is an emerging zoonotic vector-borne parasite infecting dogs and other mammals in the United States. In this study we evaluated shelter dogs in one northeastern and one southeastern county in Oklahoma for prevalence of exposure to . Dogs were tested for antibodies against using the Chagas STAT PAK assay and for in circulation by PCR. In addition, dogs were tested for evidence of infection with other vector-borne organisms using the SNAP 4Dx Plus Test and PCR. Overall, 26 of 197 (13.2%) shelter dogs had detectable antibodies against and 3 of 189 (1.6%) dogs were PCR positive. In addition, we found that 42 of 197 (21.3%) shelter dogs had evidence of exposure to or were infected with at least one vector-borne agent other than based on serology and/or PCR; 9 of 42 (21.4%) of these dogs were also positive for antibodies. Other infections identified in dogs included , , sp. (Coco), , , , , and . This study serves to boost state-wide veterinary and public health awareness of and other vector-borne pathogens infecting shelter dogs in Oklahoma. Results indicate the need for more comprehensive screening of shelter dogs in Oklahoma for exposure to vector-borne agents to enhance surveillance and to identify dogs in need of additional specific veterinary care.
是一种新兴的人畜共患寄生虫，感染美国的狗和其他哺乳动物。在这项研究中，我们评估了俄克拉荷马州东北部和东南部的一个县的收容所狗，以确定它们接触 的情况。使用 Chagas STAT PAK 检测试剂盒检测狗体内针对 的抗体，使用 PCR 检测循环中的 。此外，使用 SNAP 4Dx Plus 检测试剂盒和 PCR 检测其他媒介传播的病原体的感染证据。总的来说，197 只收容所狗中有 26 只（13.2%）检测到针对 的抗体，189 只狗中有 3 只（1.6%）PCR 阳性。此外，我们发现，根据血清学和/或 PCR，197 只收容所狗中有 42 只（21.3%）有接触或感染除 以外的至少一种媒介传播剂的证据；其中 9 只（21.4%）狗的 抗体也呈阳性。在狗中还发现了其他感染，包括 、 、 sp.（Coco）、 、 、 、 和 。这项研究有助于提高俄克拉荷马州兽医和公共卫生部门对 及其他感染收容所狗的媒介传播病原体的认识。结果表明，需要更全面地对俄克拉荷马州的收容所狗进行媒介传播剂接触情况的筛查，以加强监测并确定需要额外特定兽医护理的狗。
