Molecular Characterization of Mycobacterium tuberculosis Drug Resistance Mutations Among Newly Diagnosed Tuberculosis Patients in Nigeria
Background
Tuberculosis remains a major public health challenge in Nigeria, particularly with the emergence of drug-resistant strains. Resistance to first-line anti-tuberculosis drugs threatens treatment effectiveness and disease control efforts. Molecular characterization of resistance-associated mutations enables rapid diagnosis and informs treatment decisions. Understanding the distribution of resistance mutations among newly diagnosed patients is essential for strengthening tuberculosis surveillance and management. This study seeks to investigate genetic mutations associated with drug resistance among Mycobacterium tuberculosis isolates.
Research Objectives
- Determine the prevalence of drug-resistant tuberculosis among newly diagnosed patients.
- Identify mutations associated with resistance to first-line drugs.
- Assess patterns of multidrug-resistant tuberculosis.
- Examine demographic factors associated with resistance.
- Evaluate implications for tuberculosis control programs.
Research Questions
- What is the prevalence of drug-resistant tuberculosis among newly diagnosed patients?
- Which genetic mutations are associated with resistance?
- How common is multidrug-resistant tuberculosis?
- Which demographic factors are associated with resistant disease?
- What implications do resistance patterns have for treatment?
Suggested Methodology
A molecular epidemiological study will be conducted using sputum samples from newly diagnosed tuberculosis patients. Gene-based molecular assays will be used to detect resistance mutations. Statistical analyses will evaluate mutation frequencies and associated patient characteristics.
