We describe here a rare case of traumatic myiasis occurred in August 2014, caused by an association of 2 Diptera species, Sarcophaga tibialis Macquart (Diptera: Sarcophagidae) and Lucilia sericata (Meigen) (Diptera: Calliphoridae), in a domestic cat in northern Italy. Species identification was based on adult male morphology. The present case is the first report of S. tibialis as an agent of myiasis in Italy, and also the first ever report of myiasis caused by an association of S. tibialis and L. sericata. The cat developed an extensive traumatic myiasis in a large wound on the rump, which was treated pharmacologically and surgically. The biology, ecology, and distribution of S. tibialis and L. sericata are also discussed. A literature review is provided on cases of myiasis caused by S. tibialis, and cases of myiasis by L. sericata involving cats worldwide and humans and animals in Italy.

As the number of companion animals reaches 15 million in 2022, the pet wear market is expected to grow at an average annual rate of about 14.5% from KRW 1.5684 trillion in 2014 to a market size of over KRW 6 trillion in 2027. However, most of the pet clothing and various supplies currently in circulation are either cheap, low-quality products imported from China or other countries, or expensive products released by overseas luxury brands. Therefore, it is urgent to develop a brand that can compete with luxury products coming from overseas by developing premium pet fashion products using high-end functional fabrics produced domestically. This study seeks to propose ways to revitalize the domestic pet fashion market by examining the current status of global pet fashion, the domestic textile industry, and the current status of the pet fashion market. The suggestions and expected effects are as follows. First, active support is needed for the development of products using domestically produced fabrics, such as raising awareness through various subsidy projects and contests. Second, it is expected that small and medium-sized businesses will be revitalized through the production of pet fashion products using high-quality functional knit fabrics produced in northern Gyeonggi Province. Third, it is necessary to produce high-quality premium products through continuous and intensive support from the government and collaboration between large corporations and small and medium-sized enterprises. Fourth, there is an urgent need to provide opportunities to train experts for the expected effects of starting businesses and creating new jobs.

African swine fever (ASF) is fatal to domestic pigs and wild boars (Sus scrofa) and affects the domestic pig industry. ASF is transmitted directly through the secretions of infected domestic pigs or wild boars, an essential source of infection in disease transmission. ASFV is also very stable in the environment. Thus, the virus is detected in the surrounding environment where ASF-infected carcasses are found. In this study, ASF infection monitoring was conducted on the swab and whole blood samples from wild animals, various hematopoietic arthropod samples that could access infected wild boar carcasses or habitats to cause maintenance and spread of disease, and soil samples of wild boar habitats. ASF viral DNA detection was confirmed negative in 317 wildlife and environmental samples through a real-time polymerase chain reaction. However, ASF occurs in the wild boars and spreads throughout the Korean peninsula. Therefore, it is necessary to trace the route of ASF virus infection by a continuous vector. Additional monitoring of various samples with potential ASF infection is needed to help the epidemiologic investigation and disease prevention.

Bovine oocytes with compact and complete cumulus cells were cultured in 6 groups for up to 24h in TCM199 buffered with 25 mmol/1 HEPES and supplemented with 10% FCS, 1 mg/ml $17{\beta}$-estradiol, 20 IU/ml hCG. Half of the oocytes at each group cultured in the presence of $25{\mu}g/ml$ cycloheximide at different times during maturation (0, 6, 12, 18, 20, 22 h) were fixed at 24 h of maturation to examine the nuclear progression. The rests of them were inseminated with frozen-thawed spermatozoa in medium BO with 10 mg/ml BSA and 10 mg/ml heparin and fixed after additional 18-20 h culture to evaluate the sperm head transformation. When a protein synthesis inhibitor was added at the onset of the maturation, the oocytes were prevented to proceed GVBD. A few of the oocytes (16%) were able to be penetrated and sperm head decondensation was inhibited either. Addition of cycloheximide after 6-12 h of culture resulted in an increasing percentage of GVBCD (more than 80%), but the oocytes became arrested in M-I (69.2%). More than half of the oocytes was penetrated with a decondensing sperm head. Formation of male pronucleus was first obtained at 12 h of culture in the presence of cycloheximide. When cycloheximide was added from 18 h of culture onwards, nuclear progression to M-II was increasingly restored (80.4-85.5%). The proportion of male and female pronuclear formation increased from 17.9% to 46.2%. It is concluded that protein synthesis is necessary not only for GVBD and development from M-I to M-II, but also for sperm head decendensation and male pronuclear formation in bovine oocytes.

The present study was conducted to investigate the phage types(PT) of Salmonella enteritidis(SE) isolated from animals and human patients in Korea during the period 1993-1999. SE were isolated from chickens including the layer and broiler, duck, rat, swine and human patients in nationwide scale. A total of 231 non-human and 14 human SE strains were phage typed and 80.4%(197/245) of SE isolates tested could discriminate as a ten SEPTs including the RDNC by the 10 standard phages, which were brought from the Central Public Health Laboratory in England. In analysing of phage types both animal and human SE isolates, SEPT 4(55.4%) was the most prevalent in domestic animals including the layer(39.3%) and broiler(64.5%), duck(55.5%), and swine(75.0%) since 1993. About 57% of the S enteritidis from human was SEPT 4. Along with SEPT 4, SEPT 1, SEPT 6a, SEPT 7 and SEPT 7a var, SEPT 9b, SEPT 15, SEPT 21b and SEPT 22 were also found from animal and human SE isolates. SEPT 4(40.0%) was isolated from frozen chicken meats imported from China along with SEPT 7 and 7a var strains in this study. In conclusion, SEPT 4 was the most predominant SEPT in our country regardless of animal or human hosts including the Che-Ju island and almost exclusively found in domestic poultry(layer and broiler). During the review period, SEPT 4 has already been spreading continually among the animal hosts since 1993.

We generated 16,993 expressed sequence tags (ESTs) from two libraries containing full-length cDNAs from the brain and liver of the Korean Jindo dog. An additional 365,909 ESTs from other dog breeds were identified from the NCBI dbEST database, and all ESTs were clustered into 28,514 consensus sequences using StackPack. We selected the 7,305 consensus sequences that could be assembled from at least five ESTs and estimated that 12,533 high-quality single nucleotide polymorphisms (SNPs) were present in 97,835 putative SNPs from the 7,305 consensus sequences. We identified 58 Jindo dog-specific SNPs in comparison to other breeds and predicted seven synonymous SNPs and ten non-synonymous SNPs. Using PolyPhen, a program that predicts changes in protein structure and potential effects on protein function caused by amino acid substitutions, three of the non-synonymous SNPs were predicted to result in changes in protein function for proteins expressed by three different genes (TUSC3, ITIH2, and NAT2).

In this study, we investigated the number of categories of veterinary medical devices registered by Animal and Plant Quarantine Agency (QIA) by 2013. We also analyzed the sales of the veterinary medical devices reported from Korea Animal Health Product Association (KAHPA) from 2011 to 2013. The registration rate of veterinary medical devices has sharply increased since 2008, and a total of 495 categories from 141 companies were registered by the end of 2013. The multi-frequency products registered for companion animals were ultrasound imaging system, x-ray system, microchip & reader, telemetry system transmitter, and hematology analyzer. The veterinary medical devices for farm animals include marker, artificial insemination catheter, injector, and ultrasound imaging system. Of these products, the multi-frequency products dominated on the veterinary medical devices market. The market size of 223 (45.0%) veterinary medical devices was estimated to be approximately 20.6 billion Won in 2013; the proportion of domestic products and imports was 56% to 44%; the proportion of domestic demand and export was 82% to 18%, respectively. This study suggested that the registration and sales of the veterinary medical devices have gradually increased as the demand of health care services got bigger in Korea.

Yersinia enterocolitica is an inhabitant in the lower intestinal tract of many domestic and wild animals as well as in the nature. Of the several forms of diseases caused by Y. enterocolitica, an acute enteritis, especially in young children, is the most common form. Infection of the bacteria usually occurs through fecal-oral route by contaminated foods or water, especially mountainspring water. Of the domestic animals, swine has been known as one of the most important carrier in the human infection. Based on the knowledge, prevalence of antibody against Y enterocolitica was investigated with swine sera collected from Korea for the survey of Y enterocolitica infection in swine. As the first step of this survey, we analyzed outer membrane protein (OMP) profiles of the representative strains of Y enterocolitica isolated from the feces of piglets and mountainspring water in Korea. Thirty-eight kDa OMP was identified as the common OMP regardless of origin, serotype, or biotype of Y enterocolitica isolates. Presence of antibody specific for 38 kDa OMP of Y enterocolitica in 1,076 swine sera collected from November 1999 to October 2000 was analysed with ELISA. Antibody titer in sows was significantly higher than that in piglets, growing pigs and finishing pigs (p<0.05). Also, there was seasonal difference in the prevalence of antibody against Y enterocolitica. These results would provide the basic knowledge for controlling the Y enterocolitica infection in human as well as swine.

These studies were carried out to develop non-contact thermometer to take easily the body temperature of domestic animals instead of taking rectal temperature. For the studies, 86 cattle, 57 horses, 72 pigs, 43 goats, and 42 dogs were used and body parts as neck, flank, axilla, lateral abdomen, gluteus, inguinal region, or jugular groove were chosen for taking temperature according to different species. Two types of commercial non-contact thermometers were used to take the temperature of certain body part and at the same time the rectal temperature using digital thermo-meter was taken to compare the difference of temperature between rectum and certain body part. The difference of mean temperature in cattle between rectum and axilla and flank were 0.52 and $2.41^{\circ}C$, respectively, using non-contact thermometer I, whereas $3.02^{\circ}C$ between rectum and flank using thermometer II. The difference of mean temperature in horses between rectum and axilla, gluteus, and jugular groove were 0.52, 1.49, and $0.26^{\circ}C$, respectively, using thermometer I, whereas 2.28 ane $0.92^{\circ}C$ between rectum and gluteus or jugular groove using thermometer II. The difference of mean temperature in swine between rectum and flank, inguinal region, and neck were 1.23, 0.21, and $0.8^{\circ}C$, respectively, using thermometer I, whereas 1.42, 0.711, and $1.25^{\circ}C$ using thermometer II The difference of mean temperature in goats between rectum and lateral abdomen and inguinal region were 1.02 and $0.12^{\circ}C$, respectively, using thermometer I, whereas 1.96 and $1.01^{\circ}C$ using thermometer II. The difference of mean temperature in dogs between rectum and lateral abdomen, inguinal region, and neck were 3.26, 0.24, and $2.37^{\circ}C$, respectively, using thermometer I, whereas 3.45, 0.56, and $2.61^{\circ}C$ using thermometer II.

The fatty acid composition of muscle were investigated to compare muscle composition among the 9 domestic animals including cattle. In major domestic animals, analyzed the effects of age, part and sex of the animal on their fatty acid composition. The content of 4 types of major fatty acids of muscle was determined and calculated their ratio. Myristic acid and palmitic acid levels were high in chicken and sheep. Besides dog muscle contained a lot of stearic acid. Linoleic acid content showed evident difference in the content depending on the animal species. The ratios of linoleic acid/palmitic acid (L/P ratio) and linoleic acid/stearic acid(L/S ratio) were characteristically high in horse and pig, whereas the ratio of palmitic acid/stearic acid(P/S ratio) was $0.71{\pm}0.17$, showing very low level in dog. As for the content of stearic acid, in cattle and chicken it was higher in young animal than adults. In duck, the contents of all fatty acids and ratio were increased by the age. As for the content of fatty acids according to the part of chicken, high level was shown in thigh than in breast and wing, while there was no remarkable variation by the part in other animal. The differences in the content of myristic acid, palmitic acid and linoleic acid among some animal could be verified in muscle lipid composition. The L/P ratio which maintained certain level regardless of age, part, sex shown distinctive pattern between the species.
