The Distribution of Group E Streptococcus Among Lymph Nodes of Experimentally Infected Swine

摘要

Lymph nodes, spleens, and tonsils from swine infected experimentally with Group E >Streptococcus (GES, the causative agent of jowl abscess) were examined grossly and bacteriologically. Forty-two abscessed lymph nodes were seen among 14 infected swine. Pure cultures of GES were recovered from each abscess. Approximately half of 112 pools of grossly normal lymph nodes yielded GES as did half of 14 tonsils and 14 spleens. All GES recovered were morphologically and serologically identical to the strain used to create the experimental infection.
