A living microbe with reduced virulence that is used for vaccination is considered:<\/p>\n\n\n\n
a. A toxoid
b. Dormant
c. Virulent
d. Attenuated
e. Denatured<\/p>\n\n\n\n
The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n The correct answer is d. Attenuated<\/strong>.<\/p>\n\n\n\n An attenuated microbe refers to a microorganism, such as a virus or bacterium, that has been modified to reduce its virulence (ability to cause disease). This form of the microbe is still capable of inducing an immune response but is not harmful in the same way as the wild-type pathogen. Attenuation is commonly used in the development of live vaccines.<\/p>\n\n\n\n Attenuated vaccines contain live microorganisms that have been weakened through processes such as genetic manipulation, growth under abnormal conditions, or exposure to certain chemicals or heat. These weakened microbes can replicate in the body, but they do not cause the severe disease associated with the fully virulent strain. Instead, they stimulate the immune system to recognize and attack the pathogen, providing immunity without causing illness. Because of this ability to mimic a natural infection without the risk of a full-blown disease, attenuated vaccines are highly effective in building immunity.<\/p>\n\n\n\n One well-known example of an attenuated vaccine is the measles, mumps, and rubella (MMR) vaccine. This vaccine contains live, attenuated versions of the measles, mumps, and rubella viruses. Other examples include the oral polio vaccine (OPV) and the yellow fever vaccine.<\/p>\n\n\n\n In contrast to attenuated vaccines, toxoid<\/strong> vaccines, such as the tetanus and diphtheria vaccines, contain inactivated bacterial toxins that have been modified to prevent their harmful effects while still triggering an immune response. Virulent<\/strong> microbes are capable of causing disease in their normal form, and dormant<\/strong> refers to a state where the microbe is inactive or in a resting phase, not typically used for vaccination. Denatured<\/strong> refers to the structural changes that occur in proteins, which can render them non-functional and are unrelated to the use of microbes in vaccines. Therefore, attenuated<\/strong> is the most accurate term for a microorganism used in vaccination that has reduced virulence but can still provoke an immune response.<\/p>\n","protected":false},"excerpt":{"rendered":" A living microbe with reduced virulence that is used for vaccination is considered: a.
