Abstract: The nematodes were found at a high percentage (66.7%) in the lung tissue by histopathological examination of beagle dogs imported from U. S. A. to Japan as laboratory animals. Although these infected dogs did not display abnormal respiratory signs, postmortem examination revealed the presence of adults and larvae of the lungworms in the alveolar spaces, and in many cases terminal and respiratory bronchioles with slight inflammatory reaction by adult worms and marked gronulomatous inflammation by larva. Degenerated larvae were also found in the liver and lymph nodes evoking a focal granulomatous reaction. Accordingly the dogs infected with these worms are unsuitable as laboratory animals, and the importations of these infected animals may result in prevalence of filaroidiasis in our country. These lungworms are readily distinguished fromFilaroides osleri (Osler, 1877) by the location in lung and by much smaller body size and spicules. These lungworms are most similar toF. milksiWhitlock, 1956, but can be distinguished by smaller size and slightly stouter spicuter spicules. They are identified asF. hirthiGeorgi and Anderson, 1975
