These structures are implicated in otitis media and Legionnaire's disease, and genetic mutations leading to highly viscous respiratory mucous prevent cilia from clearing out these formations in cystic fibrosis.
These structures' proliferation may depend on transposon-mediated development of a specialized form of adhesin. The cidA gene, which codes for a holin protein, facilitates the formation of these structures, and the ica gene and mu phage are among the elements that can cause phase variation in them. Homoserine lactones function as chemotactic agents in a process called quorum sensing that leads to the formation of these structures in Pseudomonas aeruginosa. These structures are implicated in otitis media and Legionnaire's disease, and genetic mutations leading to highly viscous respiratory mucous prevent cilia from clearing out these formations in cystic fibrosis. These structures, which frequently form on artificial joints, develop when bacteria in a planktonic state randomly adhere to an existing layer of organic materials adsorbed to a surface. For 10 points, identify these microorganismal aggregates exemplified by dental plaque.
