This study assessed the seroprevalence of Babesia gibsoni in companion dogs in Korea by enzyme linked immunosorbent assay using recombinant BgTRAP antigen. Dogs were randomly selected from those admitted for various reasons to local private veterinary hospitals and the Animal Medical Center of Chonbuk National University. With the owners' permission, extra blood was drawn from each dog for serological assays. Of the 188 selected dogs, seven (3.72%) were positive for B. gibsoni, including six of 167 (3.59%) indoor and one of 12 (8.33%) outdoor dogs. Of the seven dogs positive for B. gibsoni, four were aged > 10 years, two were < 1 year, and one was between 1 and 10 years; and two were Yorkshires and one each was Shih-tzu, Maltese, Pekinese, beagle and mixed. Concurrent diseases or chief complaints were anemia in two dogs, both of which had a history of confirmed babesiosis by polymerase chain reaction, and non-anemic diseases in five. Geographically, four dogs were from Jeonbuk/Jeonju, and one each from Seoul, Gyounggi-do, and Jeonnam/Gwangju. To our knowledge, this is the first report of companion dogs in Korea being seropositive for B. gibsoni. Serologic screening of subclinical or carrier dogs can detect this potentially dangerous disease and assess its epidemiology.

This study was conducted to determine and to standardize the time of emergence of Protaetia brevitarsis adults, through four breeding experiments, including one which selected the dominant individuals of Protaetia brevitarsis. The breeding experiments were divided into two groups with hibernating and non-hibernating Protaetia brevitarsis by placing 100, 150, 200, 250 and 300 Protaetia brevitarsis in each breeding box (50 cm × 35 cm × 15 cm) filled with 12 L of fermented sawdust. Breeding tests were with four replicates each for 3 months. The test period was classified into four stages: Exp. 1 (Sep 1, 2019 to Nov 30, 2019), Exp. 2 (Dec 1, 2019 to Feb 29, 2020), Exp. 3 (Mar 1, 2019 to May 31, 2020) and Exp. 4 (Jun 1, 2020 to Aug 31, 2020). The survey items included average dead number, average emergence number, average mortality, and average emergence rate. In Exp. 1 and 2, the changes in Protaetia brevitarsis adults were similar. In Tables 1 and 2, the allegorical changes of adult white-spotted flowers were similar. In addition, the average dead number, average emergence number, average mortality, and average emergence rate showed better results in the hibernation state than in both Exp. 1 and 2. Exp. 3 and 4 showed a pattern of change different from the results of Exp. 1 and 2 and these characteristics were superior in the hibernation states compared to the non-hibernation states. In conclusion, this result was found to be most appropriate as a standardization of the emergence time of 200 Protaetia brevitarsis treatments through four breeding experiments in the hibernating state.

As the number of households that raise dogs and cats is increasing, there is growing interest in animal health. The gut plays an important role in animal health. In particular, the microbiome in the gut is known to affect both the absorption and metabolism of nutrients and the protective functions of the host. Using probiotics on pets has beneficial effects, such as modulating the immune system, helping to reduce stress, protecting against pathogenic bacteria and developing growth performance. The goals of this review are to summarize the relationship between probiotics/the gut microbiome and animal health, to feature technology used for identifying the diversity of microbiota composition of canine and feline microbiota, and to discuss recent reports on probiotics in canines and felines and the safety issues associated with probiotics and the gut microbiome in companion animals.

A common kestrel (Falco tinnunculus) was presented with inability to stand and fly at Chungnam Wild Animal Rescue Center. The kestrel showed non-weight bearing ambulation on both legs and crepitation with no external wound. Radiographs revealed a fracture on mid-diaphysis of right tibiotarsus and a distal end fracture of left femur. Intramedullary pinning was chosen for reduction of both fractures. The right tibiotarsal fracture was corrected first, and left femur was repaired 5 days later. The kestrel was managed with a specially designed sling to prevent further iatrogenic damage for 2 weeks. Three weeks after the surgery, the kestrel was able to stand and found to perch in 4 weeks. On 5 weeks, The kestrel could fly free at outdoor aviary and was released through rehabilitation for 3 months finally.

This study was designed to evaluate to acute oral toxicity and skin irritation of Chrysanthemum dye in Sprague-Dawley (SD) rats. SD rats were orally treated with Chrysanthemum dye at a dose of 0, 1 and 2 ml/kg body weight. After oral administration, the rats were observed for 14days. In primary skin irritation test, SD rats were dermally treated with Chrysanthemum dye and observed for 3 days. To ensure the safety of Chrysanthemum dye such as the following were observed and tested. We examined the body weight, the feed intake, the clinical signs, the ophthalmological test, the histopathological test, the mortality and skin irritation. As a result, no significant differences were found in body weight, feed intake and histopathological test between control and Chrysanthemum dye treated group. In the result of skin irritation test, Chrysanthemum dye did not induce erythema and edema after topical application. Primary irritation index was "0" in the test. Therefore, it is suggested that Chrysanthemum dye has no effect on acute toxicity and side effect in SD rats and is non-irritant material based on the score "0" of primary irritation index.

Companion animals are physically, mentally, and socially beneficial to humans, giving us great comfort in living in the Corona19 (COVID-19) era. It is also an era of the Fourth Industrial Revolution, featuring the convergence of information and communication technology. Korea, which is facing a super-aged society, has the highest suicide rate among OECD countries, and companion animals that are effective in emotional stability can be the answer. This study is about companion animals that are effective in stabilizing the emotions of the elderly, one of the major problems in the Republic of Korea, which is about to solve in a super-aged society with more than 20 percent of the elderly aged 65 or older, needs to solve. The impact of knowledge of raising companion animals on the satisfaction level of the elderly was investigated through the management and awareness of infectious diseases. Although the level of care of companion animals had a very significant (p<0.001) effect on the satisfaction of the companion animals, the recognition of infectious diseases has no statistical significance (p>0.05). Raising companion animals with knowledge of rearing increases the satisfaction level and can lead to a happier life. While personal learning is important, it is also believed that supporting education will be necessary as a policy consideration.

Background: As the number of households raising companion dogs increases, the pet genetic analysis market also continues to grow. However, most studies have focused on specific purposes or native breeds. This study aimed to collect genomic data through single nucleotide polymorphism (SNP) chip analysis of companion dogs in South Korea and perform genetic diversity analysis and SNP annotation. Methods: We collected samples from 95 dogs belonging to 26 breeds, including mixed breeds, in South Korea. The SNP genotypes were obtained for each sample using an Axiom^TM Canine HD Array. Quality control (QC) was performed to enhance the accuracy of the analysis. A genetic diversity analysis was performed for each SNP. Results: QC initially selected SNPs, and after excluding non-diverse ones, 621,672 SNPs were identified. Genetic diversity analysis revealed minor allele frequencies, polymorphism information content, expected heterozygosity, and observed heterozygosity values of 0.220, 0.244, 0.301, and 0.261, respectively. The SNP annotation indicated that most variations had an uncertain or minimal impact on gene function. However, approximately 16,000 non-synonymous SNPs (nsSNPs) have been found to significantly alter gene function or affect exons by changing translated amino acids. Conclusions: This study obtained data on SNP genetic diversity and functional SNPs in companion dogs raised in South Korea. The results suggest that establishing an SNP set for individual identification could enable a gene-based registration system. Furthermore, identifying and researching nsSNPs related to behavior and diseases could improve dog care and prevent abandonment.

Extracts from spinach, cabbage, and onion are known to possess various instructive characteristics, including antioxidant and anti-inflammation activities. Spinach, cabbage, and onion are consumed worldwide and represent important sources of dietary phytochemicals with proven antioxidant properties, such as flavonoids and phenolic acids. Food-derived flavonoids and phenolic compounds are expected to be promising drugs for cancer. In the present study, we investigated the effects of methanol extracts of spinach, cabbage, and onion on cell proliferation and apoptosis in human gastric and breast cancer cells. Proliferation rates of AGS, MDA-MB-231, and SK-BR-3 cells were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The methanol extracts of spinach, cabbage, and onion inhibited proliferation of cancer cells in a dose-dependent manner. 4',6-Diamidino-2-phenylindole (DAPI) staining revealed that chromatin condensation significantly increased compared with the control. In the results of MTT assay and DAPI staining, onion extract was the most effective in inhibiting cancer cell proliferation and apoptosis. To assess changes in protein expression level by onion extract, we identified Bax (pro-apoptotic), Bcl-2 (anti-apoptotic), and poly(ADP-ribose) polymerase (PARP) protein by western blot analysis. The expression of Bax and cleaved-PARP increased, whereas expression of Bcl-2 was decreased compared with the control. These results suggest that spinach, cabbage, and onion extracts suppressed growth of human gastric cancer AGS, human breast cancer MDA-MB-231, and SK-BR-3 cells through induction of apoptosis. Among the extracts, onion extract had stronger anti-cancer and apoptosis induction effects than spinach and cabbage extracts. Further, onion extract more effectively induced apoptosis of human gastric cancer cells than human breast cancer cells. Therefore, further studies are needed to determine the anti-cancer effects of onion extracts in vivo. Onion extract can be developed as a chemopreventive or therapeutic agent for gastric cancer.
