This book details the basic bacteriological and molecular techniques applied to Streptococcus pneumoniae. Divided into four chapters, the first covers culture, identification (biochemical and molecular) and preservation techniques. The second chapter is devoted to serotyping. Then, the third chapter is dedicated to molecular typing (PFGE and MLST), and finally, the study of antibiotic resistance is detailed in the last chapter.We hope this book will inspire new discoveries and promote a better understanding of this bacterial organism. Happy reading and research!
