- Statement 1 is correct: Biofilms are a significant cause of infections on medical implants like catheters, prosthetic joints, and heart valves, as bacteria can attach to the surface and form a protective layer. - Statement 2 is correct: Biofilms readily form on surfaces in food processing environments and on the food itself, leading to spoogenic (spoilage- causing) and pathogenic contamination. - Statement 3 is correct: Biofilms provide microorganisms with increased resistance to antibiotics, disinfectants, and the host immune system. This is due to the protective matrix, altered growth rates of cells within the biofilm, and genetic exchange.
