The objective of present study was to ascertain sex determination for individual identification, parentage control, and sex chromosome anomalies in horse. PCR amplification products of the equine sex determining region of the Y chromosome gene (SRY) and amelogenin gene (AMEL) were detected by using agarose gel electrophoresis. A normal sire and foal II showed 1 SRY band (430 bp) and 3 AMEL (AMELX, AMELY, and AMELX/Y) band, 175 bp, 160 bp, 190 bp, respectively, and a normal dam and foal I showed a single AMELX band (175 bp). These results enables a quick diagnosis for sex determination prior to cytogenetic analysis.

A 3-year-old Thoroughbred mare was referred to J&C Equine Hospital with gestation day 30 twin pregnancy. On transrectal ultrasonographic examination, two similar sized (28 mm) embryonic vesicles, unilaterally fixed in the uterine horn, were detected. Transvaginal ultrasound-guided aspiration (TUGA) was performed for reduction of one embryonic vesicle. Yolk sac and allantoic cavity fluids from one embryonic vesicle were aspirated by a needle guided by using transvaginal ultrasound. The mare continued normal singleton pregnancy after twin reduction and delivered a foal successfully. This is the first case described the clinical use of TUGA in Korea. Clinical use of TUGA in twin reduction after embryonic fixation is recommended for equine clinicians.

Despite vaccination, equine influenza virus (EIV) and equine herpesvirus (EHV) infections still cause highly contagious respiratory diseases in horses. Recently, concurrent vaccination with EIV and EHV was suggested as a new approach; however, there have been no reports of concurrent vaccination with recombinant canarypox EIV and inactivated EHV vaccines. In this study, we aimed to compare the EIV-specific immune responses induced by concurrent administrations of a recombinant canarypox EIV vaccine and an inactivated bivalent EHV vaccine with those induced by a single recombinant canarypox EIV vaccine in experimental horse and mouse models. Serum and peripheral blood mononuclear cells (PBMCs) were collected from immunized animals after vaccination. EIV-specific serum antibody levels, serum hemagglutinin inhibition (HI) titers, and interferon-gamma (IFN-γ) levels were measured by enzyme-linked immunosorbent assay, HI assay, and quantitative polymerase chain reaction, respectively. Concurrent EIV and EHV vaccine administration significantly increased IFN-γ production, without compromising humoral responses. Our data demonstrate that concurrent vaccination with EIV and EHV vaccines can enhance EIV-specific cellular responses in horses.

A 5-year-old Thoroughbred race horse was presented to Busan Korea Racing Authority equine hospital with a 3-year history of a slow-growing left rostral maxillary mass. The location and progressive growth of the mass eventually resulted in poor food prehension, quidding and mouth bit placement. The mass was solitary and hard, and covered by normal smooth oral mucosa. Radiographic examination of the maxillae showed a flocculated and mixed radiolucent lesion protruding outward and displacing the 202 and 203 teeth caudally. The 202 tooth was in normal size and the 203 tooth was hypoplastic on radiography. Under general anesthesia, a partial surgical resection of the mass was performed to minimize functional loss and facilitate prompt return to track. After surgery, there was improvement in food intake, mouth bit placement, and cosmetic appearance. Histopathological examination determined the resected maxillay mass to be an ossifying fibroma. However, there was continued growth of remnant mass in the maxilla. Equine ossifying fibroma is a rare condition and primarily affects the rostral mandible, and less commonly, the maxillae. In this case, the lesion was slow-growing, and caused cosmetic and functional impairments, including poor food intake and reduced trainability. Surgical resection was performed, but the effect of treatment was limited due to advanced size / stage of the tumor. Early dental care is suggested for horse owners to prevent belated identification and improve successful treatment of oral disorders like ossifying fibroma.

본 연구는 한국마사회 동물병원에서 시행한 전신마취 결과를 분석하고 마취 중 후에 발생한 사망률에 영향을 미치는 인자를 찾기 위하여 실시되었다. 총585두의 환마에서 전신마취가 실시되었으며, 수술의 빈도는 정형외과 수술(410)이 가장 많이 실시되었고, 산통 수술(85), 호흡기 수술(45) 순이었다. 585두 중 20두가 마취 중 후에 죽거나 안락사 되었다. 20두 중 14두는 산통 수술을 받았고, 3두는 정형외과 수술, 3두는 호흡기 수술을 받았다. 세부 사망원인으로는 산통 수술에서는 장파열, 호흡기 수술에서는 기도폐색이었다. 정형외과 수술에서는 근육병증, 재골절, 제엽염이 안락사의 원인이었다. 결과적으로 산통 수술과 호흡기 수술 후의 사망률은 정형외과 수술 후보다 높게 나타났다 (p < 0.01). 이상의 결과로부터, 산통수술을 받는 말의 사망률이 가장 높은 것을 확인하였으며, 그 원인은 예후불량에 의한 안락사이었다. 말의 마취 전후 사망률을 낮추기 위하여, 산통 수술을 받는 말은 수술 전후의 집중 관리가 필요하고, 호흡기 수술을 받는 말은 회복 중 주의 깊은 관찰이 추천된다.

This study evaluated the epizootiological characteristics of equine coital exanthema (ECE) in South Korea. A PCR test was used to determine the equine herpesvirus 3 (EHV-3) release period, excretion by suckling foals, morbidity rate, effect on fertility, and onset of breeding partner after treatment. The morbidity rate of ECE based on clinical symptoms was 8.3% (2/24) for stallions and 10.8% (45/416) for mares, and 29 of 45 (64.4%) animals were positive on the PCR test. Ten (22%) broodmares had symptoms before breeding, while 26 (58%) had symptoms after breeding. Nine (20%) mares had uncertain coverage periods and occurrence times. Suckling foals had no clinical findings and EHV-3 was not detected in their nostrils, although it was detected on teasers. No lesions were observed in the clitoral fossa on broodmares, although EHV-3 was detected by PCR. The period of EHV-3 emission was 22~23, 18~19, 6, and 58 days in stallions, broodmares, teasers, and mares with a mixed E. coli-like infection, respectively. ECE had no negative effects on the breeding capability of stallions and no symptoms were observed in broodmares after recovering from ECE.

말전염성빈혈(EIA)은 전세계의 마과동물에서 발생하는 전염병이다. 2005년부터 2011년까지 제주에서 사육되는 말을 대상으로 EIA를 조사하였다. 한국마사회 제주경마공원 동물병원에서 제주마 1,329 마리 및 한라마(제주산마) 8,324 마리 그리고 제주목장의 동물병원에서 Thoroughbred 말 387 마리 등 7년간 총 10,040마리를 효소면역측정법을 이용하여 검사하였다. 조사기간 동안 혈액에서 EIA 항체는 검출되지 않았다. 1985년 이후부터 제주에서 EIA 항체가 검출된 적이 없고, 발병 예도 없었다. 그러므로 제주에는 EIA가 없는 것으로 생각된다.

An 11-year-old thoroughbred post-partum broodmare presented with the symptoms of colic. The physical and clinical examinations indicated a large colon displacement or volvulus. Immediate surgical intervention was performed, and a strangulating large colon volvulus (LCV) was defined as a volvulus of >540° in the counterclockwise direction. After correcting and assessing the gut viability, approximately 80% of the entire large colon was resected and anastomosed using an end-to-end technique. With supportive care after surgery, the horse regained its appetite and vitality without significant clinical complications and was discharged on postoperative day 9. This report presents the first surgical correction using a large colon resection and anastomosis (LCRA) and the critical care for a strangulating LCV in a horse in Korea. This case enhances the current knowledge of clinical LCV and the related considerations for treatment.

Coital exanthema of Thoroughbred horses had occurred firstly in Republic of Korea. This study was performed to evaluate clinical features of coital exanthema, and provide veterinary knowledge to equine practitioner as well as horse farms. The method was clinical, clinical pathology and sexual hormone, electron microscope and libido examination. Five stallions of 27, 45 broodmares of 416 showed clinical symptoms but 124 foals and a teaser did not show any abnormal appearance. Five stallion had papule, pustule, crust around a glans, body of penis, prepuce and remain decolorized spot after treatment. One laceration of glans and 3 gait disorder had been observed but it did not affect libido. Forty-five broodmares localized had papule, pustule, crust, and ulceration around perineal region, vulva, mucocutaneous junction remain decolorized spot after treatment.
