Investigadora del LBMCF visita el Ragon Institute

En el mes de julio de 2018 la investigadora y alumna de doctorado de la “Universidade Federal de Minas Gerais” (UFMG) MSc. Paula Luize Camargos Fonseca integrante del “Laboratório de Biologia Molecular e Computacional de Fungos” (LBMCF) realizó una visita técnica al Ragon Institute en la Ciudad de Cambridge, Massachusetts, EUA, sobre la supervisión del médico e investigador Wilfredo Beltrán con la misión de ampliar la red de colaboración de nuestro grupo de investigación. Durante la visita, Paula aprendió sobre técnicas de microscopía electrónica, biología molecular, proteómica y bioseguridad. El Reagon Institute fue creado en 2009 resultado de una colaboración entre el Massachusetts General Hospital (MGH), Massachusetts Institute of Technology (MIT) y Harvard University. El instituto desarrolla investigaciones en las áreas de virología e inmunología, específicamente con el objetivo de contribuir para los estudios del HIV y para el descubrimiento de una vacuna para combatir el virus.

Comparative mangrove metagenome reveals global prevalence of heavy metals and antibiotic resistome across different ecosystems

The mangrove ecosystem harbors a complex microbial community that plays crucial role in biogeochemical cycles. In this study, we analyzed mangrove sediments from India using de novo whole metagenome next generation sequencing (NGS) and compared their taxonomic and functional community structures to mangrove metagenomics samples from Brazil and Saudi Arabia. The most abundant phyla in the mangroves of all three countries was Proteobacteria, followed by Firmicutes and Bacteroidetes. A total of 1,942 genes were found to be common across all the mangrove sediments from each of the three countries. The mangrove resistome consistently showed high resistance to fluoroquinolone and acriflavine. A comparative study of the mangrove resistome with other ecosystems shows a higher frequency of heavy metal resistance in mangrove and terrestrial samples. Ocean samples had a higher abundance of drug resistance genes with fluoroquinolone and methicillin resistance genes being as high as 28.178% ±3.619 and 10.776% ± 1.823. Genes involved in cobalt-zinc-cadmium resistance were higher in the mangrove (23.495% ±4 .701) and terrestrial (27.479% ± 4.605) ecosystems. Our comparative analysis of samples collected from a variety of habitats shows that genes involved in resistance to both heavy metals and antibiotics are ubiquitous, irrespective of the ecosystem examined.
