This initiative exemplifies a course-based undergraduate research experience (CURE) within the microbiology curriculum, which has been shown to promote student engagement and persistence in science, technology, engineering, and mathematics (STEM) disciplines by providing opportunities for authentic scientific inquiry. However, broader adoption of PARE can be limited by its requirement for microbiology specialization and biosafety level protocols. To address these barriers, we developed EcPARE (\n                      <jats:italic toggle=\"yes\">Escherichia coli<\/jats:italic>\n                      [\n                      <jats:italic toggle=\"yes\">E. coli<\/jats:italic>\n                      ]-specific PARE), a culture-free module of PARE that focuses on detecting pathogenic\n                      <jats:italic toggle=\"yes\">E. coli<\/jats:italic>\n                      in water samples using a modified IDEXX Colilert-18 method. Although IDEXX is primarily designed to detect general fecal contamination, our approach demonstrates its utility as a practical tool for screening erythromycin resistance trends in environmental water samples. In this study, undergraduate participants (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 47) conducted hypothesis-driven research, including sample collection, laboratory analyses, data analysis, and interpretation. Our findings revealed strong positive correlations between general coliforms or\n                      <jats:italic toggle=\"yes\">E. coli<\/jats:italic>\n                      counts obtained using the modified IDEXX method and total counts from Luria\u2212Bertani plate cultures, indicating concordance between modified IDEXX and conventional plate count methods in the absence of antibiotic selection. This result validates the scientific rigor of our PARE module. Student outcomes assessed through pre- and post-course surveys indicated substantial increases in students\u2019 confidence in their scientific skills. Notably, underrepresented students reported greater gains in domains related to sense of community and career confidence, suggesting that such CUREs may be especially impactful for supporting the success and retention of diverse student populations.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1128\/jmbe.00173-26","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T13:00:37Z","timestamp":1788958837000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Modified approach for investigating Prevalence of Antibiotic Resistance in the Environment (PARE)\u2014a research project embedded in lecture-based courses"],"prefix":"10.1128","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-3703-7891","authenticated-orcid":true,"given":"Yuwei","family":"Kong","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/046rm7j60","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Civil and Environmental Engineering, University of California, Los Angeles","place":["Los Angeles, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei-Cheng","family":"Hung","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/010kva064","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Chemistry, Southern Oregon University","place":["Ashland, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriane","family":"Jones","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00jkdhd30","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Biological Sciences, Mount Saint Mary's University","place":["Los Angeles, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carol","family":"Bascom-Slack","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/05wvpxv85","id-type":"ROR","asserted-by":"publisher"}],"name":"Tufts University School of Medicine","place":["Boston, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laila","family":"Shaaban","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/046rm7j60","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Civil and Environmental Engineering, University of California, Los Angeles","place":["Los Angeles, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1879-3809","authenticated-orcid":true,"given":"Marisol","family":"Cira","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/046rm7j60","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Civil and Environmental Engineering, University of California, Los Angeles","place":["Los Angeles, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karina","family":"Jimenez","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/046rm7j60","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Civil and Environmental Engineering, University of California, Los Angeles","place":["Los Angeles, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuhui","family":"Zhang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/046rm7j60","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Civil and Environmental Engineering, University of California, Los Angeles","place":["Los Angeles, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5417-1516","authenticated-orcid":true,"given":"Jennifer A.","family":"Jay","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/046rm7j60","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Civil and Environmental Engineering, University of California, Los Angeles","place":["Los Angeles, USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","published-online":{"date-parts":[[2026,9,9]]},"reference":[{"key":"e_1_3_3_2_2","unstructured":"World Health Organization. 2021.
