摘要

嗜麦芽霉单胞菌(S. maltophilia)是一种具有内在耐药性并能形成生物膜的细菌,可引起免疫力低下人群的感染。本研究报告了从巴西圣保罗患有牙周炎的艾滋病患者的唾液和牙龈缝隙液(GCF)中分离出的五株嗜麦芽单胞菌,这些菌株对头孢唑肟有耐药性,具有很强的生物膜形成能力,而且基因关系密切。在艾滋病和牙周炎患者的唾液和牙龈龈沟液中发现嗜麦芽糖酵母菌菌株,令人担忧口腔环境中会存在耐药细菌并持续存在,从而增加免疫力低下患者发生严重感染的风险。

ST88 ceftazidime-resistant Stenotrophomonas maltophilia is present in the saliva and gingival crevicular fluid of patients with periodontitis and AIDS from São Paulo State, Brazil.

Stenotrophomonas maltophilia (S. maltophilia) is an intrinsically drug-resistant and biofilm-forming bacteria causing infections in immunocompromised humans. This study reports the isolation of five S. maltophilia strains from saliva and gingival crevicular fluid (GCF) of AIDS patients with periodontitis in São Paulo, Brazil, showing resistance to ceftazidime, strong biofilm formation capacity and a close genetic relationship. The presence of S. maltophilia strains in saliva and CGF of patients with AIDS and periodontitis is a concern for the presence and persistence of intrinsically resistant bacteria in the oral environment, enhancing the risk for the development of severe infections in immunocompromised patients.
