The two main mechanisms responsible for thrombus formation in mammals are the activation and aggregation of platelets and the generation of fibrin through the coagulation cascade. The aim of this work was to study the anticoagulant potential of excretory\/secretory antigens from <jats:italic>D. immitis<\/jats:italic> adult worms (DiES) on the coagulation cascade of the host. Anticoagulant and inhibition assays respectively showed that DiES partially alter the coagulation cascade of the host and reduce the activity of the coagulation factor Xa, a key enzyme in the coagulation process. In addition, a <jats:italic>D. immitis<\/jats:italic> protein was identified by its similarity to the homologous serpin 6 from <jats:italic>Brugia malayi<\/jats:italic> as a possible candidate to form an inhibitory complex with FXa by sodium dodecyl sulfate polyacrylamide gel electrophoresis and mass spectrometry. These results indicate that <jats:italic>D. immitis<\/jats:italic> could use the anticoagulant properties of its excretory\/secretory antigens to control the formation of blood clots in its immediate intravascular habitat as a survival mechanism.<\/jats:p>","DOI":"10.1017\/s0031182020000104","type":"journal-article","created":{"date-parts":[[2020,1,29]],"date-time":"2020-01-29T07:20:18Z","timestamp":1580282418000},"page":"559-565","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":13,"title":["<i>Dirofilaria
