What ecosystem are you talking about ?
Organ system is the answer according to me if it is one word question
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.
The most common transfusion reaction, especially in patients lacking either IgA especially serum IgA, is the development of potentially severe hypersensitivity reactions or anaphylaxis. The most probable culprit is the presence of IgA in the transfused blood, because since the individual lacks IgA, then the IgA in the transfused blood is considered a foreign body triggering an allergic response.
