- Biofilms can form on medical implants within human tissues.
- Biofilms can form on food and food processing surfaces.
- Biofilms can exhibit antibiotic resistance.
Which of the statements given above are correct?
- A 1 and 2 only
- B 2 and 3 only
- C 1 and 3 only
- D 1, 2 and 3
Show Answer
The correct answer is D.
Biofilms can form on medical implants within human tissues:
- This statement is correct. Biofilms are a complex group of microbial cells that can adhere to the exopolysaccharide matrices available on the surface of various medical devices, such as intravascular catheters, urinary catheters, dental implants, breast implants, and orthopedic implants. They are responsible for the failure of devices such as catheters and ventilator.
Biofilms can form on food and food processing surfaces:
- This statement is correct. Biofilms can form on food and food processing surfaces. They affect product quality and safety of food, and bacterial adhesion onto surfaces of processing equipment in contact with foods is indicated by the formation of biofilms.
Biofilms can exhibit antibiotic resistance:
- This statement is correct. Bacteria living in a biofilm can exhibit a 10 to 1,000-fold increase in antibiotic resistance compared to similar bacteria living in a planktonic state. Many times bacteria form biofilms to resist the action of antibiotics.
