Fatal aerosacculitis and pneumonia associated with Eucoleus sp. (nematoda: capillaridae) in the lungs of a Peregrine Falcon (Falco peregrinus).
ABSTRACT A Peregrine Falcon (Falco peregrinus) died of verminous and bacterial pneumonia and aerosacculitis associated with capillarid nematodes of the genus Eucoleus. This represents an aberrant location for these helminths in avian hosts. Although positive identification was not possible, the worms resembled Eucoleus aerophilus, a species not reported previously from birds.
