Clinical records of bitches older than six months that were treated at the Small Animals Clinic of the Faculty of Veterinary Medicine of the Universidad Nacional Mayor de San Marcos during the period 2009-2013 were revised to obtain statistical information about the frequency of pyometra and its relationship with age, breed, size and season of the year. Out of 4715 records of bitches, 207 were diagnosed with pyometra, representing an incidence of 4.4 ± 0.6%. A statistical association was found between pyometra and breed, but not with the size of the animal or the season of the year.

The aim of the study was the sanitation and disinfecting llama meat naturally infected with macrocysts of Sarcocystis aucheniae through any of four physical methods: boiling (100 ºC for 10 min), baking (105 ºC for 65 min), frying and freezing (-20 ºC for 10 days). A lisis of macrocysts from treated and non-treated meats was prepared and inoculated (100 μg/kg of body weight, subcutaneously).into 30 rabbits of 4-5 months of age. Only rabbits of the positive control group (non-treated meat) died. Rabbits of the frozen meat group showed moderate toxicity signs. Furthermore, 13 puppies (2-5 months of age) were fed with 200 g of treated or non-treated infected llama meat. Puppies of meat-treated groups did not eliminate sporocysts in the feces as compared to puppies of the non-treated meat that had sporocysts after 14 days of the feeding. It can be concluded that boiling, baking, and fryin...

Con el objetivo de sanear y detoxificar la carne de llama infectada con Sarcocystis aucheniae se evaluó el efecto de los métodos físicos de cocción (100 ºC por 10 min), horneado (105 ºC por 65 min), fritura y congelado (-20 ºC por 10 días). La inactivación de la toxicidad de la proteína sarcocystina se evaluó en 30 conejos de 4-5 meses de edad que fueron inoculados s.c. con 100 μg de proteína/kg de peso vivo, obtenida de un lisado de macroquistes de S. aucheniae proveniente de carnes tratadas con cada método físico y de carne sin tratar. Únicamente los conejos del control positivo (carne sin tratar) murieron. Los conejos del grupo de carne congelada presentaron sintomatología tóxica moderada. La interrupción del ciclo biológico del S. aucheniae se evaluó en 13 perros de 2-5 meses de edad que fueron alimentados con 200 g de carne de llama tratada o sin tratar. Los per...

The objective of the present study was to experimentally reproduce the biological cycle of Echinococcus granulosus in dogs. Twelve dogs, 4-50 months old, were infected with 80,000-308,000 protoscolices recovered from lung and liver hidatyd cysts in sheep reared in the central highlands of Peru. Dogs were slaughtered 28-39 days post infection (p.i) and the small intestine was divided in three equal portions (anterior, medium, and posterior) and parasites were counted. The location of parasites in the three portions of intestine was recorded in three dogs. Eight out of 12 dogs resulted positive to the infection and the number of parasites varied from 1,299 till 65,000 per dog. Animals slaughtered on the 28th p.i day resulted negative. The preferred site for parasites was the medium portion of the small intestine. It was shown that the oral inoculation of protoscolices from sheep hydatic cy...

El presente estudio tuvo por objetivo reproducir experimentalmente el ciclo biológico del Echinococcus granulosus en perros. Se utilizó 12 perros (4-50 meses de edad) que fueron infectados experimentalmente con 80,000 a 308,000 protoescólices de quistes hidatídicos de pulmón e hígado de ovinos procedentes de Junín y Ayacucho. Los perros se sacrificaron 28 a 39 días post infección (p.i). El intestino delgado se dividió en tres porciones iguales (anterior, media y posterior). Los parásitos fueron separados del intestino y contados. Además, en tres perros se determinó el grado de dispersión del parásito en las tres porciones del intestino delgado. Ocho de los 12 perros se infectaron, recolectándose entre 1,299 a 65,000 parásitos adultos por perro. Los animales sacrificados el día 28 p.i resultaron negativos, mientras que ocho de los nueve perros sacrificados a partir del d...
