Which one of the following organisms is a fungus?

Result
Your answer: —  Â·  Correct: D
Explanation

Based on microbiological classification, Aspergillus is a genus of fungi, specifically a hyaline filamentous fungus or mold [t2][t6]. It is characterized by conidiophores and is known for producing mycotoxins in food products [t3][t6]. In contrast, the other options belong to the bacterial kingdom. Staphylococcus is a genus of Gram-positive bacteria often associated with food poisoning and skin infections [t3][t7]. Salmonella is a genus of rod-shaped Gram-negative bacteria responsible for diseases like typhoid and common foodborne illnesses [t1][t3]. Clostridium is a genus of anaerobic, spore-forming bacteria, including species like C. botulinum and C. perfringens, which are highly heat-resistant and pathogenic [t3][t7]. Therefore, while Staphylococcus, Salmonella, and Clostridium are bacteria, Aspergillus is the only organism listed that is a fungus [t2][t3].
