Cryptococcus is a fungal disease that can cause meningitis in people with AIDS and other immunocompromised people. It is an opportunistic infection.
Opportunistic infection
A non pathogenic organism cause infection in host when the host's immune system is down.It is called as opportunistic pathogen.That infection is known as opportunistic infection.Example for opportunistic pathogen:Candida albicans, Mycobacterium avium-intracellulare, cytomegalovirus (CMV) ---- Pathogen to HIV positive persons.
Kleb pneumo is a bacteria. It is opportunistic and may be the cause of a bacterial infection. A bacterial culture would be sufficient to detect it and depending where it is, it may or may not be significant.
If the infestation is not treated, the patient may develop complications that include headache, fever, and bacterial infection with scarring.

HIV infection will bring in the dreaded syndrome called as AIDS. It may take up to eight years to develop the AIDS. If you are on proper therapy, the duration to develop the AIDS is prolonged to many years. In case of AIDS, you immunity is suppressed. You get infections by opportunistic infections.
There are many different opportunistic infections and many different ways to treat them.

Kapose's Sarcoma (KS) is an opportunistic disease that occurs in people with weakened immune systems. HIV (Human Immunodeficiency Virus) weakens the immune system severely enough for patients to develop KS. HIV is not the only cause of weakened immune systems. Other conditions, such as Lupus, may also cause an individual to develop an opportunistic infection.
These infections are called "opportunistic infections." They are called opportunistic because a weakened immune system is necessary for them to cause serious infection.

The ones who might already have an infection or have a low immune level.
An opportunistic infection (OI) is an infection that occurs only when the host's defense systems (ie, the immune system) are weakened. The common characteristic of all agents that cause opportunistic infections is that they rarely affect individuals with healthy immune systems. For example, the disease AIDS (acquired immunodeficiency syndrome) is a classic cause of immune system depression and is associated with many opportunistic infections, including toxoplasmosis, pneumocystis pneumonia (PCP), and others.
