Simultaneous infections with different Legionella spp. have rarely been described in the literature. We now report on seven sporadic cases of legionellosis of which three were simultaneous infections caused by multiple Legionella pneumophila serogroups. Four different legionellae were involved. L. pneumophila serogroup 1, two different types of L. pneumophila serogroup 4, and L. pneumophila serogroup 10 have been identified simultaneously from a lung tissue specimen of one patient. Specimens from two other patients each revealed two different legionellae of serogroups 1 and 4. The existence of different L. pneumophila serogroups in simultaneous infections has not only been documented by identifying the incriminated Legionella spp. by classical methods. In addition, preliminary results of Legionella spp. identification with the novel physical procedure of Fourier transform infrared spectroscopy have been presented to evaluate its possible applicability for routine diagnostic procedures.
文献中很少描述不同军团菌属的同时感染情况。我们现报告7例散发性军团病病例，其中3例为由多个嗜肺军团菌血清群引起的同时感染。涉及4种不同的军团菌。从1例患者的肺组织标本中同时鉴定出嗜肺军团菌血清群1、2种不同类型的嗜肺军团菌血清群4和嗜肺军团菌血清群10。另外2例患者的标本各自显示出血清群1和4的2种不同军团菌。通过经典方法鉴定出致病的军团菌属，不仅证明了同时感染中存在不同的嗜肺军团菌血清群。此外，还介绍了采用傅里叶变换红外光谱这一新型物理方法鉴定军团菌属的初步结果，以评估其在常规诊断程序中的可能适用性。
