The increase of allergic diseases incidence has been noticed in industrialized countries. The reason for that is sought in increasing environment pollution and hygienisation of life. Diseases including asthma, hay fever, eczema and food allergies have dramatically increased over the last century. Microbiota (intestinal microflora) is a community of microorganisms, mainly bacteria that forms in the human digestive system a complex ecosystem. Recently more and more attention is paid to the connection of intestinal microflora with the occurrence of allergic diseases. Microbiota and the beneficial effects of probiotic bacteria on human health is becoming increasingly important in allergy development. However, the importance of probiotics in the prevention of these diseases has not been proven. It is a necessity to design and carry out thorough and detailed research to confirm significance of treatment with using probiotics strains.
