Bertalan Meskó (@Berci) has compiled a list of microbiology blogs that you may find useful: Microbiology in the Blogosphere.
Envious, I decided to make my own list of microbiology blogs. After checking my Google Reader, I came up with a collection of 20 great blogs. I know there are many more out there, so please feel free to add a comment and suggest any microbiology blogs that may be missing from my list.
So, here they come, in strict alphabetical order:
