Rapid identification and enumeration of bacteria are critical, given the surge of antibiotic-
resistance, global exchange of food products, and the use of bacteria for bioremediation …

The microbial colony growth is driven by the activity of the cells located on the edges of the
colony. However, this process is not visible unless specific staining or cross-sectioning of the …

Rapid identification of effective antibiotic treatment is crucial for increasing patient survival
and preventing the formation of new antibiotic-resistant bacteria due to preventative …

Prior research has indicated the feasibility of assessing growth—associated activity in
bacterial colonies through the application of laser speckle imaging techniques. A subpixel …

The extensive use of quaternary ammonium compounds (QACs) has raised concerns
regarding their environmental fate and potential risks to the ecosystem. As sensitive …

The antimicrobial susceptibility test (AST) plays a crucial role in selecting appropriate
antibiotics for the treatment of bacterial infections in patients. The diffusion disk method is …

Our previous studies have shown that it is possible to determine the growth activity of a
microbial colony by laser speckle imaging techniques. A sub-pixel correlation method was …

Phenotypic resistance tests eg, disc diffusion method require 16–24 h to obtain the results,
while the PCR tests provide only genotypic type of antibacterial resistance. New methods …

The laser speckle imaging technique with sub-pixel correlation analysis allows to identify
changes in the sterile zone radius, and makes it possible to predict these changes …
