Solovev A. V., Zimina T. M., Kostko A. F. Perspectives of application of laser light scattering methods in microbiological analysis
The application of laser light scattering methods in microbiological analysis for express identification of microorganisms and testing of their antibiotic resistance is considered. When suspensions of living cultures of microorganisms are exposed to laser light, the dynamic and static characteristics of the scattered light correlate not only with their shape and size, but also with variable parameters of the suspension, the most obvious of which are the change in concentration due to the division of microorganisms and population growth, and lost of viability under the action of antibiotics. These characteristics are manifested both in the angular dependences of the intensity of light scattering and in the kinetics of spatial intensity fluctuations. Live bacterial cells in suspensions form efficiently radiation-dissipating heterogeneous media, which provides a good dynamic range and sensitivity of the analytical method. In the process of division of microorganisms and population growth, an increase in the intensity of scattered light is observed. As a result of the action of the antibiotic on the suspension of microorganisms in the liquid nutrient medium, leading to the termination of fission, a change in the slope in the time dependence of the intensity of scattered light, or a change in the kinetics of local fluctuations in the near field is observed. The ways of miniaturization of light scattering methods for creating the bases of their realization in laboratories-on-a-chip are analyzed. The influence of miniaturization on the analysis speed is investigated. A system of parallel measuring cells with illumination system implemented by split laser beam using a two-dimensional diffraction grid made of anodic aluminum oxide was tested. The experiments were carried out on E. coli M-17 and latex diagnosticum Shigella sonnei models.
