Stool Cultures to identify pathogens

[@markmicrobiology]

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

[@jessicapalang3858]

This helps a lot! Thank you for posting!

[@danharty7517]

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?

[@mzdbnell]

This has really helped me with my lab report

[@godtube286]

Lol...I can hear the walkaway in the background. That sound never gets old haha

[@abdelrahmanomara4984]

do we use all these media in the same time for every stool specimen! or is it specific?

[@CrescensiaMabhudhu]

Thank you. That wa svery useful

[@faticonaful]

useful information, thanks

[@muralibond1373]

how do you enrich stool culture sir

[@microbio82]

thank u so much

[@باسمالشمراني-ص9ر]

is E.coli o157h7 , lactose non fermenter and it is pathogeic? is E.coli o157h7 one of the member enterobacteriaceae?

[@markmicrobiology]

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).

[@باسمالشمراني-ص9ر]

is E.coli 0157H7 does not ferment sorbital and it is coloress colony? is e.coli 0157H7 prdoucing shiga toxin by serotype method?

[@markmicrobiology]

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.

[@باسمالشمراني-ص9ر]

well done

[@WabuhWabuh]

you did not have to open it & expose the culture.
