I love your whole series of videos, markmicrobiology (& friends!). They are so informative, yet so "brief", that they really help study, and bear repeated watching very well. Thank you. Question on this particular video: When do "you guys" use the Campy plates? Every incoming stool specimen?
E. coli 0157H7 is indeed a member of the enterobacteriaceae, it is pathogenic and ferments lactose. However it does not ferment sorbitol well like the other E. coli, and can therefore be differentiated on Sorbitol-MacConkey agar (lactose is replaced by sorbitol).
0157H7 is colorless on Sorbitol-MacConkey agar. It produces shiga-like toxin via a bacteriophage. Shigella produces shiga-toxin from a defective bacteriophage that is chromosomal.
Yes, Dan, the lab tests for Campylobacter in each stool specimen. They also test for Salmonella, Shigella, E. coli 0157 and Shiga toxin.
The Zofran mouse pad is a nice touch, while talking about all these organisms that can make you sick to the stomach :-)
That yellow color is indicated as normal flora on xld . A simple note to know

This helps a lot! Thank you for posting!
Thank you. That wa svery useful
This has really helped me with my lab report
Lol...I can hear the walkaway in the background. That sound never gets old haha
useful information, thanks
do we use all these media in the same time for every stool specimen!
or is it specific?
how do you enrich stool culture sir
thank u so much
is E.coli o157h7 , lactose non fermenter and it is pathogeic? is E.coli o157h7 one of the member enterobacteriaceae?

is E.coli 0157H7 does not ferment sorbital and it is coloress colony?
is e.coli 0157H7 prdoucing shiga toxin by serotype method?
0157H7 is colorless on Sorbitol-MacConkey agar. It produces shiga-like toxin via a bacteriophage. Shigella produces shiga-toxin from a defective bacteriophage that is chromosomal.
well done
you did not have to open it & expose the culture.
My sir
I love stool!!
