Evalúa la osteomielitis del maxilar de 21 alpacas adultas, seis tuis y tres crías mediante el examen clínico, anatomopatológico, y microbiológico. En todos los casos se hallaron lesiones de osteomielitis exclusivamente en el maxilar inferior y más frecuentemente en el maxilar izquierdo. Las lesiones leves son engrosamientos focalizados, mientras que las lesiones moderadas y graves son multifocales con la presencia de ulceraciones y fístulas directamente relacionadas a la gravedad de la lesión. A nivel histológico, se observa que la osteomielitis del maxilar inferior es un proceso agudo, crónico primario y crónico secundario. Concluye que la osteomielitis de las alpacas es una enfermedad debilitante, progresiva desde leve a grave, que afecta a cualquier edad, es polimicrobial e invasiva desde una lesión inicial y que conlleva a la muerte sobre todo en crías.

            The aim of this study was to analyse the production of vicuña (Vicugna mensalis mensalis) fibre in semi-captivity and in the wild between 2008 and 2016 in the Apurímac region of Peru, as well as to determine the population of vicuñas captured and sheared and the effect of sex, age and management system in the fibre production. The production of vicuña fibre in the nine years of the study was 2 623 kg, annual average of 295.7 kg, yield of 152.76 g/vicuña and a range of variation of 54-426 g. Fibre production had an annual growth rate of 9.45% and a capture rate of 10.34%. Factorial analysis showed a significant difference (p<0.05) for the interactions of years, age, sex and simple effects.
