Diseases of actinobacter baumannii
Big in post-trauma infections, meningitis, bacteraemia, pneumonia
diseases by pseudomonas aeruginosa
Big in colonizing aseptic medical devices, bacteraemia, pneumonia ~ major cause of pneumonia in individuals with cystic fibrosis
physical attributes of acinetobacter baumannii
g-, strict aerobe! Commensal/environmental, motile (type IV pili),
physical attributes of pseudomonas
g-, facultative anaerobe, environmental bacterium, motile (flagella and type IV pili)

10% core genome
Plasmids
virulence factors acinetobacter
LPS, type IV secretion system, efflux pumps
virulence factors of pseudomonas
Can grow in microaerophilic or anaerobic conditions
Anaerobic growth with nitrate or nitrite as a terminal electron acceptor
Growth in a diversity of environments
○ Able to grow on a range of different carbon and nitrogen sources
○ Able to grow in diesel and jet fuels causing microbial corrosion
Able to grow in cleaning agents and disinfectants
resistance of Acinetobacter
Beta-lactams, aminoglycosides, quinolones using RND transporters
Pseudomonas resistance
Carbapenems!!
Some are resistant to polymyxins, most other common antibiotics using RND transporters
