Phylogenetic analysis. Amino acid sequences of 17 class A β-lactamases were retrieved from the Beta- Lactamase DataBase (BLDB, http://bldb.eu/), and were utilized for the phylogenetic analysis. Sequences were aligned using the program Clustal W31. A maximum-likelihood tree ...
BlaI is a repressor of BlaZ, the beta-lactamase responsible for penicillin resistance in Staphylococcus aureus. Through screening a transposon library in S. aureus Newman for susceptibility to cathelicidin antimicrobial peptide, we discovered BlaI as a novel cathelicidin resistance factor. Additionally, ...

beta-lactamase Enzyme (penicillin amido-beta-lactam hydrolase, EC 3.5.2.6, 377aa in E. coli) produced by some bacteria that makes them resistant to beta-lactam antibiotics. Competitively inhibited by clavulanic acid. Extended-spectrum beta lactamases (ESBLs) will degrade the ‘extended spectrum cep...

The ESBL genes blaSHV-12, blaSHV-31, and blaCTX-M-15, and the chromosome-encoded SHV-type beta-lactamase capable of hydrolyzing imipenem were detected in Brazil for the first time. The analysis of the enterobacterial repetitive intergenic consensus-PCR band patterns revealed a high rate of ...
Additionally, mastitis-causing coliforms often carry AMR genes akin to those found in hospital-acquired strains, notably the extended-spectrum beta-lactamase genes. This raises concerns regarding the potential transmission of resistant bacteria and AMR from mastitis cases in dairy ...
