Mycobacterial Infections and Other Intracellular Pathogens

Tuberculosis treatment involves long-term therapy (6-9 months) due to growing drug resistance.
The most common treatment for active TB is isoniazid (INH) in combination with three other drugs—rifampin, pyrazinamide, and ethambutol.
Bacille Calmette-Guérin (BCG) vaccination and pasteurization of milk are preventive measures for tuberculosis.
Mycobacterium bovis causes scrofuloderma, a childhood disease characterized by enlarged, caseous cervical lymph nodes.
Mycobacterium leprae mainly affects the skin and nerves, causing slow, progressive chronic disease.
Lepromatous leprosy is characterized by a depressed cell-mediated immune response and affects mainly the mucosa.
Tuberculoid leprosy involves an intense cell-mediated immune response and results in nerve damage and extremity loss.
Mycobacteria other than tuberculosis (MOTT) include M. avium, M. intracellulare, M. kansasii, and M. fortuitum, causing pulmonary infections in compromised patients.
Legionella pneumophila, found in soil and water, causes Pontiac Fever and "Legionnaires" disease, with older men who smoke and drink excessively being at higher risk.
Chlamydiae, Rickettsiae, and Mycoplasmas are a miscellaneous group of organisms with properties common to both bacteria and viruses, causing divergent human diseases.
Chlamydia trachomatis causes ocular, genital, and neonatal infections, being the most common sexually transmitted disease in the UK.
Rickettsiae, including Rickettsia and Coxiella, cause diseases like typhus, spotted fevers, and Q fever, which proliferates in the respiratory tract and then disseminates to other organs.
