Microbial Biotechnology, Volume 13, Issue 3, Page 669-682, May 2020., 2020 Antibiotic treatment leads to expansion of facultative anaerobic Escherichia spp. (proteobacteria) in calves, a signature of imbalanced microbiota, dysbiosis. This in turn enhances a risk of the growth of bacteria that carry highly mobile clinically relevant resistances that can be transmitted to humans. Summary In agriculture, antibiotics are used for

Molecular Characterization of an Atypical IncX3 Plasmid pKPC-NY79 Carrying blaKPC-2 in a Klebsiella pneumoniae [PDF]
, 2013 The IncX family of plasmids has recently been expanded to include at least four subtypes, IncX1-IncX4. The revised classification provides an opportunity for improving our understanding of the sequence diversity of the IncX plasmids and the resistance ...

Serum bactericidal activity of colistin and azidothymidine combinations against mcr-1 positive colistin-resistant Escherichia coli. [PDF]
, 2018 To examine the serum bactericidal activity of colistin-sulphate (CS) and azidothymidine (AZT) combinations, time-kill curves were performed in native and heat-inactivated human serum with five colistin-resistant and four colistin-susceptible Gram ...

Prevalence and characterization of hybrid blaCTX-M among Escherichia coli isolates from livestock and other animals [PDF]
, 2015 This study investigated 248 extended-spectrum β-lactamase-producing Escherichia coli isolates from 2012 to 2013 for hybrid blaCTX-M genes. blaCTX-M genes were detected in 228 isolates of which 14 isolates were hybrid blaCTX-M positive (6 blaCTX-M-123, 6 ...
