Question
Biofilms are often formed on artificial surfaces in the human body. During medical procedures, when
artificial joints, intravenous catheters, urinary catheters are placed and injections are made,
commensals/mutualists may be introduced into new sites in the body and there they may form
biofilms.
Which statement below is NOT a reason to explain why such bacteria living in biofilms are so
difficult to eliminate?
O layers of biofilm prevent phagocytes from killing bacteria
O layers of biofilm acts a a diffusion barrier against antibiotics
O biofilm stimulates bacteria to grow continually in the log/exponential phase of growth
O layers of biofilm acts a a diffusion barrier against antibodies/immunoglobulins
O bacteria often in stationary phase of growth
