What is a biofilm?
|
communities of microorganisms attached to a solid surface; the surface can either be nonliving or living tissue.
|
|
|
Co-biofilms of ______and _____are associated with serious lung infections in patients with ______
|
Pseudomonas and Burkholderia are associated with serious lung infections in patients with cystic fibrosis
|
|
|
Associated with serious lung infections in patients with cystic fibrosis.
|
Co-biofilms of Pseudomonas and Burkholderia
|
|
|
The sessile phenotype results from attachment and usually develops into a ________biofilm that has unique characteristics, making it similar in many ways to__________
|
multispecies biofilm that has unique characteristics, making it similar in many ways to hydrated polymers
|
|
|

|
sessile phenotype
|
|
|
________,______analogous to bacterial spores,are present in all biofilms and bacterial populations.
|
Persister cells.
Essential metabolically inert microorganisms. |
|
|
Persister cells.
Essential metabolically inert microorganisms. |
are present in all biofilms and bacterial populations.
|
|
|
Are hypothesized to have disabled programmed cell death, or apoptosis
|
Persister cells
|
|
|
These cells have the greatest potential for maintenance of the gene pool and resistance to environmental stress, including antimicrobial agents
|
Persister cells
|
|
|
How do biofilm protect bacteria.
(3ways) |
-Phagocytic cells are generally unable to penetrate the biofilm
-PMNs will degranulate and cause damage to nearby host tissue -may hide microbial agents, preventing an immune response on blocking interaction with antibody |
-Barrier
-PMN's -Immune |
