This study evaluated AMR in 128 isolates from Shandong, Hebei and Inner Mongolia using the broth microdilution method. Results showed high sensitivity to most antibiotics (e.g. 100% resistance to penicillin, ceftiofur, amoxicillin, cefquinome and vancomycin) but significant resistance to tetracycline (80.7%) and daptomycin (99.3%). Inner Mongolia isolates exhibited higher resistance and mimimum inhibitory concentrations (MIC) values, reflecting regional antibiotic usage differences, guiding mastitis treatment and antibiotic stewardship in China's dairy industry.\n                  <\/jats:p>","DOI":"10.1017\/s0022029925101283","type":"journal-article","created":{"date-parts":[[2026,3,27]],"date-time":"2026-03-27T09:36:27Z","timestamp":1774604187000},"page":"265-267","source":"Crossref","is-referenced-by-count":0,"title":["Research communication: Regional variation in antimicrobial resistance of\n                    <i>Streptococcus agalactiae<\/i>\n                    isolated from bovine mastitis in major dairy-producing provinces of northern China"],"prefix":"10.1017","volume":"93","author":[{"given":"Jieyan","family":"Yang","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04dpa3g90","id-type":"ROR","asserted-by":"publisher"}],"name":"Yunnan Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Liu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04dpa3g90","id-type":"ROR","asserted-by":"publisher"}],"name":"Yunnan Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang","family":"Liu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04dpa3g90","id-type":"ROR","asserted-by":"publisher"}],"name":"Yunnan Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sihong","family":"Tao","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04dpa3g90","id-type":"ROR","asserted-by":"publisher"}],"name":"Yunnan Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Wei","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04dpa3g90","id-type":"ROR","asserted-by":"publisher"}],"name":"Yunnan Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingfeng","family":"Ji","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04dpa3g90","id-type":"ROR","asserted-by":"publisher"}],"name":"Yunnan Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haodong","family":"Li","sequence":"additional","affiliation":[{"name":"Yunnan Province Sheep Breeding Promotion Center"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feiyan","family":"Dai","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04dpa3g90","id-type":"ROR","asserted-by":"publisher"}],"name":"Yunnan Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao","family":"Xiao","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04dpa3g90","id-type":"ROR","asserted-by":"publisher"}],"name":"Yunnan Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolong","family":"Gu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04dpa3g90","id-type":"ROR","asserted-by":"publisher"}],"name":"Yunnan Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Limei","family":"Zhang","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04dpa3g90","id-type":"ROR","asserted-by":"publisher"}],"name":"Yunnan Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weijie","family":"Qu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04dpa3g90","id-type":"ROR","asserted-by":"publisher"}],"name":"Yunnan Agricultural University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,3,27]]},"reference":[{"key":"S0022029925101283_ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.micpath.2019.03.035"},{"key":"S0022029925101283_ref18","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0067755"},{"key":"S0022029925101283_ref17","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0199561"},{"key":"S0022029925101283_ref7","volume-title":"Performance Standards for Antimicrobial Susceptibility Testing, CLSI Document.
