A preliminary note on the susceptibility of goats to Malta fever.

Zammit discovered that contaminated goat milk was the vector for transmission to humans of the Malta fever bacterium, Brucellosis melitensis. At the time goat milk was a primary source of milk in Malta and other parts of the world. Zammit's campaign to Pasteurize goat milk led to eradication of the disease in Malta and other parts of the world.
