Gram Positive Coccus

Bacterial Pathogen Pronunciation Station

Gram negative rod

It is difficult for students not familiar with the names of  bacteria to pronounce them. This sound station contains links to sound files of these bacteria. There are other ways to pronounce these bacteria. This is the way I pronounce them when teaching our medical students at ATSU/KCOM*. You say Ser-rah-tee-a and I say Ser-ra-shia. However, if my pronunciation is incorrect I would like to know. Email me ( and tell me how you pronounce the following bacterial names. The volume of some of the sound files maybe low. Please turn up your speakers and try the sound file again if you don't hear anything.
