A total of 140 <jats:italic>Strep. agalactiae<\/jats:italic> isolates were identified from 12 out of 201 farms in 6 provinces, overall herd prevalence was 18.6% and the MLST analysis showed clonal complexes (CC) 103 and CC 67 were present in these herds with CC 103 predominant, accounting for 97.9%. Isolates were mostly sensitive to the tested antimicrobials: penicillin, ceftiofur, amoxi\/clav, cefquinome, and vancomycin (100%), followed by cefalexin (97.9%), oxacillin (96.4%), enrofloxacin (95.7%), erythromycin (89.3%), and clindamycin (88.6%). Only 19.3 and 0.7% of isolates were sensitive to tetracycline and daptomycin, respectively, and sequence type (ST) 103 was most resistant to antimicrobials. In conclusion, CC 103 was the predominant subgroup of bovine mastitis <jats:italic>Strep. agalactiae<\/jats:italic> in China, and most antimicrobials apart from tetracycline and daptomycin were effective.<\/jats:p>","DOI":"10.1017\/s0022029922000152","type":"journal-article","created":{"date-parts":[[2022,2,28]],"date-time":"2022-02-28T10:42:27Z","timestamp":1646044947000},"page":"75-79","source":"Crossref","is-referenced-by-count":9,"title":["The prevalence, molecular characterization and antimicrobial resistance profiling of <i>Streptococcus agalactiae<\/i> isolated from clinical mastitis cases on large dairy farms in China"],"prefix":"10.1017","volume":"89","author":[{"given":"Kai","family":"Liu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Limei","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolong","family":"Gu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gang","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaoju","family":"Deng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weijie","family":"Qu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2022,2,28]]},"reference":[{"key":"S0022029922000152_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.tvjl.2012.04.020"},{"key":"S0022029922000152_ref2","doi-asserted-by":"publisher","DOI":"10.1128\/AAC.43.4.925"},{"key":"S0022029922000152_ref11","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2017-13363"},{"key":"S0022029922000152_ref12","doi-asserted-by":"publisher","DOI":"10.1016\/j.micpath.2019.03.035"},{"key":"S0022029922000152_ref1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0155621"},{"key":"S0022029922000152_ref9","first-page":"203","article-title":"Update on control of Staphylococcus aureus and Streptococcus agalactiae for management of mastitis","volume":"28","author":"Keefe","year":"2012","journal-title":"Veterinary Clinics of North America: Food Animal Practice"},{"key":"S0022029922000152_ref13","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0199561"},{"key":"S0022029922000152_ref4","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0208990"},{"key":"S0022029922000152_ref8","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2017-12660"},{"key":"S0022029922000152_ref14","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0067755"},{"key":"S0022029922000152_ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.prevetmed.2019.104751"},{"key":"S0022029922000152_ref15","doi-asserted-by":"publisher","DOI":"10.1007\/s10911-011-9236-y"},{"key":"S0022029922000152_ref10","doi-asserted-by":"publisher","DOI":"10.1038\/nm1145"},{"key":"S0022029922000152_ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetmic.2015.12.014"},{"key":"S0022029922000152_ref3","volume-title":"Performance Standards for Antimicrobial Susceptibility Testing, CLSI Document.
