CAP exerts its effects by generating reactive oxygen and nitrogen species (RONS), but its comparative efficacy against antimicrobial drugs requires further exploration.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Aim.<\/jats:bold> To evaluate the antimicrobial efficacy of CAP in inactivating multidrug-resistant <jats:italic>Escherichia coli<\/jats:italic> (ATCC BAA-2469), <jats:italic>Staphylococcus aureus<\/jats:italic> (MTCC 96) and <jats:italic>Candida albicans<\/jats:italic> (MTCC 227) and to compare its effectiveness with standard antimicrobial drugs.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Methodology.<\/jats:bold> CAP, produced by an indigenously developed dielectric barrier discharge (DBD) setup comprising a quartz-glass-covered high-voltage electrode and a grounded stainless steel mesh electrode, was used to treat three pathogenic samples with varying treatment times (0\u201360\u2009s). The zone of inhibition (ZoI; zone where microbes cannot grow) induced by CAP was compared with the ZoI of selected antimicrobial drugs (5\u2013300 mcg). Scanning electron microscopy (SEM) analysed morphological changes, while optical emission spectroscopy (OES) detected RONS generated during treatment. Growth curve analysis assessed CAP\u2019s impact on microbial growth, and statistical analysis compared CAP-induced ZoI with drug-induced ZoI.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Results.<\/jats:bold> CAP treatment produced substantial ZoI against <jats:italic>E. coli<\/jats:italic>, <jats:italic>S. aureus<\/jats:italic> and <jats:italic>C. albicans,<\/jats:italic> with the largest ZoI (1194\u00b135.35\u2009mm\u00b2) in <jats:italic>C. albicans<\/jats:italic> after 60\u2009s. DBD\u2013CAP showed equivalent or superior efficacy compared with selected antimicrobial drugs based on ZoI comparisons. SEM revealed extensive cellular damage in all three pathogens, with visible morphological disruption within 60\u2009s. Growth curve analysis showed a significant delay in microbial proliferation with increasing CAP exposure, effectively inhibiting growth over 24\u2009h. OES confirmed the presence of RONS-related molecular bands [N<jats:sub>2<\/jats:sub>(C\u2013B), N<jats:sub>2<\/jats:sub>\n                  <jats:sup>+<\/jats:sup>(B\u2013X) and OH(A\u2013X)] and atomic O lines in the CAP.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Conclusion.<\/jats:bold> CAP treatment exhibits equivalent or superior antimicrobial activity compared to selected antimicrobial drugs. CAP treatment exerts effects by inactivating pathogens, disintegrating cellular morphology and delaying microbial growth. These findings highlight CAP as a promising alternative to prolonged treatments, addressing antimicrobial resistance and advancing clinical strategies.<\/jats:p>","DOI":"10.1099\/jmm.0.001965","type":"journal-article","created":{"date-parts":[[2025,1,29]],"date-time":"2025-01-29T17:26:07Z","timestamp":1738171567000},"source":"Crossref","is-referenced-by-count":7,"title":["Inactivation of Candida albicans, Staphylococcus aureus and multidrug-resistant Escherichia coli with dielectric barrier discharged cold atmospheric plasma: a comparative study with antimicrobial drugs"],"prefix":"10.1099","volume":"74","author":[{"given":"Punam","family":"Talukdar","sequence":"first","affiliation":[{"name":"Academy of Scientific and Innovative Research (AcSIR), Ghaziabad 201002, India"},{"name":"Institute of Advanced Study in Science and Technology (IASST), Guwahati 781035, Assam, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reetesh Borpatra","family":"Gohain","sequence":"additional","affiliation":[{"name":"Academy of Scientific and Innovative Research (AcSIR), Ghaziabad 201002, India"},{"name":"Institute of Advanced Study in Science and Technology (IASST), Guwahati 781035, Assam, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pranami","family":"Bharadwaj","sequence":"additional","affiliation":[{"name":"Academy of Scientific and Innovative Research (AcSIR), Ghaziabad 201002, India"},{"name":"Institute of Advanced Study in Science and Technology (IASST), Guwahati 781035, Assam, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Debajit","family":"Thakur","sequence":"additional","affiliation":[{"name":"Academy of Scientific and Innovative Research (AcSIR), Ghaziabad 201002, India"},{"name":"Institute of Advanced Study in Science and Technology (IASST), Guwahati 781035, Assam, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9361-8261","authenticated-orcid":false,"given":"Subir","family":"Biswas","sequence":"additional","affiliation":[{"name":"Institute of Advanced Study in Science and Technology (IASST), Guwahati 781035, Assam, India"},{"name":"Academy of Scientific and Innovative Research (AcSIR), Ghaziabad 201002, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"345","reference":[{"key":"R1","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2010.00134"},{"key":"R2","doi-asserted-by":"publisher","DOI":"10.3390\/antibiotics8020045"},{"key":"R3","doi-asserted-by":"publisher","DOI":"10.1109\/TRPMS.2023.3235358"},{"key":"R4","doi-asserted-by":"publisher","DOI":"10.1038\/ja.2017.124"},{"key":"R5","doi-asserted-by":"publisher","DOI":"10.1002\/mbo3.1260"},{"key":"R6","doi-asserted-by":"publisher","DOI":"10.1016\/j.bcp.2016.09.025"},{"key":"R7","article-title":"Global shortage of innovative antibiotics fuels emergence and spread of drug-resistance"},{"key":"R8","doi-asserted-by":"publisher","DOI":"10.1007\/s00284-022-03029-7"},{"key":"R9","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijantimicag.2014.04.020"},{"key":"R10","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0138209"},{"key":"R11","doi-asserted-by":"publisher","DOI":"10.1063\/1.3530434"},{"key":"R12","doi-asserted-by":"publisher","DOI":"10.12968\/jowc.2018.27.Sup9.S4"},{"key":"R13","doi-asserted-by":"publisher","DOI":"10.1109\/TRPMS.2021.3135118"},{"key":"R14","article-title":"Introduction to plasma physics and controlled fusion.
