Resumen:
There are only a few examples of parasitism affecting snakes in Argentina, and there is a limited understanding of endoparasites in wild caught snakes. The current study summarizes the parasitic infections detected in some specimens of Leptophis ahaetulla marginatus (Lam) collected in the Iguazu National Park (Misiones, Argentina), in accordance with authorization from the National Park Administration (APN) N° 335, and transported to the serpentarium of the National Institute of Tropical Medicine (INMeT) (Argentina). Ecto and Endoparasite examinations were carried out by skin scrapping and parasitological analysis of fecal samples by both sedimentation and flotation concentration techniques. Four samples (each corresponding to different specimens) were positive for presence of Ascarididae-type eggs (Lam 1), Rhabdiasidae-type eggs and larvae (Lam 2), Eimeria-type oocysts (Lam 3) and Digenean trematode eggs (Lam 4). Treatments were done with administration of: 10% fenbendazole suspension orally at a dose of 40 mg/kg, which was repeated after 6 days (for Lam 1 and 2); Trimethoprim/Sulfamethoxazole 25 mg/kg IM per day for 2 days and then one dose every two days for another 10 days (for Lam 3); Praziquantel orally at a dose of 7.5 mg/kg which was repeated after 15 days (for Lam 4). Fecal sample re-examinations were carried out after fifteen days of each treatment and they were found negative. Thus, this study provides relevant information about the parasitic fauna of wild specimens of a colubrid snake commonly found in northeastern Argentina, and gives insight into their corresponding treatment.
