Table 1 Recovery of Brucella suis from tissues obtained at necropsy from domestic and feral swine after conjunctival challenge with B. suis strain 3B vaccinated with 10¹⁰ colony-forming units of B. suis strain 353-1

Treatment Groups	Control	Parenteral vaccinates	Oral vaccinates
Feral swine
Major organsa	9/9	0/5*	0/5*
Lymph nodesb	9/9	0/5*	2/5*
Domestic swine

Lymph nodesb	6/7	3/6	3/5

Notes:

a Major organs are defined as the lung, liver, spleen, and kidney.

b Lymph nodes are defined as bronchial, hepatic, mandibular, mesenteric, parotid, popliteal, prescapular, and retropharyngeal.
