The present book on "Prevalence of resistance amongst negative bacilli against quinolones" is very in formative for the M.Sc. Medical Microbiologist and B.Sc., M.Sc., Ph.D. students who can work in microbiology laboratories. This book included the resistance study of seven novel fluoroquinolones on some gram negative bacilli and concluded that isolates were highly resistance to first and second generation of fluoroquinolones probably indicating occurence of cross resistance.
