To estimate the prevalence of carriage of methicillin-resistant Staphylococcus aureus (MRSA) among Australian veterinarians.
Individuals attending veterinary conferences in Australia in 2009 were recruited to provide nasal swabs and complete a questionnaire about their professional activities. Swabs were processed by standard methods for detecting MRSA and questionnaire responses were used to group veterinarians according to their areas of major work emphasis (species and practice type). Prevalence was estimated for each of these grouping and contingency tables and regression tree analysis used to explain the variation in MRSA carriage.
Among the 771 respondents 'industry and government veterinarians' (controls) had the lowest prevalence of MRSA carriage at 0.9%. Veterinarians with horses as a major area of work emphasis had a prevalence of 11.8% (13-fold that of controls) and those whose only major emphasis was horses had a prevalence of 21.4% (23-fold that of controls). Veterinarians with dogs and cats as a major activity had a 4.9% prevalence (5-fold that of controls). Prevalence rates for other major activities (pigs, dairy and beef cattle, avian and wildlife) were also increased, but were estimated from smaller numbers of respondents. Regression tree analysis clearly isolated equine veterinarians and dog and cat practitioners as groups at increased risk of carriage of MRSA.
Carriage of MRSA is a notable occupational health issue for veterinarians in clinical practice in Australia, particularly those who work with horses.
评估澳大利亚兽医中耐甲氧西林金黄色葡萄球菌（MRSA）的携带率。
招募2009年参加澳大利亚兽医会议的人员，采集鼻拭子并完成一份关于其专业活动的问卷。拭子采用检测MRSA的标准方法进行处理，问卷回复用于根据兽医的主要工作重点领域（物种和执业类型）对其进行分组。对这些分组以及列联表分别估计携带率，并使用回归树分析来解释MRSA携带情况的差异。
在771名受访者中，“行业和政府兽医”（对照组）的MRSA携带率最低，为0.9%。主要工作重点为马的兽医携带率为11.8%（是对照组的13倍），仅主要重点为马的兽医携带率为21.4%（是对照组的23倍）。主要活动为犬猫的兽医携带率为4.9%（是对照组的5倍）。其他主要活动（猪、奶牛和肉牛、禽类和野生动物）的携带率也有所增加，但估计是基于较少的受访者得出的。回归树分析明确将马兽医以及犬猫从业者列为MRSA携带风险增加的群体。
对于澳大利亚临床实践中的兽医，尤其是从事马相关工作的兽医来说，MRSA携带是一个显著的职业健康问题。
