Chemical composition of Kunth essential oil and evaluation of its antimicrobial and modulatory effects on antibiotic resistance, antibiofilm, and cell dimorphism inhibitory activities.

Essential oils extracted from many plant species have different biological activities, among which microbial activity stands out. Species of the genus have antimicrobial potential against different species of bacteria and fungi. In this sense, the present study aimed to determine the chemical composition of the essential oil from the leaves of (EOPG), as well as to investigate their antimicrobial activity and their modulatory effect on the Norfloxacin resistance in the SA1199B strain overproducer of the NorA efflux pump.

Modulation of the Drug Resistance by Mart. Extract, Ethyl Acetate Fraction and Morelloflavone/Volkensiflavone (Biflavonoids) in Strains Overexpressing Efflux Pump Genes.

Background: Microbial resistance to antibiotics is a global public health problem, which requires urgent attention. Platonia insignis is a native species from the eastern Brazilian Amazon, used in the treatment of burns and wounds.

Objectives: To evaluate the antimicrobial activity of the hydroalcoholic extract of P.

Synergic effect of simvastatin in combination with amphotericin B against environmental strains of Cryptococcus neoformans from northeastern Brazil: a prospective experimental study.

Background: Statins are used as cholesterol-lowering drugs and may also have direct antimicrobial effects.

Objective: To evaluate synergic interactions between simvastatin and both amphotericin B and fluconazole, against environmental strains of Cryptococcus neoformans isolated from captive birds' droppings.

Designand Setting: Experimental study conducted at Federal University of Piauí, Parnaíba, in collaboration with Federal University of Triângulo Mineiro, Uberaba, Brazil.
