Efficiency of Instrumental Analytical Approaches at the Control of Bacterial Infections in Water, Foods and Feeds

Bacterial agents are those that are pathogenic to humans, plants and animals either by causing infectious diseases or by producing toxins. The review provides the description of some pathogenic bacteria, which are a threat to human health and life and must be strictly controlled in the food, water and the environment. With increasing reports on bioterrorism and other bio-threats, rapid and real time detection methods for various pathogens are warranted. Nowadays is important to develop strategies for early detection and monitoring bacterial agents under any conditions that warrant their recognition, including clinical-based diagnostics and biological warfare applications. The review is devoted to the microorganism’s indication methods. A study of methods of exposure and authentication of biological agents is important design of biosensors and automatic microorganism’s indication. In this study the authors compare the characteristics of the immune biosensors based on the SPR, TIRE, quartz crystal acoustic wave, amperometry, chemiluminescence and on the ISFETs with CeOx gate surface and conclude that they have similar sensitivity. Special attention is paid to biosensors and last tendencies of their creation based on nanostructures such as deposited nanorods, quantum dots and graphene nanostructures. The achievements of the authors in this field and other researching groups all over the world are described.
