A culture medium for screening 16S rRNA methylase-producing pan-aminoglycoside resistant Gram-negative bacteria

Abstract

The amikacin plus gentamicin-containing SuperAminoglycoside medium was developed for screening multiple-aminoglycoside resistance in Gram-negative bacteria (Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii). It was evaluated using aminoglycoside-susceptible (n=12) and aminoglycoside-resistant (n=59) Gram-negative isolates, including 16S rRNA methylase producers (n=20). Its sensitivity and specificity of detection were, respectively, of 95% and 96% for detecting multiple aminoglycoside-resistant methylase producers.

Antifungals

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.

Antimicrobial Resistance

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.

Aminoglycosides (ASM)

Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside. Discover the latest research on aminoglycoside here.

Acinetobacter Infections

Acinetobacter infections have become common in hospitalized patients, especially in the intensive care unit setting and are difficult to treat due to their propensity to develop antimicrobial drug resistance. Discover the latest research on Acinetobacter Infections here.
