Tuberculosis (TB) remains to be one of the most challenging issues in healthcare. It continues to cause a high number of deaths, globally. According to the current WHO report, TB caused 784,000 deaths in 2015, and there were 10.4 million new TB cases reported in the same year. Based on this high mortality caused by TB, it is apparent that the disease has emerged among the top ten killers worldwide.
Therefore, this case study report provides a comprehensive discussion on the key epidemiological features of TB, including causative agent, prevalence, why TB is a serious threat, diagnostic, and issues associated with its diagnosis. Additionally, the study provides current treatment, drug resistance and future recommendations.

Excerpt from the Book
Issues Surrounding Diagnostic Methods
In retrospect, there is an increasing effort to develop diagnostic methods for detecting TB infection with high precision. In practice, the acid-fast bacilli are investigated under smear microscopy or cultured in laboratory media for further identification. In some cases, Mycobacterium tuberculosis bacilli are amplified for the detection of MTBC nucleic acids through the use of NAATs. However, culture is recommended as a confirmatory test.
A standard testing algorithm for active TB comprises of mycobacterial culture, chest radiography, phenotypic DST, NAATs, and sputum smear microscopy. Chest radiography has been found to exhibit up to 80% sensitivity in detecting active TB. Despite the fact that chest radiography is considered as an integral diagnostic algorithm, it does not provide confirmatory results; thus, there is need to incorporate microbiological tests.
The role of the mycobacteriology laboratory is to detect, isolate, identify and perform susceptibility tests on clinically significant mycobacteria from clinical specimens.
Chapter Summaries
Introduction: Outlines the global burden of tuberculosis as a leading cause of mortality and sets the scope for the case study report.
Tuberculosis and its Causative Agent: Explores the historical origin of the disease and classifies the various bacterial strains responsible for TB infections across species.
Current Prevalence and Severity of Tuberculosis Infections: Analyzes epidemiological data regarding TB incidence and mortality rates globally and specifically within the UK.
Why Tuberculosis is a Serious Problem: Discusses the challenges posed by variable vaccine efficacy and the exacerbating influence of HIV co-infection.
Issues Surrounding Diagnostic Methods: Reviews current testing algorithms, the gold standard of culture, and the necessity of incorporating molecular tests like NAATs.
Emergence of Antibiotic Resistance Strains: Examines current treatment regimens, the role of Directly Observed Therapy (DOT), and the growing threat of multi-drug resistant strains.
Recommendations for the Future: Proposes the development of shorter, more efficient drug regimens and improvements to the diagnostic infrastructure.
Conclusion: Summarizes the need for integrated global efforts, including poverty reduction and awareness campaigns, to achieve TB eradication.
