All isolates were susceptible to amoxicillin alone or with clavulanic acid, with MIC values ranging from 0.016 to 0.125 \u03bcg\/mL. Ninety-six percent of isolates were fully sensitive to penicillin G (MIC 0.125\u20130.5 \u03bcg\/mL). All isolates were fully or moderately sensitive to erythromycin (MIC 0.125\u20130.5 \u03bcg\/mL). Most E. rhusiopathiae isolates proved resistant to fluoroquinolones (76.6% of isolates were resistant to enrofloxacin, with MIC values ranging from 0.064 to 32 \u03bcg\/mL, and 68% were resistant to norfloxacin, with MIC values ranging from 0.094 to 96 \u03bcg\/mL), and tetracyclines (61.7% of isolates were resistant to doxycycline, with MIC values ranging from 0.25 to 64 \u03bcg\/mL, and 63.8% were resistant to tetracycline, with MIC values ranging from 0.38 to 256 \u03bcg\/mL). Point mutations in the gyrA gene (responsible for fluoroquinolone resistance) and the presence of the tetM gene (responsible for tetracycline resistance) were noted in most of the resistant isolates. Multidrug resistance, defined as resistance to at least one substance in three or more antimicrobial classes, was not observed.<\/jats:p>","DOI":"10.3390\/antibiotics12081339","type":"journal-article","created":{"date-parts":[[2023,8,21]],"date-time":"2023-08-21T01:33:11Z","timestamp":1692581591000},"page":"1339","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Antimicrobial Resistance of Erysipelothrix rhusiopathiae Strains Isolated from Geese to Antimicrobials Widely Used in Veterinary Medicine"],"prefix":"10.3390","volume":"12","author":[{"given":"Kamila","family":"Bobrek","sequence":"first","affiliation":[{"name":"Department of Epizootiology and Clinic of Birds and Exotic Animals, Faculty of Veterinary Medicine, Wroc\u0142aw University of Environmental and Life Sciences, 50-366 Wroc\u0142aw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrzej","family":"Gawe\u0142","sequence":"additional","affiliation":[{"name":"Department of Epizootiology and Clinic of Birds and Exotic Animals, Faculty of Veterinary Medicine, Wroc\u0142aw University of Environmental and Life Sciences, 50-366 Wroc\u0142aw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"789","DOI":"10.1099\/00222615-48-9-789","article-title":"Erysipelothrix rhusiopathiae: Bacteriology, epidemiology and clinical manifestations of an occupational pathogen","volume":"48","author":"Brooke","year":"1999","journal-title":"J.
