My chest x ray came back with bronchitis.
Like I said above, likely mycoplasma.
AI clip:
Mycoplasma bronchitis is a respiratory infection caused by the bacterium Mycoplasma pneumoniae. It's often characterized by a persistent, dry, hacking
cough that can last for weeks or even months, longer than typical viral bronchitis.
Here's a breakdown of its key features:
Causative Agent:
Mycoplasma pneumoniae, a unique bacterium that lacks a cell wall, making it resistant to many common antibiotics that target cell walls (e.g.,
penicillin).
Transmission: Primarily spread through respiratory droplets from coughing or sneezing, making it common in close living quarters like
schools, dorms, and military barracks.
Symptoms:
Persistent dry cough: This is the hallmark symptom, often worse at night.
Sore throat
Headache
Fever
(often low-grade)
Fatigue/malaise
Chest discomfort
Earache (less common)
Diagnosis: Can be challenging as symptoms overlap with other respiratory
infections. Diagnosis often involves a combination of:
Clinical evaluation: Doctor's assessment of symptoms.
Chest X-ray: May show mild infiltrates,
though often normal.
Laboratory tests: Blood tests (antibodies), PCR tests (detecting bacterial DNA/RNA) are more definitive but not always routinely
performed.
Treatment: Antibiotics effective against Mycoplasma are used, typically macrolides (e.g., azithromycin, erythromycin) or tetracyclines
(e.g., doxycycline) or fluoroquinolones. Penicillins and cephalosporins are ineffective.
Complications: While usually mild and self-limiting,
complications can occur, including pneumonia ("walking pneumonia"), asthma exacerbation, reactive airways disease, and, rarely, neurological or
cardiac issues.
Course: The infection can have a gradual onset and a prolonged course, with the cough lingering long after other symptoms improve.
In
essence, Mycoplasma bronchitis is a prolonged, irritating, and often non-severe respiratory infection that requires specific antibiotic treatment due
to the unique nature of the causative bacterium. It's notorious for its persistent cough and can be difficult to differentiate from other forms of
bronchitis without specific testing.
