ZBITNEW A: UPPER RESPIRATORY DISEASE IN THOUROUGHBRED HORSES: STUDIES OF ITS VIRAL ETIOLOGY IN THE TORONTO AREA, 1960 TO 1963.

Abstract: From outbreaks of upper respiratory infection of horses in the Toronto area between 1960 and 1963, several viruses have been isolated. The viruses, isolated in tissue cultures or eggs, include an equine strain of Myxovirus parainfluenzae 3; two strains of equine influenza virus, A/equi-1/Prague/56, and A/equi-2/Miami/63; equine rhinopneumonitis virus, and two newly recognized viruses of the horse, equine rhinoviruses. In addition serological evidence suggested a widespread infection with these viruses in the population under study. Because of the identical clinical picture seen and the complex etiology of the disease, immunization against upper respiratory disease of the horse does not appear to be completely feasible at this time.

This research investigates the causes of upper respiratory infections in thoroughbred horses in the Toronto area from 1960 to 1963, finding several viruses behind the outbreak, and suggesting that immunization may not currently be fully achievable.

Study Overview

  • This study was conducted with the main aim of identifying the viral causes of upper respiratory infections in thoroughbred horses in the Toronto area over a three-year span from 1960 to 1963. This was done through the isolation of various viruses from the horses that suffered from such infections during the period of study.

Viral Identification

  • The researchers were able to isolate several viruses from tissue cultures or eggs of the affected horses. These inculde an equine strain of Myxovirus parainfluenzae 3, two strains of equine influenza virus, namely A/equi-1/Prague/56 and A/equi-2/Miami/63.
  • Additionally, they also identified the equine rhinopneumonitis virus, and two new viruses which had not been previously recognized, termed as equine rhinoviruses.

Serological Evidence

  • Apart from the viruses that were physically isolated, serological evidence, based on the presence of specific antibodies in the horses’ bloodstream, indicated a widespread infection with these identified viruses in the horse population studied.

Complex Etiology and Immunization Feasibility

  • Despite the identification of multiple viruses, the clinical picture presented by the horses infected was more or less the same, suggesting a complex etiology – or cause – behind the disease. This complexity makes it harder to find a one-size-fits-all solution to the problem.
  • The authors of the study also noted that due to this complex cause behind the disease, the development and implementation of an effective immunization program against this upper respiratory disease does not seem completely feasible at this time. This suggests a need for further research and development to combat this problem.
