That is another article by Wormser. He studied cases of people who had repeated EM (bullseye rashes). The methodology is actually clever, looking at the OpsC protein. But of course he knows this is going to be cited out of context to imply that people with chronic Lyme are really just being re-infected. As you noticed, the bullseye rash usually occurs immediately after infection. Most people with chronic Lyme don't get repeated rashes, and this study is irrelevant to them.
