Serum samples of 107 dentists, dental assistants, and dental technicians, working in practices or out-patient clinics, were examined with an indirect immunofluorescence test for antibodies to Legionella pneumophila (SG1-SG6, polyvalent). Serum samples of 106 non-medical workers served as a control. Thirty-six (34%) employees of the dental personnel from 13 practices showed a positive reaction, 24 of these had a weakly reactive titer of 1:32 to 1:64 and 12 a higher titer of 1:128 to 1:256. Dentists had the highest prevalence (50%) of L. pneumophila antibodies, followed by assistants (38%) and technicians (20%). Only 5 samples (5%) from the control group were positive (4 between 1:32 and 1:64, 1 at 1:256). Antibodies could be demonstrated in the dental personnel only after a 1.5-year period of employment ("exposition time"). These results indicate that dentists and dental personnel are at an increased risk of legionella infection.
对在诊所或门诊工作的107名牙医、牙科助理和牙科技术人员的血清样本进行了检测，采用间接免疫荧光试验检测嗜肺军团菌（SG1 - SG6，多价）抗体。106名非医务人员的血清样本作为对照。来自13家诊所的36名（34%）牙科人员血清反应呈阳性，其中24人的反应滴度较弱，为1:32至1:64，12人的滴度较高，为1:128至1:256。牙医中嗜肺军团菌抗体的患病率最高（50%），其次是助理（38%）和技术人员（20%）。对照组中只有5个样本（5%）呈阳性（4个在1:32至1:64之间，1个为1:256）。牙科人员只有在工作1.5年后（“暴露时间”）才能检测到抗体。这些结果表明，牙医和牙科人员感染军团菌的风险增加。
