We investigated recreational vehicle (RV) water reservoirs in response to a case of pneumonia in which Legionella pneumophila was cultured both from the patient and a RV reservoir in which he travelled. Water samples processed and cultured at the CDC according to standard protocol were positive for Legionella spp. in 4/17 (24%) faucets, 1/11 (9%) water tanks from 4/20 (20%) RVs from three different campsites. Legionella spp. that were isolated included L. pneumophila (serogroups 1 and 6), L. anisa, L. feeleii, and L. quateriensis. Environmental controls from the potable water of the three campsites were culture-negative. A survey of maintenance practices by the RV users at the campsites revealed that chlorine disinfection of the water tanks was rarely performed. To prevent the possibility of Legionella infections, RV owners should implement regular chlorine disinfection of their water tanks and follow the recommended maintenance guidelines according to their owner's manuals.
我们针对一起肺炎病例对休闲车（RV）储水箱展开了调查，该病例中患者以及他乘坐的RV储水箱均培养出嗜肺军团菌。按照标准规程在疾病控制与预防中心（CDC）处理和培养的水样，在来自三个不同露营地的4/20（20%）辆RV的4/17（24%）个水龙头、1/11（9%）个水箱中嗜肺军团菌属呈阳性。分离出的嗜肺军团菌属包括嗜肺军团菌（血清型1和6）、阿氏军团菌、费氏军团菌和夸氏军团菌。三个露营地饮用水的环境对照培养结果为阴性。对露营地RV使用者维护做法的一项调查显示，水箱很少进行氯消毒。为防止军团菌感染的可能性，RV车主应定期对其水箱进行氯消毒，并根据车主手册遵循推荐的维护指南。
