Abstract

Texas quail populations have declined over the past few decades. While habitat loss has been identified as the primary cause, it has been speculated that pathogens may also play a role in this decline. To help address this, we collected scaled quail, Callipepla squamata, Gambel's quail, Callipepla gambelii, and Montezuma quail, Cyrtonyx montezumae, from across the Trans-Pecos ecoregion of Texas via hunter-harvest. Quail samples were then necropsied to document pathogens not previously recorded in the host species. Pathogens were submitted to the Texas A&M University Veterinary Medicine Diagnostic Lab (TVMDL), where parasite identification and histopathological analyses were conducted. From this, we identified several parasites that had never been documented in the quails of the Trans-Pecos ecoregion of Texas. This study was the first to document Mycobacterium sp. and Sarcocystis sp. in scaled quail, Subulura sp. and Physaloptera sp. in Montezuma quail, and Oxyspirura petrowi and Aulonocephalus pennula in a Texas Gambel's quail.
