Abstract

Serum samples from 107 dentists, dental assistants, and dental technicians were examined with an indirect immunofluorescence test for antibodies to Legionella pneumophila SG1-SG6, L. micdadei, L. bozemanii, L. dumoffii, L. gormanii, L. jordanis, and L. longbeachae SG1 + 2. Thirty-six (34%) employees from dental personnel from 13 practices showed a positive reaction for antibodies to Legionella pneumophila. Only five samples (5%) from a control group (non-medical workers) were positive. Of the 36 positive serum samples, 13 (36%) reacted with Serogroup 6, 12 with SG 1 (33%), 12 with SG 5 (33%), and three with SG 4 (8%), and eight samples were positive for antibodies to other Legionella species. Dentists had the highest prevalence (50%) of L. pneumophila antibodies, followed by assistants (38%) and technicians (20%). These results indicate that dental personnel are at an increased risk of legionella infection.

摘要

对107名牙医、牙科助手和牙科技术人员的血清样本进行了间接免疫荧光检测，以检测抗嗜肺军团菌1型至6型、米克戴德军团菌、博兹曼军团菌、杜莫夫军团菌、戈尔曼军团菌、约旦军团菌和长滩军团菌1型+2型的抗体。来自13家医疗机构的牙科人员中有36名（34%）员工的抗嗜肺军团菌抗体呈阳性反应。对照组（非医务人员）中只有5份样本（5%）呈阳性。在36份阳性血清样本中，13份（36%）与6型血清群反应，12份与1型血清群（33%）反应，12份与5型血清群（33%）反应，3份与4型血清群（8%）反应，8份样本针对其他军团菌属的抗体呈阳性。牙医中嗜肺军团菌抗体的患病率最高（50%），其次是助手（38%）和技术人员（20%）。这些结果表明，牙科人员感染军团菌的风险增加。
