An Antidote for Opportunistic Parasitism

Opportunistic infections (OIs) are illnesses that, while mild or asymptomatic in healthy individuals, develop into fatalities in those with compromised immune systems. Defence systems like humeral or cell-mediated are present in the human body. A compromised immune system creates the ideal environment for opportunistic infections to grow over the host system and spread disease. These pathogens are frequently transmitted by contact with contaminated food, water, or bodily fluids.

The immune systems can become compromised for a variety of reasons, including illnesses (such HIV infection or cancer), medical treatments (like organ transplants), aging, chemotherapy, and others. HIV/AIDS is the most difficult of these diseases. Depending on the patient's CD4+ T cell levels, different infections can induce OIs. However, the most frequent infections that cause illness and mortality in people with HIV/AIDS are parasites. Immune responses to parasites can cause infections of the blood, brain, digestive system, respiratory tract, and other organs. Cryptosporidium parvum, Isospora belli and Cyclospora cayetanensis are the three parasite species that are most frequently responsible for enteric OIs.

Opportunistic parasitism is a symbiotic relationship between opportunistic parasites and immunosuppressed hosts. This has the potential to be lethal and frequently increases the patients' odds of dying. To achieve proper management, early detection and treatment must be implemented. People with HIV will live better lives if they receive the proper initial care in new cases and maintenance therapy in chronic cases.
