I know its a late reply, but I came across this a year later, looking for the same thing, and decided to try my hand at it in case in another year someone else comes looking for the same thing.
My answer is that it depends on the context. (Like always)
If you are spreading bacteria uniformly over agar: to spread
If you are streaking to get isolated colonies (en rayas): to streak
If you are adding bacteria to a liquid culture: to inoculate
If you are putting eukaryotic cells into tissue culture: to seed
If you are infecting a tissue culture or organism: to infect or to inoculate
