It was originally described as </span></span><span style="color: #000000;"><span style="font-size: medium;"><i>"Euparadistomum</i></span></span><span style="color: #000000;"><span style="font-size: medium;"> sp." (Talbot, 1969) but then recognized as a new species. Other species of </span></span><span style="color: #000000;"><span style="font-size: medium;"><i>Euparadistomum</i></span></span><span style="color: #000000;"><span style="font-size: medium;"> have been described from cats, and a number of species have been described from reptiles. It may be that reptiles are the typical hosts of this group of trematode parasites.</span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;"><b>GEOGRAPHIC DISTRIBUTION:</b></span></span><span style="color: #000000;"><span style="font-size: medium;"> New Guinea.</span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;"><b>LOCATION IN HOST: </b></span></span><span style="color: #000000;"><span style="font-size: medium;"> Gall bladder, none in the bile ducts.</span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;"><b>PARASITE IDENTIFICATION:</b></span></span><span style="color: #000000;"><span style="font-size: medium;"> This fluke is quite discoid in appearance with a color that is pinkish grey when alive. The diameter of the body is about 5 mm. The ventral sucker is centrally placed and has a diameter of 1 to 1.3 mm; the oral sucker is slightly smaller than the ventral sucker. The testes are anterior to the ventral sucker, and each is about one-fourth the diameter of the ventral sucker. The small ovary is at the posterior margin of the ventral sucker. The genital opening is between the oral and ventral suckers. The eggs are operculate, with yellow to brown eggshells, measuring 35 to 52 µm in length by 18 to 26 µm in width.</span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;"><b>LIFE CYCLE: </b></span></span><span style="color: #000000;"><span style="font-size: medium;"> Not known. It is suspected that the intermediate host is an arthropod.</span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;"><b>CLINICAL PRESENTATION AND PATHOGENESIS:</b></span></span><span style="color: #000000;"><span style="font-size: medium;"> Signs in infected cats have not been described if they are present. </span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;"><b>TREATMENT:</b></span></span><span style="color: #000000;"><span style="font-size: medium;"> Probably praziquantel, but not reported.</span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;"><b>EPIZOOTIOLOGY:</b></span></span><span style="color: #000000;"><span style="font-size: medium;"> It is not known how cats become infected. It is most likely that they are accidentally ingesting some arthropod that supports the development of the metacercarial stage. Of course, it may be as in </span></span><span style="color: #000000;"><span style="font-size: medium;"><i>Platynosomum</i></span></span><span style="color: #000000;"><span style="font-size: medium;"> (below) in which there is a reptile as the third intermediate host.</span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;"><b>HAZARD TO OTHER ANIMALS:</b></span></span><span style="color: #000000;"><span style="font-size: medium;"> None known. </span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;"><b>HAZARD TO HUMANS:</b></span></span><span style="color: #000000;"><span style="font-size: medium;"> There have been no records as to the infection of human beings with this parasite. If a person were to ingest the arthropod host, they could perhaps develop an infection.</span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;"><b>CONTROL/PREVENTION:</b></span></span><span style="color: #000000;"><span style="font-size: medium;"> This cannot be done until the life cycle has been elucidated.</span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;"><b>REFERENCES:</b></span></span></p> <p align="JUSTIFY"><span style="color: #000000;"><span style="font-size: medium;">Talbot N. 1969.
