The indirect fluorescent antibody test was used to examine 109 samples of equine sera randomly selected from serum pools. Results were compared with titers obtained by the microagglutination (MA) test. A high correlation (r = 0.89) was found between titers measured by the 2 tests. Blood samples were obtained serially from a total of 156 horses at a research farm and the sera were tested against Legionella pneumophila serogroups 1 through 4 using the MA test; 29 horses (19%) seroconverted to at least 1 serogroup of L pneumophila. The indirect fluorescent antibody test substantiated the results obtained by the MA test. Seroconversions in horses provided additional evidence that horses become naturally exposed to legionellae.
