Mycobacterium Tuberculosis Molecular Infection Biology Pathogenesis Diagnostics And New Interventions

This book reviews recent advances in the molecular and infection biology, pathology, and molecular epidemiology of Mycobacterium tuberculosis, as well as the identification and validation of novel molecular drug targets for the treatment of this mycobacterial disease. Despite being completely curable, tuberculosis is still one of the leading global causes of death. M. tuberculosis, the causative organism – one of the smartest pathogens known – adopts highly intelligent strategies for survival and pathogenesis. Presenting a wealth of information on the molecular infection biology of M. tuberculosis, as well as nontuberculous mycobacteria (NTM), the book provides an overview of the functional role of the PE/PPE group of proteins, which is exclusive to the genus Mycobacteria, of host-pathogen interactions, and virulence. It also explores the pathogenesis of the infection, pathology, epidemiology, and diagnosis of NTM. Finally it discusses current and novel approaches in vaccine development against tuberculosis, including the role of nanotechnology. With state-of-the-art contributions from experts in the respective domains, this book is an informative resource for practitioners as well as medical postgraduate students and researchers.

Infectious diseases are the leading cause of death globally, particularly among children and young adults. The spread of new pathogens and the threat of antimicrobial resistance pose particular challenges in combating these diseases. Major Infectious Diseases identifies feasible, cost-effective packages of interventions and strategies across delivery platforms to prevent and treat HIV/AIDS, other sexually transmitted infections, tuberculosis, malaria, adult febrile illness, viral hepatitis, and neglected tropical diseases. The volume emphasizes the need to effectively address emerging antimicrobial resistance, strengthen health systems, and increase access to care. The attainable goals are to reduce incidence, develop innovative approaches, and optimize existing tools in resource-constrained settings.

The aim of this book is to provide detailed protocols for studying the molecular biology of the pathogen Mycobacterium tuberculosis, and its int- actions with host cells. As established mycobacterial laboratories move - wards exploiting the genome, and laboratories with expertise in other fields apply them to mycobacteria, both traditional and novel methodologies need to be reviewed. Thus the chapters in Mycobacterium tuberculosis Protocols range from perspectives on storage of strains and safety issues to the application of the latest functional genomics technologies. The last few years have been remarkable ones for research into M. tuber- losis. The most important landmark by far has been the completion of the genome sequence of the widely studied H37Rv strain (1). We can now predict every protein and RNA molecule made by the pathogen. This information is or will soon be enriched by the addition of genome sequences of other strains from the M. tuberculosis complex: a second strain of M. tuberculosis, My- bacterium bovis, and the vaccine strain, M. bovis BCG. Valuable comparative data will also be provided by the genome sequences of Mycobacterium leprae, Mycobacterium avium, and Streptomyces coelicolor. Another recent milestone for M. tuberculosis has been the development of efficient mutagenesis me- odologies, the lack of which has been a major handicap in functional studies.

Mycobacterium tuberculosis is the major cause of tuberculosis (TB) across the globe. Around one-fourth of the world’s population is infected with TB asymptomatically. Longer regimen of anti-TB drugs (longer treatment leading to poor adherence to treatment), interrupted anti-TB drugs treatment (long regimen with incomplete anti-TB treatment), and ineffectiveness of the anti-TB drugs due to the re-emergence of latent TB infections are just a few mechanisms that play a major hindrance to achieving the end of the global TB epidemic by 2035 as WHO plans. The emergence of drug-resistant in Mycobacterium tuberculosis and co-infections with HIV as well as SARS-CoV-2 poses a serious threat to global health agencies. It was reported that the TB cases in India and other endemic countries are two to three times higher than in the last few years. Different mechanisms were acquired by the bacteria to become multidrug-resistant such as an alternation in the target site, drug efflux by overexpression of efflux pumps, inactivation of drugs by enzymes and biofilms. Mechanisms adopted by bacteria and longer anti-tuberculosis treatment regimens are the greatest threat in TB control programs especially in malnourished, immune-compromised, M. tuberculosis co-infection with HIV and SARS-CoV-2 individuals in developing countries. There is a great need for shorter anti-TB regimens and novel drugs with a different mode of action to encounter the emergence of drug resistance in Mycobacterium tuberculosis. Combinatorial drug treatments by anti-TB drugs along with the repurposed drugs are also the novel choice against this deadly TB. The current issue will focus on different mechanisms adopted by mycobacterium to develop multidrug-resistant mycobacteria and the impact of SARS-CoV-2 pandemics in TB treatment and management. Furthermore, the modern techniques used for the early diagnosis and management of M. tuberculosis and its co-infection with HIV and SARS-CoV-2 are the point of innovative interest that shows the potential development in technologies and applications for the management of these co-infections.

The authors discuss fundamental questions about the biology, genetics, mechanisms of pathogenicity, mechanisms of resistance, and drug development strategies that are likely to provide important new knowledge about TB and new interventions to prevent and treat this disease.

Can today's innovative practices and molecular tools tame this ancient disease? One third of the world's population is infected with tuberculosis (TB), with about 10 million new cases annually. To combat TB and its agent, Mycobacterium tuberculosis, the World Health Organization launched The End TB Strategy, which aims to slash the suffering and cost of TB by 2035. This makes the second edition of Tuberculosis and the Tubercle Bacillus, edited by Jacobs, McShane, Mizrahi, and Orme, an extremely valuable resource for scientists and clinicians. The editors have gathered their colleagues from around the world to present the latest on the molecular biology of M. tuberculosis and related species, the host-pathogen interactions that enable invasion, and the host's immune response to M. tuberculosis infection. The basic, clinical, and translational research presented in this book supports the goals of WHO's End TB Strategy by driving toward the development of effective vaccines, rapid molecular diagnostics, and anti-TB drugs. Creating an effective tuberculosis vaccine. Understand the innate and adaptive immune response to M. tuberculosis infection, its study in established animal models, and how this information is being used to develop new vaccines against TB. Formulating new antituberculosis drugs. Learn the challenges and methods for evaluating new drugs in preclinical trials with a focus on drugs that work against "persisters" and those that act on the electron transport complex and ATP synthase of M. tuberculosis. Overcoming the challenges of diagnosing tuberculosis. Review new diagnostic tools that are simple, rapid, affordable, specific, sensitive, and safe, including molecular-based diagnostic methods such as GeneXpert MTB/RIF. Using molecular, genomic, and bioinformatics tools to understand the biology and evolution of Mycobacterium. Explore current research on the molecular mechanisms that M. tuberculosis uses to evade the immune system, enter a state of nonreplicating persistence, and become reactivated. The second edition of Tuberculosis and the Tubercle Bacillus presents the latest research on a microorganism that is exquisitely well adapted to its human host. This pathogen continues to confound scientists, clinicians, and public health specialists, who will all find much valuable information in this comprehensive set of reviews.

This book covers all the aspects related to the laboratory diagnosis of Mycobacterium. Laboratory diagnosis includes microscopic to advance molecular diagnosis. Moreover, it deals with the methods used to detect antimycobacterial susceptibility tests and drug resistance. Chapters cover most potential methods and techniques from traditional to advanced future diagnostics for identifying tuberculosis, NTM, and latent TB infections. Also discussed the challenges and opportunities in the diagnostic science of infectious disease. This book offers assistance to students, postgraduate medical students, researchers, medical practitioners, postdoctoral fellows, microbiologists, nurses, and public health officers working in tuberculosis control programs to understand various modalities for diagnosis and drug-resistance tuberculosis.

Tuberculosis emerged as an epidemic in the 1600s, began to decline as sanitation improved in the 19th century, and retreated further when effective therapy was developed in the 1950s. TB was virtually forgotten until a recent resurgence in the U.S. and around the worldâ€"ominously, in forms resistant to commonly used medicines. What must the nation do to eliminate TB? The distinguished committee from the Institute of Medicine offers recommendations in the key areas of epidemiology and prevention, diagnosis and treatment, funding and organization of public initiatives, and the U.S. role worldwide. The panel also focuses on how to mobilize policy makers and the public to effective action. The book provides important background on the pathology of tuberculosis, its history and status in the U.S., and the public and private response. The committee explains how the U.S. can act with both self-interest and humanitarianism in addressing the worldwide incidence of TB.
