CRISPR/cas9 cassette targeting Escherichia coli blaCTX-M specific gene of mastitis cow milk origin can alter the antibiotic resistant phenotype for cefotaxime.

Abstract excerpt

CTX-M beta-lactamases are one of the most important extended spectrum beta-lactamase (ESBL) resistance enzymes found in E. coli. In the present study, 59% of E. coli isolates from mastitis cow milk were reported to be positive for ESBL types. The prevalence of beta-lactam (β-lactam) antibiotic resistance was reported to be 84%, 72.7%, 52.27%, 50%, and 45.4% for cefotaxime, cefepime, cefuroxime, oxacillin, and...
