Most plasmids lack genes for conjugation and characterized origins of transfer (oriT), which has hampered our understanding of plasmid mobility. Here we used bioinformatic analyses to characterize occurrences of known oriT families across 38,057 plasmids, confirming that most conjugative and mobilizable plasmids lack identifiable oriTs. Recognizable oriT sequences tend to be intergenic, upstream of relaxase genes and specifically associated with relaxase types. We used these criteria to develop a computational method to search for and identify 21 additional families of oriT-containing sequences in plasmids from the pathogens Escherichia coli, Klebsiella pneumoniae and Acinetobacter baumannii. Sequence analyses found 3,072 occurrences of these oriT-containing sequences across 2,976 plasmids, many of which encoded antimicrobial resistance genes. Six candidate oriT-containing sequences were validated experimentally and were shown to facilitate conjugation in E. coli. These findings expand our understanding of plasmid mobility. Characterization of known plasmid oriT features facilitates identification of 21 oriT-containing sequence families which, alongside candidate sequence validation, expands our understanding of plasmid mobility, including plasmids encoding antibiotic resistance.","PeriodicalId":18992,"journal":{"name":"Nature Microbiology","volume":"9 12","pages":"3240-3253"},"PeriodicalIF":20.5,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142597656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phages employ counterstrategies to evade host immunity, but anti-Dnd immunity has not been characterized. Here we report an immune evasion protein encoded by the Salmonella phage JSS1 that contributes to subverting Dnd and other defence systems. Using quantitative proteomic and phosphoproteomic analyses, we show that the protein JSS1_004 employs N-terminal Ser/Thr/Tyr protein kinase activity to catalyse the multisite phosphorylation of host DndFGH. Notably, JSS1_004 also phosphorylates other bacterial immune systems to varying degrees, including CRISPR‒Cas, QatABCD, SIR2+HerA and DUF4297+HerA. Given that JSS1_004 and its homologues are widespread in phylogenetically diverse phages, we suggest that this strategy constitutes a family of immune evasion proteins that increases the chances of phage proliferation even when a host deploys multiple defence systems. An immune evasion protein encoded by the Salmonella phage JSS1 subverts multiple host antiphage defence systems using protein kinase activity.","PeriodicalId":18992,"journal":{"name":"Nature Microbiology","volume":"9 12","pages":"3226-3239"},"PeriodicalIF":20.5,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies on Apicomplexa motile morphotypes, including the T. gondii tachyzoite, have identified a cortical actin–myosin motor system that drives the rearward translocation of transmembrane adhesins, thus powering forward movement. However, this model is currently questioned. Here, combining micropatterning and tunable surface chemistry (to edit parasite surface ligands) with flow force and live or super-resolution imaging, we show that tachyzoites build only one apical anchoring contact with the substrate, over which it slides. Furthermore, we show that glycosaminoglycan–parasite interactions are sufficient to promote such force-productive contact and find that the apicobasal flow is set up independent of adhesin release and surface interactions. These findings should enable further characterization of the molecular functions at the T. gondii–substrate mechanosensitive interface and their comparison across apicomplexans. Live imaging, combined with micropatterning and tunable surface chemistry, reveals the adhesive strategy evolved by Toxoplasma gondii for helical gliding.","PeriodicalId":18992,"journal":{"name":"Nature Microbiology","volume":"9 12","pages":"3148-3164"},"PeriodicalIF":20.5,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142574466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We experimentally established a dataset of interactions between 403 diverse Escherichia strains and 96 phages. Most interactions are explained by adsorption factors as opposed to antiphage systems which play a marginal role. We trained predictive algorithms and pinpoint poorly predicted interactions to direct future research efforts. Finally, we established a pipeline to recommend tailored phage cocktails, demonstrating efficiency on 100 pathogenic E. coli isolates. This work provides quantitative insights into phage–host specificity and supports the use of predictive algorithms in phage therapy.

Blood samples from three groups—recovered individuals, those with prolonged PASC-CVS and SARS-CoV-2-negative individuals—revealed that those with PASC-CVS had a blood signature linked to inflammation. Trace-level pro-inflammatory cytokines were detected in the plasma from donors with PASC-CVS 18 months post infection using nanotechnology.

Plasma proteomics also demonstrated higher levels of complement and coagulation proteins in the plasma from patients with PASC-CVS.

We used experimental evolution and mathematical modelling of Candida auris population dynamics during cyclic and combined drug exposures and found that especially CS-based drug cycling can effectively prevent the emergence of drug resistance. In addition, we found that a CS-based treatment switch can actively select against or eradicate resistant sub-populations, highlighting the potential to consider CS in therapeutic decision-making upon resistance detection.
