Consider the following statements: Which of the statements given above are correct?

  1. 1.

    Biofilms can form on medical implants within human tissues.

  2. 2.

    Biofilms can form on food and food processing surfaces.

  3. 3.

    Biofilms can exhibit antibiotic resistance.

Options

a

1 and 2 only

b

2 and 3 only

c

1 and 3 only

d

1, 2 and 3

Answer

Explanation

All three statements are correct.

Biofilms are structured communities of microorganisms encased in a self-produced matrix. They adhere to wet surfaces, including medical implants (like catheters) and food processing machinery. Because of their dense matrix, microbes inside biofilms are highly protected and inherently exhibit severe antibiotic resistance.

Biofilms act as microbial fortresses, allowing bacteria to cling to surfaces and resist chemical and antibiotic attacks.

Answer: (d).
