Biofilm bacterial resistance
WebOct 1, 2024 · Bacterial cells within biofilms are more resistant to the presence of any stress conditions or host immune systems. Biofilms are considered biofouling in the context of man-made industrial surfaces, but biofilms have been implicated in bacterial chronic infections (Koo et al., 2024). Notably, many pathogenic bacteria use biofilms to survive … WebThese bacterial communities were differently spatially distributed in the two biofilms, depending on the chemical composition of each kind of biofilm. Consequently, the spatial distribution led to the development of specific phenotypic characteristics in the two biofilms (i.e., heavy metal and antibiotic resistance patterns, antagonistic ...
