Mortalidad invernal de ciervos de los pantanos (Blastocerus dichotomus) en humedales del noreste de Argentina
Abstract
One of the most abundant populations of marsh deer (Blastocerus dichotomus) occurs in Iberá Reserve in Corrientes, where events of winter mortality are frequent. We registered 34 dead and 9 sick marsh deer in the study area between May and August 2007. We examined 2 clinically sick and 1 dead deer and found high gastrointestinal nematode burdens (3180 -19 200 eggs per gram in fresh feces) including the finding of Haemonchus contortus in marsh deer for the first time in Argentina. Other putative infectious agents were excluded. High parasite burden and the occurrence of H. contortus were the most likely causes of the 2007 winter mortality, in coincidence with unusual adverse climatic conditions and apparent reduced availability of pastures. © SAREM, 2013.
