There is a little problem with the pedantic poster (the commenter at ars)... Bacteria comes from 'bacteria' in greek, which means 'rod' or 'stick' (walking stick). The fact that some people neolatinized and fabricated a 'bacterium' means absolutely nothing. If you want to be pedantic, say 'bacterion' and 'bacteria', but then again you would probably write it 'bakterion'. Wikipedia is not the definitive source for a lot of things, least of all this.
