Morphology

mycobacteria = bacteria (semi-transparent) = myco + bacteria

The head 'bacteria' makes it clear this is a kind of bacteria, but the technical combining form 'myco-' is specialized and may be unfamiliar to a B1 learner.

Etymology

Mycobacteria combines myco- meaning 'fungus', as in 'mushroom', and bacteria meaning 'tiny rods' or 'germs'. So the name shows these are rod-shaped germs that once looked like fungus, which helps explain why some of them cause diseases like tuberculosis and leprosy.
