Abstract

Ticks are blood-feeding arachnids that are vectors of several important human and animal pathogens. Little is known about single-stranded DNA (ssDNA) viruses that are associated with these ectoparasites. As part of a pilot study to identify ssDNA viruses present in ticks, female American dog ticks (Dermacentor variabilis) and blacklegged ticks (Ixodes scapularis) were collected in eastern Pennsylvania (USA), and the extracted viral DNA was analyzed using viral metagenomics approaches. Three genomoviruses were recovered from pooled samples of D. variabilis (n = 2) and I. scapularis (n = 1): two belonging to the genus Gemycircularvirus, sharing < 63% pairwise identity with other members within the genus; and the third belonging to the genus Gemykolovirus, sharing < 70% pairwise identity to other gemykoloviruses. Furthermore, a genome of an anellovirus belonging to the sharing 62–65% nucleotide identity with torque teno canis viruses (genus Thetatorquevirus) was also recovered from a D. variabilis pooled sample.
