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.
