S. Typhimurium ATCC 19585 (STWT) was exposed to ciprofloxacin, gentamicin, kanamycin, and tetracycline to induce antibiotic resistance, respectively, assigned as STCIP, STGEN, STKAN, and STTET. The susceptibilities of the antibiotic-induced resistant mutants to cefotaxime, chloramphenicol, ciprofloxacin, gentamicin, kanamycin, polymyxin B, streptomycin, tetracycline, and tobramycin were determined in the absence and presence of CCCP and PA\u03b2N. STCIP showed the cross-resistance to tetracycline and collateral sensitivity to gentamicin (1\/2 fold) and kanamycin (1\/4 fold). STTET was also cross-resistant to ciprofloxacin (128-fold) and collateral sensitive to gentamicin (1\/4-fold) and kanamycin (1\/8-fold). The cross-resistance and collateral sensitivity of STCIP and STTET were associated with the AcrAB-TolC efflux pump and outer membrane porin proteins (OmpC). This study provides new insight into the collateral sensitivity phenomenon, which can be used for designing effective antibiotic treatment regimens to control antibiotic-resistant bacteria.<\/jats:p>","DOI":"10.3390\/antibiotics12081335","type":"journal-article","created":{"date-parts":[[2023,8,18]],"date-time":"2023-08-18T10:14:38Z","timestamp":1692353678000},"page":"1335","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Ciprofloxacin and Tetracycline Resistance Cause Collateral Sensitivity to Aminoglycosides in Salmonella Typhimurium"],"prefix":"10.3390","volume":"12","author":[{"given":"Mahadi","family":"Hasan","sequence":"first","affiliation":[{"name":"Department of Biomedical Science, Kangwon National University, Chuncheon 24341, Gangwon, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7676-0493","authenticated-orcid":false,"given":"Jun","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Food Science and Engineering, Qingdao Agricultural University, Qingdao 266109, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9341-009X","authenticated-orcid":false,"given":"Juhee","family":"Ahn","sequence":"additional","affiliation":[{"name":"Department of Biomedical Science, Kangwon National University, Chuncheon 24341, Gangwon, Republic of Korea"},{"name":"Institute of Bioscience and Biotechnology, Kangwon National University, Chuncheon 24341, Gangwon, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"284","DOI":"10.1080\/21553769.2015.1051243","article-title":"Salmonella: A review on pathogenesis, epidemiology and antibiotic resistance","volume":"8","author":"Eng","year":"2015","journal-title":"Front.
