“…As regards the expected scenarios in this kind of analysis, extensive studies focusing on the impact of manure or chemical fertilizers in arable soils report that the application of those could significantly change the soil bacterial community [8]. The phenomenon can be neither general nor permanent, as some authors demonstrated that specific soil taxa as Pseudomonas could be temporarily affected, depending on the type of organic fertilizer [5].…”

“…Estimates indicate that one gram of soil may harbor between 2 × 10 3 and 8.3 × 10 5 different species [1,2]. Currently, surveys and counts rely on high throughput metagenomic approaches [3][4][5][6][7][8]. Bacteria, archaea and fungi adapted to live in soil can regulate plant growth and health through their direct role in processes, such as organic matter decomposition, nutrient cycling and pathogen control.…”

Response of Bacterial Communities upon Application of Different Innovative Organic Fertilizers in a Greenhouse Experiment Using Low-Nutrient Soil Cultivated with Cynodon dactylon

Assessing the response of microbial communities to nutrient inputs in man-managed soils is of primary importance to understand the impact on ecosystem services provided by the soil microbiome. In this study, a low-nutrient soil was supplemented with seven different innovative fertilizers including matrixes of plant, animal, fungal or synthetic origin, and dosed to deliver the same amount of nitrogen. Growth of a potted grass crop (Cynodon dactylon) was recorded and the fertilizers were scored by the plant yield obtained in a greenhouse study. Soil was sampled at 9 and 58 days after the addition and bacterial community composition was analyzed after soil DNA extraction through pyrosequencing of 16S rDNA gene amplicons. Over 900 bacterial genera were detected, belonging to 21 described and 19 candidate phyla. In spite of the equal dose of nitrogen delivered, specific groups were fostered by given fertilizers; in particular marked effects on some phyla were displayed by a yeast-based fertilizer, which was also most effective in plant productivity. The main shifts were observed shortly after the fertilizer application, followed by a gradual stabilization of the equilibrium and by a rise in community evenness.

Summary The gut microbiome functions like an endocrine organ, generating bioactive metabolites, enzymes or small molecules that can impact host physiology. Gut dysbacteriosis is associated with many intestinal diseases including (but not limited to) inflammatory bowel disease, primary sclerosing cholangitis‐IBD, irritable bowel syndrome, chronic constipation, osmotic diarrhoea and colorectal cancer. The potential pathogenic mechanism of gut dysbacteriosis associated with intestinal diseases includes the alteration of composition of gut microbiota as well as the gut microbiota–derived signalling molecules. The many correlations between the latter and the susceptibility for intestinal diseases has placed a spotlight on the gut microbiome as a potential novel target for therapeutics. Currently, faecal microbial transplantation, dietary interventions, use of probiotics, prebiotics and drugs are the major therapeutic tools utilized to impact dysbacteriosis and associated intestinal diseases. In this review, we systematically summarized the role of intestinal microbiome in the occurrence and development of intestinal diseases. The potential mechanism of the complex interplay between gut dysbacteriosis and intestinal diseases, and the treatment methods are also highlighted.

“…These genes and microorganisms are discharged into environmental segments through human and animal waste such as manure, sewage sludge and waste water [23]. In this way, simultaneous release of antibiotics and other selective agents promotes the selection of organisms containing resistance genes [24][25][26].…”

Currently, leafy green salads are often consumed because they are considered as practical and healthy. However, during their preparation, both inadequate washing and contact with non-hygienic surfaces may increase their microbial load. This may cause several health problems for individuals consuming salads. The overuse of antibiotics has led to the emergence of multidrug resistant bacteria, including foodborne pathogens. Biofilm production ability of these pathogenic bacteria makes it difficult to treat infections caused by these pathogens. The aim of this study is to isolate and identify P. fluorescens from leafy green salads collected from different restaurants. A total of 72 isolates were isolated from leafy green salads, and 29 of these isolates were identified by PCR as Pseudomonas and 9 of them identified as P. fluorescens. All P. fluorescens isolates were resistant to ampicillin, amoxicillin, cefuroxime, ceftazidime and ceftriaxone antibiotics. The results of this study showed that additional attention for the hygiene conditions is needed during the preparation and storage stages of leafy green salads.
