The book "Microflora of the environment and the human body" under the authorship of N. In. Litusova and his colleagues is a fascinating and deep dive into the world of microbiology, which opens the reader a veil of mystery over how microscopic organisms affect our lives and health. This work will be a real discovery for everyone interested in biology, medicine, ecosystems and their interrelations. The focus of the book is microflora - a set of microorganisms that live both in the environment and in the human body. The authors explore in detail how microbes, which we often perceive as enemies, actually play a key role in maintaining health and well-being. This work not only highlights important aspects of microbiology, but also raises questions about how changes in ecosystems can affect our health. The book will be of interest to a wide range of readers, including students of medical and biological specialties, doctors, researchers, as well as everyone who just wants to better understand how our world works. It is suitable both for young people seeking knowledge, and for more mature readers who want to deepen their knowledge of the microbiome and its significance. The topics raised in the book range from the basics of microbiology to the complex interactions between the microflora and the human body. The authors discuss how microbes can affect the immune system, metabolism, and even mental health. The reader will learn about how environmental ecology, including pollution and climate change, can affect the human microbiome. These issues are becoming particularly urgent in light of current challenges, such as pandemics and the dramatic deterioration of the environmental situation on the planet. Style N. In. Litusova and his colleagues are distinguished by accessibility and clarity, which allows even complex scientific concepts to be presented in an understandable and fascinating form. The authors use many examples from practice, which makes the material more lively and visual. The book is replete with interesting facts and research that will not leave any reader indifferent. In addition, the “Microflora of the environment and the human body” can be a great addition to the library of those who are interested in such works as “Human Microbiome” by Jeremy N . Laver, Microbes: How They Rule Our Lives, Edward O. Wilson or Mary K.'s Miracles of Microbiology Bennett . These books, like Litusov's work, explore important aspects of microbiology and its impact on health and the environment. In conclusion, “The Microflora of the Human Environment and Body” is not just a book about microbes. It is a fascinating journey into a world that we do not see, but which has a huge impact on our existence. Readers who have discovered this book will receive not only new knowledge, but also the opportunity to look at familiar things from a completely different angle. This work will be an important step towards understanding the complex relationships between man and the world, which makes it worthy of attention and discussion in scientific circles and beyond.
