Antibiotic tolerance poses medically important challenges. It is largely responsible for the inability to eradicate bacterial infections with antibiotic treatment. Persister cells are highly enriched in biofilms, and this makes biofilm-related diseases difficult to treat. Examples are chronic infections of implanted medical devices such as catheters and artificial joints, urinary tract infections, middle ear infections and fatal lung disease . WebThe biofilm persistence in the environment and in the host is due to the high microbial cell density which also includes ‘persister cells,’ characterized by a dormancy state. The EPS …
