Bacterial communities associated with Zeldia punctata, a bacterivorous soil-borne nematode
International Microbiology - Tập 25 - Trang 207-216 - 2021
Soil inhabiting organisms are important determinants of agroecosystem productivity. Understanding the composition, the abundance, and the type of interactions established by soil microorganisms is therefore crucial to design strategies to improve agricultural practices and agroecosystem management. In this study, we collected Zeldia punctata nematodes in maize fields in South Africa and profiled t......
A new spike-in-based method for quantitative metabarcoding of soil fungi and bacteria
International Microbiology - - Trang 1-12 - 2023
Metabarcoding is a powerful tool to characterize biodiversity in biological samples. The interpretation of taxonomic profiles from metabarcoding data has been hindered by their compositional nature. Several strategies have been proposed to transform compositional data into quantitative data, but they have intrinsic limitations. Here, I propose a workflow based on bacterial and fungal cellular inte......
Traditional marketed meats as a reservoir of multidrug-resistant Escherichia coli
International Microbiology - - Trang 1-17 - 2023
This study aimed to analyze Escherichia coli from marketed meat samples in Peru. Sixty-six E. coli isolates were recovered from 21 meat samples (14 chicken, 7 beef), and antimicrobial resistance levels and the presence of mechanisms of antibiotic resistance, as well as clonal relationships and phylogeny of colistin-resistant isolates, were established. High levels of antimicrobial resistance were ......
Safety, functional properties and technological performance in whey-based media of probiotic candidates from human breast milk
International Microbiology - Tập 22 - Trang 265-277 - 2018
We aimed at isolating and characterising microorganisms present in human breast milk with probiotic potential. In an 8-week postpartum sampling period, two strains of bifidobacteria (Bifidobacterium longum LM7a and Bifidobacterium dentium LM8a’) and four strains of lactobacilli were isolated, all during the first 4-week postpartum. B. longum LM7a and B. dentium LM8a’, together with four strains pr......
Recent insight into the advances and prospects of microbial lipases and their potential applications in industry
International Microbiology - - 2024
Enzymes play a crucial role in various industrial sectors. These biocatalysts not only ensure sustainability and safety but also enhance process efficiency through their unique specificity. Lipases possess versatility as biocatalysts and find utilization in diverse bioconversion reactions. Presently, microbial lipases are gaining significant focus owing to the rapid progress in enzyme technology a......
Adaptive strategies of uropathogenic Escherichia coli CFT073: from growth in lab media to virulence during host cell adhesion
International Microbiology - - 2022
Urinary tract infections (UTIs) are a major concern in public health. The prevalent uropathogenic bacterium in healthcare settings is Escherichia coli. The increasing rate of antibiotic-resistant strains demands studies to understand E. coli pathogenesis to drive the development of new therapeutic approaches. This study compared the gene expression profile of selected target genes in the prototype......
Metataxonomic analysis of tissue-associated microbiota in grooved carpet-shell (Ruditapes decussatus) and Manila (Ruditapes philippinarum) clams
International Microbiology - Tập 24 - Trang 607-618 - 2021
Culture-dependent techniques only permit the study of a low percentage of the microbiota diversity in the environment. The introduction of next generation sequencing (NGS) technologies shed light into this hidden microbial world, providing a better knowledge on the general microbiota and, specifically, on the microbial populations of clams. Tissue-associated microbiota of Ruditapes decussatus and ......
Comparative metagenomics and microbial dynamics of jute retting environment
International Microbiology - - Trang 1-14 - 2023
Jute, eco-friendly natural fiber, depends on conventional water-based microbial retting process that suffers from the production of low-quality fiber, restricting its diversified applications. The efficiency of water retting of jute depends on plant polysaccharide fermenting pectinolytic microorganisms. Understanding the phase difference in retting microbial community composition is crucial to pro......
Genetic and morphological characterization of a new genotype of nervous necrosis virus circulating among Nile tilapia in the south of EgyptAbstract Nervous necrosis virus (NNV) is the causative agent of viral nervous necrosis in freshwater and marine fishes. In this study, NNV circulating among wild and farmed Nile tilapia (Oreochromis niloticus ) was genetically and morphologically characterized using reverse transcription polymerase chain reaction (RT-PCR), sequencing analys... ...

Isolation and characterization of a newly chrysene-degrading Achromobacter aegrifaciens
International Microbiology - - Trang 1-13 - 2023
Polycyclic aromatic hydrocarbons (PAHs) are considered substances of potential human health hazards because of their resistance to biodegradation and carcinogenic index. Chrysene is a PAH with a high molecular weight (HMW) that poses challenges for its elimination from the environment. However, bacterial degradation is an effective, environmentally friendly, and cost-effective solution. In our stu......
