Seroprevalence of canine herpesvirus-1 and Brucella canis in Finnish breeding kennels with and without reproductive problems

Abstract

We compared the serological status of Brucella canis and canine herpesvirus-1 (CHV-1) in Finnish breeding kennels with and without reproductive problems. Dogs from kennels with reproductive problems had significantly higher CHV-1 titres than dogs from kennels having no reproductive problems (p < 0.001). In dogs from kennels with reproductive problems 100% (32/32) had positive titres, whereas in dogs from kennels without reproductive problems 65% (22/34) had positive titres. The median titre for dogs from kennels with reproductive problems was 1 : 160 and for dogs from kennels without reproductive problems 1 : 80. The high prevalence of positive CHV-1 titres in this study indicates that prevention of the disease is difficult and reinforces the need to minimize the reproductive problems caused by CHV-1. All 388 dogs from 94 kennels had negative B. canis titres.
