Antimicrobial susceptibility of intracellular Legionella pneumophila.
Minimum inhibitory concentrations, minimum bactericidal concentrations, and killing curve assays were measured after Legionella pneumophila was grown in human lung fibroblasts. Results of susceptibility testing of organisms grown intracellularly are compared with results for organisms grown by standard tube dilution methods.
متن کاملHigh-Throughput Intracellular Antimicrobial Susceptibility Testing of Legionella pneumophila.
Legionella pneumophila is a Gram-negative opportunistic human pathogen that causes a severe pneumonia known as Legionnaires' disease. Notably, in the human host, the organism is believed to replicate solely within an intracellular compartment, predominantly within pulmonary macrophages. Consequently, successful therapy is predicated on antimicrobials penetrating into this intracellular growth n...
متن کاملSusceptibility of Legionella pneumophila to twenty antimicrobial agents.
Thirty-three isolates of Legionella pneumophila, all except one of which were clinical isolates, were tested against 20 antimicrobial agents by using an agar dilution technique. Erythromycin, rifamp]in, and rosaramycin were the most active agents tested. Aminoglycosides, chloramphenicol, and cefoxitin also inhibited the organisms at low concentrations. Other agents, including moxalactam, cefope...
متن کاملNaip5 Affects Host Susceptibility to the Intracellular Pathogen Legionella pneumophila
BACKGROUND Legionella pneumophila is a gram-negative bacterial pathogen that is the cause of Legionnaires' Disease. Legionella produces disease because it can replicate inside a specialized compartment of host macrophages. Macrophages isolated from various inbred mice exhibit large differences in permissiveness for intracellular replication of Legionella. A locus affecting this host-resistance ...
