目的：确定马驹管理措施、环境管理和预防性卫生措施是否为马驹红球菌肺炎的危险因素。设计前瞻性配对病例对照研究。动物--马场9991匹马匹2,764匹。过程：1997年，参与的兽医完成配对数据收集表格以供比较；1个受影响的马场(包含大于或等于1个马驹引起的肺炎)和1个对照马场。利用条件Logistic回归进行匹配的结果表明，受影响农场的工作人员更有可能接生小马驹、测试小马驹被动免疫的充分性、对小马驹进行血浆或其他治疗以补充血清免疫球蛋白浓度、对小马驹预防性给予高免疫血浆、为母马和小马驹接种马链球菌感染疫苗，以及在驱虫计划中使用多种驱虫药。受影响的农场也更有可能有患上其他呼吸道疾病的小马驹，在用来安置小马驹的摊位上铺泥土的可能性大约是对照农场的4倍。结论和临床相关性-马红球菌肺炎似乎与农场管理不善或缺乏对预防性卫生实践的关注无关。将小马驹关在地板脏兮兮的马厩里，可能会增加患马立克氏肺炎的风险。
Objective-To determine whether foal management practices, environmental management, and preventative health practices are risk factors for development of Rhodococcus equi pneumonia in foals.Design-Prospective matched case-control study.Animals-2,764 foals on 64 equine breeding farms with 9,991 horses.Procedure-During 1997, participating veterinarians completed paired data collection forms for comparison; 1 for an affected farm (containing greater than or equal to 1 foal with pneumonia caused by R equi) and 1 for a control farm. Information collected pertained to stabling facilities, environmental management, foal husbandry, and preventative equine health practices.Results-Matched farm data compared by use of conditional logistic regression indicated that personnel on affected farms were more likely to attend foal births, test foals for adequacy of passive immunity, administer plasma or other treatments to foals to supplement serum immunoglobulin concentrations, administer hyperimmune plasma prophylactically to foals, vaccinate mares and foals against Streptococcus equi infection, and use multiple anthelmintics in deworming programs. Affected farms were also more likely to have foals that developed other respiratory tract disorders and were approximately 4 times as likely to have dirt floors in stalls used for housing foals as were control farms.Conclusions and Clinical Relevance-Rhodococcus equi pneumonia does not appear to be associated with poor farm management or a lack of attention to preventative health practices. Housing foals in stalls with dirt floors may increase the risk for development of R equi pneumonia.
