NON FERMENTIVE GRAM-NEGATIVE BACILLI Flashcards
most commonly isolated nonfermentative bacilli
metabolism: respiratory
straight and slender
pseudomonas
CA of blue pus
pyocyanin producer
p. aeruginosa
most commonly encountered gram neg bacterium which is not an enterobacteriaceae
seen in distilled water, chlorinated water, hot tubs, contact lens, whirlpools
p. aeruginosa
fruity ‘grape like’ odor or corn ‘tortilla/taco’ odor- BAP
p. aeruginosa
leading cause of respiratory tract infections
3rd most common cause of gram neg bacillary bacteremia
3rd most common cause of hospital acquired infection
p. aeruginosa
CA of ecthyma gagrenosum, swimmer’s ear, hot tub/jacuzzi syndrome (necrotizing skin rash), infection of nail beds
p. aeruginosa
isolated from contaminated blood products, cosmetics
associated transfusion-associated septicemia
p. fluorescens, p. putida
differential and selective medium (pyoverdin and pyocyanin- P. aeruginosa)
cetrimide agar
can be distinguished from p. putida by its inability to oxidize xylose
p. monteilii
identification of bacteria by testing their vulnerability to bacterial viruses
phage typing
member of family moraxellaceae
2nd most frequently isolated nonfermenters
acinetobacter
plump, gram neg bacilli, appear in pairs
MacConkey: purplish colonies
BAP: gummy colonies
acinetobacter
specie of acinetobacter
glucose-oxidizing, non-hemolytic strain
a. baumanii
specie of acinetobacter
glucose-non oxidizing, non hemolytic strain
a. iwoffi
specie of acinetobacter
glucose non oxidizing, hemolytic strain
a. hemolyticus
3rd most commonly isolated nonfermentative gram neg bacilli
can contaminate blood drawing equipment and disinfectants
stenotrophomonas maltophilla
associated with pseudoinfections, maltose loving
s. maltophillia
involves contact with heavily contaminated medical devices
burkholderia
pneumonia in patients with cystic fibrosis
b. capacia
CA of glander’s/farcy disease- severe infx in horses and donkeys
potential bioterrorism agenr
b. maliei
CA of meloidosis- glanders like disease
b. pseudomaliei
isolated in muddy soils, rice paddies
can survive within phagocytes- VIETNAMESE TIME BOMB
EARTHY odor
b. pseudomaliei
feather-edged non pigmented colonies
FRUITY ODOR resembling APPLES OR STRAWBERRIES
alcaligenes fecalis
morax-axemfeld bacillus
PIT THE AGAR
moraxella lacunata
CA of blephanoconjunctivitis/ angular conjunctivitis
moraxella lacunata
opportunistic pathogen affecting the immunocompromised patient with neutrophil defects
VIOLET pigmented
chromobacterium violaceum
