Abstract
We studied the prevalence of tickborne pathogens in canine ticks, South Korea, during 2010–2015. Results revealed a high prevalence of the emerging pathogen Rickettsia raoultii. Dog ticks may be maintenance hosts for tickborne pathogens, suggesting the need to continually evaluate the potential public health threat posed by R. raoultii–infected ticks.
Highlights
We studied the prevalence of tickborne pathogens in canine ticks, South Korea, during 2010–2015
R. raoultii had not been detected in humans, animals, or vectors in South Korea until recently, but it appears to be endemic in ticks infesting dogs
Our findings are consistent with the results of a previous study from South Korea, in which H. longicornis ticks were found in 201 (48.9%), Haemaphysalis spp. ticks in 130 (31.6%), H. flava ticks in 71 (17.3%), and I. nipponensis ticks in 7 (1.7%) of 411 dogs (4)
Summary
We studied the prevalence of tickborne pathogens in canine ticks, South Korea, during 2010–2015. Our study assessed risk factors for and the prevalence and coinfectivity of several tickborne pathogens in ticks collected from dogs in South Korea. Rickettsia spp. are emerging or reemerging pathogens with public health relevance; 1 species, R. raoultii, causes human tickborne lymphadenitis in many countries in Europe (3).
