Abscess fluid from a convenience sample of clinical cases was cultured. Isolated bacteria were identified using matrix-assisted laser desorption\/ionization time-of-flight (MALDI-TOF) mass spectrometry or 16s rRNA gene sequencing. Antimicrobial susceptibility profiling was performed on isolates when a bacterial species was identified from \u22655 samples.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Fifty of the 54 samples were polymicrobial. Trueperella pyogenes (22\/54), Streptococcus uberis (16\/54), and Bacteroides pyogenes (14\/54) were the most commonly isolated bacteria. Eighty-one of 96 tested isolates were resistant to at least 1 antimicrobial; multidrug resistance was identified in 37\/96 isolates. Oxytetracycline (50\/96), tylosin (40\/96), and florfenicol (37\/96) resistance was commonly identified. Resistance to ceftiofur (5\/96) was rare.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions and Clinical Importance<\/jats:title>\n                    <jats:p>Septic processes of the foot in these adult beef cattle frequently were polymicrobial. Most of the isolated bacteria were resistant to at least 1 antimicrobial with over one-third being multidrug resistant. Although simple sole abscesses do not require antimicrobial treatment, deep septic processes of the foot often are treated with antimicrobials. Culture and susceptibility of deep septic lesions may guide judicious antimicrobial usage.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jvim.16645","type":"journal-article","created":{"date-parts":[[2023,2,11]],"date-time":"2023-02-11T06:33:30Z","timestamp":1676097210000},"page":"757-765","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Bacterial culture and susceptibility of samples taken from septic foot lesions of adult beef cattle"],"prefix":"10.1093","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3807-4657","authenticated-orcid":false,"given":"Kelsey E.","family":"Walker","sequence":"first","affiliation":[{"name":"University of Missouri Department of Veterinary Medicine and Surgery, , Columbia, Missouri,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John R.","family":"Middleton","sequence":"additional","affiliation":[{"name":"University of Missouri Department of Veterinary Medicine and Surgery, , Columbia, Missouri,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamara","family":"Gull","sequence":"additional","affiliation":[{"name":"University of Missouri Department of Veterinary Pathobiology, , Columbia, Missouri,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Craig A.","family":"Payne","sequence":"additional","affiliation":[{"name":"University of Missouri Extension, University of Missouri , Columbia, Missouri,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3363-5961","authenticated-orcid":false,"given":"Pamela R.
