Study Notes
Acute Otitis Media
- Pathogens: Haemophilus influenzae, Streptococcus pneumoniae, Moraxella catarrhalis
- Neonates: Group B streptococci, gram-negative enterics, S. aureus
- Children: S. aureus (including MSSA and MRSA), Group A streptococci, Klebsiella kingae (under 3 years old)
- Adults: S. aureus, gram-negative enterics
Osteomyelitis of Hematogenous Source
- Pathogens: S. aureus (including MSSA and MRSA), Group A streptococci
- Children: S. aureus (including MSSA and MRSA), with Group A streptococci, Klebsiella kingae(less than 3 years).
- Adults: S. aureus, gram-negative enterics
Osteomyelitis Due to Spread from Contiguous Sites
- Pathogens: S. aureus, gram-negative pathogens, mixed infection
- Spread: Head or neck, soft tissue infections, streptococci, genitourinary tract infections
- Additional pathogens: P. aeruginosa, S. aureus.
