本文报告2例散发性军团病病人。从痰液标本中分离出了嗜肺军团杆菌,并由血清抗体滴度的升高所证实。在2例病人住宅供水中也分离到了嗜肺军团杆菌。供水中与感染的军团杆菌的血清类型是相同的。例1为3血清型,该型是军团病罕见的病原,而例2经单克隆抗体证实为1血清型。军团病的潜伏期推测为2周以上。例1患慢性淋巴性白血病没有外出;例2因足疾必须在轮椅上不能自由行动,除在发病前2周外出几小时外,都在家中。此外,也未开中心空调或室内空调,因此该2例感染军团病菌系来自住宅供水系统。这是首次报告军团病的发生与住宅供水有关。
This article reports 2 cases of patients with sporadic Legionnaires’ disease. Legionella pneumophila was isolated from sputum samples and confirmed by elevated serum antibody titer. Legionella pneumophila was also isolated from two patients’ residential water supplies. The serotype of Legionella that infects water supplies is the same. Example 1 is serotype 3, which is a rare causative agent of Legionnaires disease, while case 2 is confirmed to be serotype 1 by monoclonal antibodies. Legionnaires disease incubation period speculated that more than two weeks. Example 1 Chronic lymphatic leukemia did not go out; Example 2 because of foot disability must be free to wheelchairs, except for a few hours before the onset of two hours outside, at home. In addition, neither the central air-conditioning nor the room air-conditioners were involved, so the two cases of Legionella infection were from residential water supply systems. This is the first report that Legionnaires’ disease occurs in relation to residential water supply.
