Answer

Most human cases of brucellosis in the United States are due to B melitensis. The B abortus and B suis species that have accounted for most brucellosis in North America are less likely to engender clinical disease in humans than B melitensis is. When disease develops in North Americans, it often does so with greater latency to onset and milder manifestations.
