Two 4-day-old Thoroughbred foals with acute clinical signs of depression, elevated pulse and respiratory rates, anemia, and jaundice were referred to the equine hospital of Korea Racing Authority. The foals were seemingly normal at birth, but showed clinical signs such as abnormal behavior, jaundice and anemia suddenly after ingestion of the mare's colostrum, followed by death at 4 days after birth. According to the results of the hematology, serum chemistry analysis, jaundice foal agglutination test, and blood groups test, the foals were diagnosed as neonatal isoerythrolysis (NI) caused by the mare's antibodies. These results suggested that the pregnant mares have a potential for NI.

This study was carried out to investigate the blood groups(Aa, Ca, Dc, Qa, Ua) and antierythrocyte antibody associated with neonatal isoerythrolysis(NI) in Thoroughbred horses. The blood groups from 1,351(35 stallions, 1,316 mares) Thoroughbred horses tested by serological procedures, and antierythrocyte antibody from 52 mares by indirect antiglobulin test. The blood groups(factor) of Aa, Ca, Dc, Qa and Ua positive were 97.1%, 100%, 91.4%, 82.9%, and 17.1% in stallions, respectively, and were negative 3.5%, 6.2%, 25.1%, 18.3%, and 77.1% in mares, respectively. These mares are considered to be at risk for production of an NI foals. The antierythrocyte antibody was not detected by this technique in all mares. These results suggest that the all breeding mares without blood groups Aa(3.5%) and Qa(18.3%) should be selected a appropriate stallion to prevent of neonatal isretythrolysis during the breeding season in Thoroughbred horses.

본 연구의 목적은 제주도 내 더러브렛 경주마에서 신생마 동종면역성 적혈구 용혈증과 가장 밀접한 연관이 있다고 보고된 적혈구 항원 Aa, Ca, Qa의 발현 빈도를 확인하고자 하였다. 본 실험은 제주도 내에서 사육되고 있는 종빈마와 종모마 총 262두의 혈액에서 분리한 2% 적혈구 부유액이 사용되었으며, 간접 항체 검사을 통해 결과를 확인하였다. 226 두의 종빈마 중 Aa 음성이 9 두 (3.98%), Ca 음성이 8 두 (3.54%), Qa 음성이 17두 (7.52%)로 나타났으며, 36 두의 종모마 중 Aa 음성이 1두 (2.78%), Ca 음성이 3두 (8.33%), Qa 음성이 3두 (8.33%)로 확인되었다. 이들 결과를 토대로, 향후 말 번식에 있어서 종부 파트너 선택에 중요한 기초 자료를 제시하고 나아가 신생마 동종면역성 용혈성 빈혈 예방에 기여할 것으로 기대된다.

To determine the distribution of feline blood types and then to estimate the risk of neonatal isoerythrolysis (NI) in non-pedigree cats, we typed blood of 482 cats of both genders and various breeds (336 domestic shorthair cat and 146 pedigree) from August 2005 through July 2007. Blood samples from Seoul and Kangwon province were typed within 5 days after collection by the simple tube method. High-titer anti-A antiserum and anti-B reagent, prepared with Triticum vulgaris lectin, were used to determine type A and type B blood, respectively. The majority of cats were type A (n = 465, 96.5%) and only 3.5% (n = 17) were type B. No type AB blood were detected. Blood type distributions among the non-pedigree and pedigree cats were similar: for non-pedigree cats, 96.4% were type A and 3.6% were type B, whereas for pedigree cats, 96.6% were type A and 3.4% were type B. All type B cats had a very strong agglutination reaction to anti-A antiserum: 8 sample for 3+ and 9 for 4+. Assuming 19% of estimated frequency for the type-B allele in domestic cats, the calculated proportion of random mating from this population at risk for developing NI was 3.4%. Based on this finding, it is strongly recommended that blood typing be performed prior to any blood transfusion or breeding to minimize blood type incompatibilities. Further comprehensive studies on the titer of naturally occurring antibodies in cat populations in Korea and the prevalence of possible NI in practice are clearly required.
