Answer

Brucella can gain entry into the human body through breaks in the skin, mucous membranes, conjunctivae, and respiratory and gastrointestinal (GI) tracts. Sexual transmission has not been convincingly documented. Ingestion usually occurs by way of unpasteurized milk; meat products often have a low bacterial load. In the United States, percutaneous needlestick exposure, conjunctival exposure through eye splash, and inhalation are the most common routes of entry.
