  • Background: The feline viral rhinotracheitis, calicivirus, and panleukopenia (FVRCP) vaccine, prepared from viruses grown in the Crandell-Rees feline kidney cell line, can induce antibodies to cross-react with feline kidney tissues. Objectives: This study surveyed the prevalence of autoantibodies to feline kidney tissues and their association with the frequency of FVRCP vaccination. Methods: Serum samples and kidneys were collected from 156 live and 26 cadaveric cats. Antibodies that bind to kidney tissues and antibodies to the FVRCP antigen were determined by enzyme-linked immunosorbent assay (ELISA), and kidney-bound antibody patterns were investigated by examining immunofluorescence. Proteins recognized by antibodies were identified by Western blot analysis. Results: The prevalences of autoantibodies that bind to kidney tissues in cats were 41% and 13% by ELISA and immunofluorescence, respectively. Kidney-bound antibodies were observed at interstitial cells, apical border, and cytoplasm of proximal and distal tubules; the antibodies were bound to proteins with molecular weights of 40, 47, 38, and 20 kDa. There was no direct link between vaccination and anti-kidney antibodies, but positive antibodies to kidney tissues were significantly associated with the anti-FVRCP antibody. The odds ratio or association in finding the autoantibody in cats with the antibody to FVRCP was 2.8 times higher than that in cats without the antibody to FVRCP. Conclusions: These preliminary results demonstrate an association between anti-FVRCP and anti-cat kidney tissues. However, an increase in the risk of inducing kidney-bound antibodies by repeat vaccinations could not be shown directly. It will be interesting to expand the sample size and follow-up on whether these autoantibodies can lead to kidney function impairment.

  • In this study, we examined the developmental potential of reconstructed bovine embryos and the fate of donor mitochondria during their preimplantation development after nuclear transfer. Isolated cumulus cells were used as donor cells in nuclear transfer. Cumulus cells labelled with MitoTracker Green FM fluorochrome were injected into enucleated bovine MII oocytes and cultured in vitro. MitoTracker labelling on donor cells did not have a detrimental effect on blastocyst formation following nuclear transfer. Cleavage rate was about 69%(56/81) and blastocyst formation rate was 6.2% (5/81) at 7 days after nuclear transfer. The labelled mitochondria dispersed to the cytoplasm and became distributed among blastomeres and could be identified up to the 8- to 15-cell stages. Small patches of mitochondria were detected in some 8- to 15-cell stage embryos (5/20). However, donor mitochondria were not detected in embryos at the 16-cell stage and subsequent developmental stages. In the control group, mitochondria could be identified in arrested 1-cell embryos up to 7 days after nuclear transfer These results suggest that donor mitochondria disappear from recipient cytoplasm before 16-cell stage following nuclear transfer in reconstructed bovine embryos.

  • This study was carried out to examine the influence of minimum essential medium (MEM) vitamins supplementation to in vitro maturation medium and in vitro culture medium on the development of porcine embryos. Porcine embryo development was investigated following cultivation in both in vitro maturation and culture medium with the supplementation of MEM vitamins (0, 0.1, 0.2 and 0.4%) using immature oocytes collected from the ovary of prepubertal gilts. Embryo development was observed and the total cell number in each blastocyst generated under the culture conditions was quantified following supplementation of the medium. The embryonic development rate of the blastocyst and hatched blastocyst was higher, but not significantly so, when 0.4% MEM vitamins were supplemented to the in vitro maturation medium of the porcine oocyte. Interestingly, the total number of cells in the blastocyst was significantly higher in the in vitro maturation MEM vitamins supplemented group compared to either the untreated group or the group which had MEM vitamins supplemented to both in vitro maturation and in vitro culture medium simultaneously (p<0.05). Therefore, the supplementation of 0.4% MEM vitamins to the in vitro mature medium has a beneficial effect on the embryonic development of in vitro produced blastocysts derived from the immature porcine oocytes.

  • Background: The change in size and weight of the female reproductive organs during gestation and birth might be affect the perineal muscles and this condition in dairy cow not been reported. This study aimed to assess the ultrasonographic image of coccygeus muscle in 11 inseminated dairy cows with different gestational ages and postpartum. Methods: Gestational age was calculated based on the record of artificial insemination and confirmed by using transrectal brightness mode ultrasonography. Perineal hair between the sacrum and ischium bones was shaved along 3-5 cm before being ultrasound. The images of perineal area were obtained by transcutaneous ultrasound using a 5.0 MHz transducer. The thickness and intensity of the coccygeus muscle were measured and analyzed by gestational status and postpartum to show the differences. Results: The results showed that the thickness of coccygeus muscle increased with the increase in gestational age. Muscle intensity only increased at young gestational age. However, it decreased with the increase in gestational age (P < 0.05). Conclusions: The ultrasound image of coccygeus muscle was affected by gestational status, thus this method may be used as one of the new methods of indirect gestational detection on dairy cows.

  • Two weeks of therapy with intra-articular hyaluronic acid and oral caprofen failed to improve the clinical signs of hip osteoarthritis radiologically confirmed in a dog. Then, over the period of 30 days (7 sessions at 5-day intervals), bee- venom acupuncture (BV-AP, injection of bee venom at acupoints, also called apitoxin-aquapuncture) plus Trigger Point (TP) therapy was used. Five acupoints on the affected right limb were injected each time: GB30(as local point), plus ST35, GB33, BL40 and LIV08 (as distant points). The injection mixture (0.2 ml/point; total 1 ml/session) was saline + apitoxin + 2% lidocaine, so that the injected solution contained $100{\mu}g$ apitoxin diluted in 0.2% lidocaine-saline solution/ml. The total dose of apitoxin used was, therefore, $100{\mu}g/session$, divided over the 5 acupoints. One TP in the middle of the right quadriceps muscle was injected with 2% lidocaine (0.2 ml/point) each time. BV-AP improved the clinical signs rapidly; lameness and ataxia were disappear after 7 sessions (30 days); the right hind limb muscular atrophy was much improved and the hip radiograph was almost normal two weeks after 7 sessions (44 days). The present patient was a case with canine hip osteoarthritis which showed favorable therapeutic response by BV-AP plus TP therapy.

  • Salmonella enterica serotype Choleraesuis causes swine paratyphoid, with clinical findings of enterocolitis and septicemia. However, the clinicopathological features of S. Choleraesuis infections in pigs have not been reported in Korea. We describe the pathological findings of two weaned pigs with S. Choleraesuis infections, presenting with diarrhea, cough, and sudden death. Pathological examination indicated severe necrotic colitis in pig 1 and septicemic lesions in pig 2. Multidrug-resistant S. Choleraesuis was isolated from the pigs' lungs and intestinal contents. Further research is required for the surveillance of S. Choleraesuis infections in pigs and the virulence estimation in the S. Choleraesuis isolates.

  • To report retinal image of in a 6-year-old male castrated poodle dog with a 2-month history of nyctalopia using optical coherence tomography (OCT). Ocular reflexes were present in both eyes and slit lamp examination showed anterior subscapular cataract in the right eye. There were fundus abnormalities in both eyes similar to retinal degeneration. Scotopic electroretinograms (ERGs) revealed significantly subabnormal amplitudes and prolonged implicit time, whereas photopic ERGs were better maintained, although far from normal. OCT of affected dogs revealed generalized retinal thinning much more than a normal age-matched dog. Therefore, OCT scanning is considered to be a useful method for retinal evaluation in dogs with retinal degeneration.
