Biofilm microbes can withstand higher antibiotic doses

Infectious diseases kill 15 million people worldwide each year and about 65% of these diseases are associated with biofilms, especially in chronic infections. Due to protection by the biofilm matrix and differences in cell activity and genetics, bacteria in some biofilms can survive at least 20 to 50 times higher concentration of antibiotics compared to their planktonic counterparts. Biofilm research is important to develop new treatment strategies, such as the disruption of biofilm formation by inhibiting bacterial communication.
