^aBacterial isolation from organs or tissues obtained from experimentally infected animals at 60 days postinfection. GLN, gastrosplenic lymph nodes; ILN, inguinal lymph nodes; SLN, submandibular lymph nodes; PLN, prepectoral lymph nodes; NEG, negative isolation; POS, positive isolation; ND, not done (no sample available); UNC, uncountable CFU. For blood samples, 5 ml was inoculated directly into Ruiz-Castañeda bottles.
