La presente investigación se realizó con el objetivo de evaluar la patogenicidad in vitro del hongo Beauveria peruviensis sobre garrapatas Rhipicephalus microplus, en estadio de teleoginas. En el bioensayo, se sometió a tratamientos con soluciones del hongo Beauveria peruviensis en concentraciones de 1x109, 1x108 y 1x107 conidios / mL, donde se evaluó la mortalidad de teleoginas, inhibición de la ovoposición. Como resultado, se obtuvo una mortalidad de 92 %, 80 % y 64 %. En cuanto a la inhibición de la ovoposición, esta fue del 60%, 32% y 16% con los tratamientos 1x109, 1x108 y 1x107 conidios / mL respectivamente. La prueba de Dunnet indicó que todos los tratamientos muestran una diferencia significativa con el testigo, con un nivel de confianza del 99.95 %. En conclusión, el hongo Beauveria peruviensis es patógeno para Rhipicephalus microplus en el estadio de teleoginas.

Con el objetivo de evaluar la influencia de la calidad del agua y el manejo en la condición sanitaria de la trucha arcoíris (Oncorhynchus mykiss) en piscigranjas de la región Amazonas se realizó el análisis físico-químico y microbiológico del agua en 14 piscigranjas de la región Amazonas, una encuesta a los productores y se evaluaron 140 muestras de trucha en etapa comercial con el fin de identificar lesiones macroscópicas. Los datos fueron analizados usando el software Statistix versión 8.0 mediante el análisis de varianza, prueba t de Student, prueba de comparación de Tuckey y la correlación de rangos de Spearman. El análisis microbiológico muestra que 6 piscigranjas evaluadas se encuentran por encima de los límites máximos permitidos para coliformes fecales (200 NMP/ml) y los análisis de correlación evidencian asociación altamente significativa (p<0.01) entre p...

The aim of this study was to determine the prevalence of Fasciola hepatica and gastrointestinal parasites in bovines from five districts of the Amazon Region, Peru. A total of 803 bovine faecal samples were collected between October and December 2015 and were analyzed by the coprological spontaneous sedimentation technique. The results indicated a global prevalence of F. hepatica of 59.5%, with a higher prevalence in the districts of Yambrasbamba and Florida, while the prevalence of gastrointestinal parasites was 29.1%, predominating in the districts of Molinopampa and Huambo. The variables origin, category and breed were factors that influenced the degree of infestation by F. hepatica and gastrointestinal parasites (p<0.05), while sex was not significant.

OBJECTIVE This study aimed to report the impact of production practices and sanitary management on the prevalence of Neospora caninum (N caninum) and bluetongue virus (BTV) in Creole goats from the tropical dry forest of Utcubamba, Peru. METHODS 354 blood samples were obtained from male and female goats of diverse ages reared under an extensive productive system. The diagnosis of N caninum and BTV was conducted through a commercial ELISA kit (iD.vet) with readings taken on a Bio-Rad iMark microplate reader at 450 nm. Additionally, a survey was conducted with 18 goat producers to categorize them based on social, technical (production, health, reproduction, nutrition, and infrastructure), environmental, and economic factors. RESULTS The overall seroprevalence of N caninum and BTV in goats was 6.21% and 7.06%, respectively, Notably, group II farmers had the highest prevalence rates at 7.69%...
