Infectious upper respiratory disease (IURD) of Thoroughbred racehorses has been a frequent problem (29.6% of incidence) at the Seoul Race Park (Korea). Risk factors for IURD include the season with a high transfer rate (summer and fall), the stabling period (≤ 3 months), and age (2 to 3 years old), suggesting that the movement and new environment may have depressed the immune system of the horses and decreased their ability to respond properly to pathogens. The bacterial strains (n = 98) isolated from IURD horses included Pseudomonas spp., Escherichia coli, Staphylococcus spp., Streptococcus equi subsp. equi and zooepidemicus.
纯种赛马的传染性上呼吸道疾病(IURD)在韩国首尔赛马场一直是个常见问题(发病率为29.6%)。IURD的风险因素包括转移率高的季节(夏季和秋季)、厩养期(≤3个月)和年龄(2至3岁),这表明马匹的移动和新环境可能抑制了它们的免疫系统,降低了它们对病原体的正常反应能力。从患有IURD的马匹中分离出的98株细菌包括假单胞菌属、大肠杆菌、葡萄球菌属、马链球菌马亚种和兽疫链球菌。
