Abstract

The rapid diagnosis of canine distemper virus (CDV) helps to determine the treatment of dogs in veterinary clinics. We evaluated the performance of seven commercial rapid immunochromatographic test (RICT) kits for the detection of CDV. Six core dog viral pathogens (canine adenovirus type 1 and 2, canine coronavirus, canine parainfluenza virus, canine parvovirus, and rabies virus), five CDV strains (CD1901, Lederle, Rockborn, Onderstepoort, and Synder Hill), and three bacteria (Bordetella bronchiseptica, Leptospira canicola, and Staphylococus aureus) were used to determine the cross-reactivity and detection limits of the kits. The seven commercial RICT kits did not yield positive results with the six dog viruses or the three bacteria. All the RICT kits for CDV detected the Korean CDV isolate. The detection limits of the RICT kits for the Korean CDV isolate, CD1901, belonging to Asia 1 genotype ranged from 103.0 to 104.0 TCID50/mL. There was an average difference of 1.1 in scores judged by eye between four CDV vaccine strains and CD1901 strain. Therefore, the RICT kits enable the detection of CDV vaccine strains, but need to be improved to detect CDV circulating in dog populations in Korea.
