Tetracycline susceptibility testing and resistance genes in isolates of Acinetobacter baumannii-Acinetobacter calcoaceticus complex from a U.S. military hospital.
Infections with multidrug-resistant Acinetobacter baumannii-Acinetobacter calcoaceticus complex bacteria complicate the care of U.S. military personnel and civilians worldwide. One hundred thirty-three isolates from 89 patients at our facility during 2006 and 2007 were tested by disk diffusion, Etest, and broth microdilution for susceptibility to tetracycline, doxycycline, minocycline, and tige...
متن کاملEmergence and spread of plasmid-borne tet(B)::ISCR2 in minocycline-resistant Acinetobacter baumannii isolates.
Resistance to minocycline has emerged in multidrug-resistant Acinetobacter baumannii isolates from Buenos Aires hospitals. Few reports about the description and dispersion of tet genes in this species have been published. We observed the presence of tet(B) in all minocycline-resistant isolates. This gene was found to be associated with the ISCR2 mobile element, which may, in part, explain its d...
متن کاملAssessment of minocycline and polymyxin B combination against Acinetobacter baumannii.
Antimicrobial resistance among Acinetobacter baumannii is increasing worldwide, often necessitating combination therapy. The clinical utility of using minocycline with polymyxin B is not well established. In this study, we investigated the activity of minocycline and polymyxin B against 1 laboratory isolate and 3 clinical isolates of A. baumannii. Minocycline susceptibility testing was performe...
متن کاملIn vitro activity of minocycline alone or in combination in multidrug-resistant Acinetobacter baumannii isolates.
Minocycline (MIN) usually shows good activity against Acinetobacter baumannii strains. The reintroduction to the market of intravenous MIN provides an additional agent to the limited options for the treatment of A. baumannii infections. The activity of MIN as a single agent and in combination with rifampicin (RIF), colistin (COL) or imipenem (IMI) was evaluated by means of killing curves and 24...
متن کاملبررسی فراوانی ژن های blaPER، blaVEB، blaCTX-M، tetA و tetB در ایزوله های بالینی اسینتوباکتر بومانی جدا شده از بیماران بستری در بیمارستان‌های تهران در سال 1396
Background & Aim: Infections and outbreaks caused by multidrug-resistant Acinetobacter baumannii are prevalent and have been reported worldwide over the past twenty or more years. Beta-lactamase genes including blaPER, blaVEB and blaCTX-M confer resistance to beta-lactam antibiotics and tetA and tetB are responsible for resistance to tetracycline in such bacteria. Methods: A total of 65 isolat...
