Amphibians have developed different strategies to protect eggs, tadpoles, and froglets. Seven modes of parental care are known: egg attendance, egg transport, tadpole attendance, tadpole transport, tadpole feeding, internal gestation, and froglet transport. Brachycephaloidea (Terrarana) includes 1073 species f which are known to provide parental care. In Peru, seven species of Craugastoridae are known to exhibit parental care, including Bryophryne cophites, Lynchius oblitus Motta, Chaparro, Pombal, Guayasamin, De la Riva, and Padial, 2016.

Fasciola hepatica resistance in sheep against albendazole and triclabendazole was evaluated in two farms in La Paz, Bolivia: one located near Tambillo (farm 1) and the other near Batallas (farm 2). Thirty male lambs of 7 to 8 months of age were selected in each farm. They were treated with 10 mg/kg of albendazole or 10 mg/kg of triclabendazole, and one group remained as non-treated. The gama glutamyl transpeptidase enzyme (GGT) profile and faecal eggs count reduction test (FECRT) were conducted. Lambs were slaughtered 8 weeks after treatment and the number of flukes in liver was counted. Minor reduction of GGT levels and faecal eggs count were observed in animals treated with albendazole. In the group treated with triclabendazole in farm 1 was observed a reduction of the GGT levels and faecal eggs count throughout the study, but not in farm 2. The reduction of flukes in liver lambs was 1...

Se determinó la resistencia de Fasciola hepatica frente a albendazol y triclabendazol en ovinos de dos rebaños en La Paz, Bolivia: uno cercano a Tambillo (rebaño 1) y otro cercano a Batallas (rebaño 2). Se eligió al azar 30 corderos de 8 a 9 meses de edad por rebaño, y se trataron con 10 mg/kg de albendazol ó 10 mg/kg de triclabendazol, quedando un grupo como control no tratado. Se midió la enzima gama glutamil transpeptidasa (GGT) y el número de huevos por gramo de heces (hpg) para la prueba de reducción de la oviposición. Los corderos se sacrificaron 8 semanas después del tratamiento y se contó el número de fasciolas. Se presentó una baja reducción de los niveles de GGT y de hpg en los grupos tratados con albendazol. En el grupo tratado con triclabendazol en el rebaño 1 se observó una de reducción de los niveles de GGT y hpg durante todo el estudio, no así en el reb...
