ELISA, Enzyme‐linked immunosorbent assay; IFA, indirect immunofluorescent assay; PCR, polymerase chain reaction.
a
The 2 E. canis positive results were detected in samples taken from the same 2 dogs.
b
1 of the 3 positive B. vogeli results was from the same dog PCR positive for B. vogeli on initial testing of an acute sample.
c
Total number of dogs testing positive for at least 1 agent.
