Lung tissue from 52 bobcats, Lynx rufus, from Alabama, Kansas, New Mexico, Oklahoma, and Virginia were examined for the presence of lung-inhabiting parasites by gross inspection and histological examination. Parasites identified included Metathelazia californica, Troglostrongylus wilsoni, Vogeloides felis, and Paragonimus kellicotti. No parasite was discovered in bobcat lungs from New Mexico or Virginia. Distributions of M. californica and V. felis infections have been extended to include bobcats from Alabama, Kansas, and Oklahoma. The distribution of P. kellicotti has been extended to include bobcats from Alabama and Oklahoma, whereas that of T. wilsoni now includes bobcats from Alabama.
