A new drug blocks the adhesins on the surface of a bacterial pathogen. What would likely be the major effect of this drug?

A. It will inhibit the growth and reproduction of this pathogen.
B. It will prevent the formation of the glycocalyx in this pathogen.
C. It will kill the pathogen.
D. It will prevent infection by this pathogen.

Answer :

Final answer:

A drug that blocks the adhesins on the surface of a bacterial pathogen will primarily prevent the pathogen from causing an infection. This is due to the role of adhesins in helping pathogens attach to host cells. The drug does not necessarily kill the bacteria or inhibit its growth.

Explanation:

The new drug is likely to have the effect of preventing infection by the bacterial pathogen (option d). Adhesins, which are either proteins or carbohydrates, can be found on the surface of certain pathogens and interact with specific receptors on host cells, thus enabling the pathogen to attach to the host. They are present on appendages such as the fimbriae and flagella of bacteria. Blocking these adhesins would therefore prevent the pathogen from attaching to host cells, subsequently inhibiting infection. This does not necessarily kill the pathogen or inhibit its growth and reproduction, and it does not directly affect the formation of the glycocalyx.

Preventing a pathogen from attaching to host cells is a key strategy in infection control. It is important to note that the term 'adhesin' is not limited to bacteria, but is also used to refer to similar structures on other types of pathogens such as protozoa and viruses.
