The case of a 7-year-old white-winged guan (Penelope albipennis) with sudden death, owned by a zoo and rescue center in Lambayeque, Peru, is reported. At necropsy, diffusely scattered whitish spots were observed in the liver and whitish nodules of different sizes in the ovary. Histopathological examination gave the definitive diagnosis of cholangiocarcinoma in the liver and dysgerminoma in the ovary. This is the first report of these pathologies in the Penelope albipennis species in Peru.

The objective of the study was to asses the susceptibility, pathological effect and serological response of wild pigeons (Columba livia) to Newcastle virus. A total of 28 adult wild pigeons were captured, 14 were inoculated with a velogenic viscerotropic strain of Newcastle virus by oral and nasal route, and the remaining birds were used as a control group. Clinical signs and mortality were recorded. Blood samples were collected for the hemaglutination inhibition technique. Tissue samples from lung and trachea were collected, and cloacal swabs were harvested for virus recovery and histological studies. Birds of the inoculated group showed clinical signs (64%) and mortality (42.8%). The clinical signs (sneezes, ruffled plumage, isolation and lethargy) started at day 4 after inoculation. The 43% of birds showed nervous signs (opisthotonos and tremors of head and neck) and 21% had diarrhea....

El objetivo del presente estudio fue evaluar el grado de susceptibilidad, efecto patológico y respuesta serológica de la paloma silvestre (Columba livia) frente a la inoculación experimental con una cepa de virus velogénico de la enfermedad de Newcastle. Se capturaron 28 aves, donde la mitad se inoculó vía nasal y oral, y la otra mitad se mantuvo como grupo control. Se registró signos clínicos y mortalidad. Se tomaron muestras de sangre para la prueba de inhibición de la hemaglutinación y muestras de tejidos de aves muertas y del grupo control para su análisis histopatológico. Se tomaron muestras de pulmón, tráquea e hisopado de cloaca para la recuperación viral, durante seis semanas post inoculación. El 64% de aves del grupo inoculado presentó signos clínicos y una mortalidad del 42.8%. Se presentaron estornudos a partir del 4"dia; erizamiento de plumas, aislamiento y ...

The aim of this study was to develop a stochastic simulation model to estimate implementation costs of porcine cysticercosis (CP) control programmes. Three scenarios were proposed: (1) use of a commercial recombinant vaccine (RV), (2) mixed use of RV plus oxfendazole (OFZ), and (3) dosing with OFZ. To establish the efficacy of the interventions, the probabilities of elimination of cysticercosis were obtained through the “cystiSim” agent-based model. The cost model was developed in R with 10 000 iterations. It was found that the mixed scenario offered a probability of 0.987 eliminating cysticercosis in 6.5 years and with an annual cost of S/. 335,208 (95% CI: S/ 309,922 – 368,698) (1 US$ = S/. 3.75). In contrast, the dosing strategy with OFZ proved to be less expensive with S/. 260,518 (95% CI: S/ 237,559 – 293,704) per year and a probability of elimination of 0.951...
