The Mess That Is Micro II - Grab Bag Flashcards
Obligate anaerobes
Actors back in the closet can’t breathe.
Actinomyces, bacteroides, clostridium.
These bacteria lack catalase and / or superoxide dismutase and are sensitive to oxidative damage.
Generally foul-smelling and are difficult to culture.
Produce gas in tissue (co2 and h2)
Aminoglycosides are ineffective against anaerobes because the antibiotics require o2 to enter into bacterial cell
Obligate aerobes
Nagging pests must breathe
Nocardia, pseudomonas, mycobacterium TB.
Reactivation of mycobacterium TB after immune compromise or TNF-alpha inhibitor use has a prediliction for the apices of the lung which has the highest po2.
Which antibiotics require oxygen to enter into the bacterial cell?
Aminoglycosides
Obligate intracellular bateria
My cells are RiCh in bacteria
Rickettsia, chlamydia
Facultative intracellular
Nice salmon bring my french legion your list
Neisseria, salmonella, brucella, mycobacterium, francisella, legionella, yersinia pestis, listeria
Encapsulated bacteria
Clumsy Sam collapsed on his SHIN B-Side the capsule
Klebsiella Salmonella E coli Shin - Strep pneumo, H flu B, Neisseria meningitidis Group B strep
Encapsulated bacteria are opsonized, then cleared by the spleen. Asplenics have decreased opsonizing ability and are at risk for severe infections. Give s pneumo, h flu, and n meningitidis vaccines.
Catalase positive organisms?
The cat aspirated pseudofed and listerine but survived to eat candy and other stuff
Aspergillus Pseudomonas Listeria Serratia E coli Candida S aureus
Catalase degrades H2O2 before it can be converted to microbicidal products by the enzyme myeloperoxidase. People with chronic granulomatous disease (NADPH oxidase deficiency) have recurrent infections with catalase positive organisms.
Encapsulated bacterial vaccines
SHIN -
PCV - prevnar - pneumococcal conjugate vaccine
PPSV - no conjugate protein
H flu B - conjugate vaccine
Meningococcal vaccine - conjugate vaccine
Urease positive bugs
The prostitute noticed cryptic piles of skin, urine, sap at the club
Proteus Nocedia Cryptococcus H pylori Ureaplasma S saprophyticus S epi Klebsiella
Pigment that actinomyces israelii produces
Israel has yellow sand - yellow
S aureus
Yellow
Pseudomonas aeruginosa
Blue-green pigment
What are the oxidase positive organisms?
Legions at Camp Pile More Coal (on the fire to make) Nice Ox Soup.
Legionella Campylobacter H pylori Moraxella Cholera Neisseria Oxidase positive Pseudomonas
