  • Opportunistic Diseases in HIV Infection post dedicated to describe the traits of an opportunistic microorganism with proper examples.

Opportunistic Diseases in HIV Infection

  • In the broad realm of biological sciences, an opportunist can be described as an organism that can live a long time through various sources. When favorable conditions are created, the organism uses the chance to flourish. If the attention is directed towards microbiology, the scientists refer to organisms that behave as “opportunistic” microorganisms in this manner. 
  • Microorganisms are microorganisms that could be one cell, a cell in a cluster, or multicellular. Microorganisms vary in their diversity and include fungi, bacteria, algae, protozoa, and algae. 
  • Opportunistic microorganisms tend to be non-pathogenic microorganisms, which can be pathogens in certain situations. They remain dormant for long periods until the host’s immune system is shut down, and they then take the chance to strike.

  • Patients suffering from the Human Immunodeficiency Virus (HIV) are especially vulnerable to opportunistic infections. HIV could be transformed to Acquired immune deficiency syndrome (AIDS), which destroys helper T cells (specifically CD4+ T cells). 
  • If the CD4+ T cells are below a threshold and cell-mediated immunity decreases. If immunity is destroyed, opportunistic microorganisms can get into the AIDS patient and not be eliminated by immune systems. These pathogens are easily accessible and thrive while the human body slowly declines.
  • One instance of an opportunity-based microorganism would be Haemophilus decreyi. The organism can infect its victim through a damaged epidermis or skin. Also, in the absence of an open wound that is sexually transmitted, the disease could not utilize our body as a host. It makes the most of the chance to infect lymphocytes, macrophages, and granulocytes at the moment when it enters the site of the broken skin.

Summary

  • Microorganisms are microscopic organisms that can be one cell, a cell in a cluster, or multicellular. Microorganisms can be very diverse, including fungi, bacteria, algae, protozoa, and algae.
  • Opportunistic microorganisms tend to be non-pathogenic microorganisms which are pathogens in some circumstances. They are dormant for long periods until the patient’s immune system is weakened, and they use the opportunity to strike.
  • Haemophilus ducreyi is a microorganism that affects its victim through the epidermis or skin that has been damaged. Without an open wound, the sexually transmitted illness could not use humans as a host.
