Excerpt:
Results-Sensitivity and specificity of the in-clinic ELISA for detection of
heartworm antigen (99.2% and 100%, respectively), antibodies against B
burgdorferi (98.8% and 100%, respectively), and antibodies against E canis
(96.2% and 100%, respectively) were similar to results for a similar
commercial ELISA. In samples obtained from dogs in the northeast and upper
Midwest of the United States, sensitivity and specificity of the in-clinic
ELISA for antibodies against Anaplasma spp were 99.1% and 100%,
respectively, compared with results for an immunofluorescence assay. Samples
from 2 dogs experimentally infected with the NY18 strain of A
phagocytophilum were tested by use of the in-clinic ELISA, and antibodies
against A phagocytophilum were detected by 8 days after inoculation.
Antibodies against Anaplasma platys in experimentally infected dogs
cross-reacted with the A phagocytophilum analyte. Coinfections were
identified in several of the canine serum samples.
Conclusions and Clinical Relevance-
The commercially available in-clinic ELISA could be used by veterinarians to
screen dogs for heartworm infection and for exposure to tick-borne
pathogens.
