and (Spirurida: Onchocercidae) detected in wild carnivores from Texas, United States.

and (Spirurida: Onchocercidae) are epidemiologically important filarial nematodes detected in wild carnivores sympatric to domestic animals and humans. In this study we surveyed for species among previous studies archived blood samples (n = 202) of wild carnivores sourced across Texas between the years of 2014-2016 and 2020 to 2023. In total, 117 coyotes (), 67 raccoons (), 12 gray foxes (), five bobcats (), and one striped skunk () were tested through the amplification of the partial cytochrome oxidase c subunit 1 () gene followed by sequencing. was detected in 11.39% (95% CI = 7.71-16.51) of the samples (21 coyotes and two raccoons), while was detected in a single bobcat. sequences had 99.85%-100% (99.92% ± 0.08) similarity with other sequences in GenBank. The sequence of from the bobcat was 100% similar to the single sequence available in GenBank. Data from this study reinforce the role of coyotes as a wild reservoir for and suggest that raccoons may also play a role in the epidemiology of this parasite. This study additionally provides molecular data on , an understudied filarioid of felids.
