Bacteria subsisting on antibiotics.
Antibiotics are a crucial line of defense against bacterial infections. Nevertheless, several antibiotics are natural products of microorganisms that have as yet poorly appreciated ecological roles in the wider environment. We isolated hundreds of soil bacteria with the capacity to grow on antibiotics as a sole carbon source. Of 18 antibiotics tested, representing eight major classes of natural...
متن کاملAntibiotics from predatory bacteria
Bacteria, which prey on other microorganisms, are commonly found in the environment. While some of these organisms act as solitary hunters, others band together in large consortia before they attack their prey. Anecdotal reports suggest that bacteria practicing such a wolfpack strategy utilize antibiotics as predatory weapons. Consistent with this hypothesis, genome sequencing revealed that the...
متن کاملBacteria, antibiotics and COPD.
Bacterial infection is one of several important causes of exacerbations of chronic obstructive pulmonary disease (COPD) that may coexist. COPD is a heterogeneous condition and the incidence of bacterial infection is not uniform; mucus hypersecretion may be an important risk factor. The bacteriology of infections varies depending on the severity of the underlying airway disease. There is now a m...
متن کاملScreening for antibiotics active against intracellular bacteria.
A large number of useful antibiotics have been discovered since the isolation of tyrothricin in 1939, yet as time passes and as the number of known antibiotics increases, their rediscovery becomes more and more fre(uent. Improvements in screening techniques are therefore indicated to eliminate undesired antibiotics with a minimum of labor. New techniques should also attempt to recognize biologi...
متن کاملNew antibiotics for antibiotic-resistant bacteria
The need for new antibiotics to effectively treat antibiotic-resistant infections remains unfulfilled. Despite the well-publicised concern over this issue, only two novel antibiotic classes have been introduced in the past 20 years alongside several new agents of existing classes. Accordingly, the current antibiotic armoury remains inadequate to meet the challenges posed by resistance today. Mo...
