"Mister, usually written in its abbreviated form Mr. (US) or Mr (UK), is a commonly used English honorific for men under the rank of knighthood. The title 'Mr' derived from earlier forms of master, as the equivalent female titles Mrs, Miss, and Ms all derived from earlier forms of mistress. "

The most important question:

does every American abbreviation use a period "." at the end? 

In British English it depends on the last letter of the word! 

The same like in Polish (dr, mgr inż., lek. med., itp., itd., pon., sob., WF, WC, Sp. z o.o.) with exceptions (S.A. instead of SA) - Polish American abbreviation or initials?    :-) 

And what type is the word of the symbol of "first and last names" like below? 

Fanka Biedronki = FBD
