Question

Which of the following is considered an opportunistic pathogen?
A) Toxoplasma gondii
B) Trichomoniasis vaginalis
C) Candida albicans
D) Plasmodium vivax

Accepted Answer

Opportunistic pathogens are organisms that usually do not cause disease but can do so under certain opportunistic conditions, such as a weakened immune system. Candida albicans is a common opportunistic fungal pathogen that can cause infections such as thrush and systemic candidiasis. Toxoplasma gondii, Plasmodium vivax, and Trichomoniasis vaginalis are not typically considered opportunistic pathogens.
