Abstract: 

Contagious respiratory infections are an important cause of respiratory disease in horses,resulting in impaired pulmonary function, poor performance and sometimes severe illness. Althoughbacterial infections are often suspected to be involved, viruses are frequently overlookedand are an underestimated cause of respiratory disease outbreaks in horses. In this study, nasalswabs of 103 horses with acute symptoms of respiratory disease were analyzed for the presenceof 13 different respiratory pathogens. Gamma herpesviruses were the most commonly detected,with 60% of the samples being positive, followed by streptococcus equi subsp. zooepidemicus infection(30%). Rhinovirus B, streptococcus equi subsp. equi, adenovirus 1 and EHV-4 were morerarely detected. Further research is necessary to correctly interpret the importance of gammaherpesviruses in horses, for example by screening a healthy control population. National surveillanceof respiratory viruses in horses by PCR analysis on nasal swabs might be a useful, earlywarningsystem for viral epidemics.
