Final answer:
The false statement about biofilm-related disease loci is that these diseases are exclusively respiratory. The correct answer is option b).
Step-by-step explanation:
The false statement about the loci of biofilm-related diseases is that biofilm-related diseases are exclusively respiratory. Biofilms are responsible for a variety of infections across different parts of the body and in association with various devices.
They are notorious for causing problems such as dental plaque, infections in patients with cystic fibrosis, and Legionnaires' disease. Biofilms also colonize medical implements like catheters and prostheses, potentially leading to infections at the site of medical implants.
Moreover, biofilms can be problematic in healthcare settings as they may grow on medical equipment such as hemodialysis machines or ventilators and can contribute significantly to infections acquired in hospitals, known as nosocomial infections. The difficulty of treating biofilm-related infections is well-recognized due to their resistance to antibiotics and host defense mechanisms.
