For a period of time, it was considered to be a synonym of </span><span style="font-size: medium;"><i>Rictularia</i></span><span style="font-size: medium;"><i>affinis</i></span><span style="font-size: medium;"> Jägerskiöld, 1909, and has also appeared under the name of </span><span style="font-size: medium;"><i>Pterygodermatites</i></span><span style="font-size: medium;"><i>affinis</i></span><span style="font-size: medium;">. In 1996, Barus et al. reexamined </span><span style="font-size: medium;"><i>affinis</i></span><span style="font-size: medium;"> and several other species within the genus </span><span style="font-size: medium;"><i>Pterygodermatites</i></span><span style="font-size: medium;"> and determined that </span><span style="font-size: medium;"><i>cahirensis</i></span><span style="font-size: medium;"> was a valid species occurring mainly in felids.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>GEOGRAPHIC LOCATION:</b></span><span style="font-size: medium;"> This worm has been reported from cats in North Africa and the Middle East (Abdul Salam and Baker, 1990; Dalimi and Mobedi, 1992; Daoud et al., 1988; Jägerskiöld, 1909; Quentin et al., 1976; Witenberg, 1928). The worm has also been reported from cats in India (Arya, 1979 &amp; 1980; Gupta and Pande, 1970 &amp; 1977; Srivastava, 1940)</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>LOCATION IN HOST:</b></span><span style="font-size: medium;"> Small intestine.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>PARASITE IDENTIFICATION: </b></span><span style="font-size: medium;">These are white worms. The females are 8.75 to 13.5 mm long and the maoles are 3.7 to 4.8 mm long. (Jägerskiöld, 1909). The number of lateroventral spines on the male are 96 and the number of cuticular ornamentations on the lateroventral flanges of the female is 126 to 135. The ovoid eggs contain a larva, are thick shelled, and are about 30 </span><span style="font-family: 'WP MathA';"><span style="font-size: medium;"></span></span><span style="font-size: medium;">m by 40 </span><span style="font-family: 'WP MathA';"><span style="font-size: medium;"></span></span><span style="font-size: medium;">m. The distictive feature of the worm is the lateral appearance of the sclerotized buccal capsule which can be used to distinguish this species from that of </span><span style="font-size: medium;"><i>Pterygodermatites</i></span><span style="font-size: medium;"><i>affinis</i></span><span style="font-size: medium;"> of the fox. </span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>LIFE CYCLE:</b></span><span style="font-size: medium;"> The first intermediate host of </span><span style="font-size: medium;"><i>Pterygodermatites</i></span><span style="font-size: medium;"><i>cahirensis</i></span><span style="font-size: medium;"> is an arthropod, and Quentin et al. (1976) found larvae in the insect </span><span style="font-size: medium;"><i>Tachyderma</i></span><span style="font-size: medium;"><i>hispida</i></span><span style="font-size: medium;"> in Algeria. When these larvae were fed to a young cat, eggs appeared in the feces 38 days later. Witenberg (1928) and Gupta and Pande (1970) found larvae encapsulated in the wall of the intestine and in abdominal mesenteries of lizards. Gupta and Pande (1970) using larvae recovered from these lizards, successfully infected a cat experimentally. Gupta and Pande (1977) using larvae recovered from a naturally infected frog, </span><span style="font-size: medium;"><i>Rana</i></span><span style="font-size: medium;"><i>tigrina</i></span><span style="font-size: medium;">, infected puppies and found a prepatent period of 25 to 40 days.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>CLINICAL PRESENTATION AND PATHOGENESIS:</b></span><span style="font-size: medium;"> There have been no descriptions of signs associated with infections of cats with this parasite.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>TREATMENT:</b></span><span style="font-size: medium;"> There have been no attempts at treating infected cats.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>EPIZOOTIOLOGY:</b></span><span style="font-size: medium;"> The life cycle requires an arthropod intermediate host and amphibian and reptilian paratenic hosts. Thus, cats become infected by the ingestion of these hosts.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>HAZARDS TO OTHER ANIMALS:</b></span><span style="font-size: medium;"> None.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>HAZARD TO HUMANS:</b></span><span style="font-size: medium;"> None.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>CONTROL/PREVENTION:</b></span><span style="font-size: medium;"> Prevention of hunting by cats with a predisposition to prey on lizards and arthropods.</span></p> <p align="JUSTIFY"><span style="font-size: medium;"><b>REFERENCES:</b></span></p> <p align="JUSTIFY"><span style="font-size: medium;">Abdul Salam J, Baker K. 1990.
