Antigenic detection of bovine parainfluenzavirus- 3 in cattle with respiratory system ınfection and some risk factors

Abstract

Bovine Parainfluenzavirus-3 is one of the major viral pathogens that causes the respiratory system disease complex of cattle. In our study, it was aimed to detect the antigenicity of bovine parainfluenzavirus-3 by direct immunofluorescence method in cattle and the effect of some risk factors on the presence of Bovine Parainfluenzavirus-3 in the herd were statistically analyzed. For this purpose, nasal swab samples were collected from sixty cattle from six different ranches. On the other hand, the farms were evaluated in terms of production type, production purpose, quarantine regulations and animal welfare. In the immunofluorescent examination, Bovine Parainfluenzavirus-3 antigen was detected in seven (7/60) preparations. It was determined that Bovine Parainfluenzavirus-3 plays an etiological role in respiratory system infections of cattle. On the other hand, in our statistical evaluation, there were statistically significant results between the presence of BPIV3 infection, quarantine practices and suitable with animal welfare, but no significant results were found between the breeding type and breeding purpose. Statistical evaluations were made to reveal the relationship between general characteristics of the animals and the presence of BPIV3, and no statistically significant result could be reached. It was concluded that especially when evaluated in terms of herd health the implement of biosafety rules in enterprises where animal circulation is frequent and bringing the enterprises in accordance with animal welfare that will provide minimum zootechnical conditions are important in protection and control. Our study is the first in Turkiye in which the risk factors of Bovine Parainfluenzavirus-3 were evaluated statistically
