International Medical Foundation of Japan. Fukuoka, Japan) recognizes 28 species with 21 in Asia, 2 in Africa, and 5 from the Americas. All of these trematodes are parasites of the lungs as adults. Also, all are probably capable of developing within the cat. However, not all have been reported from the cat with only twelve of the species being reported from this host. Typically cats become infected with these trematodes by the ingestion of an infected crustacean. The adults of Paragonimus are large, robust trematodes with thick bodies that are covered with spines. Typically they are found in cysts within the lungs that may contain anywhere from one to ten adult flukes. These trematodes are capable of causing serious disease in the infected host. Again, as with the Opisthorchids, some of these trematodes, especially Paragonimus westermani causes serious disease in people, and there is a great deal of literature on the subject in texts of human parasitology. An excellent concise summary of the different species causing disease in humans that is based on first-hand knowledge is found in Miyazaki’s text </span></span><span style="color: #000000;"><span style="font-size: medium;"><span style="text-decoration: underline;">Helminthic Zoonoses</span></span></span><span style="color: #000000;"><span style="font-size: medium;">.</span></span></p> &nbsp; &nbsp; <p align="CENTER"><span style="color: #000000;"><b>TREMATODE PARASITES OF THE LUNGS</b></span></p> &nbsp; <span style="color: #000000;">TROGLOTREMATIDAE</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>westermani</i></span><span style="color: #000000;"> (Kerbert, 1878) Braun, 1899</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>pulmonalis</i></span><span style="color: #000000;"> (Baelz, 1880) Miyazaki, 1978</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>miyazakii</i></span><span style="color: #000000;"> Kamo, Nishida, Hatsushika, and Tomimura, 1961</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>heterotremus</i></span><span style="color: #000000;"> Chen and Hsia, 1964</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>siamensis</i></span><span style="color: #000000;"> Miyazaki and Wykoff, 1965</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>skrjabini</i></span><span style="color: #000000;"> Chen, 1964</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>ohirai</i></span><span style="color: #000000;"> Miyazaki, 1939</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>kellicotti</i></span><span style="color: #000000;"> Ward, 1908</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>mexicanus</i></span><span style="color: #000000;"> Miyazaki and Ishii, 1968</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>inca</i></span><span style="color: #000000;"> Miyazaki, Mazabel, Grados, and Uyema, 1975</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>africanus</i></span><span style="color: #000000;"> Voelker and Vogel, 1965</span> <span style="color: #000000;"><i>Paragonimus</i></span><span style="color: #000000;"><i>uterobilateralis</i></span><span style="color: #000000;"> Volker and Vogel, 1965</span> &nbsp; &nbsp; &nbsp; &nbsp;
