Transposons play the most important role in building multi-drug resistant plasmids which can then be passed on to other bacteria.


A prophage can encode the synthesis of products that can make bacteria more pathogenic (lysogenic conversion).


PUT THIS STUFF IN YOUR FA....VERY IMPORTANT!!!!

I annotated in my FA from MBMRS that conjugation was the most important mechanism.

Transformation for the SHiN bacteria: strep pneum, Hem infl, Neisseria

Specialized lysogeny for the ABCDE: shigA like toxin, Botulism toxin, Cholera, Diphteria, Erythrogenic toxin strep.

Can someone add ...

And that is also correct....cuz plasmids get transferred via conjugation.

Transposon ----> Plasmid ----> Conjugation
