The upregulation of efflux pumps is a particularly concerning mechanism of resistance acquisition as, in many instances, a single point mutation can simultaneously provide resistance to a range of antimicrobials and biocides. The current study investigated mutations in <i>oqxR</i>, which encodes a negative regulator of the RND-family efflux pump genes, <i>oqxAB</i>, natively found in the chromosome of <i>K. pneumoniae</i>. Resistant mutants in four <i>K. pneumoniae</i> strains (KP6870155, NTUH-K2044, SGH10, and ATCC43816) were selected from single exposures to 30 µg/mL chloramphenicol and 12 mutants were selected for whole genome sequencing to identify mutations associated with resistance. Resistant mutants generated by single exposures to chloramphenicol, tetracycline, or ciprofloxacin at ≥4 X MIC were replica plated onto all three antibiotics to observe simultaneous cross-resistance to all compounds, indicative of a multidrug resistance phenotype. A variety of novel mutations, including single point mutations, deletions, and insertions, were found to disrupt <i>oqxR</i> leading to significant and simultaneous increases in resistance to chloramphenicol, tetracycline, and ciprofloxacin. The <i>oqxAB</i>-<i>oqxR</i> locus has been mobilized and dispersed on plasmids in many Enterobacteriaceae species and the diversity of these loci was examined to evaluate the evolutionary pressures acting on these genes. Comparison of the promoter regions of <i>oqxR</i> in plasmid-borne copies of the <i>oqxR-oqxAB</i> operon indicated that some constructs may produce truncated versions of the <i>oqxR</i> transcript, which may impact on <i>oqxAB</i> regulation and expression. In some instances, co-carriage of chromosomal and plasmid encoded <i>oqxAB-oqxR</i> was found in <i>K. pneumoniae</i>, implying that there is selective pressure to maintain and expand the efflux pump. Given that OqxR is a repressor of <i>oqxAB</i>, any mutation affecting its expression or function can lead to multidrug resistance. This is in contrast to antibiotic target site mutations that must occur in limited sequence space to be effective and not impact the fitness of the cell. Therefore, <i>oqxR</i> may act as a simple genetic switch to facilitate resistance via OqxAB mediated efflux.</p>","PeriodicalId":49819,"journal":{"name":"Microbiology-Sgm","volume":"170 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11373524/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142127169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparative genomic analyses identified specific bacteria that showed a discrepancy between the projected Q salvage route and the predicted substrate specificities of the two identified salvage proteins: (1) the distinctive enzyme tRNA guanine-34 transglycosylase (bacterial TGT, or bTGT), responsible for inserting precursor bases into target tRNAs; and (2) queuosine precursor transporter (QPTR), a transporter protein that imports Q precursors. Organisms such as the facultative intracellular pathogen <i>Bartonella henselae</i>, which possess only bTGT and QPTR but lack predicted enzymes for converting preQ<sub>1</sub> to Q, would be expected to salvage the queuine (q) base, mirroring the scenario for the obligate intracellular pathogen <i>Chlamydia trachomatis</i>.

On the one hand, each bottleneck reduces the genetic variation that fuels adaptation.

A theoretical model predicted that the rate of fitness gains should be maximized using ~8-fold dilutions. Here we investigate the impact of repeated bottlenecks on the dynamics of adaptation using numerical simulations and experimental populations of <i>Escherichia coli</i>. Our simulations confirm the model's prediction when populations evolve in a regime where beneficial mutations are rare and waiting times between successful mutations are long. However, more extreme dilutions maximize fitness gains in simulations when beneficial mutations are common and clonal interference prevents most of them from fixing. To examine these predictions, we propagated 48 <i>E. coli</i> populations with 2-, 8-, 100-, and 1000-fold dilutions for 150 days. Adaptation began earlier and fitness gains were greater with 100- and 1000-fold dilutions than with 8-fold dilutions, consistent with the simulations when beneficial mutations are common. However, the selection pressures in the 2-fold treatment were qualitatively different from the other treatments, violating a critical assumption of the model and simulations. Thus, varying the dilution factor during periodic bottlenecks can have multiple effects on the dynamics of adaptation caused by differential losses of diversity, different numbers of generations, and altered selection.</p>","PeriodicalId":49819,"journal":{"name":"Microbiology-Sgm","volume":"170 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11410044/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142299612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
