Canine distemper virus (CDV), canine adenovirus type 2 (CAV-2), canine parvovirus (CPV), and canine parainfluenza virus 5 (CPIV-5) are the major viral pathogens in dogs. Despite the availability of vaccines for dogs against these 4 viral pathogens, investigations of antibodies against these pathogens have rarely been reported in South Korea. In this study, we investigated the recent incidence of viral diseases in dogs and conducted sero-surveillance for CDV, CAV-2, CPV, and CPIV-5 in Korean dogs. The most frequently diagnosed canine viral disease in Korean dog samples from 2000 to 2022 was CPV infection, which accounted for 48.7% (464/953) of the cases. A total of 400 dog serum samples collected between 2019 and 2022 were screened for the presence of virus-neutralizing antibodies against CDV, CAV-2, CPV, and CPIV-5. The overall seropositivity rates for CDV, CAV-2, CPV, and CPIV-5 were 83.8%, 77.8%, 99.3%, and 82.0%, respectively. The protection rate against CPV was the highest (98.3%) and that against CAV-2 was the lowest (44.8%) in dog sera. Male and female dogs showed no significant differences in seropositivity rates. CDV and CPIV-5 seropositivity increased with age in dogs, and the highest incidence and seropositivity rates of CPV indicated that Korean dogs have been continuously exposed to wild CPV, and that CPV is a pathogen that urgently requires attention among canine viral diseases.

This study was conducted to survey pathogens of canine coronavirus (CCV), canine distemper virus (CDV), canine influenza virus (CIV), canine parvovirus (CPV), severe fever with thrombocytopenia syndrome virus (SFTSV), Dirofilaria (D.) immitis, Giardia and antibodies against Anaplasma (A.) phagocytophilum, Borrelia (B.) burgdorferi, Brucella (B.) canis and Ehrlichia (E.) canis among stray dogs in Gyeonggi province. We collected 271 feces, 291 bloods, 311 nasal and ocular swab samples from 311 of dogs in the Gyeonggi province assistance dogs sharing center from January to December, 2019. Among canine infectious disease pathogens, Giardia was highly detected in 46/271 (17.0%) samples. Subsequently, CCV 10.3% (28/271), D. immitis 8.2% (24/291), CPV 4.1% (11/271), CDV 1.0% (3/311), A. phagocytophilum (antibody) 0.3% (1/291), E. canis (antibody) 0.3% (1/291) were detected. Based on the results, this study is expected to provide a useful reference for disease control and management of stray dogs.

Objective: Today, the public concern for 'Companion Animal" as a family member is ever increasing. Accordingly, the cases of traditional veterinary medicine treatment targeting a companion animal has been increasing, but the traditional records in literature about this have hardly ever been introduced to academic circles. Hereupon, this writing is intending to collect the prescriptions, which were once used for treating canine diseases, in order to report them to academic circles first. Method: This writing recorded the information about canine diseases and their treatment from the books related to the orthodox oriental medicine in East Asia, and analyzed their meanings. Result: Intial records about canine diseases are found in East Asian traditional medicine books including "Bonchoseubyu"(741), "Ilwhajajegaboncho"(unidentifiable period), "Jeungryuboncho"(1082), etc. The disease perceived by humans at that time was "gwa"(a boil) which is a kind of skin ailments. In addition, these medicine books show that people at that time concentrated on the value of use of a dog as meat rather than a pain of a dog's diseases. "Hwalsujaju"(1873)which was established during the Qing Dynasty leaves the most abundant data on canine diseases. This book perceived a dog as a precious existence watching over human housing and property, according to which, canine diseases and treatment methods are subdivided. The prescriptions for a dog's disease in our country are identifiable only in "Jeungbodanbangshinpyeon"(1913)과 "Bijeongmanbyeongtongchibeop"(1933). These books include the prescriptions not only for a dog's disease but also for a disease of a cow, horse, sheep, chicken, and pig, etc. which are familiar to us. Conclusion: The prescriptions used for a dog in East Asia were different from those for people. It was found that they used a medicine noticeably for external application for easy treatment, and in case of the use of an internal medicine, they adopted a method of getting dogs to take a medicine mixed with rice or porridge for dogs. Such a clue will be applied to the traditional- medicine-based treatment of a companion animal for the time to come.

Canine infectious respiratory disease (CIRD), also known as infectious tracheobronchitis or kennel cough occurs in a multiple-dog environment such as a shelter. In this study, we were collected 300 of nasal swab samples from dogs and 145 of environmental samples from a shelter to investigate respiratory pathogens of dogs in the Gwangju metropolitan city animal shelter from February to October, 2019. Bacteria cultures for isolation of Bordetella (B.) bronchiseptica and polymerase chain reaction (PCR) tests were performed for detection of eleven canine respiratory pathogens, namely Mycoplasma (M.) cynos, canine distemper virus (CDV), canine influenza virus (CIV), canine parainfluenza virus (CPIV), canine respiratory coronavirus (CRCoV), alpha-coronavirus (CCoV), canine pneumovirus (CnPnV), canine hepacivirus (CHeV), canine adenovirus type 2 (CAdV-2), canine herpesvirus-1 (CHV-1) and canine bocavirus (CBoV). Among 300 nasal swab samples, 148 samples (49.3%) were positive for at least one pathogens. CHV-1 was the most common pathogen, found in 95/300 (31.7%) samples. Subsequently, M. cynos (22.0%), B. bronchiseptica (2.3%), CPIV (2.0%), CBoV (1.7%), CCoV (0.7%) were detected. The detection rates of M. cynos and CHV-1 according to the duration of stay in the shelter were statistically significant. Among environmental samples, M. cynos, CCoV, CBoV and CHV-1 were detected in 45/145 (31.0%). These results indicated the need for disease control and prevention systems in the shelter.

Herein, we report a case of badgers showing high morbidity and mortality rate due to the mixed infection of canine distemper virus (CDV) and Streptococcus canis (S. canis) in a farm where wild animal, badger, is being reared for herbal medicine. During the period of about one month, 120 out of 320 badgers showed severe respiratory symptoms and died, and 3 bodies were submitted to the Animal and Plant Quarantine Agency for disease diagnosis. The lung with the most severe necropsy findings failed to collapse and showed dark reddening and had yellowish nodules on the cut surface. The characteristic and common histopathologic findings include multifocal necrosis with hemorrhage of the lung, severe lymphoid depletion of the spleen and intracytoplasmic or intranuclear inclusion bodies in almost all organs. Finally, CDV and S. canis were identified by immunohistochemistry and bacterial isolation, respectively. This is the first mixed infection case of CDV and S. canis in badgers being raised on the farm.

We investigated the prevalence of canine brucellosis in companion and stray dogs between March 2015 and December 2016 and determined the disease characteristics based on the geographic distribution, sex and age of the dogs in South Korea. We conducted a large-scale survey using serological and bacteriological tests. Samples were collected from 2,394 dogs (1,825 companions and 569 strays). Thirty (1.3%) samples were positive for Brucella canis antibodies including 16 (0.9%) from companion dogs and 14 (2.5%) from stray dogs. Two (1.0%) of the 196 samples cultured from the stray dogs were positive. When compared with male dogs, the female companion and stray dogs had a significantly higher prevalence of brucellosis. Moreover, the prevalence of canine brucellosis was significantly higher in stray dogs older than 6 years and the prevalence of the disease in companion dogs was highest in Incheon (2.1%) and Jeolla (2.1%) provinces. Stray dogs from the Daejeon metropolitan area had the highest prevalence of brucellosis (7.9%). National control measures for canine brucellosis have not previously been implemented. Our findings suggest that appropriate screening tests and control measures are necessary to improve the health of dogs and to protect public health in Korea, particularly with the rapid growth of the companion animal industry.

Canine respiratory coronavirus (CRCoV) is a significant pathogen that causes respiratory diseases in dogs, collectively known as a canine infectious respiratory disease. The virus is highly contagious and exhibits high seroprevalence worldwide. Currently, bovine coronavirus (BCoV) enzyme-linked immunosorbent assay (ELISA) kits are used to detect CRCoV antibodies. However, BCoV-ELISA kits cannot differentiate between infections caused by BCoV and those caused by CRCoV. In this study, we evaluated the hemagglutination inhibition (HI) test for CRCoV by comparing it with the virus neutralization (VN) test. Subsequently, we evaluated the seroprevalence of CRCoV in 383 dog serum samples collected from South Korea utilizing the HI test. The HI test for CRCoV showed a strong correlation with the VN test (R = 0.83, p < 0.001). The analysis of seroprevalence revealed that 52.2% (95% confidence interval [CI], 47.2%-57.1%) of the Korean dog serum samples were positive. The seroprevalence exhibited varied with age, with a positivity rate of 43.9% in dogs under 1 year of age and 66.7% in dogs aged 3 to 5 years (odds ratio, 2.54; 95% CI, 1.43-4.59). In conclusion, the HI test to monitor CRCoV antibody proved to be closely related to the VN test. Furthermore, over half of the dogs in Korea tested positive for CRCoV antibodies. These findings contribute to a better understanding of the sero-epidemiology of CRCoV.

Canine parvovirus (CPV) is a major diarrhea-causing agent in puppies. Since CPV type 2 (CPV-2) emerged in 1978, new antigenic variants including CPV-2a, CPV-2b, and CPV-2c have been identified in many countries. Two puppies died suddenly at a veterinary clinic in Gyeonggi province, South Korea. Two viruses were isolated in A72 cells, confirmed as CPV strains based on a CPV rapid kit and an indirect fluorescence test and designated QIACP1403 and QIACP1404. The nucleotide sequences of complete VP2 genes of QIACP1403 and QIACP1404 were determined, and the corresponding amino acid sequences were deduced. Molecular analyses revealed that the QIACP1403 and QIACP1404 isolates were type CPV-2b. Several mutated amino acids were detected on VP2 gene residues of the two isolates. Phylogenetic analyses showed that the two isolates were most closely related to strain CPV-BM11, which was isolated from Chinese dogs in 2011. Our results suggest that these isolates may be a candidate for a vaccine to prevent CPV infection in dogs after conducting passages of the isolates in an in vitro culture system.
