  1. Pseudomonas aeruginosa By:LisaZemola

  2. Classification Genus: Pseudomonas Species: Pseudomonas aeruginosa Kingdom: Bacteria Phylum: Proteobacteria Class: Gamma Probacteria Order: Pseudomonadales Family: Pseudomonadaceae

  3. Characteristics • Shape:Rod-shaped with unipolar motility. • Opportunistic human and plant pathogen. • secretes a variety of pigments, including: • pyocyanin (blue-green) • pyoverdine (yellow-green and flourescent • Pyorubin (red brown)

  4. Characteristics Continued • Pseudomonas aeruginosa is a moderately-sized gram-negative bacillus. • Possess a monotrichous arrangement of flagella. • Does not ferment sugars. • P. aeruginosa is classified as an aerobic organism, but also as a facultative organism.

  5. Pathogenesis • An opportunistic, nosocomial pathogen of immunocompromised individuals. • typically infects: the pulmonary tract, urinary tract burns wounds and also causes other blood infections.

  6. Habitat and Source Found In: • soil • water • vegetation • decaying organic matter • throughout the hospital environment • and frequently carried in the respiratory and intestinal tracts of hospitalized patients and immunocompromized hosts. • Adaptation to microaerobic or anaerobic environments is essential for certain lifestyles of P. aeruginosa Ex. Lung infection in cystic fibrosis

  7. Health Related Issues • Can lead to fatal pnemonia • Produce tissue-damaging toxins • individuals with compromised immune systems such as those infected with HIV, organ transplant recipients and burns patients are particularly prone to pseudomonad infections • It is the most common cause of infections of burn injuries and of the external ear (otitis externa), and is the most frequent colonizer of medical devices

  8. Treatment • Usually treated with a combined use of aminoglycosides and beta-lactam antibiotics • Antibiotics that have activity against P. aeruginosa include: • aminoglycosides • Cephalosporins • antipseudomonalpenicillins: • ureidopenicillins and carboxypenicillins (piperacillin, ticarcillin: P. aeruginosa is intrinsically resistant to all other penicillins) • Carbapenems • monobactams (aztreonam)
