Microbial communities from arid environments on a global scale: a systematic review

Biol. Res; 53 (), 2020
Abstract Arid environments are defined by the lack of water availability, which is directly related to the mean annual precipitation (MAP), and high values of solar irradiation, which impacts the community composition of animals, plants, and the microbial structure of the soil. Recent advances in NGS tec...

Bacterial community structure in soils contaminated with electronic waste pollutants from Delhi NCR, India

Background: Microbial community analysis of electronic waste (e-waste)-polluted environments is of interest to understand the effect of toxic e-waste pollutants on the soil microbial community and to evaluate novel microorganisms resisting the toxic environment. The present study aims to investigate the ...

Bacterial degradation of dissolved organic matter released by Planktothrix agardhii (Cyanobacteria)

Braz. j. biol; 78 (1), 2018
Abstract Although Planktothrix agardhii often produces toxic blooms in eutrophic water bodies around the world, little is known about the fate of the organic matter released by these abundant Cyanobacteria. Thus, this study focused in estimating the bacterial consumption of the DOC and DON (dissolved org...

Next-generation sequencing analysis reveals high bacterial diversity in wild venomous and non-venomous snakes from India

The oral cavities of snakes are replete with various types of bacterial flora. Culture-dependent studies suggest that some of the bacterial species are responsible for secondary bacterial infection associated with snakebite. A complete profile of the ophidian oral bacterial community has been unreported ...

Reporte de dos casos de inusual infección no letal por Chromobacterium violaceum. Revisión literaria

Infectio; 21 (2), 2017
Chromobacterium violaceum es una bacteria gramnegativa anaeróbica facultativa, que habita en el suelo y el agua de las áreas tropicales y subtropicales. La infección en seres humanos es rara. A continuación se presentan dos casos; una lactante mayor, indígena, quien posterior a baño de inmersión e...

Proteobacteria, extremophiles and unassigned species dominate in a tape-like showerhead biofilm

Braz. j. microbiol; 47 (2), 2016
Abstract The development of showerhead biofilms exposes the user to repeated contact with potentially pathogenic microbes, yet we know relatively little about the content of these aggregates. The aim of the present study was to examine the microbial content of tape-like films found protruding from a dome...

Um novo gene de Pseudomonas aeruginosa envolvido em percepção de quórum

Pseudomonas aeruginosa é uma gamaproteobactéria com capacidade de colonizar diversos tipos de ambiente e infectar hospedeiros filogeneticamente distintos. Em humanos, comporta-se como um patógeno oportunista,estando frequentemente relacionada à infecções em indivíduos imunocomprometidos e indivíd...

Acidobacteria appear to dominate the microbiome of two sympatric Caribbean Sponges and one Zoanthid

Biol. Res; 47 (), 2014
BACKGROUND: Marine invertebrate-associated microbial communities are interesting examples of complex symbiotic systems and are a potential source of biotechnological products. RESULTS: In this work, pyrosequencing-based assessment from bacterial community structures of sediments, two sponges, and one zoa...
