Bacterial pathogens escaping from control by antibiotics are well defined and resistance develops over decades while a next viral pandemic occurs suddenly with a novel virus. The death toll for resistant bacterial infections is reviewed and the scientific and economic hurdles to the development of new antibiotics are discussed. Regulatory adaptations and financial push and pull programs to restimulate new antibiotic development are explored. The COVID-19 pandemic caused not only millions of deaths, but also economic losses in excess of 10 trillion US dollars. Coronaviruses and influenza viruses remain usual suspects for new viral pandemics, followed by paramyxoviruses. Viral infections at the animal-human interface in wet markets and in disturbed environments need active virus surveillance programs. Learning lessons from the COVID-19 for non-pharmaceutical interventions are difficult to draw since measures were frequently applied in combination and against different variant viruses and against changing population immunity levels. The RECOVERY clinical trials demonstrated that even under emergency situations clinical trials can rapidly provide solid treatment data. Various novel vaccine approaches were the most efficient control measure for the COVID-19 pandemic. Pandemic preparedness also requires a fact-based discussion both in the public and in parliaments to settle the conflict between individual freedom and necessary restriction during a pandemic. Mature and educated citizens are needed not only for coping with pandemics but also for creating stress-resistant democratic societies. Learned scientific societies should contribute to this discussion.","PeriodicalId":516860,"journal":{"name":"Sustainable microbiology","volume":"14 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141651366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the microbiological safety and antimicrobial resistance (AMR) profiles of 520 RTE seafood samples collected from Bayelsa, Nigeria. Escherichia coli identification was conducted using culture-based and polymerase chain reaction (PCR) methods. The isolates were further characterized using standard bacteriological techniques. Polymerase chain reaction screening was employed to detect virulence and resistance genes. Of the processed RTE seafood samples assessed, 12.1% tested positive for E. coli. Extended-spectrum beta-lactamase (ESBL)-producing E. coli accounted for 2.3% of the samples. Various diarrheagenic determinants were identified, with aggregative adherence regulator-activated island (aaiC) and attaching and effacing (eae) being the most prevalent. Higher AMR levels were observed in ESBL-producing strains. Additionally, extracellular virulence factors, biofilm formation, and hydrophobicity assays revealed diverse pathogenic potentials among the isolates. The detection of beta-lactamase AMR genes, such as blaTEM (15.9%), blaCTX−M−15 (3.2%), and blaCTX−M−1 (1.6%), underscores the genetic mechanisms responsible for resistance in E. coli strains recovered from RTE seafood. These findings underscore the need for thorough monitoring and strict control procedures to ensure the safety of RTE seafood and mitigate the risks associated with AMR in food consumption.","PeriodicalId":516860,"journal":{"name":"Sustainable microbiology","volume":"60 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141651694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is, however, concern that their use and misuse might contribute to the evolution of antimicrobial resistance (AMR). When evaluating the risk associated with biocides, it is important to adopt an objective approach towards the evidence regarding both the benefits of their appropriate deployment as well as potential contribution to AMR. Biocide use should be restricted to applications where there are tangible benefits but also not unnecessarily restricted where genuine benefits can be demonstrated. From the perspective of sustainability, such benefits include the control and prevention of infections in clinical settings with associated reductions in antibiotic use, preservation of a range of products and materials, substantial reduction in infection risk for consumers, hygiene in the community (e.g. in public swimming baths), and microbial control in many facets of industry.

Microbial plastic biodegradation represents an emerging solution to this problem. However, biodegradation studies tend to overlook the fundamental prerequisite of initial surface colonization via biofilm formation. This study had two independent but connected aims relating to plastic surface colonization by microorganisms: to enhance biofilm formation by known plastic degraders, with translational potential for improved plastic degradation, and to isolate microorganisms from microplastic contaminated environments with the ability to colonize plastic surfaces. Planktonic and biofilm responses to diverse carbon and energy sources were investigated over seven days, using Bacillus subtilis 168, Fusarium solani (Martius) Saccardo, Ideonella sakaiensis 201-F6, Pseudomonas putida KT2440 and Rhodococcus ruber C208. This enabled optimal conditions for biofilm formation by each strain to be determined. In parallel, environmental samples containing synthetic or natural polymeric substances (anaerobic digestate, landfill leachate, and microplastic contaminated compost) were incubated with polyethylene and polyethylene terephthalate films, to isolate microorganisms capable of colonizing their surfaces. This yielded eight bacterial isolates from three genera: Bacillus, Lysinibacillus, and Proteus. These genera contain species that have been shown to degrade plastics and other recalcitrant synthetic polymers, demonstrating the success of our approach. This study also suggests that discrete plastic types may create different ecological niches which can be exploited by unique bacterial colonizers. Our findings underscore the importance of considering plastic colonization by microbial biofilms in the context of their biodegradation.","PeriodicalId":516860,"journal":{"name":"Sustainable microbiology","volume":" 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141126904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This positive goal extends to the soil quality driving plant growth and disease resistance. In research aimed at identifying the causes of this beneficial action, a common interpretation is that microbes will synthesize metabolites useful to their hosts. This view assumes that important microbial metabolites are exported for use by their hosts. Yet, this seems unlikely for essential metabolites, without a counterpart imported from the plants, as the corresponding syntheses would often involve the consumption of resources without explicit benefit to the microbes. Illustrating this function with the example of Bacilli of the Subtilis clade, we emphasize here that the most direct access to the contents of microbial cells is through cell lysis, a phenomenon often linked to the process of sporulation. This process also releases macromolecules that are digested in the environment, releasing key metabolites such as queuine, an important base analog present in the anticodon of some transfer RNAs. This overlooked importance of cell lysis could also be a major cause of the ubiquitous presence of bacteriophages in microbiota.","PeriodicalId":516860,"journal":{"name":"Sustainable microbiology","volume":"46 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140972899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four hundred RTE food samples were collected from food outlets, and MRSA presence was determined using oxacillin resistance screening agar supplemented with polymyxin B and oxacillin. Polymerase chain reaction confirmed and characterized MRSA isolates for virulence potentials and antimicrobial resistance genes. Out of the 400 samples, 57(14.25%) tested positive for MRSA.

Our results indicated that Proteobacteria (Pseudomonadota) prevailed in all samples followed by Firmicutes (Bacillota) or Bacteroidota (mostly in feces), while fecal communities were richer. Taxonomic distributions at the operational taxonomic unit level in midgut samples revealed differentially abundant fermentative species that prevailed in individuals fed with the innovative diet. Especially Staphylococcus was more abundant in MI samples implying enhancement from ingredients present only in the innovative diet and implying that this feed shapes rather favorable microbiota, which could support the digestion and good growth performance in aquaculture.","PeriodicalId":516860,"journal":{"name":"Sustainable microbiology","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140716522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
