Eagle Effect in Nonreplicating Persister Mycobacteria
We determined the microbicidal activities of antibacterials against nonreplicating Mycobacterium smegmatis grown in a starvation-based Loebel model for persistence. Whereas most drugs lost their activity, fluoroquinolones retained lethal potency. Dose-response characterizations showed a paradoxical more-drug-kills-less Eagle effect. Pretreatment of cultures with chloramphenicol blocked the leth...
متن کاملEffect of antiphage serum on the virulence of Corynebacterium diphtheriae.
There is little doubt that the toxigenicity of diphtheria cultures is associated with the lysogenic state. Blair (1924) noted that filtrates from toxigenic cultures lysed atoxic cultures of the diptheria bacillus but not the toxigenic cultures, but later investigators were able to isolate certain phages which could lyse toxigenic strains. We now know that, in general, lysogenic cultures are res...

متن کاملScreening for Corynebacterium diphtheriae.
A throat swab from a 9 year old girl with pharyngitis yielded a non-toxigenic strain of Corynebacterium diphtheriae var mitis and Streptococcus group G. C pseudodiphtheriticum was isolated from the throats of two of her four brothers. In each case the isolate was sent to the reference laboratory before full identification. The growth was found to be mixed for one brother; the other isolate bein...
