Inkberry Holly Disease

Question

My Inkberry Holly bushes have developed dark spots on the leaves that ultimately turn completely dark brown or black. The branch supporting those leaves apparently dies. This has occured with bushes in close proximity with one being diseased and the other 6 feet away with no problem. My landscaping had 22 of these bushes. I have 14 remaining but some starting to show the disease. Could you please tell me what caused this problem and the cure?
