bacterio-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly.

Etymology: < bacteri- (in bacterium n.) + -o- connective.

Categories »

Forming terms (chiefly nouns and adjectives) to do with bacteria, as bacteriocidal adj., bacteriophage n., bacteriorhodopsin n.Where the second element begins with a vowel (as in bacteraemia n., bacteriuria n.), the word can be regarded as directly < bacterium n.
