Cattan Carezza Botto-Mahan Fernando Torres-Pérez Biología Host Rattus switching nematodes filarioid We report the first record of Litomosoides pardinasi in native and exotic rodents from Chile. Litomosoides pardinasi , described in the Argentine Patagonia parasitizing Phyllotis xanthopygus and Oligoryzomys longicaudatus , was found in Chile parasitizing the peritoneal and thoracic cavities of O. longicaudatus (prevalence (P)= 18.9%, mean intensity (MI)= 57.3) and Phyllotis darwini (P= 4.2%, MI= 10), and in the peritoneal cavity of Rattus rattus (P= 1.24%; MI= 22.5). Total P in native rodents from Chile was significantly lower than in Argentina, while the total MI was higher. Prevalence and MI of L. pardinasi in O. longicaudatus from Chile and Argentina showed non-significant differences; prevalence in P. darwini from Chile was significantly lower than in P. xanthopygus from Argentina and than in Chilean O. longicaudatus . Our results, together with those from Argentina, support the hypothesis that L. pardinasi is well established in O. longicaudatus , but seems to be recently acquired by P. darwini and the exotic R. rattus . Considering the known host distribution of Litomosoides species among the sigmodontines, our results also support the hypothesis that L. pardinasi first colonized the Oryzomyini tribe and later, by different phenomena of host-switching, colonized the Phyllotini tribe and the exotic R. rattus. 2014 artículo científico 1870-3453 https://www.redalyc.org/articulo.oa?id=42532670003 en http://www.redalyc.org/revista.oa?id=425 Revista Mexicana de Biodiversidad application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Biodiversidad (México) Num.4 Vol.85 |
