Background The disinfectants polyhexamethylene biguanide (PHMB) and 1-bromo-3-chloro-5,5-dimethylimidazolidine-2,4-dione (BCDMH) each have limitations. So far, their combined usage has not been examined. In this study, the fungicidal activity of combined disinfectant using PHMB and BCDMH, named PB, against Candida albicans was evaluated. Methods Suspension quantitative fungicidal test and via...
To combat infection and antimicrobial resistance, it is helpful to elucidate drug mechanism(s) of action. Here we examined how the widely used antimicrobial polyhexamethylene biguanide (PHMB) kills bacteria selectively over host cells. Contrary to the accepted model of microbial membrane disruption by PHMB, we observed cell entry into a range of bacterial species, and treated bacteria displayed...
Acanthamoeba keratitis (AK) is a sight-threating infection of the cornea that mostly affects contact lens wearers. Until now, AK treatment remains very difficult due to the existence of a highly resistant cyst stage in the life cycle of Acanthamoeba which is extremely resistant to most of the available anti-amoebic compounds. Moreover, current treatment of AK is usually based in the combination...
Biofilms are a major problem in hard-to-heal wounds. Moreover, they composed of different species and often tolerant to antimicrobial agents. At the same time, interspecific synergy and/or competition occurs when some bacterial clash. For this reason, tolerance two dual-species wound biofilm models Pseudomonas aeruginosa Staphylococcus aureus or Enterococcus faecium against antimicrobials dress...
