ABSTRACT The fitness cost of an antibiotic resistance gene (ARG) can differ across host strains, creating refuges that allow the maintenance of an ARG in the absence of direct selection for its resistance phenotype.Despite the importance of such ARG-host interactions for predicting ARG dynamics, the basis of ARG fitness costs and their variability

In the North of Brazil (Pará and Amazonas states) the leaves of the plant Talinum triangulare (popular: cariru) replace spinach as food.From a phytochemical point of view, they are rich in compounds of the group of pheophytins.These substances, related to chlorophyll, have photophysical properties that give them potential application in photodynam
