Detection of Chlamydia pneumoniae

no antibodies to brucella when tested 9 months later is evidence against a common source of infection. Brucellosis in domestic animals has not been recorded in Sweden since the 1950s, and human brucellosis acquired in this country has not been reported since then. The possibility of coital transmission of bmcella has long been suggested, but only recently has brucellosis been isolated from human spamato~oa.~ We thus conclude that the woman was probably infected by her boyfriend, possibly by sexual intercourse during genital manifestation of the disease.
