Opportunistic fungi are tracked by epidemiologists. are normal microbiota for many individuals. have the same geographical distribution as pathogenic fungi. have special proteins for colonizing the body. always have two physiological and structural forms.

The correct answer is- are normal microbiota for many individuals

Explanation:

Opportunistic organisms are those organisms that normally do not cause infection because their infection and growth are resisted by the host immune system and the presence of normal microflora of the body.

So opportunistic fungi can be present with normal microbiota in many individual without causing any infection but when the host immune system falls and the normal microbiota gets disturbed these opportunist fungi gets space and environment to grow and cause infection.

Some of the opportunistic fungi are- Candida, Aspergillus, Cryptococcus, etc. Therefore the correct answer is- are normal microbiota for many individuals.
