En este trabajo se han estudiado los contenidos obtenidos por medio de lavados gástricos a 53 C. acutus, en las áreas del estero el Salado, estero Boca Negra-Boca de Tomates y en la UMA Reptilario Cipactli, ubicadas en Puerto Vallarta, Jalisco, México, con el fin de conocer la helmintofauna de la especie. Se identificó solamente al nemátodo, Dujardinascaris helicina (Molin, 1860). La mayor prevalencia fue del 74% y la abundancia 3.17 en el área del estero Boca Negra-Boca de Tomates; y la menor prevalencia fue del 12%, con una abundancia de 0.76 en los ejemplares en la UMA Reptilario Cipactli. Suponemos que esta diferencia se debe principalmente al tipo de alimento suministrado a los cocodrilos en cautiverio. En esta investigación se registra por primera vez a D. helicina como parásito de C. acutus en la región.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: The river crocodile (Crocodylus acutus, Cuvier, 1807) is a protected species in Mexico. In this work the stomach contents obtained through gastric lavage of 53 C. acutus from the estuarine systems &#8220;El Salado&#8221;, &#8220;Boca Negra-Boca de Tomates&#8221; and from the &#8220;UMA (Unidad de Manejo y Conservación de Vida Silvestre&#8221; for its meaning in Spanish) Reptilario Cipactli&#8221; located in Puerto Vallarta, Jalisco, Mexico were collected to study the helminth fauna of the species. Only Dujardinascaris helicina (Molin, 1860) was identified. The highest prevalence occurred in &#8220;Boca Negra-Boca de Tomates&#8221; with 74% and an abundance of 3.17, and the lowest in &#8220;UMA Reptilario Cipactli&#8221; with 12% and an abundance of 0.76. The dissimilarity is assumed to be caused primarily by the different feeding habits between wildlife and captivity raised crocodiles. During this investigation D. helicina is registered for the first time as a parasite for C. acutus in the region.]]></p></abstract>
