RESUMENEl objetivo del presente estudio fue determinar la sensibilidad de Salmonella enterica aislada de cuyes, con signos clínicos sugerentes de salmonelosis, frente a 12 antibacterianos. Los cuyes fueron criados bajo un sistema familiar-comercial en la provincia de Carhuaz, Áncash, entre mayo a julio de 2007. Se colectó muestras de bazo, hígado y otros órganos con lesión aparente (n=65). Para el aislamiento de S. enterica se utilizaron métodos convencionales y el análisis de sensibilidad a antibacterianos fue mediante el método de difusión por discos de Kirby-Bauer. Cepas de S. enterica se aislaron en el 61.5% de los cuyes. El 100% de estas cepas (40/40) fue sensible a enrofloxacina, sulfatrimetoprim, estreptomicina y amoxicilina, el 97.5% al cloranfenicol y gentamicina, y el 92.5% a fosfomicina. Se encontraron cepas resistentes a furazolidona (15.0%) y colistina (12.5%) entre otras. Los resultados indican que la sensibilidad de S. enterica a enrofloxacina y sulfatrimetoprim, así como al cloranfenicol, gentamicina y fosfomicina, hacen de estos antibacterianos buenas alternativas para el tratamiento de la salmonelosis en las granjas estudiadas.

The objective of this study was to determine the prevalence of canine brucellosis (Brucella canis) in two districts of the province of Callao. A total of 456 sera were collected from dogs without distinction of breed, sex and age. Samples were analyzed by the Agar Gel Immunodiffusion (AGID) test using B. ovis antigen. The results indicated that 15.6 ± 3.3 (71/456) of sampled animals were positive. No statistical differences were found due to district, breed, sex or age; however, differences were found (p<0.05) beetween dogs with and without reproductive history (26.5 and 8.6% respectively).

The Principles for Responsible Investment in Agriculture and Food Systems (CFS-RAI) are shown as suitable instruments to contribute to the Sustainable Development Goals (SDG) in rural areas. Local Action Groups (LAGs) have proven to be effective governance structures for the implementation and management of rural development projects based on participation and collective action. This research integrates the implementation of the LAG from the CFS-RAI Principles for the design of a rural development strategy. The foundations of these new structures are analyzed and the process of creating a LAG linked to the El Mantaro Regional Development Center (RDC) of the Universidad Nacional Mayor de San Marcos (UNMSM), in the Junín region (Peru), is described. The methodological process incorporates the “Working With People” (WWP) approach and the LEADER (Liaison Entre Actions de Développement de l’Économie Rurale) specificities for the analysis of empirical information obtained in surveys and workshops, with 350 people involved in the process. The results indicate that the LAGs, as multi-stakeholder partnerships linked to the RDC, are a novel way to integrate the CFS-RAI principles from participation, proximity management, strengthening local communities and promoting sustainable development through projects. These results contribute to the empowerment of civil organizations and motivate their participation in local political decisions related to sustainable rural development.

RESUMENLa dermatitis bacteriana canina, comúnmente conocida como piodermia, es una de las principales enfermedades dermatológicas observadas en la clínica veterinaria. El presente estudio retrospectivo tuvo como objetivo determinar la frecuencia de los diferentes agentes bacterianos involucrados con esta enfermedad y los antibióticos que presentan mejor actividad inhibidora frente a los principales microorganismos patógenos. Para tal fin, se analizaron los registros de resultados de aislamiento bacteriano y antibiograma del Laboratorio de Bacteriología de la Facultad de Medicina Veterinaria de la Universidad Nacional Mayor de San Marcos, Lima, durante el periodo 2000-2006. El Staphlococcus intermedius fue la especie más aislada (70.6%). Los antibióticos más efectivos fueron de la familia de las cefalosporinas como el ceftiofur y la cefalexina, mientras que la penicilina fue la que presentó mayor índice de resistencia. Palabras clave: Dermatitis bacteriana canina, aislamiento bacteriano, antibiograma,Staphylococcus intermedius ABSTRACTThe canine bacterial dermatitis, commonly known as pyoderma is one of the main skin diseases in the veterinary practice. The present retrospective study had the objective to determine the frequency of the bacteriological agents involved with the disease and the antibiotics that show better antimicrobiobial susceptibility. Laboratory records of bacterial isolation and antibiogram of the Laboratory of Bacteriology of the Veterinary Medicine Faculty, San Marcos University, Lima, were analyzed. Staphlococcus intermedius was the most commonly isolated species (70.6%). The most effective
