Evaluation of amlodipine against strains of spp. in planktonic cells, developing biofilms and mature biofilms.

To evaluate the antifungal activity of amlodipine against strains of spp. and to its possible mechanism of action. Broth microdilution tests were used to determine the minimum inhibitory concentration, while the synergistic activity was evaluated by calculating the fractional inhibitory concentration index.

Biosurfactant complexed with arginine has antibiofilm activity against methicillin-resistant .

The present study investigated the antimicrobial effectiveness of a rhamnolipid complexed with arginine (RLMIX_Arg) against planktonic cells and biofilms of methicillin-resistant (MRSA). Susceptibility testing was performed using the Clinical & Laboratory Standards Institute protocol: M07-A10, checkerboard test, biofilm in plates and catheters and flow cytometry were used. RLMIX_Arg has bactericidal and synergistic activity with oxacillin.

Synergistic effects of ketamine and azole derivatives on spp. resistance to fluconazole.

The emergence of spp. with resistance to antifungal molecules, mainly the azole class, is an increasing complication in hospitals around the globe. In the present research, we evaluated the synergistic effects of ketamine with two azole derivatives, itraconazole and fluconazole, on strains of spp.
