Chronic infection was defined as the continued, intermittent recovery of organisms while on antibiotics, or immediate return of infectious symptoms after cessation of antibiotic therapy, with no period of clinical quiescence while off of antibiotic therapy.
As the scientists recount in an article in Nature, the algal bloom extended to 100 meters (328 feet) deep in the ocean, showing that even in very deep layers, intermittent light allows the organisms to flourish.
Despite the intermittent presence of other organisms, every peritoneal culture over a one-month period, nine in total, grew the same difficult-to-identify yeast.
The excretion of organisms in milk is intermittent [ 21].
Much work has been done investigating tidepool organisms' strategies to withstand intermittent hypoxia (e.g. Richards, 2011), but investigations distinguishing the effects of hypercapnia are lacking.
Candida albicans is widely distributed throughout the human population as both a commensal organism and as an intermittent pathogen.
Aquatic organisms are often subject to intermittent exposure to pollutants in real ecosystems.
As the major etiological agent of human tooth decay, Streptococcus mutans is particularly well-adapted to growth in oral biofilms, where the intermittent nature of human feeding presents the organisms with a "feast or famine" existence [1].
In biology and medicine, hormesis is defined as an adaptive response of cells and organisms to a moderate (usually intermittent) stress".
The novelty of the pulsed or intermittent quality of the dosing regimen for the organism is essential to set endogenous amplification responses into motion; continuous or ad lib exposures do not mobilize sensitized states [ 187, 205].
There is good reason to believe that early organisms may have begun to adapt to intermittent low levels or "whiffs" of O2, generated either biologically or abiologically prior to the Great Oxidation Event, even though the atmosphere remained largely anoxic.
