There have been no reports of this worm being recovered since the report of Faust and Tang in 1934.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>GEOGRAPHIC LOCATION:</b></span><span style="font-size: medium;"> Foochow, Fukien Province, China.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>LOCATION IN HOST:</b></span><span style="font-size: medium;"> Middle ear of the cat. All other species of Mammonogamus appear to be located within the trachea and larynx; thus, the location within the middle ear is surprizing.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>PARASITE IDENTIFICATION:</b></span><span style="font-size: medium;"> The males are orange red, 3.3 to 8.1 mm long, with delicate, subequal spicules. The females are blood red, 14 to 30 mm long; the vulva is 43% to 46% gbbeghind the anterior of the worm.. The adults are found consistently with the bursa of the male surrounding the vulva of the female; giving the worms a “Y-shaped” appearance. The eggs are 48 µm by 88 µm, with a thick, transparent sculptured shell that is in the 4 to 8 celled morula stage when laid. </span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>LIFE CYCLE: </b></span><span style="font-size: medium;">Very little is known about the biology of these parasites. The eggs apparently pass down the eustachian tubes into the pharynx, are swallowed, and pass out in the feces. </span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>CLINICAL PRESENTATION AND PATHOGENESIS: </b></span><span style="font-size: medium;">These parasites were not found attached to the wall of the middle ear; however, the mucosa was hemorrhagic. The typanic membranse of the cats were not injured.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>TREATMENT: </b></span><span style="font-size: medium;">Not known.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>EPIZOOTIOLOGY:</b></span><span style="font-size: medium;"> Not known.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>HAZARDS TO OTHER ANIMALS:</b></span><span style="font-size: medium;"> Not known.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>HAZARD TO HUMANS: </b></span><span style="font-size: medium;">Not known.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>CONTROL/PREVENTION:</b></span><span style="font-size: medium;"> Not known.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>REFERENCES:</b></span></p> <p align="JUSTIFY"><span style="font-size: medium;">Buckley JJC. 1934.
