Bacteriologists love to smell their cultures. There is one famous dangerous genus though and that is Brucella: no specific smell, but a good chance to get infected with a potentially lethal bacteraemia. Brucellosis is known for its potential of occupational laboratory infection. Brucella is a gram-negative bacterium which can be isolated from blood cultures or abcesses. It grows on blood and chocolate agar as small white colonies. Don't ever sniff from such colonies which you expect to be Haemophilus or another gramnegative.
