Fifty-five homes in the Pittsburgh area were surveyed for the presence of Legionella pneumophila colonization. Hot water tanks, faucets, and showerheads were sampled. Six homes yielded Legionella pneumophila within the water distribution system. Lower water temperatures (less than 48.8 degrees C) within the hot water system were significantly associated with the presence of L. pneumophila colonization. A similar association was found for electric heaters; however, this association may be an indirect one. Water temperatures in electrically heated tanks were significantly lower than in gas-heated tanks. City residences were also more likely to be colonized than suburban residences. Because acquisition of Legionnaires' disease in the community has been linked to colonization of the water supplies in the homes of affected patients, these findings may have clinical implications for susceptible individuals residing in homes with water supplies colonized by L. pneumophila.
对匹兹堡地区的55户家庭进行了调查，以检测是否存在嗜肺军团菌定植情况。对热水箱、水龙头和淋浴喷头进行了采样。有6户家庭的配水系统中检测出嗜肺军团菌。热水系统中较低的水温（低于48.8摄氏度）与嗜肺军团菌定植显著相关。电热水器也存在类似关联；然而，这种关联可能是间接的。电加热水箱中的水温显著低于燃气加热水箱。城市住宅比郊区住宅更易出现定植情况。由于社区中获得军团病与受影响患者家中供水系统的定植有关，这些发现可能对居住在嗜肺军团菌定植供水家庭中的易感个体具有临床意义。
