In vitro and in vivo activities of LCB01-0371, a new oxazolidinone.

LCB01-0371 is a new oxazolidinone with cyclic amidrazone. In vitro activity of LCB01-0371 against 624 clinical isolates was evaluated and compared with those of linezolid, vancomycin, and other antibiotics. LCB01-0371 showed good activity against Gram-positive pathogens. In vivo activity of LCB01-0371 against systemic infections in mice was also evaluated. LCB01-0371 was more active than linezo...

In vivo evaluation of antibiotic activity against Mycobacterium abscessus.

BACKGROUND The prognosis of Mycobacterium abscessus infections is poor due to the lack of effective drug treatment. The objective of this study was to set up an animal model suitable to test antibiotic activity against M. abscessus. METHODS The following mouse strains were evaluated: Swiss, BALB/c, C57BL/6, nude, beige, A/J, and GKO. Antibiotic activity was tested for clarithromycin, amikacin...

Impact of β-lactamase inhibition on the activity of ceftaroline against Mycobacterium tuberculosis and Mycobacterium abscessus.

The production of β-lactamases Bla(Mab) and BlaC contributes to β-lactam resistance in Mycobacterium abscessus and Mycobacterium tuberculosis, respectively. Ceftaroline was efficiently hydrolyzed by these enzymes. Inhibition of M. tuberculosis BlaC by clavulanate decreased the ceftaroline MIC from ≥ 256 to 16 to 64 μg/ml, but these values are clinically irrelevant. In contrast, the ceftaroline-...

Rifabutin Is Active against Mycobacterium abscessus Complex

Lung infections caused by Mycobacterium abscessus are emerging as a global threat to individuals with cystic fibrosis and to other patient groups. Recent evidence for human-to-human transmission worsens the situation. M. abscessus is an intrinsically multidrug-resistant pathogen showing resistance to even standard antituberculosis drugs, such as rifampin. Here, our objective was to identify exi...

In vitro activity of TP-271 against Mycobacterium abscessus, Mycobacterium fortuitum, and Nocardia species.

The in vitro activities of TP-271, a novel fluorocycline antimicrobial, against 22 isolates of Mycobacterium abscessus, 22 isolates of Mycobacterium fortuitum, and 19 isolates of Nocardia spp. were studied by a microtiter broth dilution method. The MIC(90)s for M. abscessus, M. fortuitum, and Nocardia spp. were 0.5 μg/ml, 0.03 μg/ml, and 8 μg/ml, respectively. TP-271 was significantly more acti...
