Initiation:
N bacteria signed with 3 properties a) with/without F-Plasmid b)infected by virus or not c)hold antibody or not.(Property b and c cannot both be positive at the same time.)


I've once read a paper of Redfield(1993) "Genes for Breakfast: The Have-Your-Cake and-Eat-lt-Too of Bacterial Transformation". Though it's an old publication, I still find the idea very inspiring. Well, considering bacteria living in a gene-pool with abandoned DNA strands, each bacterium can randomly "eat" free DNA strands, and use them as nutrition or for DNA repairing or even gene improvement. But the DNA strands were abandoned for a reason. Some of them can be virulent.(!!!) Besides bacteria can exchange DNA with each other, of course. We can define a population size of bacteria, amount of free DNA strands in gene-pool, percentage of virulent DNA and their virulence (impact on the bacteria fitness). We certainly can also consider the bacteria as a metapopulation.("A metapopulation consists of a group of spatially separated populations of the same species which interact at some level." - says wikipedia.org) The question to be answered will be "in which situation the bacterial population will become extinct in the end".
Interaction rules:
Only bacteria with F-Plasmid can transfer their positive properties(a and b or c) to another bacterium.
Infected bacteria can be cured by receiving antibodies. And bacteria holding antibodies cannot be infected.

Dynamics of the fraction of infectious, immune bacteria and bacteria holding F-Plasmids. (Which kind of attractor can we expect?)

Attention: Next meeting Friday(the first week)
at what time?

Initiation: N bacteria signed with 3 properties a) with/without F-Plasmid b)infected by virus or not c)hold antibody or not.(Property b and c cannot both be positive at the same time.)

Interaction rules: Only bacteria with F-Plasmid can transfer their positive properties(a and b or c) to another bacterium. Infected bacteria can be cured by receiving antibodies. And bacteria holding antibodies cannot be infected.

Observation: Dynamics of the fraction of infectious, immune bacteria and bacteria holding F-Plasmids. (Which kind of attractor can we expect?)
