This is the fifth edition of a general introduction for students of medical sciences. The previous edition was published in 1992. The 10-chapter book describes various concepts in microbiology and includes many study problems and questions. The textbook provides content for an introductory course on microbiology. The book includes chapters on chemistry, pathogenicity, and epidemiology. The questions provide a self-evaluation mechanism for the student. The author has achieved these worthwhile objectives. The book is written as an introductory text for the healthcare student. I agree with this as the audience. The reading level and content seem appropriate for these students. The authors have many years of experience teaching this type of course at the community college level. The list of academic accomplishments of the authors is impressive. Illustrations are very important in a book on microbiology; and this book is well illustrated. This book includes a short list of current suggested readings as opposed to specific references. The table of contents and index are comprehensive. The thought-provoking problems and questions found at the end of each chapter are the best features of the book. This comprehensive textbook could serve as a useful guide to the beginning healthcare student taking a microbiology class. Bookstores on college campuses offering introductory courses on microbiology should have this available. The book would make a useful reference for any medical library.
