Morphology

mycobacterium + leprae

The phrase is a taxonomic binomial: 'Mycobacterium' signals a bacterial genus and the epithet 'leprae' refers to leprosy, so together they denote the Mycobacterium species that causes leprosy. This is inferable if a learner recognises the biological naming pattern and the root 'lepra/leprae', but that requires domain-specific knowledge beyond typical B1 vocabulary, so the transparency is partial.

Etymology

Mycobacterium leprae gets its name from old words: myco- (because the tiny bacteria, seen under a microscope, looked a little like a fungus) and leprae (from a word meaning 'scaly', a common sign of the disease). So the name points to a small germ that causes 'leprosy', which helps you remember what it is.
