Verified step by step guidance1
Step 1: Understand the types of microorganisms targeted by each antimicrobial agent. Penicillin G is primarily effective against certain bacteria, especially Gram-positive bacteria.
Step 2: Recognize that Isoniazid is an antibiotic specifically used to treat Mycobacterium tuberculosis, the bacterium that causes tuberculosis, and is not effective against fungi.
Step 3: Know that Ciprofloxacin is a broad-spectrum antibiotic effective against various bacteria but does not target fungal infections.
Step 4: Identify Amphotericin B as an antifungal agent that binds to ergosterol in fungal cell membranes, disrupting their integrity and leading to fungal cell death.
Step 5: Conclude that among the options, Amphotericin B is the recommended antimicrobial agent for treating fungal infections due to its specific antifungal activity.
