PATHOLOGY CAUSED BY THE TREMATODEIN FREE-RANGE WILD BLUE-CROWNED MOTMOTS () IN CENTRAL AMERICA.

Abstract

Wildlife conservation law in Costa Rica protects common motmots (), limiting the specimens available to study their health and biology. This report describes the finding of the trematodein the trachea, air sacs, lung, and celomatic cavity of two free-living. Histiocytic air sacculitis and pleuritis with granulomas containing trematodes, as well as adhesions between the air sacs and pericardium, were observed. In addition, histiocytic pneumonia, air sacculitis, celomitis, ulcerative tracheitis, and necrotizing histiocytic hepatitis showing intralesional parasites were detected. Eggs with morphology compatible withwere found in the feces of both birds. To our knowledge, this is the first report ofin motmots of Central America. As may be seen in the second case, severe respiratory compromise was possibly affecting the bird's capacity to fly. Longitudinal studies of the host, parasite, and environment are necessary to understand the implication forinfection to the health and survival of the common motmot.
