Comparative Studies of the Spectrophotometric and Microbiological Assay Methods Used for the Determination of Ampicillin Levels in Ampicillin/Cloxacillin Combinations [PDF]
, 2011 : The spectrophotometric and microbiological assay methods used for the determination of ampicillin levels in ampicillin/cloxacillin combinations were compared. A total of 24 samples of ampicillin/cloxacillin suspensions from 8 batches and 3 companies (B

DNA Replication Errors Drive Genome‐Wide Small Inverted Triplication Dynamics
Advanced Science, EarlyView.This study provides insight into the dynamic equilibrium mechanism of a novel structural variant, small inverted triplication (SIT), which is generated by misalignment of the 3’ flap generated under DNA replication stress with palindromic sequence. Alternatively, the end sequence may fold back on itself to form an inverted fragment.

Advanced Science, EarlyView.High‐throughput single‐cell analysis of resuscitating bacteria reveals a starvation‐history‐dependent transiently tolerant subpopulation that survives β$\beta$‐lactam exposure by temporarily reducing growth. Distinct from classical persisters, these actively growing yet dynamically modulated cells dominate survival across clinically relevant antibiotic

Resistance of Ampicillin, Ceftazidime, and Cefotaxime in Poultry’s Escherichia coli
, 2023 Beta-lactam antibiotics are important antibiotics that are widely used in the field of human and animal health. Ampicillin resistance has been widely reported. Another increase in resistance is 3rd generation cephalosporins. The purpose of this study was

Advanced Science, EarlyView.A biohybrid nanorobot integrating lytic bacteriophage N4 with Pd nanozymes is developed for targeted eradication of multidrug‐resistant E. coli biofilms. Synergistic bacterial lysis and ROS‐mediated oxidation enable simultaneous biofilm removal and antibiotic resistance genes degradation, maintaining high efficacy in complex wastewater environments ...
