Answer:
The fewer number of T cells a person has, the more chances to be affected by an opportunistic infection. When the number of T cells reaches 200 cells/µl, the person is at risk of being infected by other infections.
Explanation:
The whole immune system of a person who is infected with HIV infection seems to be severely affected. When the person is not treated or the disease is in a very advanced stage, the depletion of the T- cells turns to be very sharped, especially CD4+ T cells. At this point, the immune system can not resist the attack of other microorganisms. The <em>lower is the number of CD4+ T Cells, the higher possibility the person has to be attacked by opportunistic infections. </em>
Classically, it has been suggested that opportunistic infections appear after the CD4 + T lymphocytes reach very low levels, such as 200 cells/µl. The number of circulating T cells can be used as an indicator and a measure of global "immune competence", and the previously mentioned amount of CD4 + T cells is an accepted universal reference used to predict the risk of having one of these opportunistic infections.
It is an organic substance.
Answer:
The correct answer is c. Bacteremia
Explanation:
Nosocomial infection is a hospital-acquired infection. Intravenous catheterization is majorly used in hospitals for therapeutic purposes like drug administration, blood sampling, etc.
These catheters are one of the major causes of nosocomial bacteremia in patients. Bacteremia is the condition in which bacteria is present in the blood.
So these catheter can be contaminated with bacteria which came from a patient and when they are used in another patient without proper sterilization they can transfer these bacteria to other patients blood which then cause nosocomial bacteremia.
Ventilation is the act of moving/pushing air into and out of the lungs.
d. enzymes increase the rate of chemical reaction by providing activation energy to the substrate
