Immatures were identified using a RFLP assay, with * indicating sequence confirmation. Site and month where the host was collected are included for each host. For mammals hosting adults, co-feeding ticks collected from the same host are reported, including Dermacentor variabilis (DV), Amblyomma americanum (AA), Ixodes scapularis (IS), and Dermacentor albipictus (DA). The monthly and annual infestation rate (IR), or percentage of hosts checked infested with AM, are included for each host species hosting adults. Co-feeding ticks and IR are not reported for rodent hosts, because of challenges associated with identifying immature engorged ticks.
The actual number of ticks from this cat is unknown; this A. maculatum tick may have been co-feeding with A. americanum larvae or I. scapularis adult ticks that were received by the ODU Tick Research Team from one veterinary clinic on the same day
