The full gastrointestinal (GI) tract was homogenized, and three aliquots were incubated for small mammals or birds. In some cases, separate liver samples were collected (e.g., starling). Specimens were collected either as pooled gastrointestinal tract (ileum, mesenteric lymph node [MLN], liver, and feces not collected separately [na]) or as the individual tissues and feces (gastrointestinal tract not pooled [na]).
Two lymph node samples were incubated, and isolates were obtained from both.
