*In addition to neutrophils and lymphocytes shown in the table, leukocyte counts included eosinophils, basophils, and monocytes; however, none had >2 counts for any individual bat. Health was assessed by palpation of pectoral muscle mass. Viral-classified reads were compared with a viral sequencing database. ID, identification; NA, not applicable.
