Oestrosis in Asiatic ibex (Capra sibirica): a case report and molecular characterization of larvae

Abstract Three third-instar Oestrus larvae were found in the frontal sinus of an adult female Asiatic ibex ( Capra sibirica ) in the Tian Shan mountain range, Kyrgyzstan. The larvae were identified as Oestrus ovis based on morphology and after sequencing and analyzing a fragment of the cytochrome oxidase I (COI) gene. In light of this identification and the fact that Asiatic ibex and livestock are sympatric in many areas in Central Asia, we discuss the risks of interspecific parasite spillover.
