A prospective longitudinal study was performed to determine the infectivity of Sarcocystis sp. cysts in alpacas in a livestock of the central highlands in Peru. Fifty raised male alpacas were selected at random after birth and then slaughtered, 3 monthly until one year of age, in order to detect micro or macrocysts in the skeletal and cardiac muscles. Dog groups free of parasites were infected monthly with skeletal and cardiac muscle to investigate their infectivity. The results show that the raised alpacas presented micro cysts of Sarcocystis sp. in skeletal and cardiac muscle since four months of age. We did not detect macro cysts in the skeletal muscles in the raised alpacas until the end of the experiment. Dogs feed monthly on microcysts of Sarcocystis sp since birth until a year of age but does not eliminate micro or macrocyst of Sarcocystis sp.

El presente proyecto se centra en el desarrollo de un manual de marca y una estrategia de lanzamiento digital para “Valvilla”, un estudio de uñas. A lo largo de este proyecto, se busca establecer una identidad visual alineada con los valores y objetivos de la marca, así como posicionarla de manera efectiva antes de su lanzamiento físico oficial. Esta iniciativa se llevará a cabo mediante una identidad visual innovadora para posicionar la marca y una estrategia digital orientada a generar una presencia de marca en redes sociales.

A study was performed to determine the prevalence of Sarcocystis sp. in alpacas and alpacas’ sheep dogs in a livestockcompany from the central highlands in Perú. Skeletal and cardiac muscle were examined to look for micro or macro cystsof Sarcocystis in alpacas slaughtered in the slaughterhouse. Th e macroscopic cysts were detected by direct observationand microscopic cysts by the Trichinoscope method. Fecal samples from 30% of the sheep dogs were examined by theZinc Sulphate Method. High infection levels for micro or macro cysts (75% to 100%) were found in 2, 3 and 4-yearsold alpacas, respectively, and 36% of alpaca sheep dogs were infected with oocysts or sporocysts. We discuss someepidemiological factors which contribute to the dissemination of this parasite.

A study about the prevalence of Sarcocystis sp. in bovine, ovine and goat cattle have been performed using the Trichinoscopy method into heart and esophagus tissues. The results showed that 76 samples of heart tissues from bovine positive over a total of 85 samples (89.5%); will 122 samples from ovine were positive over a total of 134 samples (91.04%). In the same tissue of goat only 33 samples (52.4%). Sarcocystis was found in esophagus the parasitism average was as follow: 2% in bovine; 39.8 in ovine and 76.2 in goat. These results achieved that the mayor parasitism in bovine and ovine is located into the heart; whilst in goat the esophagus is the tissue more infect. Therefore a high parasitism by Sarcocystis sp. has been registered in the meat of cattle used as a human food.

Se realizó un estudio a fi n de determinar la prevalencia de Sarcocystis sp. en alpacas y perros pastores de una empresaganadera de la sierra central del Perú. Se realizaron exámenes macro y microscópicos del músculo esquelético y cardiacode alpacas benefi ciadas en el camal de la empresa, a fi n de detectar los niveles de infección por micro o macroquistes,respectivamente. La edad de los animales fue determinada por la dentición. La búsqueda de quistes macroscópicos serealizó mediante el examen visual de los canales, en tanto que los quistes microscópicos se diagnosticaron mediante elMétodo del Trichinoscopio. El examen parasitológico de heces en perros pastores se efectuó en el 30 % de la población por el Método de Flotación con Solución Sobresaturada de Zinc a fin de detectar ooquistes y/o esporoquistes. Se encontróaltos niveles de infección por micro o / mac...

Trabajo presentado en la XXXVI Reunión de la Asociación Peruana de Producción Animal - APPA 2011, realizado del 29 de noviembre al 3 de diciembre.

El objetivo del estudio fue evaluar la efectividad del fipronil al 1% y de la ivermectina al 1% en el tratamiento de sarna causada por Trixacarus caviae en cuyes infestados naturalmente, durante un periodo de 42 días. Para ello se seleccionaron 21 hembras reproductoras, dividiéndose al azar en tres grupos: (a) tratado con fipronil (vía epicutánea) 1,5 ml/kg. p.v., (b) tratado con ivermectina (vía subcutánea) 0,05 ml/kg. p.v. ambos con cuatro tratamientos a intervalos de 8 días, y (c) sin tratamiento. Cada 8 días se colectó escarificaciones cutáneas de cada animal para determinar el porcentaje de ácaros vivos y se tomaron biopsias de piel de un animal por grupo para la evaluación histopatológica. Al inicio del estudio los cuyes de los tres grupos presentaron 100% de ácaros vivos, observándose al día 42 post tratamiento, una disminución de ácaros vivos hasta 11,1% en el g...
