One of these pathogens is Marek disease virus (MDV), which is an immunosuppressive agent that can cause high mortality rates and substantial production losses. Currently, there are few documented clinical cases due to the implementation of mass vaccination programs with GaHV-2 strains (serotype I) and HVT (serotype III). However, losses in production rates are likely occurring due to immunosuppression and subclinical infections. The objective of this review is to describe MDV and the current status of the infection in Colombia.","PeriodicalId":49598,"journal":{"name":"Revista Mvz Cordoba","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47493166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

EnglishABSTRACT Objective. Isolate, identify and molecularly characterize pathogenic Cryptococcus isolates for humans from environmental and clinical samples from the city of Cucuta. Materials and methods. A total of 1300 samples were collected from 446 trees of 10 different species in 10 public areas of Cucuta. Concomitantly, clinical isolates of Cryptococcus neoformans were obtained (June 2016-June 2017). The samples were cultivated in Guizottia abysinica seed medium and were then biochemically identified and characterized by PCR fingerpinting and RFLP of the URA5 gene. Results. C. neoformans displayed an environmental prevalence of 4.3% (19 positive individuals), and that of C. gattii was 0.2% (1 positive individual); this yielded a total of 20 Cryptococcus-positive trees and 21 isolates (two from the same individual). Santander Park registered 47.6% of the global prevalence (10/21 isolates), followed by La Victoria Park with 23.8% (5/21 isolates), corresponding to C. neoformans. One C. gattii isolate was collected from a Ficus benjamina tree located in Mercedes Abrego Park. Genotypic analysis revealed the presence of C. neoformans var. grubii VNI in 85.7% of environmental isolates as well as 100% of clinical isolates. VNII and VGII molecular types represented 9.5% and 4.8% of the environmental isolates, respectively. Conclusions.

Evaluar la dinámica de crecimiento y acumulación de forraje del pasto guinea (P. maximum Jacq.) cv. Mombasa, y definir el momento óptimo de cosecha. Materiales y métodos. Se evaluaron ocho tratamientos, que consistieron en cortes de forraje cada 10 días, durante las cuatro estaciones del año, bajo un diseño completamente al azar con cinco repeticiones. Al inicio de cada estación se realizó corte de uniformidad a 5 cm de altura, y se utilizaron cuadrantes (0.64 m2), para cortar el forraje a ras de suelo. Se evaluó altura de planta, acumulación de forraje, tasa de crecimiento (TC), índice de área foliar, relaciones hoja:tallo y hoja:no hoja, composición botánica y morfológica. Los datos se analizaron mediante Mixed y GLM de SAS. Resultados. La acumulación de forraje fue mayor en verano y primavera (p≤0.05). La acumulación de forraje y la TC incrementaron progresivamente hasta que el crecimiento de las hojas se estabilizó. Los incrementos posteriores de forraje se debieron al aumento de tallos y material muerto cuando la TC declinó. En verano la TC (127 kg MS ha-1d-1) superó en 26, 44 y 75% las TC de primavera, otoño e invierno. Conclusiones. De acuerdo a los resultados (estudios realizados), se sugiere que, en esta región del Estado de Chiapas, el manejo óptimo del cv.
