Question

It was diagnosed by a specialist that the immune mechanism of the body of a patient has been suppressed. Name the disease the patient has been suffering from and the microbe responsible for it. Which part of the immune system does it affect and in what manner?

Answer 1

The patient is suffering from Acquired Immuno Deficiency Syndrome (AIDS). Causal organism is Human Immunodeficiency Virus (HIV). 

HIV infects helper T-cells. HIV enters helper T-cells where it replicates and produces progeny viruses. The progenies liberated by lysis of host T-cells attack other helper Tcells. Repeated attacks result in progressive decrease in the number of T-cells and thus reducing immunity.
