the ability of some microbes, such as trypanosoma or giardia to alter their surface molecules and evade destruction by the hosts antibodies is called the ability of some microbes, such as trypanosoma or giardia to alter their surface molecules and evade destruction by the hosts antibodies is called cytopathic effect. lysogenic conversion. virulence. cytocidal effect. antigenic variation.

The ability of some microbes, such as Trypanosoma or giardia to alter their surface molecules and evade destruction by the host's antibodies is called antigenic variation. Thus, the correct option for this question is E.

How do pathogens evade detection by the immune system?

Pathogens like Trypanosoma, evade detection by the immune system by the fact that they change the surface antigens frequently and thus prevent the immune system from tracking them.

Antigenic variation may be defined as a type of mechanism through which an infectious agent such as a bacterium, virus, and protozoan alters the proteins or carbohydrates on its surface and thus avoids a host immune response, making it one of the mechanisms of antigenic escape.

Therefore, antigenic variation determines the ability of some microbes, such as Trypanosoma or giardia to alter their surface molecules and evade destruction by the host's antibodies. Thus, the correct option for this question is E.
