Antimicrobial resistance in clinical <I>Escherichia coli</I> isolates obtained from animals by M. N. Isakova, O. V. Sokolova, N. A. Bezborodova, A. S. Krivonogova, A. G. Isaeva, V. D. Zubareva

“…It was found that Escherichia coli clinical isolates are sensitive to third-generation cephalosporins and fluoroquinolone antimicrobials. However, since 28.46% of cultures demonstrate intermediate resistance to third-generation cephalosporins and 49.02% of Escherichia coli DNA samples isolated from mammal gland secretions had blaDHA gene associated with resistance to this group of antimicrobials, these antimicrobials could be hardly recommended as antibiotics of choice. …”

The Threat of the Emergence of Antimicrobial-Resistant Gram-Positive Pathogens in Canada by Donald E Low, Barbara M Willey, Allison J McGeer

“…In some states, penicillin -resistant Streptococcus pneumoniae in the community selling has gone from rates of less than 5% in 1988 to 50% in 1994, including: resistance to third-generation cephalosporins and carbapenems. Although these same pathogens have now been identified in Canada, we may still be in a position to limit or prevent their spread.…”

The Mechanisms of Catalysis by Metallo 𝛽-Lactamases by Michael I. Page, Adriana Badarau

“…Class B 𝛽-lactamases or metallo-𝛽-lactamases (MBLs) require zinc ions to catalyse the hydrolysis of 𝛽-lactam antibiotics such as penicillins, cephalosporins, carbapenems, and cephamycins. There are no clinically useful inhibitors against MBLs which are responsible for the resistance of some bacteria to antibiotics. …”
