Las políticas agrarias para el mejoramiento de la productividad pecuaria requieren información para formular estrategias de intervención, de acuerdo a las características heterogéneas de los ganaderos y el manejo de sus fincas. El objetivo del estudio fue caracterizar el componente sociodemográfico de los ganaderos y las características del sistema productivo de fincas ganaderas de las provincias de Tambopata (distrito Laberinto, Las piedras y Tambopata) y Tahuamanu (distrito Iberia e Iñapari), departamento de Madre de Dios, Perú. Se aplicó una entrevista estructurada a 183 ganaderos en los cinco Distritos, considerando 33 indicadores. Los datos se analizaron con estadística descriptiva, tablas de contingencia, asociación, ANOVA y prueba de Kruskal-Wallis, y análisis de conglomerados. Se encontró asociación significativa entre distrito con género, ocupación secundaria y ...

OBJECTIVE The objective of this study was to determine the seroprevalence of reproductive and infectious diseases in tropical cattle in the Tambopata and Tahuamanu Provinces in the department of Madre de Dios, Peru. SAMPLE 156 bovines from 7 cattle farms were sampled. These farms used exclusive grazing for food and natural mating for reproduction and did not have sanitary or vaccination programs. METHODS The serum of blood samples was subjected to ELISA with commercial kits for the detection of antibodies against Neospora caninum, Mycobacterium avium subsp paratuberculosis (MAP), Leptospira interrogans, pestivirus bovine viral diarrhea virus-1, retrovirus bovine leukemia virus (BLV), orbivirus bluetongue virus (BTV), and herpesvirus bovine herpes virus-1 (BHV). The data were analyzed by means of association tests with χ2 (P < .05) and Spearman rank correlation (P < .05) in the SPSS v.15...

Capirona (Calycophyllum spruceanum Benth.) belongs to subfamily Ixoroideae, one of the major lineages in the Rubiaceae family, and is an important timber tree. It originated in the Amazon Basin and has widespread distribution in Bolivia, Peru, Colombia, and Brazil. In this study, we obtained the first complete chloroplast (cp) genome of capirona from the department of Madre de Dios located in the Peruvian Amazon. High-quality genomic DNA was used to construct libraries. Pair-end clean reads were obtained by PE 150 library and the Illumina HiSeq 2500 platform. The complete cp genome of C. spruceanum has a 154,480 bp in length with typical quadripartite structure, containing a large single copy (LSC) region (84,813 bp) and a small single-copy (SSC) region (18,101 bp), separated by two inverted repeat (IR) regions (25,783 bp). The annotation of C. spruceanum cp genome predicted 87 protein-c...
