Laboratory survey of fluoroquinolone activity.
Fluoroquinolones are active against a wide variety of bacteria. The antibacterial spectra of fluoroquinolones encompass staphylococci, Bacillus species, and Corynebacterium species implicated in infections of the immunocompromised host; Enterobacteriaceae; most intestinal pathogens; and many gram-negative organisms commonly causing nosocomial infections. Haemophilus influenzae, Haemophilus ducreyi, Neisseria gonorrhoeae, Neisseria meningitidis, and Branhamella catarrhalis are highly susceptible to this class of drugs. Because of their ability to penetrate into phagocytes, fluoroquinolones have been tested against intracellular pathogens: Legionella species, Rickettsia conorii, Rickettsia rickettsii, and Brucella melitensis are very sensitive; Chlamydia trachomatis and the mycoplasmas are borderline; and some antimycobacterial activities deserve further investigation. Species that are generally resistant include Pseudomonas maltophilia, Pseudomonas cepacia, Pseudomonas pseudomallei, Alcaligenes species, Nocardia species, Bordetella bronchiseptica, and most anaerobes.
