Abstract
Engine oil spills have been associated with a wide range of human health problems. However, little is known about the effects of petroleum hydrocarbon pollution on soil microbial communities. In this study, three samples were collected from oil-polluted soils (OPS), and one control soil (CS) from Taolin town, China, near the old engine's scrapes was used. The aims of this study were to conduct metagenomic sequencing and subsequently perform resistome and virulome analysis. We also aimed to validate anti-microbial resistance and virulence genes and anti-bacterial sensitivity profiles among the isolates from oil-polluted soils. The OPS microbial community was dominated by bacterial species compared to the control samples which were dominated by metazoans and other organisms. Secondly, the resistosome and virulome analysis showed that ARGs and virulence factors were higher among OPS microbial communities. Antibiotic susceptibility assay and qPCR analysis for ARGs and virulence factors showed that the oil-polluted soil samples had remarkably enhanced expression of these ARGs and some virulence genes. Our study suggests that oil pollution contributes to shifting microbial communities to more resilient types that could survive the toxicity of oil pollution and subsequently become more resilient in terms of higher resistance and virulence potential.

Abstract
The spreading of antimicrobial resistance (AMR) in crops and food products represents a global concern. In this study, we conducted a survey of resistomes in maize rhizosphere from Michigan, California, the Netherlands, and South Africa, and investigated potential associations with host bacteria and soil management practices in the crop field. For comparison, relative abundance of antibiotic resistance genes (ARGs) is normalized to the size of individual metagenomes. Michigan maize rhizosphere metagenomes showed the highest abundance and diversity of ARGs, with the detection of blaTEM-116, blaACT-4/-6, and FosA2, exhibiting high similarity (≥ 99.0%) to those in animal and human pathogens. This was probably related to the decade-long application of manure/composted manure from antibiotic-treated animals. Moreover, RbpA, vanRO, mtrA, and dfrB were prevalently found across most studied regions, implying their intrinsic origins. Further analysis revealed that RbpA, vanRO, and mtrA are mainly harbored by native Actinobacteria with low mobility since mobile genetic elements were rarely found in their flanking regions. Notably, a group of dfrB genes are adjacent to the recombination binding sites (attC), which together constitute mobile gene cassettes, promoting the transmission from soil bacteria to human pathogens. These results suggest that maize rhizosphere resistomes can be distinctive and affected by many factors, particularly those relevant to agricultural practices.

Abstract
Land-use conversion changes soil properties and their microbial communities, which, combined with the overuse of antibiotics in human and animal health, promotes the expansion of the soil resistome. In this context, we aimed to profile the resistome and the microbiota of soils under different land practices. We collected eight soil samples from different locations in the countryside of São Paulo (Brazil), assessed the community profiles based on 16S rRNA sequencing, and analyzed the soil metagenomes based on shotgun sequencing. We found differences in the communities' structures and their dynamics that were correlated with land practices, such as the dominance of Staphylococcus and Bacillus genera in agriculture fields. Additionally, we surveyed the abundance and diversity of antibiotic resistance genes (ARGs) and virulence factors (VFs) across studied soils, observing a higher presence and homogeneity of the vanRO gene in livestock soils. Moreover, three β-lactamases were identified in orchard and urban square soils. Together, our findings reinforce the importance and urgency of AMR surveillance in the environment, especially in soils undergoing deep land-use transformations, providing an initial exploration under the One Health approach of environmental levels of resistance and profiling soil communities.

Abstract
Environmental microorganisms usually exhibit a high level of genomic plasticity and metabolic versatility that allow them to be well-adapted to diverse environmental challenges. This study used shotgun metagenomics to decipher the functional and metabolic attributes of an uncultured Paracoccus recovered from a polluted soil metagenome and determine whether the detected attributes are influenced by the nature of the polluted soil. Functional and metabolic attributes of the uncultured Paracoccus were elucidated via functional annotation of the open reading frames (ORFs) of its contig. Functional tools deployed for the analysis include KEGG, KEGG KofamKOALA, Clusters of Orthologous Groups of proteins (COG), Comprehensive Antibiotic Resistance Database (CARD), and the Antibiotic Resistance Gene-ANNOTation (ARG-ANNOT V6) for antibiotic resistance genes, TnCentral for transposable element, Transporter Classification Database (TCDB) for transporter genes, and FunRich for gene enrichment analysis. Analyses revealed the preponderance of ABC transporter genes responsible for the transport of oligosaccharides (malK, msmX, msmK, lacK, smoK, aglK, togA, thuK, treV, msiK), monosaccharides (glcV, malK, rbsC, rbsA, araG, ytfR, mglA), amino acids (thiQ, ynjD, thiZ, glnQ, gluA, gltL, peb1C, artP, aotP, bgtA, artQ, artR), and several others. Also detected are transporter genes for inorganic/organic nutrients like phosphate/phosphonate, nitrate/nitrite/cyanate, sulfate/sulfonate, bicarbonate, and heavy metals such as nickel/cobalt, molybdate/tungstate, and iron, among others. Antibiotic resistance genes that mediate efflux, inactivation, and target protection were detected, while transposable elements carrying resistance phenotypes for antibiotics and heavy metals were also annotated. The findings from this study have established the resilience, adaptability, and survivability of the uncultured Paracoccus in the hydrocarbon-polluted soil.

Influence of site-specific factors on antibiotic resistance in agricultural soils of Yangtze River Delta: An integrated study of multi-factor modeling. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 838:156474.

Abstract
Agricultural soils are important reservoirs for antibiotic resistance genes (ARGs), which is closely linked to soil microorganisms. Environmental factors and co-existed pollutants may function as promoters or inhibitors for ARG proliferation to influence the agriculture green development. However, research focusing on the interaction of potential environmental drivers and ARGs is still lacking in agricultural soils. Here, we explored the microbial profile in 241 soil samples in Yangtze River Delta, and analyzed the relationship of microbial structures, ARGs, and typical site-specific factors. We found that the abundance of most ARGs was negatively correlated with the ratio of fungi and bacteria (F/B), whereas positively correlated with the ratio of gram-positive and gram-negative microbes (G+/G-). The co-occurrence network revealed significant associations among 18 site-specific factors, including 6 meteorological factors, 5 soil physicochemical properties, 5 co-existed organic pollutants, and 2 co-existed heavy metals. Random forest analysis demonstrated that F/B was mainly influenced by soil organic matters and co-existed polychlorinated biphenyls, while G+/G- was predominately regulated by soil total phosphorus and moisture content, which possibly resulting in their difference relationship with ARG abundance. Besides, the contribution of meteorological factors (>30%) in the explanation for F/B and G+/G- structures was the highest among all the site-specific factors. Together with path analysis showing meteorological factors probably affecting the ARG abundance through direct positive ways or indirect paths via physicochemical properties, microbial structure, and co-existed organic pollutants, we considered meteorological factors as the potential promoters for ARG proliferation. Collectively, these results increase our understanding of agricultural soils as hotspots of ARGs, and highlight the underappreciated role of meteorological factors as potential promoters for soil ARGs, providing reference for us to regulate ARG pollution scientifically to improve the development of green agriculture.

Metagenomic insights into the microbial community structure and resistomes of a tropical agricultural soil persistently inundated with pesticide and animal manure use. Folia Microbiol (Praha) 2022; 67:707-719. [PMID: 35415828 DOI: 10.1007/s12223-022-00970-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Accepted: 04/05/2022] [Indexed: 11/04/2022]
Abstract
Persistent use of pesticides and animal manure in agricultural soils inadvertently introduced heavy metals and antibiotic/antibiotic resistance genes (ARGs) into the soil with deleterious consequences. The microbiome and heavy metal and antibiotic resistome of a pesticide and animal manure inundated agricultural soil (SL6) obtained from a vegetable farm at Otte, Eiyenkorin, Kwara State, Nigeria, was deciphered via shotgun metagenomics and functional annotation of putative ORFs (open reading frames). Structural metagenomics of SL6 microbiome revealed 29 phyla, 49 classes, 94 orders, 183 families, 366 genera, 424 species, and 260 strains with the preponderance of the phyla Proteobacteria (40%) and Actinobacteria (36%), classes Actinobacteria (36%), Alphaproteobacteria (18%), and Gammaproteobacteria (17%), and genera Kocuria (16%), Sphingobacterium (11%), and Brevundimonas (10%), respectively. Heavy metal resistance genes annotation conducted using Biocide and Metal Resistance Gene Database (BacMet) revealed the detection of genes responsible for the uptake, transport, detoxification, efflux, and regulation of copper, cadmium, zinc, nickel, chromium, cobalt, selenium, tungsten, mercury, and several others. ARG annotation using the Antibiotic Resistance Gene-annotation (ARG-ANNOT) revealed ARGs for 11 antibiotic classes with the preponderance of β-lactamases, mobilized colistin resistance determinant (mcr-1), macrolide-lincosamide-streptogramin (MLS), glycopeptide, and aminoglycoside resistance genes, among others. The persistent use of pesticide and animal manure is strongly believed to play a major role in the proliferation of heavy metal and antibiotic resistance genes in the soil. This study revealed that agricultural soils inundated with pesticide and animal manure use are potential hotspots for ARG spread and may accentuate the spread of multidrug resistant clinical pathogens.
