Nomenclature in Europe and Former USSR
In parts of Europe, the "O" in ABO blood type is substituted with "0" (zero), signifying the lack of A or B antigen. In the former USSR blood types are referenced using numbers and Roman numerals instead of letters. This is Janský's original classification of blood types. It designates the blood types of humans as I, II, III, and IV, which are elsewhere designated, respectively, as O, A, B, and AB. The designation A and B with reference to blood groups was proposed by Ludwik Hirszfeld.

Famous quotes containing the word europe:
“I thought ten thousand swords must have leaped from their scabbards to avenge even a look that threatened her with insult. But the age of chivalry is gone. That of sophisters, economists and calculators has succeeded; and the glory of Europe is extinguished forever.”
—Edmund Burke (1729–1797)
