- Produces endotoxin, Exotoxin A, and Exoenzyme S
- Important cause of immunocompromised infections
Clinical Diseases
- Septic arthritis
- Pneumonia
- CNS infection
- Chronic mastoiditis
- Osteomyelitis
- UTI
- GIT infection
- Ecthyma gangrenosum (wound with blue-green pus and grape-like odor)
Diagnosis and Treatment
- Culture: blood, CSF, urine, lung aspirate
- Treatment: Carbenicillin, Ticarcillin, Gentamycin, Tobramycin, Amikacin, Ceftazidime
