Activity of KRM 1648 alone or in combination with ethambutol or clarithromycin against Mycobacterium avium in beige mouse model of disseminated infection.
Rifamycins are active against slowly growing mycobacteria, such as Mycobacterium tuberculosis and Mycobacterium kansasii, but the majority of rifamycins thus far investigated both in vitro and in vivo are inactive or have only modest activity against the Mycobacterium avium complex (MAC). We investigated the activity of three doses of the semisynthetic benzoxazinorifamycin KRM 1648, alone or in...
متن کاملActivities of roxithromycin used alone and in combination with ethambutol, rifampin, amikacin, ofloxacin, and clofazimine against Mycobacterium avium complex.
Preliminary studies showed that roxithromycin possessed significant in vitro activity against a variety of atypical mycobacteria such as the Mycobacterium avium complex, M. scrofulaceum, M. szulgai, M. malmoense, M. xenopi, M. marinum, and M. kansasii and rare pathogens such as M. chelonae and M. fortuitum. In this investigation, radiometric MICs of roxithromycin, ethambutol, rifampin, amikacin...
متن کاملActivity of KRM-1648 alone or in combination with both ethambutol and kanamycin or clarithromycin against Mycobacterium intracellulare infections in beige mice.
The in vivo activities of KRM-1648 alone or in combination with both ethambutol (EB) and kanamycin (KM) or clarithromycin (CAM) were tested against Mycobacterium intracellulare infections in beige mice. KRM-1648 was more active than rifampin (RFP) when each drug was used alone, and the efficacy of KRM-1648 was similar to those of both kanamycin and clarithromycin. The combination KRM-1648-KM-EB...
متن کاملActivities of isoniazid alone and in combination with other drugs against Mycobacterium avium infection in beige mice.
Monotherapy with isoniazid or amikacin or clarithromycin or combinations of two of these drugs showed nil to modest therapeutic activity in beige mice infected with Mycobacterium avium. However, the combination of all three, isoniazid-amikacin-clarithromycin, markedly reduced CFUs in both spleens and lungs after 91 days of infection.
متن کاملSpectrum of activity of levofloxacin against nontuberculous mycobacteria and its activity against the Mycobacterium avium complex in combination with ethambutol, rifampin, roxithromycin, amikacin, and clofazimine.
The spectrum of activity of levofloxacin was initially determined against 29 strains belonging to 16 species of atypical mycobacteria by measuring radiometric MICs. Levofloxacin MICs were 1 to 2 dilutions lower compared with those obtained for ofloxacin and 8 to 64 dilutions lower compared with those obtained for its D-isomer. Levofloxacin MICs were below its peak level in serum (5.5 micrograms...
