Today Mycobacterium avium and Mycobacterium tuberculosis multidrug resistance are responsible for frequent and severe infections in humans and especially in AIDS patients. Irloxacin is a new quinolone derivative, and shows greater activity with an acid pH. It has a good in vitro antimicrobial spectrum against both gram-positive and gram-negative bacteria. We have compared the in vitro activity of irloxacin against mycobacteria (20 M. tuberculosis, 17 M. avium, 5 Mycobacterium bovis, 5 Mycobacterium chelonae, 5 Mycobacterium fortuitum and 1 Mycobacterium gadium) using the Bactec at pH 6.8 and 5.0, with other quinolones (ofloxacin, ciprofloxacin, pefloxacin and 27753 RP). All quinolones tested showed good activity against mycobacteria at pH 6.8 and 5.0. Irloxacin at pH 5.0 had a greater activity against M. avium.

Irloxacin and E-3846 are two new fluorinated quinolones. We evaluated the activities of these antimicrobial agents, ciprofloxacin, ofloxacin, enoxacin, pefloxacin, norfloxacin, and nalidixic acid against 1,161 bacterial strains. Ciprofloxacin was the most active quinolone. Irloxacin did not show great activity. The activity of E-3846 against gram-negative bacteria was similar to those of ofloxacin and pefloxacin, and E-3846 was the most active quinolone against gram-positive bacteria and anaerobes.

The in-vitro activities of eight new quinolones (A-56620, amifloxacin, difloxacin, CI-934, enoxacin, irloxacin, pefloxacin, temafloxacin), two reference fluoroquinolones (ciprofloxacin and ofloxacin) and fusidic acid against 147 mycobacterial strains, belonging to seven different species, were compared. Temafloxacin, ofloxacin and ciprofloxacin were the most active compounds. They only showed consistent activity against Mycobacterium tuberculosis, M. malmoense and M. fortuitum, but not against M. chelonei, M. avium, M. intracellulare and M. scrofulaceum. However, individual strains of these species were sometimes susceptible. The best overall in-vitro activity was obtained with temafloxacin, which often showed activity where other products were inactive. Fusidic acid merely displayed good activity against M. tuberculosis (MIC90 16 mg/l).
