The serostatus of enzootic bovine leukosis (EBL) was determined at three dairy farms and the Al Ain Livestock Market (AALM), within the Al Ain region of Abu Dhabi, UAE. Of the 957 bovine sera tested by ELISA, 657 were from Holstein-Friesians from three dairy farms, and 300 from Bos indicus cattle at AALM. The chi-square homogeneity test (CSHT) and the Marascuilo multiple comparison procedure (MMCP) assessed the level of significance between the proportions of EBL-seropositive cattle (ESPC) across the study farms and AALM, and between the age groups at farms 1 and 3. Overall, the proportion of ESPC was 25.7% at dairy farms and AALM, 37.0% for farms and 1.0% for AALM. Furthermore, the proportions of ESPC at farms 1, 2 and 3 were 54.7%, 0.0% and 26.3% respectively, and statistically significant differences were seen across the farm/farm and farm/AALM comparisons, and between two age groups at farms 1 and 3. The 37–72-month-old age group showed the highest proportion of ESPC. This is the first serological evidence of EBL in the UAE. As previously reported, the ESPC are comparatively higher in dairy than Bos indicus cattle. Molecular and more extensive serological studies are needed to further corroborate the present data. Meanwhile, the UAE veterinary authorities will need to formulate national EBL control policies.

在阿拉伯联合酋长国阿布扎比的艾因地区的三个奶牛场和艾因牲畜市场（AALM）确定了牛源性牛白血病（EBL）的血清状况。通过ELISA检测的957份牛血清中，有657份来自三个奶牛场的荷斯坦-弗里斯兰人，有300份来自Bos indicus在ALAM的牛。卡方均一性检验（CSHT）和Marascuilo多重比较程序（MMCP）评估了研究农场和AALM中EBL血清阳性牛（ESPC）的比例以及农场1和2之间年龄段之间的显着性水平。 3.总体而言，奶牛场和AALM中ESPC的比例为25.7％，农场为37.0％，AALM为1.0％。此外，农场1、2和3的ESPC比例分别为54.7％，0.0％和26.3％，并且在农场/农场和农场/ AALM的比较之间以及农场1和2的两个年龄组之间，差异具有统计学意义。 3. 37-72个月大的年龄段的ESPC比例最高。这是阿联酋EBL的第一个血清学证据。如先前报道，乳制品行业的ESPC相对高于老板印度牛。需要分子学和更广泛的血清学研究来进一步证实当前数据。同时，阿联酋兽医当局将需要制定国家EBL控制政策。
