I Wonder What A Concurrent Pseudomonas + Proteus Infection Would Smell LIke


 I am definitely in the camp that believes Pseudomonas smells like grapes and Proteus like chocolate. I have certainly heard other creative ideas for what bacteria smell like. E. coli always had a distinctive smell to me as well. It wasn't necessarily a bad or putrid smell, just... unique. 

I will never forget the smell of Clostridium perfringens and Citrobacter though. 

The coolest scent would be that of Actinobacteria such as Streptomyces. They create geosmin which is well associated with the earthy odor in 'dirt' and is responsible for the "smell of rain". Humans are particularly sensitive to Geosmin and can smell it down to 5 parts per TRILLION.
