Final answer:
Biofilms on pacemakers can lead to UTIs, infective endocarditis, and are resistant to antibiotics.
Explanation:
Biofilms are microbial communities that are difficult to destroy and can form on medical devices like pacemakers. These biofilms can lead to various infections, including urinary tract infections (UTIs), due to their resistance to antibiotics and ability to attach to surfaces. Additionally, biofilms on pacemakers can result in infective endocarditis, a serious infection of the heart's inner lining or the heart valves.
