Out of 1961 patients with the clinical diagnosis of atypical pneumonia 11 cases (0.65%) of recent Legionella infections were diagnosed by indirect immunofluorescence test (IFA). A higher incidence (1.37%) has been found in 364 patients in whom clinicians suspected a Legionella infection and therefore asked for serological testing. Prevalence of antibodies (greater than or equal to 1:32) reacting with antigens of L. pneumophila serogroup 1 to 6 was highest to serogroup 6 (37%), and lowest to serogroup 1 (4.3%). Specificity of IFA for reciprocal titer of 128 to L. pneumophila serogroup 1 was calculated with 99.5%, for serogroup 6 with only 87.7%. Morbidity of severe Legionella pneumonias in Austria can be estimated at about 1.5 cases per 100 000 inhabitants.
在1961例临床诊断为非典型肺炎的患者中，通过间接免疫荧光试验（IFA）诊断出11例（0.65%）近期军团菌感染。在364例临床医生怀疑有军团菌感染并因此进行血清学检测的患者中，发现了更高的发病率（1.37%）。与嗜肺军团菌血清型1至6抗原发生反应的抗体（大于或等于1:32）的流行率，血清型6最高（37%），血清型1最低（4.3%）。IFA针对嗜肺军团菌血清型1的128倍 reciprocal titer的特异性计算为99.5%，针对血清型6仅为87.7%。奥地利严重军团菌肺炎的发病率估计约为每10万居民1.5例。
