Hello. You did not enter the text to which these questions refer, which makes it impossible for them to be answered. However, I will try to help you in the best possible way.
It is only possible to answer your questions in a specific way by reading the experiment, however, I can inform you that formites are objects that allow the colonization and growth of microorganisms that can be major causes of diseases. Among these microorganisms are bacteria, fungi and viruses of the most varied species. Among these microorganisms, both fungi and non-demanding bacteria can grow in a nutrient agar culture medium. This is because this is a very simple culture medium where bacteria that do not need specific nutrients can grow and where most fungi can grow too. However, it is impossible for viruses to grow in this type of culture medium or in any culture medium, since viruses only develop inside a host's organism. Bacteria known as fastidious would also not grow in this type of culture medium, since they only grow with the presence of very specific nutrients.
Viral antigens like EBV are usually recognized by T cells involving an antigen fragment present within class I MHC to the T cell receptor.
Ebstein Barr Virus
The Epstein-Barr virus is a human herpes virus with unusual biological characteristics.
- It lives in practically every human person in a dormant condition in resting memory B lymphocytes
- It is also a strong transforming virus in vitro for B cells and is linked to numerous significant lymphomas, including Burkitt's, Hodgkin's disease, and immunoblastic lymphoma.
With the exception of the memory compartment, each stage of the cycle has been shown to be possibly controlled by the immune response.
Epstein-Barr virus (EBV), commonly known as human herpes virus 4, is a double-stranded DNA herpes virus that is extensively spread. It is the cause of infectious mononucleosis.
- EBV is most usually transmitted by body fluids, particularly saliva. EBV, on the other hand, can transmit by blood and sperm during sexual intercourse, blood transfusions, and organ transplants.
EBV can be transferred by utilizing materials that have recently been used by an infected individual, such as a toothbrush or a drinking glass.
- The virus is likely to survive on an object for at least as long as it is wet.
- When you initially get infected with EBV (primary EBV infection), you might spread the virus for weeks or even months before you notice any symptoms.
- Once the virus has entered your body, it remains dormant.
Hence, the correct answer is option A
