Sketchy Micro: Salmonella Flashcards
Salmonella is a ______________ bacteria.
Gram-negative, motile, rod-shaped
Think of the moving tail of the salmon on the table.
What lab test indicates Salmonella?
Black growth on Hektoen agar (just like the black plate that the salmon is on in the Sketchy video)
The glass case symbolizes that Salmonella is _____________.
encapsulated
In terms of routes of infection, how do Salmonella and Shigella differ?
They both are ingested gastrointestinally, but Salmonella is acid-labile (like the lemon slice) so it requires a much higher dose than Shigella (which is not acid-labile).
Salmonella typhii typically colonizes patients’ _____________.
gallbladders (just like the seagull with the Typhoid Mary apron)
Which strain of Salmonella is found in chicken?
Salmonella enteriditis
Salmonella typhii can cause a __________ rash on the abdomen.
erythematous macular (like the spotted apron)
Salmonella typhii is the most common cause of ___________ in patients with sickle cell disease.
osteomyelitis (represented by the seagull holding the sickle above the bones of the salmon)
Salmonella typhii often causes constipation, but it can cause diarrhea that looks like _____________.
pea soup (so Sketchy drew some green droppings that look like pea soup behind the seagull)
The best antibiotic for Salmonella typhii is ____________.
fluoroquinolones
What is a type 3 secretion system (T3SS)?
It is a needle-like system that some bacteria use to inject themselves into eukaryotes.
Salmonella __________ has a vaccine.
typhii
Salmonella enteriditis has a ___________ to help infect eukaryotes.
T3SS
Like Listeria monocytogenes, both strains of Salmonella are _______________.
facultative intracellular, meaning they can live outside or inside host cells (think of the open cages that the birds can walk in and out of)
Salmonella lives within _____________ in human hosts.
macrophages (like the macrophage cage behind each bird)
