) developed antibodies to rotavirus. The proportion of positivity in feces and blood samples suggested that rotavirus infections are common in the region. © Medwell Journals, 2010.

    A serological survey of bovine herpesvirus-1 infection in beef herds in Turkey
    (2007) Duman R.; Yavru S.; Bulut O.; Kale M.
    3001 beef serum samples collected from 25 herds selected from central and southern regions of Turkey for the presence of BHV-1 infections by serum neutralization test. The results revealed that 78.26% of the herds from central Turkey and all of the herds from southern Turkey had seropositive animals at titres of 1:4 and above. The prevalence of BHV1 infection was found as 35.08% in central Turkey and 38.75% in southern Turkey. In conclusion, this was a decrease in prevalence of BHV-1 infection in central and southern Turkey in beef population.

    Seroprevalence of viral upper respiratory infections in dairy cattle
    (KAFKAS UNIVERSITY, 2009) Duman R.; Yavru S.; Kale M.; Avci O.
    In this research, dairy cattle, located in Konya in Central Anatolian Region and its surrounding and had respiratory system symptoms, were investigated for the seroprevalence Infectious Bovine Rhinotracheitis (IBR), Bovine Viral Diarrhea Virus (BVDV), Bovine Respiratory Syncytial Virus (BRSV), Parainfluenza Virus type 3 (PI-3) and Bovine Adenovirus type 3 (BAV-3). For that purpose, 5800 animals, one year old and over, and bred in the private farms, were investigated and the blood samples were collected from 278 animals with respiratory system disease symptoms and high body temperatures. These samples were tested for presence of antibodies against IBR, BVDV, BRSV, PI-3 virus and BAV-3 by ELISA that was bought commercially. The seroprevalences which were determined for 5 viruses in cattle -(IBR, BVDV, BRSV, PI-3 virus and BAV-3)- were 35.25%, 96.04%, 94.40%, 92.80% and 85.97%, respectively. On the other hand, 0.35% (1 animal) of the dairy cattle sampled did not have any antibodies against the viruses. The existence of antibodies against the viruses were as such; 1.43% of cattle (4 animals) had antibodies against only one virus, 2.87% of cattle (8 animals) had antibodies against two, 14.02% of cattle (39 animals) had antibodies against three, 49.64% of cattle (138 animals) had antibodies against four and 31.65% of cattle (88 animals) had antibodies against five viruses. It was determined that IBR, BVDV, BRSV, PI-3 and BAV-3 infections were widespread and seroprevalences were high.
