Hi every one , Eid Mubarak
Today we will do the non motile, non H2S producer groups of ENTEROBACTERIACEAE 1/shigella 2/proteus

Thank you.Eid Mubarak
Okay.

I think it should be yersinia.proteus H2s producible and highly motile.

rukhz , you are very correct, am sorry for this mistake

And also invade M cell(imp), polymerizes actin jet trails to go laterally without going to ECF unlike salmonella so rarely invade blood vessels and cause bacteremia unlike salmonella.
Plus very few organism required to cause infection(1-10). Thank you
