A case-control study was performed in South Australia to determine if L. longbeachae infection was associated with recent handling of commercial potting mix and to examine possible modes of transmission. Twenty-five laboratory-confirmed cases and 75 matched controls were enrolled between April 1997 and March 1999. Information on underlying illness, smoking, gardening exposures and behaviours was obtained by telephone interviews. Recent use of potting mix was associated with illness (OR 4.74, 95% CI 1.65-13.55, P=0.004) in bivariate analysis only. Better predictors of illness in multivariate analysis included poor hand-washing practices after gardening, long-term smoking and being near dripping hanging flower pots. Awareness of a possible health risk with potting mix protected against illness. Results are consistent with inhalation and ingestion as possible modes of transmission. Exposure to aerosolized organisms and poor gardening hygiene may be important predisposing factors to L. longbeachae infection.
在南澳大利亚进行了一项病例对照研究，以确定长滩军团菌感染是否与近期处理商业盆栽混合料有关，并研究可能的传播方式。在1997年4月至1999年3月期间，招募了25例实验室确诊病例和75例匹配对照。通过电话访谈获取了有关基础疾病、吸烟、园艺接触和行为的信息。仅在双变量分析中，近期使用盆栽混合料与疾病有关（比值比4.74，95%可信区间1.65-13.55，P=0.004）。多变量分析中疾病的更好预测因素包括园艺后洗手习惯差、长期吸烟以及靠近滴水的悬挂花盆。意识到盆栽混合料可能存在健康风险可预防疾病。结果与吸入和摄入作为可能的传播方式一致。接触雾化生物和园艺卫生差可能是长滩军团菌感染的重要易感因素。
