Rationale:
Meningitis caused by concurrent infections with Cryptococcus neoformans, Streptococcus equi subsp. equi, and Mycobacterium tuberculosis is extremely rare.
Patient Concerns:
We present the case of a 63-year-old male patient who presented with headaches, dizziness, nausea, vomiting, and fever for the past 3 weeks.
Diagnoses:
The patient was diagnosed with concurrent cryptococcal, streptococcal, and tuberculous meningitis.
Interventions:
The patient received isoniazid, rifampicin, ethambutol, and levofloxacin for 1 month, in addition to liposomal amphotericin B with flucytosine for 2 weeks, followed by fluconazole with flucytosine for additional 2 weeks.
Outcomes:
The symptoms improved, and outpatient therapy was continued.
Lessons:
Infectious meningitis requires a combination of microscopy, culture, and rapid molecular diagnostics for early diagnosis and treatment.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis IV
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
