Selected antimicrobial essential oils to eradicate multi-drug resistant bacterial biofilms involved in human nosocomial infections.

Biofilms are the primary source of contamination linked to nosocomial infections by promoting bacterial resistance to antimicrobial agents, including disinfectants. Using essential oils, this study aims to inhibit and eradicate the biofilm of enterobacteria and staphylococci responsible for nosocomial infections at Guelma Hospital, northeastern Algeria. , and essential oils were evaluated against clinical strains of , , and .

Efficacy of endemic Algerian essential oils against single and mixed biofilms of Candida albicans and Candida glabrata.

Objectives: This study investigated the in vitro effect of Origanum glandulosum, Ammoides verticillata, and Saccocalyx satureioides essential oils against planktonic cells and biofilms formed by single and mixed species of Candida albicans and Candida glabrata oral isolates. The effect of the essential oils in combination with amphotericin B on planktonic cells was also studied.

Design: The antifungal susceptibility of planktonic cells was evaluated by disc diffusion and broth microdilution methods.
