General:
CBC, Sputum(culture), Radiography(chest), CT scan
Interstitial Lung Disease
Related to inflammation of alveoli
Patchy white, diffuse x-rays; associated with Mycoplasma induced pneumonia
Intra-alveolar space infection; most community acquired pneumonia & bacterial pneumonia
patchy white diffuse spots on lung x-ray
Opacities in the lungs; may depend on severity of disease; progression of pathology
General Signs and Symptoms:
Fever,Rigors, Cough, Runny nose, Dyspnea, Chest pain
Atypical in response to antibiotics; Generally stains poorly due to lack of peptidoglycan or irregular cellular wall or absence of one
Virulence Factors 11
Diagnosis 11
Immunofluorescent staining for the presence of the intercellular presence of C. pneumoniae
General Characteristics 11
Non-motile, grown within vesicles, no cell wall, obligate intracellular bacteria
Treatment 11
Azithromycin or Erythromycin for 14 days
Treatment 10
Tetracycline or Azithromycin of a week
General Characteristics 10
