Morphology

mycobacterium = bacterium (semi-transparent) = myco + bacterium

The core word is clearly 'bacterium' (so learners will recognise it as a bacterium), but the combining form 'myco-' (meaning 'fungus' or 'fungus-like') is a technical biological element unlikely to be known by a B1 learner.

Etymology

The word mycobacterium is made of myco- meaning 'fungus' and bacterium meaning 'small rod'. Early scientists thought these bacteria looked like fungi and were long rods, so the name points to their fungus-like look and rod shape, which is why mycobacterium refers to that group of bacteria that can cause diseases like tuberculosis.
