Micro- Things To Know Flashcards
S(T)aph, s(T)rep, and en(T)erococci are all what type of gram stain result?
Gram positive cocci
The most worrisome gram-negative diplococci is what organism
Neisseria meningitis
What are the ABC’s of Diplococci
Obviously, Nigeria meningitis, but also , Acinetobacter, Brucella and Moraxella Cararrhalis
Fifth disease is caused by what virus
Parvovirus B19
What disease gives you a slapped cheek rash
Fifth disease
What organism is a common cause of CAP or community acquired pneumonia
MRSA
Staph Aureus ( A-ROR-E-us) is most associated with what type of infection
Bone infections or osteomyelitis
Kle(BSI)ella University is known for what two infections
Blood and UTI infections
(P)seudomonas is known for what? What type of infection
(P)neumonia
CONS (need guns) coagulative staff is responsible for what type of related infection
Device associated
Is it alpha beta or gamma homolysis that creates a green appearance in the sheep’s blood auger
Alpha
Enterococci will create what type of homolysis in sheep, blood auger. This is due to the partial lysis of the sheep cells and gives a green appearance.
Alpha homolysis
Is it alpha, beta, or gamma homolysis that is a complete lysis or clearing of the sheep’s blood auger?
Beta homolysis
Is it alpha, beta, or gamma homolysis that creates a lack of lysis or no change to the sheep’s blood auger?
Gamma homolysis
Is it prophylactic, empiric, or therapeutic to give antibiotics prior to infection such as to prevent for overseas protection prior to a surgery or prior to dental work?
Prophylactic anabiotic use is to prevent remember the P for prophylactic and the P for prevent
Is it prophylactic, empiric, or therapeutic antibiotic use when antibiotics are given early prior to a known species being identified then tailored to the MIC
It is empiric antibiotic use remember that the M in empiric means to minimize
Is it prophylactic, empiric, or therapeutic to give antibiotics after the organism is known, and the antibiotic is tailored to the specific bug
This is therapeutic antics therapeutic is to control a known organism
Put the chain of infection in order mode of transmission, portal of entry, portal of exit, infectious agent, susceptible host
The chain of infection starts with the infectious agent, then to the portal of exit mode of transmission, portal of entry. Lastly, is the susceptible host. Remember, it starts with micros thriving it grows too much and they look for a way out they get in their car to go to another place through sneeze or cough, they find an entryway through a nose or mouth Into the new susceptible host 
What is the best type of testing that would act as a DNA blueprint for an organism if you need to determine if an outbreak is derived from the same source host?
Pulse field gel electrophoresis
What type of testing is considered the gold standard for CDF testing?
Toxigenic culture however it’s drawback is that it takes 2 to 3 days to perform
Which diagnostic test for CDF has the best sensitivity and specificity PCR, glutamate, dehydrogenase, toxigenic, culture, or EIA
Nucleic acid amplification test, including the PCR has both excellent specificity and sensitivity and yields rapid results, but is very expensive. The EIA is an expensive and rapid, but poor sensitivity and specificity culture has excellent sensitivity and specificity requires a secondary test for toxins. It requires 3 to 4 days to complete.
