Abstract
Multidrug resistance (MDR) has become an increasing threat to global health because bacteria can develop resistance to antibiotics over time. Scientists worldwide are searching for new approaches that go beyond traditional antibiotic discovery and development pipelines. Advances in genomics, however, opened up an unexplored therapeutic opportunity for the discovery of new antibacterial agents. Genomic approaches have been used to discover several novel antibiotics that target critical processes for bacterial growth and survival, including histidine kinases (HKs), LpxC, FabI, peptide deformylase (PDF), and aminoacyl-tRNA synthetases (AaRS). In this review, we will discuss the use of microbial genomics in the search for innovative and promising drug targets as well as the mechanisms of action for novel antimicrobial agents. We will also discuss future directions on how the utilization of the microbial genomics approach could improve the odds of antibiotic development having a more successful outcome.

Abstract
To fight nosocomial infections, the excessive use of antibiotics has led to the emergence of multidrug-resistant microorganisms, which are now considered a relevant public health threat by the World Health Organization. To date, most antibacterial systems are based on the use of petro-sourced polymers, but the global supplies of these resources are depleting. Besides, silver NPs are widely accepted as the most active biocide against a wide range of bacterial strains but their toxicity is an issue. The growing interest in natural products has gained increasing interest in the last decade. Therefore, the design of functional antibacterial materials derived from biomass remains a significant challenge for the scientific community. Consequently, attention has shifted to naturally occurring substances such as essential oils (EOs), which are classified as Generally Recognized as Safe (GRAS). EOs can offer an alternative to the common antimicrobial agents as an inner solution or biocide agent to inhibit the resistance mechanism. Herein, this review not only aims at providing developments in the antibacterial modes of action of EOs against various bacterial strains and the recent advances in genomic and proteomic techniques for the elucidation of these mechanisms but also presents examples of biobased polymer resource-based EO materials and their antibacterial activities. Especially, we describe the antibacterial properties of biobased polymers, e.g. cellulose, starch, chitosan, PLA PHAs and proteins, associated with EOs (cinnamon (CEO), clove (CLEO), bergamot (BEO), ginger (GEO), lemongrass (LEO), caraway (CAEO), rosemary (REO), Eucalyptus globulus (EGEO), tea tree (TTEO), orange peel (OPEO) and apricot (Prunus armeniaca) kernel (AKEO) essential oils). Finally, we discuss the influence of EOs on the mechanical strength of bio-based materials.

Abstract
Glyphosate is a broad-spectrum herbicide that has been widely used for nonselective weed control in soybean fields. In the present study, RNA-seq of an Fusarium verticillioides isolate exhibiting resistance to 120 mM glyphosate revealed gene expression occurring in the presence of glyphosate and led to the identification and screening of candidate genes. A transcriptome analysis revealed 5,548 and 5,361 differentially expressed genes (DEGs) in the glyphosate resistant (GR) Fusarium verticillioides isolate treated with 45 and 90 mM glyphosate, respectively. The gene ontology (GO) pathways associated with these differentially expressed genes primarily included metabolic process, amine metabolic process, cellular aromatic compound metabolism and stress response. The primary Kyoto Encyclopedia of Genes and Genomes (KEGG) metabolic pathways included biosynthesis of secondary metabolites, carbon metabolism, glycolysis/gluconeogenesis, and nitrogen metabolism. The glyphosate degradation-related gene fv04, which belongs to the 3-isopropylalate dehydratase of the aconitase superfamily, was cloned to generate the prokaryotic expression vector pET-29b-fv04, which could be stably expressed in E. coli and promote the degradation of 52.3% of 500 mg/L glyphosate in 72 h. The results of the present study provide new ideas and insights for the acquisition of glyphosate resistance resources.

Abstract
Antibiotic resistance is a major global health issue that has seen alarming rates of increase in all parts of the world over the past two decades. The surge in antibiotic resistance has resulted in longer hospital stays, higher medical costs, and elevated mortality rates. Constant attempts have been made to discover newer and more effective antimicrobials to reduce the severity of antibiotic resistance. Plant secondary metabolites, such as essential oils, have been the major focus due to their complexity and bioactive nature. However, the underlying mechanism of their antimicrobial effect remains largely unknown. Understanding the antimicrobial mode of action of essential oils is crucial in developing potential strategies for the use of essential oils in a clinical setting. Recent advances in genomics and proteomics have enhanced our understanding of the antimicrobial mode of action of essential oils. We might well be at the dawn of completing a mystery on how essential oils carry out their antimicrobial activities. Therefore, an overview of essential oils with regard to their antimicrobial activities and mode of action is discussed in this review. Recent approaches used in identifying the antimicrobial mode of action of essential oils, specifically from the perspective of genomics and proteomics, are also synthesized. Based on the information gathered from this review, we offer recommendations for future strategies and prospects for the study of essential oils and their function as antimicrobials.

Abstract
European goldenrod (Solidago virgaurea L.) has long been applied in traditional medicine and recommended in the prophylaxis of urinary tract infections (UTIs). However, research describing the antibacterial properties of goldenrod is very limited. Therefore, the aim of the study was to determine the effect of S. virgaurea extract on the survival and biofilm formation of uropathogenic Escherichia coli. The interactions between the goldenrod extract and antibiotics used in UTIs were established. The influence of the extract on the duration of the post-antibiotic effects (PAE) and post-antibiotic sub-MIC effects (PASME) of amikacin and ciprofloxacin were determined. Extract composition was analyzed using coupled UHPLC/MS and the spectrophotometric method. The survival of bacteria was established using the serial dilution assay. The crystal violet assay for biofilm quantification was also used. PAE and PASME were investigated using the viable count method. The obtained results indicate that S. virgaurea extract limits the survival of planktonic forms of bacteria and reduces 24-h biofilm. However, the combination of S. virgaurea extract with antibiotics weakens their antibacterial activity and shortens the duration of PAE and PASME. Therefore, when deciding to use a combination of S. virgaurea extract and amikacin/ciprofloxacin, it is necessary to take into account their antagonistic activity.

Abstract
OBJECTIVE This study aimed to investigate the distribution of multidrug-resistant organisms in pediatric patients with infectious pneumonia and to analyze their resistance and risk factors. METHODS Pediatric patients infected with five MDROs (MRSA, MDR-PA, MDRAB, ESBL KP, and ESBL E. coli) and five sensitive bacteria (MSSA, PA, AB, KP, and E. coli) were recruited as the study cohort. The distribution of the MDROs and the risk factors for MDRO-infected pneumonia were investigated. The two groups' treatment costs, hospitalization times, and prognoses were compared. RESULTS A total of 219 children were included, including 3 cases of mixed infections with MDRO and sensitive bacteria (1.37%), 110 cases of MDRO infections (50.23%), and 106 cases of sensitive bacterial infections (48.40%). Imipramine was sensitive to MDR-PA, MDRAB, ESBL KP, and ESBL E. coli, and vancomycin was sensitive to MRSA. A logistic regression model and a multifactorial analysis showed that ICU treatment, mechanical ventilation, arterial and venous intubation, fiberoptic bronchoscopy, concomitant chronic lung disease, and chronic cardiovascular disease were the independent risk factors for MDRO (P < 0.05). The hospitalization times, the treatment costs, and the 30-day mortality rate of the children in the MDRO group were significantly higher than they were in the children infected with sensitive bacteria (P < 0.05). CONCLUSION Vancomycin or imipenem may result in good clinical outcomes in children treated in the ICU subject to mechanical ventilation, arterial and venous intubation, fiberoptic bronchoscopy, the overuse of antimicrobial drugs, and children with concomitant chronic lung disease or chronic cardiovascular disease.

Abstract
Antimicrobial resistance (AMR) has been identified as one of the biggest health threats in the world. Current therapeutic options for common infections are markedly limited due to the emergence of multidrug resistant pathogens in the community and the hospitals. The role of different essential oils (EOs) and their derivatives in exhibiting antimicrobial properties has been widely elucidated with their respective mechanisms of action. Recently, there has been a heightened emphasis on lavender essential oil (LEO)’s antimicrobial properties and wound healing effects. However, to date, there has been no review published examining the antimicrobial benefits of lavender essential oil, specifically. Previous literature has shown that LEO and its constituents act synergistically with different antimicrobial agents to potentiate the antimicrobial activity. For the past decade, encapsulation of EOs with nanoparticles has been widely practiced due to increased antimicrobial effects and greater bioavailability as compared to non-encapsulated oils. Therefore, this review intends to provide an insight into the different aspects of antimicrobial activity exhibited by LEO and its constituents, discuss the synergistic effects displayed by combinatory therapy involving LEO, as well as to explore the significance of nano-encapsulation in boosting the antimicrobial effects of LEO; it is aimed that from the integration of these knowledge areas, combating AMR will be more than just a possibility.

Abstract
The emergence of antimicrobial resistance (AMR) has urged researchers to explore therapeutic alternatives, one of which includes the use of natural plant products such as essential oils (EO). In fact, EO obtained from clove, oregano, thymus, cinnamon bark, rosemary, eucalyptus, and lavender have been shown to present significant inhibitory effects on bacteria, fungi, and viruses; many studies have been done to measure EO efficacy against microorganisms. The strategy of combinatory effects via conventional and non-conventional methods revealed that the combined effects of EO-EO or EO-antibiotic exhibit enhanced efficacy. This paper aims to review the antimicrobial effects of EO, modes of EO action (membrane disruption, efflux inhibition, increase membrane permeability, and decrease in intracellular ATP), and their compounds' potential as effective agents against bacteria, fungi, and viruses. It is hoped that the integration of EO applications in this work can be used to consider EO for future clinical applications.
