|
E. coli, Shigella, Edwardsiella, and Salmonella
|

|
|
Motility for Shigella
|
-
|
|
Which organisms are motility +?
|
E. coli, Edwardsiella, Salmonella, C. freundii
|
|
Which organisms are indole variable?
|
Y. enterocolitica, Shigella
|
|
which organisms are indole +?
|
E. coli, edwardsiella
|
|
which organisms are indole neg?
|
salmonella, c. freundii
|
|
Which organisms are Ornithine pos?
|
Y. enterocolitica, E. coli, Edwardsiella, Salmonella
|
|
Which organisms are Ornithine Variable?
|
Shigella, C. freundii
|
|
Which organisms are citrate pos?
|
Salmonella, C. freundii
|
|

|
Y.enterocolitica, E.coli, Edwardsiella, Shigella.
YEES |
|
WHich organisms are Lysine neg?
|
Y. enterocolitica, Shigella, C. freundii
|
|
Which organisms are lysine pos?
|
E. coli, Edwardsiella, Salmonella
|
|
What organism is lac neg?
|
Y. enterocolitica
|
|
Which organism is lac pos?
|
E. coli
|
|
Which of both patho and normal organisms are H2S producers?
|
SPEC
Salmonella Proteus mirabilis/vulgaris Edwardsiella Citrobacter freundii |
|
good way to know you've got edwardsiella:
|
Edwardsiella is
Indole pos and Citrate neg whereas Salmonella and Citrobacter f. are both Indole neg and Citrate pos |
|
If lysine is negative and citrate is negative, what should you be thinking?
|
y. enterocolitica or shigella, but not e.coli; they're all citrate neg, but e.coli is lysine pos
|
|
If H2S is produced the bug can only be:
|
Salmonella
Proteus Edwardsiella Citrobacter freundii |
|
If Motility is positive the bug is NOT:
|
Klebsiella
Shigella Yersinia enterocolitica at 37 |
|
If Indole is Neg and Citrate is Pos:
bug could be.. |
Citrobacter freundii
Enterobacter Salmonella Serratia |
|
If Lysine is deaminated, bug could be:
|
Proteus
Providencia Morganella |
|
Ornithine is NEVER positive for:
|
Klebsiella
Providencia |
|
Only bug that is BOTH
indole and citrate positive: |
Providencia
|
|
If Indole is Pos and
Citrate is Neg |
Morganella
Edwardsiella E. coli |
|
Of the pathogenics, only 2 are positive on urea:
|
Y. enterocolitica
C. freundii |
|
3-4+ urea:
|
Proteus, Morganella, Providencia
|
|
Only DNAse positive
|
Serratia
differentiates it from Enterobacter |
|
Genera with spores
|
bacillus
clostridium |
