Study Notes
Bacterial Infections of Lower Respiratory System
- Diphtheria is caused by Corynebacterium diphtheriae, with an approximately 10% mortality rate even with treatment
- Immunization with toxoid, included in childhood DTaP vaccination, is highly effective in preventing diphtheria
- Pneumococcal pneumonia, caused by Streptococcus pneumoniae, accounts for about 1/3 of adult community-acquired pneumonia cases in the US
- Pneumococcal pneumonia is characterized by symptoms such as cough, chest pain, and rust-colored sputum, and is usually treated with antimicrobials
- Klebsiella pneumonia, caused by Klebsiella pneumoniae, is a common cause of healthcare-associated infections and is distinguished by bloody jelly-like sputum
- Klebsiella pneumoniae is a Gram-negative rod with a large capsule and is often transmitted through contact or medical equipment
- Mycoplasma pneumonia is the leading cause of pneumonia in children and young adults, often referred to as "walking pneumonia"
- Mycoplasma pneumoniae lacks a cell wall and can attach to respiratory epithelium, causing interference with ciliary action
- Mycoplasma pneumonia is spread by aerosolized droplets and tends to be more common in summer and early fall
- Antibiotic treatment is used for Klebsiella pneumonia, but more strains are becoming antibiotic-resistant
- There is a conjugate vaccine available for pneumococcal pneumonia, and no vaccine for Klebsiella or Mycoplasma pneumonia
- Infection control measures and wise use of antimicrobials are crucial for preventing the spread of these bacterial respiratory infections
