Genus Pseudomonas includes a large number of species that can be encountered in biotechnological processes as well as in the role of serious human or plant pathogens. Pseudomonads easily form biofilms on various types of surfaces. The biofilm phenotype is characterized by an increased resistance to environmental influences including resistance to antibiotics and other disinfectants, causing a number of problems in health care, food industry, and other areas. Considerable attention is therefore paid to the possibilities of eradication/destruction of pseudomonads biofilms both in terms of understanding the mechanisms of biofilm formation and at the level of finding suitable antibiofilm tools applicable in practice. The first part of this review is devoted to an overview of the regulatory mechanisms that are directly or indirectly involved in the formation of biofilm. The most effective approaches to suppressing the formation of biofilm that do not cause the development of resistance are based on the application of substances that interfere with the regulatory molecules or block the appropriate regulatory mechanisms involved in biofilm development by the cells. Pseudomonads biofilm formation is, similar to other microorganisms, a sophisticated process with many regulatory elements. The suppression of this process therefore also requires multiple antibiofilm tools.
假单胞菌属包括大量的物种,这些物种在生物技术过程中以及作为严重的人类或植物病原体时都可能出现。假单胞菌很容易在各种类型的表面上形成生物膜。生物膜表型的特征是对包括抗生素和其他消毒剂在内的环境影响的抵抗力增强,这在医疗保健、食品工业和其他领域引发了许多问题。因此,无论是在理解生物膜形成机制方面,还是在寻找适用于实践的合适抗生物膜工具方面,人们都相当关注根除/破坏假单胞菌生物膜的可能性。本综述的第一部分致力于概述直接或间接参与生物膜形成的调控机制。抑制生物膜形成且不会导致耐药性产生的最有效方法是基于应用干扰调节分子或阻断细胞参与生物膜形成的适当调节机制的物质。与其他微生物一样,假单胞菌生物膜的形成是一个具有许多调节元件的复杂过程。因此,抑制这一过程也需要多种抗生物膜工具。
