Answer

Although various potential intermediate hosts have harbored brucellosis in the extra-Mediterranean world, dairy cattle infected with B abortus have been particularly important hosts in North America. The infection is often symptomatic in cattle. Outbreaks of epizootic bovine abortion due to B abortus should alert health care providers to the possibility of human brucellosis. Some cases in humans in North America have been traced to pork from hogs infected with B suis. In Scandinavia and Alaska, reindeer are an important source of brucellosis.
