Which of the following fungi can infect non-immunocompromised individuals?

1. Aspergillus

2. Bastomyces

3. Penicillium

4. Trichoderma

The correct answer is: Bastomyces

Bastomyces is the correct choice because it is a pathogenic fungus known to cause a disease called blastomycosis, which can infect individuals regardless of their immunocompromised status. This fungus is found in environments such as damp soil and decaying organic matter, and inhalation of spores can lead to infection in healthy individuals. In contrast, Aspergillus, while commonly present in the environment, tends to primarily affect individuals with weakened immune systems. Most healthy individuals can tolerate exposure to Aspergillus without developing serious health problems. Similarly, Penicillium and Trichoderma are generally less pathogenic and are more commonly associated with allergies or mild infections rather than systemic disease in non-immunocompromised people. Therefore, while Aspergillus, Penicillium, and Trichoderma can be a concern for certain populations, Bastomyces stands out as capable of causing infection in healthy individuals as well.
