Spread of bacteria and fungi

bacteria have numerous modes of transportation. You are right there are spore forming bacteria, that undergo normal growth and form spores throughout their life cycles which can lay dormant for decades possibly. For instance the bacillis anthricas outbreak on an island in Britain there are spores from the outbreak that are still viable and this happen what 30 years ago i believe im not sure about the date. other modes of mobility  are from contact. you have countless amounts of bacteria on you as we speak and everywhere you go and everything you touch you pick up and deposit bacteria. other bacteria are motile which is different from mobile. mobile means it can move but motile means it can move under its own power example cocci are not motile but they can be mobile. motile bacterium can move via flagella or cillia. hope this helped

Due to their size, they can be carried by a multitude of vectors, including insects, your hands, saliva, etc.
