  • 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.

  • Recently cases of canine distemper have occurred in Korea despite vaccination was carried out nationwidely. This study was performed to establish rapid diagnosis of canine distemper by RT-PCR, nested PCR, and serological test. A total of 30 dogs, which were suspected canine distemper clinically, was examined. RT-PCR and nested PCR were specific for the amplification of CDV H gene and sensitive to detect 7 TCID50 of Onderstepoort strain. By RT-PCR, H gene was detected in 6(20%) of 30 peripheral bloods from dogs. And H gene was detected in 10(33.3%) of 30 samples by nested PCR. H gene was detected from 1 brain of 6 years-old Beagle dog and 1 lung of 2 months-old Shihtzu dog, in which peripheral blood H gene was not detected. Serum neutralizing antibody titer against Onderstepoort strain ranged from 4 to 1,024 in 30 patients. No correlation was observed between the results of nested PCR and titiers of neutralizing antibody.

  • An indirect immunofluorescent antibody test was applied to survey the antibody prevalence on five canine viruses including canine distempervirus(CDV), canine parvovirus(CPV), canine coronavirus(CCV), canine adenovirus type-2(CAV-2), canine parainfluenzavirus(CPIV) in dogs. The period studied was from October 1992 to June 1993. A total of 80 dog sera was collected from veterinary clinics in Kwangju and Seoul, and examined for the presence of virus antibodies. Immunofluorescent antibodies(IFA) to all viruses were present in a high percentage of 80 sera tested. Seventyfive(93.8%) showed detectable IFA against CPV, 67(83.8%) against CDV, 51(63.8%) against CCV, 42(52.5%) against CPIV and 34(42.5%) against CAV-2. These suggested that all viruses were endemic in the communities. IFA levels against each virus were also distributed fairly irregularly. IFAs for CDV and CPV were detected more frequently with a relatively high incidence in vaccinated group less than 1 years of age. IFAs for CAV-2 were detected more frequently with growing age. In the correlation of clinical signs and antibody prevalence, dogs that showed hematochezia and vomiting had high titers in the positive sera is noteworthy, particularly for CDV and CPV. The significance between dogs those who had diarrhea, dyspnea and salivation and those viruses were obscure.

  • Siewert-Kartagener's syndrome, a type of primary ciliary dyskinesia, is a complex disease comprising situs inversus, rhinosinusitis, and bronchiectasis. Situs inversus totalis is a condition in which all organs in the thoracic and abdominal cavities are reversed. Furthermore, primary ciliary dyskinesia, an autosomal genetic disease, may coexist with situs inversus totalis. Reports on Siewert-Kartagener's syndrome in veterinary medicine are limited. We report a rare case of primary ciliary dyskinesia with Siewert-Kartagener's syndrome in a dog, concurrently infected with canine distemper virus and type-2 adenovirus. This case highlights that situs inversus totalis can cause primary ciliary dyskinesia, and concurrent infections are possible.

  • This study was carried out to produce IgY against B. bronchiseptica, parvovirus and distemper virus that are major pathogens in alimentary and/or respiratory diseases of dogs. In the comparison of adjuvants, ISA70 was the best in the rapid induction and maintence of antibody titers. Agglutination antibody titers against B. bronchiseptica were 1:1,280 ~ 1:10,240 in sera and 1:160 ~ 1:1,280 in egg yolk. Hemagglutination inhibition(HI) titers against parvovirus in sera and egg yolk were 1:80 ~ 1:320 and 1:64 ~ 1:256, respectively. Virus neutralization titers against canine distemper was 1:8 ~ 1:64 in sera and egg yolk. These results suggested that egg yolk antibody titers could be variable according to a sort of adjuvant and antigens of the pathogens.

  • Recently, companion animal culture has grown rapidly and mature, raising interest in preventing and treating animal diseases. In particular, viral infection was a serious threat to companion animal health because there was no proper antiviral drugs. Synthetic antiviral drugs have limitations such as low efficiency, toxicity, and occurrence of resistant viruses. Therefore, attempts to find new anti-viral drugs from natural sources have continued. This review focused on the natural products and active substances that exhibit antiviral activity against three viruses: canine distemper virus (CDV), canine parvovirus (CPV), and feline calicivirus (FCV) that cause fatal diseases in dogs and cats. Natural plant extracts, flavonoids, polysaccharides, alkaloids and saponins showed antiviral activity with various mechanisms and differences in activity depending on the structure. Especially, quercetin and epigallocatechin-3-gallate (EGCG) showed antiviral activity through a multi-mechanism that interferes with the attachment and penetration stages of the virus and inhibits the viral polymerase within the cell. Some natural plant extracts showed a virucidal activity and showed the potential effect as a preventative agent to prevent the viral infection. This review is expected to provide research trend on the development of antiviral natural products for companion animals.

  • There were outbreaks of canine distemper in Korea from the late 1990's to the early 2000's even though modified live CDV vaccines had been used as the same way as before. The present study was undertaken to investigate the levels of neutralizing antibodies in the Korean dog population, and the factors associated with the levels, with special reference to the vaccination history of the dogs. A total of 772 serum samples were from clinically healthy dogs with over one year old throughout the Korea from January 2003 to April 2004. Details on the sex, breed, age, vaccination status and disease histories were recorded. The level of neutralizing antibodies titer was determined with a modified version of the microneutralization test. Titers over 16 were classified as protective CDV antibody titers. The overall rate of adult dogs with protective antibody titers was 96.0%. The dogs with protective antibody titers varied depending on age, sex, rearing environment and vaccination status. Because the majority of healthy adult dogs in Korea had adequate serum antibody titers against CDV and the immunity provided by the vaccinations is claimed to last for several years, annual revaccination protocol for CDV in adult dogs should be reconsidered.

  • Animals and disease frequency of the rescued dogs were investigated in Incheon Veterinary Medical Association Animal Shelter from January in 2012 to December in 2013. Three zoonoses (rabies, brucellosis, and dirofilariosis) and three infectious diseases (canine distemper, canine parvoviral enteritis, and canine influenza) were examined for stray dogs. Among 5,603 heads, 647 (11.5%) went back to their owner and 969 (17.3%) were adopted to new families. Prevalence of dirofilariosis, canine distemper and canine parvoviral enteritis were 2.2% (16/718), 6.0% (24/399) and 6.1% (24/396), respectively. Positive antibody rates against rabies, B. canis and canine influenza virus were 20.5% (41/200), 0.1% (1/718) and 2.0% (4/200), respectively. Protective antibody for canine distemper virus and canine parvovirus were shown in 47.0% (94/200). The data indicate that control measures including facility standards and disease control program are one of the important aspects of the shelter management because stray dogs are exposed to various infectious agents.

  • A methicillin-resistant Staphylococcus aureus (MRSA) isolate was recovered from a 9-month-old female Shih-Tzu dog with canine distemper virus infection. We performed in vitro antimicrobial susceptibility test to determine the most effective antimicrobial drug against the isolate and thus, to emphasize its potential clinical importance in animal practices. Isolate was confirmed MRSA by oxacillin agar screening test. The isolate was fully resistant to all $\beta$-lactam antibiotics and was susceptible to glycopeptides. Of the other antibiotics, mupirocin, TMP/SMZ (trimethoprim-sulfamethoxazole), and chloramphenicol showed inhibitory effect at the concentration of 4x MIC. The MICs ranged 0.25->$128{\mu}g/ml$, and MBCs ranged 0.5->$128{\mu}g/ml$. The combined TMP/SMZ with cefamandole or novobiocin showed synergistic effect, whereas the combination of novobiocin plus cefamandole or teicoplanin resulted in antagonistic effects. Although MRSA in animals so far has been reported in the geographically limited countries, at least theoretically, it could be occurred in the future more frequently through either human or animal origin. The use of this combination may be of value in this situation. As with all antimicrobial agents, inappropriate or unnecessarily prolonged therapy may contribute to the emergence of resistance strains and loss of efficacy.
