Extract of sample "Viruses, Fungi and Parasites"

Cytomegalovirus-immunocompromised host (CMV) is a type of virus that belongs to the Herpes viruses. The virus causes diseases in different parts of human beings bodies such as the Cytomegalovirus retinitis disease. The CMV infections occur in individuals whose immune system has been weakened by AIDS, organ transplant, chemotherapy, bone marrow transplants or medicines that are capable of suppressing the immune system. A CMV infection affects different parts of the body such as the esophagus, the stomach, the intestines, eye and the lungs.

Once the CMV enters a person’s body, it remains alive and dominant within the host’s body. This virus can only cause diseases only when the host immune system is suppressed because of diseases or medication (University of Maryland Medical Center, 2011). The Candida spp are the opportunistic type of fungal pathogens that resides within the human body. The fungal resides without people’s knowledge and causes various infections such as eye infections. When the body immune system is weakened, the fungal quickly attacks the various body parts.

This fungal species have the ability to distinguish between a healthy host and unhealthy host and alter its physiology so as to tack the body (Boston, 2012).
