Currently, mixed infections of these two pathogens are prevalent in livestock production; thus, establishing a molecular diagnostic method for the simultaneous detection and analysis of brucellosis and tuberculosis is crucial for the prevention and control of these diseases. By utilizing conserved regions within the genomes of\n                    <jats:italic>Brucella<\/jats:italic>\n                    and\n                    <jats:italic>Mycobacterium<\/jats:italic>\n                    , we designed specific primers and probes. After optimizing the developed qPCR assay conditions, we determined the lower limit of detection to be ten copies\/ \u03bcL. Cross-testing with other bovine-derived pathogens demonstrated no cross-reactivity. Repeatability tests indicated that the coefficient of variation for the developed qPCR assay was less than 4.10% both within and between batches. We employed both the developed qPCR assay and a commercial qPCR assay to analyze sixty mixed infection samples of\n                    <jats:italic>Brucella<\/jats:italic>\n                    and\n                    <jats:italic>Mycobacterium<\/jats:italic>\n                    from various regions. The results revealed positivity rates of 100% and 96.67% for\n                    <jats:italic>Brucella<\/jats:italic>\n                    , and 100% and 95.00% for\n                    <jats:italic>Mycobacterium<\/jats:italic>\n                    , respectively. These findings indicate that a highly sensitive, specific, reproducible, and versatile qPCR method has been developed for the simultaneous quantitative detection of\n                    <jats:italic>Brucella<\/jats:italic>\n                    and\n                    <jats:italic>Mycobacterium<\/jats:italic>\n                    , which can be applied in studying the pathogenesis and epidemiology of these pathogens.\n                  <\/jats:p>","DOI":"10.3389\/fmicb.2025.1633809","type":"journal-article","created":{"date-parts":[[2025,9,12]],"date-time":"2025-09-12T05:37:01Z","timestamp":1757655421000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Establishment and application of a TaqMan-based quantitative PCR assay for simultaneous detection of bovine Brucella spp. and Mycobacterium spp."],"prefix":"10.3389","volume":"16","author":[{"given":"Shuai","family":"Zhang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiuju","family":"Guo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruixue","family":"Xue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zixin","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenduo","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linlin","family":"Xing","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinhui","family":"Wei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youxiang","family":"Diao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zouran","family":"Lan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,9,12]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"144","DOI":"10.14202\/vetworld.2021.144-154","article-title":"Validation of real-time polymerase chain reaction versus conventional polymerase chain reaction for diagnosis of brucellosis in cattle sera","volume":"14","author":"Abdel-Hamid","year":"2021","journal-title":"Vet World."},{"key":"B2","doi-asserted-by":"publisher","first-page":"8812898","DOI":"10.1155\/2021\/8812898","article-title":"Does Mycobacterium spp. Tuberculosis var. bovis survival in the environment confound bovine tuberculosis control and eradication?
