This study was conducted to investigate the prevalence of canine heartworm infections, canine brucellosis and hematologic values from 153 free roaming dogs in the area of Gwangju city from March to November 2006. Nineteen (12.4%) of 153 samples tested with modified Knott's technique showed positive reaction for microfilariae. Polymerase chain reaction using specific primers for D immitis amplified the expected product from all samples of 19 microfilaremic canine blood samples as determined by the modified Knott's test for microfilariae. The seasonal infection rates of microfilariae were higher in the spring season (10/19, 52.6%) than in the other seasons. The major hematological findings in microfilaremic dogs were mild leukocytosis and mild monocytosis. A total of 100 dogs randomly selected from 153 free roaming dogs were negative for canine brucellosis by serological test using immunochromatographic antibody test kit.

Animal shelters are potentially vulnerable to constant exposure to a variety of diseases for both animals and humans, because thousands of animals with unknown histories are being admitted to each shelter on a yearly basis in Korea. The control of disease spread, therefore, can be a major challenge to veterinarians in most shelters. This study investigated the health status of stray dogs admitted to the Gwangju Animal Shelter during the year of 2008, and analyzed types of disorders at the time of admission as well as newly acquired diseases while housed in the shelter. Canine heartworm disease was the most prevalent infection among stray dogs at the time of admission, while the respiratory disorder was the most common shelteracquired disease. The majority of dogs (93.5%) was either small or middle-sized breeds with Maltese (19.7%) and Shih Tzu (16.0%) being the most commonly found stray dogs. Out of 1,143 dogs admitted to the shelter, owners of 128 dogs (11.2%) visited the shelter and found their lost dogs, while 518 dogs (45.3%) were adopted to new families. Results of this study strongly indicate that stray dogs in Korea are exposed to a variety of diseases and the disease control by veterinarians is one of the most important aspects of the shelter management.

The purpose of this study was to conduct a survey of Dirofilaria immitis infection among stray cats in Korea using nested PCR. We included 235 stray cats (121 females and 114 males) and evaluated each for the presence of feline heartworm infection. Blood samples were collected from 135 cats in Daejeon, 50 cats in Seoul, and 50 cats from Gyeonggi-do (Province). Of the 235 DNA samples, 14 (6.0%) were positive for D. immitis. The prevalence of infection in male cats (8/114, 7.0%) tended to be higher than that in female cats (6/121, 5.0%), but the difference was not statistically significant. In each location, 8, 2, and 4 cats were positive for infection, respectively, based on DNA testing. No significant differences in the prevalence were observed among the geographic regions, although the rate of infection was higher in Gyeonggi-do (8.0%) than Daejeon (5.9%) and Seoul (4.0%). We submitted 7 of the 14 D. immitis DNA-positive samples for sequencing analysis. All samples corresponded to partial D. immitis cytochrome c oxidase subunit I gene sequences with 99% homology to the D. immitis sequence deposited in GenBank (accession no. FN391553). To the best of our knowledge, this is the first survey using nested PCR to analyze the prevalence of D. immitis in stray cats in Korea.

A one-year-old male Japanese Chin with anorexia, retching, dyspnea and continuous coughing was brought to the Veterinary Teaching Hospital, Chungbuk National University. Chest radiographs showed moderate regional alveolar pattern with mild interstitial patterns in the caudo-dorsal lung fields and the ill-defined mass in the perihilar area which is consistent with perihilar lymphadenopathy. Although the dog showed severe eosinophilia in the complete blood count, the serum profile values were within normal ranges. There was no indication of any parasite infestation in the direct and floatation examination of feces, skin scraping test and heartworm examination. There was no growth of bacteria and fungi in the selected media such as Mueller Hinton broth, Sabouraud Dextrose agar and Potato Dextorse agar, which were inoculated with tracheal fluid collected using endotracheal tube and cultured for 3 days. In the tracheal fluid smear, most prominent cells were eosinophils, which are a almost 80% of total cells and other cells such as leukocytes, neutrophils and ciliated colummar cells were also observed. Any parasite was also not detected in its smear. Prednisolone (PDS; 1 mg/kg, BID SC), aminophylline (10 mg/kg, TID IV) and nebulization with gentamicin (50 mg) plus saline (3 ml) were given for 1 week. At 3rd day of treatment, blood eosinophil value was return to normal range and pulmonary condition was also improved. The allergen test with serum performed during therapy was positive in the 19 index including milk, barley, tomato pomace, catfish, bonito, house dust and wool, and borderline in 10 index including wheat, house dust mites and house fly. The patient is responding well to PDS therapy. Based on these findings, a possible diagnosis of pulmonary infiltration with eosinophils was made in this dog.

Background: In modern society, the number of households raising companion animals increases, and the market for veterinary medicines is expanding even more. This study aims to investigate the perception of companion animal lovers' veterinary medicines, the necessity of specific guidance by pharmacists for veterinary medicines, the role of pharmacists at veterinary pharmacies, and ways to fulfill that role. Methods: This study evaluated veterinary medicines and medication guidance through Google online questionnaire targeting pet-lovers from December 20, 2021, until January 19, 2022. The questions consist of 1) characteristics of petlovers, 2) purchase history and drug recognition of veterinary drugs, 3) use of veterinary vaccines, 4) use of diagnostic kits, and 5) guidance of veterinary medicines by local pharmacists. Results: The respondents' experience purchasing veterinary drugs was as high as 94.4%. The most purchased drug was heartworm-preventing products, and vaccination was performed mainly at veterinary clinics (veterinarians). The respondents primarily purchased veterinary medicines for companion animals at veterinary hospitals and did not know the name of the drugs which they bought. In addition, respondents expected to receive specific information on veterinary medicines from pharmacists. Conclusion: As the number of veterinary pharmacies in the community will increase with the expansion of the companion animal market, pharmacists should play their role as experts in veterinary medicines through systematic and continuous professional education.

Scrub typhus and murine typhus are common endemic febrile illness in the fall in Korea. Scrub typhus is caused by Orientia tsutsugomushi, murine typhus is caused by Rickettsia typhi. Trombiculid mites are known as both the vector and the reservoir host of O tsutsugamushi, the mites which transmit O tsutsugomushi have been reported to be Leptotrombidium pallidum and L scutellare. The author carried out an epidemiological study of scrub typhus and murine typhus in Kyodong-Myeon, Kanghwa-Gun, Incheon in relation to the residents and the host rodents, such as their distribution, seroepidemiology, and population density of chigger mites. 1. Out of 900 residents, 33(3.7%) showed positive reaction to O tsutsugamushi, 24(2.7%) to R typhi. 2. In the seropositives to O tsutsugamushi or R typhi, between the sixties and the seventies of the age were dominant. 3. In the seropositives to O tsutsugamushi serotypically Gilliam was dominant. 4. Among the total 42 field rodents trapped by the sherman traps, 18 rodents were Apodemus agrarius(42.9%), 13 rodents were Crocidura lasiura(31.0%), 5 rodents were Musmusculus(11.9%), 2 rodents(4.8%) were Crocidura suaveolens, Rattus norvegicus, Tscherskia triton, respectively. 5. Out of 42 field rodents, 25 were parasitized by 4,419 chigger mites, showing 59.5% of the infestation rate and 98.8 of the chigger index. L pallidum parasitized in A agrarius, C lasiura, M musculus, R norvegicus and T triton, and L scutellare parasitized only C lasiura. 6. Antibodies in the sera of field rodents against O tsutsugamushi and R typhi were investigated by indirect immunofluorescent antibody technique. Positive rate of antibody against O tsutsugamushi were 11.9(5 of 42) and all of the positive is A agrarius. Antibody against R typhi was not detected. These results might provide the basic information for the management of scrub typhus and murine typhus in Kyodong-myeon, where the epidemiological studies on scrub typhus and murine typhus was not carried out enough.
