1
Q
Symbiosis
A
e. g. bioluminexcent V. fischeri and Bobtail Squid
- Selective colonisation
2
Q
Parisitism
A
Relationship where one organism benefits and the other suffers
3
Q
Mutualism
A
Mutually beneficial relationship between organisms
4
Q
Commensalism
A
One organism benefits, the other neither benefits nor suffers
5
Q
Biofilms
A
- Attachment - suppression of motility factors, induction of adhesion factors
- Growth - intercellular interaction, quorum sensing
Biofilm maturation - induced extracellular polysaccharides (matrix) synthesis, phenotypic diversity - Detachment - Quorum sensing, induction of disassembly factors

A
AHL = Acyl-homoserine lactone
