The question is incomplete. The complete question is as follows:
A treatment for bacterial infections from the early 20th century has made a comeback-the use of bacterial viruses to eliminate bacterial infections. Which explanation most accurately describes this mechanism of action behind this treatment?
A. A wide variety of bacteria cause a large percentage of human infections, producing much sickness and death.
B. Viruses can infect bacteria, transferring pathogenic genes. The viral genes can then be suppressed, causing the bacteria to not replicate viruses.
C.The attachment structures on the virus and the receptors on the host cells make for exquisite specificity of viruses for particular bacterial species.
D. Antibiotic resistance in humans is on the increase, so using a different kind of therapy is more beneficial.
Answer:
Option (C) and (D).
Explanation:
The pathogens are the organisms that can cause harm to the living organisms. Various strategies and drugs has been research to kill these pathogens
The viruses can also be used to treat the bacterial and viral infections. This methodology was used in the early 20th century but has come back because the antibiotics that are given makes the bacteria resistance against the particular treatment. The virus and bacteria has some specific and unique receptors that provide specificity of the virus against the bacteria and can be used for the treatment.
Thus, the correct answer is option (C) and (D).
Vaccines produce a primary response in which memory cells exist developed that respond rapidly in a second exposure.
<h3>Can a child vaccinated for chicken pox get it?</h3>
Some individuals who are vaccinated against chickenpox may still contract the disease. However, the symptoms exist usually milder with fewer or no blisters (they may include just red spots) and mild or no fever. You should not be vaccinated against chickenpox if you: Exist moderately to severely ill at the period of vaccination.
Vaccines produce a primary response in which memory cells exist developed that respond rapidly in a second exposure. Vaccines work by teaching the body's immune system to determine and protect against harmful viruses or bacteria before acquiring an infection and decrease the chance of acquiring certain infectious diseases.
A vaccine exists in a biological preparation that furnishes actively developed immunity to a particular infectious disease. A vaccine generally includes an agent that resembles a disease-causing microorganism and exists often created from weakened or killed conditions of the microbe, its toxins, or one of its surface proteins.
