Conventional microbiology methods used to detect bacteria include multiple cultures and identification processes, so the results of lab work are painstaking and time-consuming. In recent years, more and more tend to use the diagnostic tests which are based on DNA; hence, DNA diagnostic biosensors have been created to perform DNA identification better. In this study, GUS and hpt genes were used ...

The production of β-lactamase enzymes is the main mechanism of resistance to β-lactam antibiotics in gramnegative bacilli. Therefore, it is important to identify the β-lactamases-producing bacteria for the treatment of caused infections. This article aimed to review the recent literature and guidelines regarding phenotypic detection of β-lactamases in common gram-negative bacilli in clinical sa...
