Verified step by step guidance

Understand the role of Pattern Recognition Receptors (PRRs): PRRs are part of the innate immune system and recognize pathogen-associated molecular patterns (PAMPs) that are unique to microorganisms.

Identify molecules unique to bacteria: Peptidoglycan is a well-known bacterial PAMP, but the question asks for additional molecules.

Consider Lipopolysaccharide (LPS): LPS is a component of the outer membrane of Gram-negative bacteria and is recognized by PRRs, specifically TLR4.

Evaluate Flagellin proteins: Flagellin is a protein that makes up the bacterial flagella and is recognized by PRRs, specifically TLR5.

Analyze the other options: Fungal cell walls are not unique to bacteria, and tubulin proteins are found in eukaryotic cilia, not bacteria. Therefore, they are not recognized by PRRs as bacterial PAMPs.
