holly bush problem

I need help with my holly bushes. The leaves are turning yellow and are getting black spots. The holly bush next to it doesn't seem to be affected. Any help to save it will be appreciated.

 

These are two pics of the holly bush, the left one is infected?

 

Looks to me that you need to remove that infected one so that what ever it has doesn't spread to the unaffected one.

 

I would definitely remove the 'sick' one. See if you can find out what was eating on the 'sick' one and get spray for the healthy one...just in case.
