Diagnostics to Pathogenomics of Sexually Transmitted Infections

Comprehensively explores sexually transmitted diseases, from epidemiology, causative pathogens, clinical impact, and immunology, to management strategies utilizing new strategies of genomics and next-generation diagnostic tools

Sexually transmitted infections (STI) are very common worldwide. More than 20 different STIs have been identified, and about 19 million men and women are infected each year in the United States alone. This book looks at the complete picture of common STIs-- how they form, evolve, and transmit, as well as how they can be treated and managed with modern techniques, medicines, and tools.

Diagnostics to Pathogenomics of Sexually Transmitted Infections runs the spectrum of discussion ranging from introduction of causative pathogen, their pathogenesis to epidemiology, immunology, to anatomy and physiology of human genitalia and management strategies. The book offers in-depth chapter coverage on effect of probiotics on reproductive health; mucosal immunity in sexually transmitted infections; the role of circumcision in preventing STIs; Human Immunodeficiency Virus (HIV); genital herpes; molluscum contagiosum; genital warts; chlaymydia trachomatis; donovanosis; gonorrhoea; treponematoses; genital mycoplasms; bacterial vaginosis; vulvovaginal candidiasis; chlaymydia; scabies; chancroid, yeast infections; and more.

• Comprehensively compiles most of the major sexually transmitted infections

• Presents updated information on clinical aspects of sexually transmitted infections

• Examines the priorities in pathogenesis of human sexually transmitted infections and discusses new strategies of genomics and next-generation diagnostic tools used for detection of such pathogens

• Explores the future of rapid molecular diagnostic techniques and the challenges posed in the diagnosis of human STIs

• Includes bench to bedside content that will appeal to both basic and clinical researchers

By offering the latest knowledge about recent advances in sexually transmitted infections in an interdisciplinary fashion, Diagnostics to Pathogenomics of Sexually Transmitted Infections is the perfect book for virologists, microbiologists, infectious disease experts, vaccinologists, biomedical researchers, clinicians, pharmacologists, and public health specialists.
