There are a number of schools offering a microbiology course completely online including the laboratory. Ocean County College is one of these schools (BIOL 232 Microbiology DL online).
Many of these schools use a LabPaq from Hands-On Labs, Inc. in Colorado. They use the lab kit with a microscope to actually culture harmless microbes to illustrate microbiological techniques.
Other schools offering these courses are CCCOnline and Mid State Technical College in Wisconsin. Microbiology 10-806-197 sec 24063.
So, you can take a fully accredited online microbiology course with the laboratory.
I hope this helps! --WiseProf
