5. Chinese restaurant ?.....i think it is most likely B Cereus...the guy probable ate fried rice.

I think the answer is: 2- E.Coli, the non invasive form,

For Salmonella, it is invasive bact. so it leads to the presence of blood in stool,
for shigella it is also invasive,
For Staph Aureus, it is limited diarrhea and recover rapidly,

For Vibrio Cholera it is watery rice diarrhea,
For B.Cereus, it only effect of Toxin, no bacteria, so I think it is limited,
but I am still confused about Vibrio Cholera and B.Cereus,


BUT, I can tell that E.Coli is the cause for the traveler's diarrhea,


Please let us know the answer,

TO chimonze
LOOK AT eating non vegetarian food

THE ANSWER IS 4

BUT

NB/
I THINK THE QUESTION IS NOT CORRECT 100% WHY?
SOMETIMES SALMONELLA FOOD PISSONING CAUSES OCCASIONAL BLOOD PER STOOL
LOOK AT KAPLAN 2007 MICROBIOLOGY PAGE 69

wait here,

It could be B.Cereus, because the guy ate non vegetarian food, and the means he ate meat,
B. Cereus can survive the first cooking,

so it is B. Cereus,


Please let us know the answer,
