L. Casei Imunitass, L. Casei Defensis

Actimel, also from Danone, is a drinkable yoghurt with “a specific probiotic (a living ferment bringing health benefits), stemming from the research carried out by Danone, the Lactobacillus casei Defensis.” Defensis is a mixture of “defence”, alluding to the potential benefits to the immune system, and “-sis”, a latinization to suggest a scientific derivation. L. casei Defensis is also known as L. casei Imunitass. Imunitass follows the same pattern of the word root suggesting health benefits, in this case helping the immune system, with a “scientific” (although not latinate) ending. Names for the bacteria therefore depend on the country being marketed to, and may also change over time to emphasise different health claims for the products.
