This is caused by various species of the Brucella bacterium. Brucellosis is found worldwide and is transmitted to humans through direct contact with infected animals. Major reservoirs include goats and sheep (B. melitensis), swine (B. suis), cattle (B. abortus), and dogs (B. canis). Outcomes associated with infection during pregnancy are not well known and transmission to the fetus is speculated to occur through the placenta. Whether infection leads to fetal death is controversial. Manifestations of neonatal brucellosis include low birth weight, fever, failure to thrive, jaundice, and hepatosplenomegaly. Antibiotic treatment during pregnancy may prevent abortion and premature delivery (57).
