  • This study was attempted to survey on the prevalence of canine heartworm infection (Dirofilaria immitis) in the Incheon area in 2006. This study showed comparative infection rates of canine heartworm in conjunction with different geographic locations and rearing environments (i.e., indoor, outdoor or free roaming). In total, 24 dogs (6.0%) were D. immitis positive among a total of 400 tested dogs. The geographic distribution of detection rates was Nam-gu (2 dogs, 6.7%), Yeonsu-gu (1 dog, 3.0%), Namdonggu (5 dogs, 8.0%), Pupyoung-gu (4 dogs, 6.7%), Kanghwa-gun (8 dogs, 13.0%), and Onjin-gun (4 dogs, 11.1%). In addition, 4 dogs (2.0%) or 20 dogs (10.0%) were positive for D. immitis among 202 indoor dogs or 198 outdoor dogs including free roaming dogs, respectively, while 13 dogs (11.7%) were positive for D. immitis among 111 outdoor dogs excluding free roaming dogs. In the case of 87 free roaming dogs, 7 dogs (8.1%) among them were positive for D. immitis.

  • The origin of Jindo dogs has been controversial. It has been informed by words of mouth that they are the offsprings of either the digs of Sung dynasty (960~1279 A.D.) in China or the Mongolian dogs. Some breeds of dogs in Japan now have almost same appearance as Jindo dogs. The authors reviewed the history of Japan and found that Korean hunting dogs were sent to Japan in early 5th century, which was before Sung dynasty of China. Dr. Jae-Keun Ryu of National Institute of Environmental Research has done some work on serums of dogs of both Korea and Japan; the results of his serological and molecular biological studies indicated that Korean dogs were sent to Japan 1,300~2,500 years ago. Jindo dogs appear to be the descendants of the dogs of the Stone Age. They have adapted themselves to the unfavorable environment of Jindo island so that they can maintain pure line-age and wild nature until today. It was concluded that they are Korean native dogs, not the offsprings of the dogs of Sung dynasty or the Mongolian dogs.

  • 22 dogs (31 eyes) that had treated with trimethoprim-sulfamethoxazole for tear staining syndrome at Snoopy Pet Clinic from October 2000 to September 2002 were reviewed. Of the 22 dogs, 12 were female and 10 male. Their mean (${\pm}$ SD) age was 3.5 (${\pm}\;1.3$) years. The breeds of the dogs consisted of Maltese (8 dogs), Shih tzu (6 dogs), Poodle (5 dogs), Yorkshire terrier (2 dogs), and Mixed (1 dog). The dogs received 30 mg/kg trimethoprim-sulfamethoxazole perorally twice daily for two to six weeks. 26 (19 dogs) of the 31 eyes (22 dogs) recovered completely and did not show relapse at $26{\sim}30$ weeks after treatment. Any complications did not observed. Five eyes of three dogs were not cured. Two eyes (one dogs) of them had not response to medicament and three eyes (two dogs) recurrence but the clinical signs decreased. It was considered that the trimethoprim-sulfamethoxazole was effective for the treatment in dogs with tear staining syndrome.

  • Gastro-intestinal mortility and transit time of barium sulfate after electroacupuncture were investigated in normal dogs and administration of xylatine in dogs. Electroacupuncture was performed with a current of 1.5 volt and 20 Hz at the acupoints of Tsu San Li(right(+) left(-) in dogs for 30 minutes. The results were as follows: 1. After electroacupuncture stimnlation in normal dogs, rates of stomach contractions was not changed, but amplitudes of stomach motility was markadly increased. The electroacupuncture stimulation tasted about 60 minutes after the end of electroacupuncture. 2. The stomach contractions was markedly increased, while the amplitudes of stomach motility was sligltly decreased by the administration of xylazine in dogs. 3. The rates of stomach contractions and amplitudes of motility were markedly increased after administration of xylazine in the electroacupuncture stimulated dogs. 4. Gastric emptying time o barium sulfate after electroacupuncture stimulation in dogs was highly significantly decreased compared with that of normal dogs(p < 0.01). 5. Small bowel transit time of barium sulfate after electroacupuncture stimulation in dogs was highly significantly decreased compared with that of normal dogs (p < 0.01). 6. Gastroduodenal transit time of barium sulfate after administration of xylazine following electroacupuncture stimulation dogs was blighty significantly decreased compared to that of dogs dosed with xylazine (p< 0.01). 7. Small bowel transit time of barium sulfate after administration of xylazine following electroacupuncture stimulation dogs markedly decreased compared to that of dogs dosed with xylazine (p < 0.05).

  • The purpose of this study is to identify clinical features of sound (non-lame) dogs with medial patellar luxation (MPL). Medical records of 72 dogs diagnosed with MPL were retrospectively reviewed. There were no significances in breed, sex, body weight, body condition score (BCS), osteoarthritis (OA) score, inclination of the femoral head angle (IFA), and mechanical medial proximal tibial angle (mMPTA) between sound and lame dogs, respectively. The mean age of sound dogs was significantly higher than that of lame dogs (P < 0.05), especially in MPL grade 3. The frequency of sound dogs with MPL grade 1 and 2 was 2.3 times higher than that of sound dogs with MPL grade 3 and 4 (P < 0.05). The anatomical lateral distal femoral angle (aLDFA) of sound dogs was significantly lower than that of lame dogs (P < 0.05). However, there were no statistical differences in aLDFA between sound and lame dogs in MPL grade 1, 2, and 4, except for MPL grade 3. This study suggests that in case of MPL grade 1 and 2, frequency of sound dogs is significantly high, and also that in MPL grade 3, if mean ± (standard deviation) age of the dogs is 7.4 ± 3.6 years old and the aLDFA is 105.6 ± 4.1 degrees, they are very highly possible to be sound dogs.

  • In order to detection of the Intestinal parasites, 503 fecal samples were taken from mongorel-and pad-dogs in Chonbuk province. The prevalence and identification of intestinal parasites were determined by the fecal examinations using the floatation and /or sedimentation methods and microscopical examination, respectively. The results were obtained as follows 1. Fifty-nine percent (297 dogs) from 503 fecal samples were detected eggs. In seasonal detection rate of eggs, Summer was 30.3%, Autumn 26.4%, Winter 22.3% and Spring 21.0%, in order, 2. A total of 20 kinds of eggs were isolated from feces, and it was identified 75.7% as Nematoda(320 dogs), 5.6% as Cestoda(24 dogs) and 1.4% as Trematoda(6 dogs), and 17.2% as Protozoa(73 dogs). The isolates were identified as Ancylostoma caninum (30.4%, 153 dogs), Isospora spp. (14.3%, 72 dogs), Toxocara canis(11.1%, 56 dogs), Toxascaris leonina(5.8%, 29 dogs) , Uncineria stenocephala or Physaloptera spp. (5.4%, 27 dogs), Trichuris vulpis(2.4%, 12 dogs) and the others, single or in combination. 3. In mixed infection such as single, double, triple and quadraple was 63.6%, 31.7%, 3.4% and 1.3%, respectively.

  • Mitochondrial DNA(mt DNA) of Mammalian is the circular one which the 16.5K base pairs and show the maternal inheritance. Evolutional speed of nucleotide sequence is very fast. So that polymorphic analysis of mt DNA provide the useful informations to investigate the genetic relations of interspecies. Authors trials were focussed to compare with the polymorphic differences of mitochondrial DNA between Jindo and Japanese mongrel dogs. DNA was extracted from bloods of 21 head of Jindo dogs and 20 head of Japanese dogs and isolated using 10 kinds of restriction endonucleases(Apa I, BamH I, Bgl II, EcoR I, EcoR V, Hinc II. Hind III, Pst I, Sty I, Xba I) and then separated by the agarose gel electrophoresis. After sourthern blotting hybridization was completed using the mtDNA of Japanese mongrel dogs as a probe. Autoradiography was used to compare the polymorphism of mtDNA both dogs. The results obtained were as follows; 1. mt DNA of Jindo dog showed polymorphism resulting cleavage with four kinds of restriction endonuclease, Apa I, EcoR V, Hinc II, Sty I. While in the Japanese mongrel dogs observed the polymorphism in the five kinds of restriction endonuclease supplemented with EcoR I. 2. Compared with both dogs the frequency differences of DNA polymorphism were recognized in the specific restriction endonuclease Apa I. Consequently in the restriction endonuclease Apa I both dogs classified with three types as A, B, C however in the Jindo dogs frequency of C type was 71.5 percent but in Japanese mongrel dogs observed 45 percent in the A type. 3. DNA polymorphism obtained from the use of five kinds of restriction endonuclease were classified with seven types. In Jindo dogs frequency was highest in the type 6 as 71.4 percent but in the Japanese mongrel dogs showed 35 percent in the type 5. 4. Genetic distances calculated by NEI method showed 0.0089 in Jindo dogs and was 0.0094 in the Japanese mongrel dogs.

  • A bacteriological and serological investigation was conducted in a commercial breeding kennel in Taegu city in which canine abortion caused by Brucella canis occurred, and the family dogs in this area were also surveyed for Br canis infection during a period from March 1999 to May 2000. Of 195 dogs in the breeding kennel, 50(25.6%) were found to be bacteremic and 82(42.1%) were shown to be positive for canine brucellosis by both bacteriological and serological test. Of 357 family dogs examined, 17(4.8%) had an agglutinin titer of 1 : 160 or higher. Of these 17 dogs, 5(2.8%) were from indoor dogs and 12(6.7%) were from outdoor dogs. Only 2 mongrel dogs(1 female and 1 male) of 17 serologically positive dogs showed an agglutinin titer of 1 : 2560 or higher and Br canis was isolated from their blood.
