Pseudomonas and Related Infections
Diseases Caused byPseudomonas
 is a common cause of infections in intensive care units. HIV-infected patients, particularly those in advanced stages, and patients with Cystic Fibrosis are at risk of community-acquired infections can develop in many anatomic sites, including skin, subcutaneous tissue, bone, ears, eyes, urinary tract, lungs, and heart valves. The site varies with the portal of entry and the patient’s vulnerability. In hospitalized patients, the first sign may be overwhelming gram-negative Sepsis and Septic Shock . Inburns,the region below the eschar can become heavily infiltrated with organisms, serving as a focus for subsequent bacteremia—an often lethal complication. . Draining sinuses, cellulitis, and Osteomyelitis may result. Drainage from puncture wounds often has a sweet, fruity smell. Folliculitis None External Otitis (Acute) None Ecthyma gangrenosumis a skin lesion that occurs in neutropenic patients and is usually caused byP. aeruginosa. It is characterized by erythematous, centrally ulcerated, purple-black areas about 1 cm in diameter occurring most often in moist areas such as the axillary, inguinal, or anogenital areas. Ecthyma gangrenosum typically occurs in patients withP. aeruginosabacteremia. is a frequent cause of Hospital-Acquired Pneumonia . In HIV-infected patients, bronchitis is common late in the course of Cystic Fibrosis . Isolates from patients with cystic fibrosis have a characteristic mucoid colonial morphology and result in a worse prognosis than nonmucoid is a common cause of nosocomial Introduction to Urinary Tract Infections (UTIs) , especially in patients who have had urologic manipulation or obstructive uropathy. Ocular involvement generally manifests as corneal ulceration, most often after trauma, but contamination of contact lenses or lens fluid has been implicated in some cases. causes Infective Endocarditis , usually on prosthetic valves in patients who have had open-heart surgery or on natural valves in IV drug abusers. infections can cause Bacteremia . In nonintubated patients without a detectable urinary focus, especially if infection is due to a species other than
