Tell me, what is the most interesting thing to you about those fields?
Well, my almost aesthetic affection for such fields may seem odd, but things like bacteria and viruses exemplify what is truly beautiful about nature. Viruses are deceptively simple, at essence being DNA or DNA wrapped in a protein coat (capsid), and yet..they can completely manipulate organisms many times more complex. The same goes for bacteria; they are the oldest kingdom of creatures on Earth (kingdom Monera) and still reign today as the most plentiful, and their descendants are even within us as our mitochondria (it's called endosymbiosis, when one organism has a symbiotic relationship via living within it a similar relationship is thought to be with plants' corresponding energy source, the chloroplast).
When it comes to microbes I am most fascinated with the great diversity of metabolism as well as the evolutionary relationhips between the various groups.
Oh, and the term "Monera" isn't used anymore. Now days life in classified into 3 "domains," the Bacteria (eubacteria), the Archaea (archaebacteria), and the Eucarya (eukaryotes).
