FcaGHV1 is a newly described gammaherpesvirus that widely infects domestic cats.
This study provides the first evidence of a host immune response against FcaGHV1.
Cat antibody responses were detected against multiple recombinant FcaGHV1 antigens.
Seroreactivity against FcaGHV1 ORF52 and ORF38 indicates 32% seroprevalence in USA.
Approximately half of FcaGHV1 seropositive cats have detectable genome using qPCR.
