When a group of microbiologists gathered to discuss how to write this book, one of the future authors, a young microbiologist, asked me a question. Would it not seem strange and unusual to call it “Interesting microbiology”? Maybe it is better to call it “Popular” or “Public” microbiology, or something like that? I, remember, even offended for my science . Allow, I said , Why mathematics or physics can be fun And microbiology you refuse it? And is there anything not interesting in our science? Is it possible to ever stop being surprised by those microscopic miracles , which we study every day? Yes, experiments with viruses , Which you told me today...................................... not wonderful and not entertaining? All sighed. So it is so, the young opponent answered me, but how to write about it all entertainingly? Let's try it, we decided everything: our judges will be readers . Now the book is in front of you, dear readers, and you have to decide how successful it was.
