aPrairie dogs were confirmed positive on recovery of an isolate with characteristic
growth on cysteine heart agar with 9% sheep blood and positive testing of the isolate by direct fluorescent assay (DFA) or ISFtu2 polymerase chain reaction (PCR).
bPrairie dogs were considered presumptive positive if primary tissues tested positive by
DFA or PCR but no isolate was obtained.
cPrairie dogs were confirmed negative if all three diagnostic tests (culture, DFA, serologic testing) failed to detect any evidence of Francisella tularensis infection.
