Celebrated annually on 17 September, International Microorganism Day is aimed at raising awareness of the importance of microorganisms within our daily lives. Dutch scientist, Antonie van Leeuwenhoek, made the discovery of microorganisms on 17 September 1674 – being the first to observe and describe microorganisms using a microscope. The day now provides a platform for microbe enthusiasts to commemorate the discovery of microorganisms.

(Yes, I’m still a bacteriologist at heart.)
