The Rapid Aminoglycoside NP (Nordmann/Poirel) test was developed to rapidly identify multiple aminoglycoside (AG) resistance in Enterobacteriaceae It is based on the detection of the glucose metabolism related to enterobacterial growth in presence of a defined concentration of amikacin plus gentamicin. Formation of acid metabolites was evidenced by a color change (orange to yellow) of the red phenol pH indicator. The Rapid Aminoglycoside NP test was evaluated by using bacterial colonies of 18 AG-resistant isolates producing 16S rRNA methylases, 20 AG-resistant isolates expressing AG-modifying enzymes (acetyl, adenyl and phospho transferases), and 10 isolates susceptible to AG...

BACKGROUND: Local drug delivery devices offer a promising method for delivering vancomycin and amikacin for musculoskeletal wounds. However, current local delivery devices such as beads and sponges do not necessarily allow for full coverage of a wound surface with eluted antibiotics and do not address the need for reducing the antibiotic diffusion distance to help prevent contamination by bacteria or other microorganisms. We blended chitosan/polyethylene glycol (PEG) pastes/sponges to increase biocompatibility and improve antibiotic coverage within the wound...

Mycobacterium abscessus pulmonary infections are treated with a macrolide (clarithromycin or azithromycin), an aminoglycoside (amikacin), and a β-lactam (cefoxitin or imipenem). The triple combination is used without any β-lactamase inhibitor despite production of the broad spectrum β-lactamase BlaMab We determine whether inhibition of BlaMab by avibactam improves the activity of imipenem against M. abscessus. Bactericidal activity of drug combinations was assayed in broth and in human macrophages. The in vivo efficacy of the drugs was tested by monitoring the survival of infected zebrafish embryos...

Hearing loss and nephrotoxicity are associated with prolonged treatment duration and higher dosage of amikacin and kanamycin. In our Tuberculosis Center, we have employed therapeutic drug monitoring (TDM) targeting pre-set pharmacokinetic/pharmacodynamic (PK/PD) surrogate endpoints in an attempt to maintain efficacy while preventing (oto-)toxicity. To evaluate this strategy, we retrospectively evaluated medical charts of TB patients treated with amikacin or kanamycin in the period 2000 - 2012.Patients with culture-confirmed multi- or extensively drug resistant tuberculosis (MDR/XDR-TB) receiving amikacin or kanamycin as part of their TB treatment for at least 3 days were eligible for inclusion in this retrospective study...

OBJECTIVE: Patients with clinical infections caused by the Mycobacterium avium-complex (MAC) are treated for at least one year following sputum conversion with a regimen suffering from suboptimal cure rates. The correlation between clinical outcome and drug susceptibility testing breakpoints other than for the macrolides is regarded to be poor. A systematic evaluation of clinical breakpoints against MAC has not been performed so far and thus our aim was to initiate this process by establishing minimal inhibitory concentration (MIC) distributions...

Amikacin has been one of the important antimicrobial agents against Gram-negative pathogens. However, there is discrepancy regarding the amikacin initial dosage, with some reports recently recommending ≥25 mg/kg and others the conventional dosage (15-20 mg/kg). Hence, we evaluated the optimal initial dosing regimen of amikacin. Pharmacokinetic (PK) parameters were estimated using a population PK analysis. The pharmacodynamic (PD) target was a ratio of ≥8 between the concentration achieved 1 h after beginning the infusion (C peak) and the minimal inhibitory concentration (MIC) of the liable bacteria...

Tuberculosis (TB), caused by infection with Mycobacterium tuberculosis, is an important communicable disease. Various mechanisms of resistance to antituberculosis drugs have been reported; these are principally mutations in target genes. However, not all M. tuberculosis resistance can be explained by mutations in such genes. Other resistance mechanisms associated with drug transport, such as efflux pumps, have also been reported. In this study, we investigated the expression levels of three putative efflux pumps and mutations in target genes associated with injectable agents and fluoroquinolones with clinical MDR and XDR-TB isolates...
