Objective: Today, the public concern for 'Companion Animal" as a family member is ever increasing. Accordingly, the cases of traditional veterinary medicine treatment targeting a companion animal has been increasing, but the traditional records in literature about this have hardly ever been introduced to academic circles. Hereupon, this writing is intending to collect the prescriptions, which were once used for treating canine diseases, in order to report them to academic circles first. Method: This writing recorded the information about canine diseases and their treatment from the books related to the orthodox oriental medicine in East Asia, and analyzed their meanings. Result: Intial records about canine diseases are found in East Asian traditional medicine books including "Bonchoseubyu"(741), "Ilwhajajegaboncho"(unidentifiable period), "Jeungryuboncho"(1082), etc. The disease perceived by humans at that time was "gwa"(a boil) which is a kind of skin ailments. In addition, these medicine books show that people at that time concentrated on the value of use of a dog as meat rather than a pain of a dog's diseases. "Hwalsujaju"(1873)which was established during the Qing Dynasty leaves the most abundant data on canine diseases. This book perceived a dog as a precious existence watching over human housing and property, according to which, canine diseases and treatment methods are subdivided. The prescriptions for a dog's disease in our country are identifiable only in "Jeungbodanbangshinpyeon"(1913)과 "Bijeongmanbyeongtongchibeop"(1933). These books include the prescriptions not only for a dog's disease but also for a disease of a cow, horse, sheep, chicken, and pig, etc. which are familiar to us. Conclusion: The prescriptions used for a dog in East Asia were different from those for people. It was found that they used a medicine noticeably for external application for easy treatment, and in case of the use of an internal medicine, they adopted a method of getting dogs to take a medicine mixed with rice or porridge for dogs. Such a clue will be applied to the traditional- medicine-based treatment of a companion animal for the time to come.

The spread of antibiotic-resistant strains of Staphylococcus aureus, a gram-positive opportunistic pathogen, has increased due to the frequent use of antibiotics. Inhibition of the quorum-sensing systems of biofilm-producing strains using plant extracts represents an efficient approach for controlling infections. Torilis japonica is a medicinal herb showing various bioactivities; however, no studies have reported the anti-biofilm effects of T. japonica extracts against drug-resistant S. aureus. In this study, we evaluated the inhibitory effects of T. japonica ethanol extract (TJE) on biofilm production in methicillin-sensitive S. aureus (MSSA) KCTC 1927, methicillin-resistant S. aureus (MRSA) KCCM 40510, and MRSA KCCM 40511. Biofilm assays showed that TJE could inhibit biofilm formation in all strains. Furthermore, the hemolysis of sheep blood was found to be reduced when the strains were treated with TJE. The mRNA expression of agrA, sarA, icaA, hla, and RNAIII was evaluated using reverse transcription-polymerase chain reaction to determine the effect of TJE on the regulation of genes encoding quorum sensing-related virulence factors in MSSA and MRSA. The expression of hla reduced in a concentration-dependent manner upon treatment with TJE. Moreover, the expression levels of other genes were significantly reduced compared to those in the control group. In conclusion, TJE can suppress biofilm formation and virulence factor-related gene expression in MSSA and MRSA strains. The extract may therefore be used to develop treatments for infections caused by antibiotic-resistant S. aureus.

본 연구에서는 fucoidan이 macrophage의 활성과 항암효과를 확인하기 위하여 수행되었다. Fucoidan을 Raw 264.7 세포에 처리한 후 MTT assay로 측정한 결과 고농도 $100{\mu}g/mL$까지 세포독성은 없었으며, NO 및 TNF-${\alpha}$의 분비를 농도 유의적으로 증가시켰다. 또한 AGS 위암 세포 성장저해효과를 확인하기 위하여 MTT assay를 하였고 그 결과 농도와 시간 의존적으로 암 세포 성장이 유의적으로 감소하였다. Apoptosis로 인해 암 세포 성장이 감소하였는지 확인하기 위하여 DAPI 염색을 한 결과 apoptotic body와 세포질 응축이 시간 의존적으로 증가하는 것을 확인하였다. 또한 fucoidan은 미토콘드리아의 투과율을 향상시키며 미토콘드리아에서 방출되는 cytochrome c의 발현을 증가시켰다. Western blotting의 결과 시간 의존적으로 anti-apoptotic 분자인 Bcl-2와 XIAP 발현 감소와 반대로 pro-apoptotic 분자인 Bax 발현이 증가하였다. Cleaved-caspase-9의 발현이 증가하였으며 Akt의 인산화는 시간 의존적으로 감소하였다. Caspase 억제제인 z-VAD-FMK 처리 시 Bax, caspase-9의 발현을 감소시켜 apoptosis 유도를 억제하였으며 이러한 결과는 caspase가 apoptosis 유도에 중요한 역할을 하는 것으로 나타낸다. 본 실험의 AGS 위암 세포주에서 대조군에 비하여 fucoidan 처리군에서 면역세포 활성 및 AGS 위암 세포주에서 caspase 활성을 통해 apoptosis를 유도하는 것으로 사료된다.

Rapid urbanization and social development have brought about changes in family structure. In urbanized areas, recently the number of dogs that are a majority of companion animals has increased significantly in Korea. Consequently, a lot of friction between the general public who are not fond of dogs and dog owners in public places such as parks has been happening. A lot of countries that are taking a lead role in animal welfare have built dog parks that the general public and dogs can enjoy together. This research starts with the realization that the concept of 'dog park' needs to be introduced in Korea as more and more Koreans own dogs and other pets. This research aims to provide guidance for dog park planning by drawing planning items and analyzing the needs of each item. Total 56 planning items including dog zone, dog playground, and dog training facility, are drawn in this research. There are differences in the needs according to sex, age and the amount of time they spent with their dogs, however overall there is the highest needs in separated area for dogs in parks.

Toxoplasmosis is caused by an obligate intracellular protozoan parasite; Toxoplasma gondii, which is one of the most important zoonotic parasite worldwide. In dogs, the sexual reproductive cycle of T. gondii is lacking, and the animals are not widely consumed as food, but they are vital in the mechanical transmission of the parasite. However, there is no present data on the exposure of stray dogs to T. gondii in Malaysia. The objective of this serological survey was to determine the prevalence of T. gondii antibodies (IgG) and associated factors in stray dogs in East and West Malaysia. Antibodies to T. gondii were determined in serum samples from 222 stray dogs from 6 different states in East and West Malaysia (Peninsular Malaysia) using an Indirect ELISA. The seroprevalence for T. gondii was 23.4% (Confidence interval: CI 17.8-29.2%). Stray dogs from Selangor and Kuala Lumpur had the highest seroprevalence (32.4%; CI 13.2-45.5%) and lowest in those from Penang and Kedah (12.5%; CI 1.3-23.5%). Gender and breed were not associated with T. gondii seropositivity. However, adult dogs were more likely to be seropositive for T. gondii (OR=2.89; CI 1.1-7.7) compared with younger dogs. These results revealed that T. gondii is prevalent in stray dogs in the studied areas in Malaysia, and indicative of the level of environmental contamination of this parasite especially in urban areas.

In contemporary society, the increasing number of pet-owning households has significantly heightened interest in companion animal health, expanding the probiotics market aimed at enhancing pet well-being. Consequently, research into the gut microbiota of companion animals has gained momentum, however, ethical and societal challenges associated with experiments on intelligent and pain-sensitive animals necessitate alternative research methodologies to reduce reliance on live animal testing. To address this need, the Fermenter for Intestinal Microbiota Model (FIMM) is being investigated as an in vitro tool designed to replicate gastrointestinal conditions of living animals, offering a means to study gut microbiota while minimizing animal experimentation. The FIMM system explored interactions between intestinal microbiota and probiotics within a simulated gut environment. Two strains of commercial probiotic bacteria, Enterococcus faecium IDCC 2102 and Bifidobacterium lactis IDCC 4301, along with a newly isolated strain from domestic dogs, Lactobacillus acidophilus SLAM AK001, were introduced into the FIMM system with gut microbiota from a beagle model. Findings highlight the system's capacity to mirror and modulate the gut environment, evidenced by an increase in beneficial bacteria like Lactobacillus and Faecalibacterium and a decrease in the pathogen Clostridium. The study also verified the system's ability to facilitate accurate interactions between probiotics and commensal bacteria, demonstrated by the production of short-chain fatty acids and bacterial metabolites, including amino acids and gamma-aminobutyric acid precursors. Thus, the results advocate for FIMM as an in vitro system that authentically simulates the intestinal environment, presenting a viable alternative for examining gut microbiota and metabolites in companion animals.

Yogurt fermentation is known to be beneficial because it provides a low pH and harsh environment for foodborne pathogens and improves organoleptic properties. Additionally, organic acids produced through fermentation have a good effect on the viscosity and gelling properties of yogurt. Several potential health benefits of probiotic and generally recognized as safe strains have been suggested. Yogurt is the preferred vehicle for delivering probiotics to health-conscious consumers. Therefore, manufacturers of probiotic beverages must comply with the relevant regulations. The development of probiotic yogurt begins with the selection of strains with safety and functional properties of probiotics. The selected probiotic strain should be technically suitable for viability and improve organoleptic quality while maintaining the number of bacteria above the standard value during processing and storage conditions. In addition, the efficacy of probiotic strains contained in yogurt should be investigated, confirmed, and approved according to well-designed clinical trials. Although various methods are used to detect probiotic strains, the recently widely used next generation sequencing method can be actively utilized. In the future, more research should be conducted with the latest methods to identify probiotic functions and accurately detect probiotic strains.

The number of abandoned dogs is increasing with the worsening of the economy and the rising of feed value. It was becoming a serious social problem because of the disease transmission and destruction of natural ecosystems by abandoned dogs been wild animal. In order to solve these problems, companion dogs necessary to secure its own genetic information and to establish the systematic tracking system. Using multiplex-PCR method with 27 microsatellite marker (MS marker) divided 3 set, various alleles occurring to 6 dog breed (Labrador Retriever, German Shepherd, English Springer Spaniel, Belgian Malinois, Jindo Dog, PoongSan Dog) make use of markers to determine allele frequency and heterozygosity. MS marker FH2834 and FH2790 have only two allele and most were found in 13 alleles at FH3381 and FH3399. Average heterozygosity of MS marker is 0.534 and especially, heterozygosity represented the highest value of 0.765 at FH3381. So, it was recognized appropriate allele frequency for individual identification and paternity diagnosis in companion dogs. Using multiplex-PCR method with MS marker, various alleles occurring to dog breed make use of markers to deter mine individual identification and paternity diagnosis, traits associated biomarkers and breed-specific marker for faster, more accurate and ways to reduce the analysis cost. Based on this result, a scientific basis was established to the existing pedigree data by applying genetics additionally. Animal registration system is expected to be conducted nationwide in future. The method expects to very useful this system.

Background: Klebsiella spp. is an important conditional pathogen in humans and animals. However, due to the indiscriminate use of antibiotics, the incidence of antimicrobial resistance has increased. Objectives: The purpose of this study was to investigate antimicrobial resistance in strains of Klebsiella strains and the phylogenetic relatedness of extended-spectrum cephalosporin (ESC)-resistance among Klebsiella strains isolated from clinically ill companion animals. Methods: A total of 336 clinical specimens were collected from animal hospitals. Identification of Klebsiella species, determination of minimum inhibitory concentrations, detection of ESC resistance genes, polymerase chain reaction-based replicon typing of plasmids by conjugation, and multilocus sequence typing were performed. Results: Forty-three Klebsiella strains were isolated and, subsequently, 28 were identified as K. pneumoniae, 11 as K. oxytoca, and 4 as K. aerogenes. Eleven strains were isolated from feces, followed by 10 from ear, 7 from the nasal cavity, 6 from urine, 5 from genitals, and 4 from skin. Klebsiella isolates showed more than 40% resistance to penicillin, cephalosporin, fluoroquinolone, and aminoglycoside. ESCresistance genes, CTX-M groups (CTX-M-3, CTX-M-15, and CTX-M-65), and AmpC (CMY-2 and DHA-1) were most common in the K. pneumoniae strains. Some K. pneumoniae carrying CTX-M or AmpC were transferred via IncFII plasmids. Two sequence types, ST709 and ST307, from K. pneumoniae were most common. Conclusions: In conclusion, this is the first report on the prevalence, ESCresistance genotypes, and sequence types of Klebsiella strains isolated from clinically ill companion animals. The combination of infectious diseases and antimicrobial resistance by Klebsiella in companion animals suggest that, in clinical veterinary, antibiotic selection should be made carefully and in conjunction with the disease diagnosis.
