Bacterial cyanogenesis occurs in the cystic fibrosis lung.
The cystic fibrosis (CF) lung environment is poorly defined, but data suggest that bacteria may encounter reduced oxygen tensions and possibly an anaerobic environment. Pseudomonas aeruginosa produces the potent toxin cyanide under strictly microaerobic conditions. Evidence of bacterial cyanogenesis in the CF lung was investigated in the present study by measuring sputum cyanide concentrations....
متن کاملImpact of cigarette smoke exposure on host-bacterial pathogen interactions.
The human respiratory tract of individuals with normal lung function maintains a fine-tuned balance, being asymptomatically colonised by the normal microbiota in the upper airways and sterile in the lower tract. This equilibrium may be disrupted by the exposure to insults such as cigarette smoke. In the respiratory tract, the complex and noxious nature of inhaled cigarette smoke alters host-mic...
متن کاملHost–parasite–herbivore Interactions: Implications of Host Cyanogenesis
To examine the mediation of host–predator interaction by a parasite, we studied the three-level interactions among a host plant, a root hemiparasitic plant, and their common predator, a generalist snail herbivore. The host species, Trifolium repens, is able to synthesize cyanogenic glucosides that have a significant role in plant herbivore resistance. Some T. repens populations are polymorphic ...
متن کاملInferring biotic interactions from proxies.
Inferring biotic interactions from functional, phylogenetic and geographical proxies remains one great challenge in ecology. We propose a conceptual framework to infer the backbone of biotic interaction networks within regional species pools. First, interacting groups are identified to order links and remove forbidden interactions between species. Second, additional links are removed by examina...
متن کاملBiotic Interactions Influencing Shrub Establishment
BIOTIC INTERACTIONS INFLUENCING SHRUB ESTABLISHMENT ON AN ATLANTIC COAST BARRIER ISLAND. Elucidating mechanisms influencing the establishment of woody species is essential for understanding community dynamics and successional processes on barrier islands. The relative intensity of facilitation and inhibition of grasses on seedling establishment of two woody species common to Atlantic Coast barr...
