ONPG test detects only presence of beta galactosidase enzyme whereas lactose fermentation requires the presence of permease as well as beta galactosidase enzyme.

Can shigella sonnei be a lactose non fermenter My tests are as followed TSI KA Methyl red VP - citrate - urea - NO3 degraded to NO2 H2S - motility -. all points to shigella but it's nonferm?

S.sonnei is not a true lactose fermenting bacteria (see.. http://www.pubmedcentral.nih.gov/picrender.fcgi?artid=271578&blobtype=pdf)But is a delayed lactose fermenter as it does not have the enzyme permease to transport lactose through its cell wall.However an ONPG lactose fermenting test does not require permease to allow the bacterium to ferment lactose so in an ONPG test the shigella sonnei will appear as lactose fermenting positive.Hope this helps!!2nd year BMS student

What are the target cells affected by aldosterone?

The target cells of aldosteron are in the distal convulated tubules. Aldosteron there spreads into the cells, makes complexes with the receptors of the nucleus and codes for genes that are responsible for the proteins (e.g. sodium permease) and ferments (citratsintase, carboanhidrase) that are important for the transfer of sodium ions.
