Clostridioides difficile
gram pos | anaerobic
27
Bacteroides fragilis
gram neg | anaerobic
28
What color does gram positive bacteria stain?
purple, because they have a thicker cell membrane and will absorb and retain more of the blue dye
29
What color does gram negative bacteria stain?
pink, because they have a thinner cell wall that does not stain very well. After the purple stain, the red counter stain is applied, so it looks pink
30
What type of bacteria has a thick peptidoglycan layer?
gram positive
31
What type of bacteria has an outer membrane with LPS and thin peptidoglycan layer?
gram negative
32
If the bacteria has a morphology as part of its name, what type is it?
gram positive
33
What are the gram neg bacteria that are beta-lactamase producers? Hint: HnPEcK
``` Haemophilus influenzae Neisseria Proteus E. coli Klebsiella ```
34
What bacteria are Extended-spectrum beta-lactamases (ESBLs)? They can inhibit all penicillins and cephalosporins.
Klebsiella | E. coli
35
What bacteria are Carbapenem-resistant Enterobacteriaceae (CRE)? They are multi-drug resistant, produce beta-lactases, and carbapenemases.
Klebsiella | E. coli
