Background
Emergent and re-emergent canine tick-borne infections are attracting increasing attention worldwide. The rise in pet ownership and the close relationship between dogs and their owners are the most concerning factors because dogs may act as competent reservoirs for human tick-transmitted infectious agents.
Objectives
This study contributes to the epidemiological surveillance of canine tick-transmitted infections with zoonotic risk in the Republic of Korea (ROK) by investigating the seroprevalence of the pathogens,
Anaplasma
spp.,
Borrelia burgdorferi
, and
Ehrlichia canis
.
Methods
Four hundred and thirty whole blood samples from domestic dogs were collected in seven metropolitan cities and nine provinces in the ROK and tested using SensPERT Ab test kits (VetAll Laboratories®) to detect seroreactive animals.
Results
The seroprevalence rates identified were 9.8% (42/430) for
Anaplasma
spp., 2.8% (12/430) for
B. burgdorferi
, and 1.4% (6/430) for
E. canis
. The risk factors evaluated in this study that could be associated with the development of a humoral immune response, such as sex, age, and history of tick exposure, were similar. There was only one exception for dogs seroreactive to
Anaplasma
spp., where the risk factor “tick exposure” was statistically significant (
p
= 0.047).
Conclusions
This serological survey exhibited the widespread presence of
Anaplasma
spp.,
B. burgdorferi
, and
E. canis
throughout the ROK. Hence, dogs may play a key role as the sentinel animals of multiple zoonotic infectious agents in the country.
