Perhaps that will help.
Also, note that the term bacteria is already a plural term, the singular being bacterium.

Actually I think one can use 'bacterias' to refer to different 'types' at one time i.e. generas etc.

Much in the same way as fish and fishes.

Maybe, but i don't think so.
You see, most of the nouns I know that behave like that have the plural from the same group identical to the singular.
fruit(one apple) - fruit (many apples) - fruits(apples and grapes)
The same with fish

Again, I say that i don't know for sure. But this is my opinion.

To come back to the original topic. depends who you are. if you are a researcher or a student with a profesional adress you can just look on medline if someone has that and kindly ask them for a sample. If you are just anyone, I doubt that anybody will send you something, and you will have to pay (and yes certified bacterial strains are expensive, but considering he QC/QA work involved, this is not without reason...).

what does QC/QA stand for?

Quality Control/Assessment (i think)

Almost, A is for assurance.

It is not easy to prove that the strain you have is actually a perfect copy of the original. So it needs a lot of testing and also regular testing of the stored products (and eventually renewing stores if needed) to insure constant quality. Hence the prices. ATCC is a not for profit organization, as well as the Pasteur Institute. So all the Quality controls drives the prices up.
Transport is not cheap either. You would not want a leak of bacteria in your mail, would you ;)
