Master the basics of bacterial identification with a classic lab manual. This edition presents a practical, step‑by‑step approach to recognizing bacterial forms, focusing on identification over theory and classification.
This book collects systematic tables and clear descriptions to help teachers and students place a culture in the hands of a learner. It emphasizes practical methods for observing and identifying bacteria in the lab, with guidance on preparing and staining specimens for reliable results.

Preliminary to studies on the bacterial flora of cultivated soils, the writer undertook an arrangement of the several hundred species of bacteria already described, with the view of identifying the forms isolated, or at least of determining whether they were new to science. The labor involved in this arrangement has been so great that it was decided to embody the results in the present form that others might have the advantage of them. The writer does not claim that the system of arrangement is perfect or not open to criticism. The best use only could be made of the facts and material available. The present tables serve, therefore, only for purposes of identification, and not necessarily for those of classification. For this reason the present book has been termed a Manual of Determinative, rather than one of Systematic, Bacteriology. To the student working in the laboratory the determination of unknown bacteria has been almost impossible, except with the expenditure of an amount of labor which was impracticable. With the use of the present manual it is believed that the teacher can place a given culture in the hands of his pupil and expect him to determine it, as is done with other organic forms. It is therefore hoped that the present work will serve a useful purpose as a laboratory manual. The chapter on morphology has been appended in order to make clearer the system of classification into orders and genera.

Paperback. Etat : New. Print on Demand. This book delves into the fascinating world of bacteria, offering a comprehensive guide to their identification and classification. The author, a renowned bacteriologist, recognized the challenges faced by scientists in accurately identifying these microscopic organisms and developed a detailed system for their classification based on their morphology and biochemical functions. Through meticulous observation and experimentation, the author unveils the intricate structure of bacterial cells, their diverse forms and groupings, and their remarkable ability to adapt and thrive in various environments. The book explores the processes of cell division, spore formation, and the production of specialized structures like flagella and gonidia. Moreover, it emphasizes the importance of studying the chemical functions of bacteria, such as their ability to produce indol and phenol, reduce nitrates to nitrites, and ferment carbohydrates. By understanding these biochemical processes, scientists can gain valuable insights into the role of bacteria in various ecosystems and their potential impact on human health and disease. Ultimately, this book serves as a testament to the ingenuity and dedication of early bacteriologists in unraveling the mysteries of the microbial world. Their groundbreaking work laid the foundation for our present-day understanding of these ubiquitous and influential organisms.
