Comparison of selected canine vector-borne diseases between urban animal shelter and rural hunting dogs in Korea
A serological survey for Dirofilaria immitis, Anaplasma phagocytophilum, Ehrlichia canis, and Borrelia burgdorferi infections in rural hunting and urban shelter dogs mainly from southwestern regions of the Republic of Korea (South Korea) was conducted. From a total of 229 wild boar or pheasant hunting dogs, the number of serologically positive dogs for any of the four pathogens was 93 (40.6%). The highest prevalence observed was D. immitis (22.3%), followed by A. phagocytophilum (18.8%), E. canis (6.1%) and the lowest prevalence was B. burgdorferi (2.2%). In contrast, stray dogs found within the city limits of Gwangju showed seropositivity only to D. immitis (14.6%), and none of the 692 dogs responded positive for A. phagocytophilum, E. canis or B. burgdorferi antibodies. This study indicates that the risk of exposure to vector-borne diseases in rural hunting dogs can be quite high in Korea, while the urban environment may not be suitable for tick infestation on dogs, as evidenced by the low infection status of tick-borne pathogens in stray dogs
Vector-borne and other pathogens of potential relevance disseminated by relocated cats
© 2022. The Author(s).Large populations of unowned cats constitute an animal welfare, ecological, societal and public health issue worldwide. Their relocation and homing are currently carried out in many parts of the world with the intention of relieving suffering and social problems, while contributing to ethical and humane population control in these cat populations. An understanding of an individual cat's lifestyle and disease status by veterinary team professionals and those working with cat charities can help to prevent severe cat stress and the spread of feline pathogens, especially vector-borne pathogens, which can be overlooked in cats. In this article, we discuss the issue of relocation and homing of unowned cats from a global perspective. We also review zoonotic and non-zoonotic infectious agents of cats and give a list of practical recommendations for veterinary team professionals dealing with homing cats. Finally, we present a consensus statement consolidated at the 15th Symposium of the Companion Vector-Borne Diseases (CVBD) World Forum in 2020, ultimately to help veterinary team professionals understand the problem and the role they have in helping to prevent and manage vector-borne and other pathogens in relocated cats.publishersversionpublishe
recommendations from the CVBD World Forum
The human-animal bond has been a fundamental feature of mankind's history for
millennia. The first, and strongest of these, man's relationship with the dog,
is believed to pre-date even agriculture, going back as far as 30,000 years.
It remains at least as powerful today. Fed by the changing nature of the
interactions between people and their dogs worldwide and the increasing
tendency towards close domesticity, the health of dogs has never played a more
important role in family life. Thanks to developments in scientific
understanding and diagnostic techniques, as well as changing priorities of pet
owners, veterinarians are now able, and indeed expected, to play a fundamental
role in the prevention and treatment of canine disease, including canine
vector-borne diseases (CVBDs).The CVBDs represent a varied and complex group
of diseases, including anaplasmosis, babesiosis, bartonellosis, borreliosis,
dirofilariosis, ehrlichiosis, leishmaniosis, rickettsiosis and thelaziosis,
with new syndromes being uncovered every year. Many of these diseases can
cause serious, even life-threatening clinical conditions in dogs, with a
number having zoonotic potential, affecting the human population.Today, CVBDs
pose a growing global threat as they continue their spread far from their
traditional geographical and temporal restraints as a result of changes in
both climatic conditions and pet dog travel patterns, exposing new populations
to previously unknown infectious agents and posing unprecedented challenges to
veterinarians.In response to this growing threat, the CVBD World Forum, a
multidisciplinary group of experts in CVBDs from around the world which meets
on an annual basis, gathered in Nice (France) in 2011 to share the latest
research on CVBDs and discuss the best approaches to managing these diseases
around the world.As a result of these discussions, we, the members of the CVBD
Forum have developed the following recommendations to veterinarians for the
management of CVBDs

Molecular Identification of Borrelia spp. from Ticks in Pastures Nearby Livestock Farms in Korea
Ticks are vectors that spread pathogenic bacteria, viruses, and protozoa. As the number of ticks increases due to climate change, the importance of the study of tick-borne pathogens has also increased. This study was conducted to investigate the distribution of the major tick species causing Lyme borreliosis and regional differences in the prevalence of Borrelia spp. by tick species. Borrelia infection was confirmed not only in Ixodes ticks, which are the major vectors of Borrelia spp., but also in Haemaphysalis and Amblyomma ticks. PCR targeting the 5S-23S rRNA intergenic spacer region (rrf-rrl) was performed to confirm Borrelia positivity. A total of 6102 ticks (736 pools) were tested, and the proportion was Haemaphysalis longicornis nymphs and adults at 69.2%, Haemaphysalis flava nymphs and adults at 13.9%, Haemaphysalis spp. larva at 14.3%, Ixodes nipponensis at 0.8%, and Amblyomma testudinarium at 1.9%. Ixodes nipponensis showed the highest minimum infection rate (MIR: 34.00; 17 pools/50 ticks) for Borrelia spp., followed by A. testudinarium (MIR: 0.88), and H. longicornis (MIR: 0.05). In particular, to our knowledge Borrelia infection was first confirmed in A. testudinarium in Korea. As a result of phylogenetic analysis, all sequences were grouped with Borreliaafzelii isolates and showed a close relationship with high identity. Considering that B. afzelii causes infectious zoonotic diseases, continuous monitoring and attention are needed, although it has a low prevalence in this study
Ctenocephalides canis is the dominant flea species of dogs in the Republic of Korea
Abstract Background The status of flea infestation in dogs is an important public health concern because of their cosmopolitan distribution worldwide and the flea-borne disease transmission. In the present study, we investigated the flea infestation among 116 outdoor dogs (57 females and 59 males) in 8 rural areas of Jeonnam Province, Republic of Korea. Results Thirty-three dogs (28.4%) were infested with fleas, and all dogs were infested with Ctenocephalides canis. One dog from Hampyeong was co-infested with Ctenocephalides felis orientis, but no dogs were infested with Ctenocephalides felis felis. The reasons behind this almost exclusive distribution of flea species in dogs from Korea are currently unknown and will require further epidemiological and biological investigations. However, since all dogs investigated in the study were raised in an outdoor environment, the development of flea eggs, larvae and pupae in climatic conditions in Korea might have negatively affected the survival of other flea species. Due to the shoes-off culture and floor-heating system of Korean houses, indoor dogs are rarely infested with fleas in Korea. Conclusion To our knowledge, this is the first report on the distribution survey of flea species infesting dogs in Korea and the first report of C. orientis infesting a dog in Korea
Parasites and vector‑borne diseases disseminated by rehomed dogs
The Companion Vector-Borne Diseases (CVBD) World Forum is a working group of leading international experts who
meet annually to evaluate current scientific findings and future trends concerning the distribution, pathogenesis, clinical
presentation, diagnosis and prevention of vector-borne infections of dogs and cats. At the 14th Symposium of the
CVBD World Forum in Trieste, Italy (March 25–28, 2019), we identified the need to (i) bring attention to the potential
spread of parasites and vectors with relocated dogs, and (ii) provide advice to the veterinary profession regarding the
importance of surveillance and treatment for parasites and vector-borne infections when rehoming dogs. This letter
shares a consensus statement from the CVBD World Forum as well as a summary of the problem faced, including the
role of veterinary professionals in parasite surveillance, causal issues, and the importance of interdisciplinary cooperation
in addressing the problem. To limit opportunities for dissemination of parasites and vectors, whenever possible,
underlying problems creating the need for dog rehoming should be addressed. However, when it is necessary to
rehome dogs, this should ideally take place in the country and national region of origin. When geographically distant
relocation occurs, veterinary professionals have a vital role to play in public education, vigilance for detection of exotic
vectors and infections, and alerting the medical community to the risk(s) for pathogen spread. With appropriate
veterinary intervention, dog welfare needs can be met without inadvertently allowing global spread of parasites and
their vectors.A research fellowship from CNPq (Bolsa de Produtividade), a project funded by Bayer Animal Health (TransMIT; Z 2079), which is now part of Elanco, at TransMIT GmbH, Germany and the Fundação para a Ciência e a Tecnologia/ Ministério da Ciência, Tecnologia e Ensino Superior .http://www.parasitesandvectors.comam2021Veterinary Tropical Disease
