The mechanisms that lead to phenotypic antibacterial tolerance in bacteria remain poorly understood. We investigate whether changes in NaCl concentration toward physiologically higher values affect antibacterial efficacy ...

Bacterial persistence is a transient, nonheritable physiological state that provides tolerance to bactericidal antibiotics. The stringent response, toxin-antitoxin modules, and stochastic processes, among other mechanisms, ...

The traditional artisanal Minas cheese is characterized by the use of raw milk and endogenous starter culture in its elaboration. The typical flavor of these cheeses is obtained by transformations performed mainly by lactic ...

Antibacterial activity of 17 strains of lactobacilli was tested against 10 strains of H. pylori. The inhibition observed was related to the acid production and the low pH attained. No relationship between CagA phenotype ...

The origin of a terrestrial flora in the Ordovician required adaptation to novel biotic and abiotic stressors. Oil bodies, a synapomorphy of liverworts, accumulate secondary metabolites, but their function and development ...

Nos últimos anos, a Organização Mundial da Saúde vem alertando que a era pós-antibióticos é uma ameaça cada vez mais real. Além da resistência individual das células bacterianas, essas podem se tornar ainda mais tolerantes ...
