<p align="JUSTIFY"><span style="font-size: medium;">This is a metastrongyloid nematode parasite of felines that occasionally finds its way into the domestic cat. </span><span style="font-size: medium;"><i>Oslerus rostratus</i></span><span style="font-size: medium;"> is a large worm that is closely related to the canine parasite </span><span style="font-size: medium;"><i>Oslerus </i></span><span style="font-size: medium;">(= </span><span style="font-size: medium;"><i>Filaroides</i></span><span style="font-size: medium;">)</span><span style="font-size: medium;"><i> osleri</i></span><span style="font-size: medium;">; some workers consider the genus </span><span style="font-size: medium;"><i>Anafilaroides</i></span><span style="font-size: medium;"> containing the genus </span><span style="font-size: medium;"><i>rostratus</i></span><span style="font-size: medium;"> to be distinct from the genus </span><span style="font-size: medium;"><i>Oslerus</i></span><span style="font-size: medium;"> (e.g., Seneviratna (1959). </span><span style="font-size: medium;"><i>Oslerus</i></span><span style="font-size: medium;"><i>rostratus</i></span><span style="font-size: medium;"> has been reported from cats in the United States, Pacific Islands, Southern Europe,and the Middle East (Gerichter, 1949; Ash, 1962; Seneviratna, 1959; Juste et al., 1992). The adult males are about 28-37 mm long, and the adult females are 48-64 mm long. The worms are typically found in the bronchial submucosa. The vulva in the female is located just anteriad to the anus. The larvae found in the feces are 335 to 412 um long and have a tail that is similar to that of </span><span style="font-size: medium;"><i>Oslerus osleri</i></span><span style="font-size: medium;">. The life cycle has been described by Gerichter (1949) and Klewer (1958) who found that the larvae were capable of development in slugs. Seneviratna (1959) has shown that the third-stage larvae from slugs are capable of infecting mice that serve as paratenic hosts. Similarly, he found that week-old chickens could be infected as paratenic hosts and that the larvae recovered from these chicks were capable of infecting a cat. Larvae were first observed in the cat 78 days after being given infective-stage larvae. There have been no studies on the signs of infection with this parasite or on effectiveness of different treatments.</span></p>
