Serological detection of infection dynamics for respiratory viruses among dairy calves.

The aim of this study is to reveal infection dynamics of bovine respiratory syncytial virus (BRSV), bovine parainfluenza virus type 3 (PI-3), bovine herpesvirus 1 (BHV-1), bovine viral diarrhea virus (BVDV), bovine adenovirus type 3 (BAV-3) and bovine coronavirus (BCoV), which are important viral pathogens of respiratory disease complex in ruminants. Through such an analysis, the regression period of maternally derived antibodies and optimum vaccination time in calves can be recommended. A total of 10 farms were grouped as large (4)-, medium (2)- and small (4)- sized enterprises according to their animal population.

Tick survey and detection of Crimean-Congo hemorrhagic fever virus in tick species from a non-endemic area, South Marmara region, Turkey.

Crimean-Congo hemorrhagic fever (CCHF) is an increasing health concern in Turkey since 2002. There were also some recent human cases from the South Marmara region of Turkey; thus, a tick survey was performed, and possible vector tick species for the CCHF virus were determined in the region. A total of 740 adult ticks were collected from infested livestock from five locations: Çanakkale-Biga, Bursa-Orhaneli, Bursa-Keles, Balıkesir and Bilecik.

Serological evidence for infections with Borna disease virus in Turkey.

Distribution of Borna disease virus (BDV) infection outside endemic areas has been studied in several countries. We examined serum samples for anti-BDV antibodies in purebred racing horses and other domestic animals in Turkey. In total serum samples of 437 animals including 282 horses, 50 sheep, 25 goats, 50 cattle, and 30 cats were tested by indirect immunofluorescence assay (IFA).

Seroprevalence of canine herpesvirus-1 in Turkish dog population.

Canine herpesvirus-1 (CHV-1) is the agent of reproductive and respiratory disorders in adult dogs, and the infection generally results in haemorrhagic disease conditions and neonatal death. In this study, virus neutralisation test that used complement (VNT) as well as in-house ELISA were utilised to investigate the CHV-1 seroprevalence in the Turkish dog population. Among the 560 serum samples, 39.
