It is truly amazing that this paper was ever published. First, there is a long history of attempting to correlate IC with infectious agents. Not only is this literature not acknowledged, but the final assessment that the findings represented false positives is not discussed. Amazingly, there are no controls collected from patients without IC but under the same conditions. Thus we do not know whether the alleged "nanobacteria," which may or may not even be living organisms, are even associated with IC, or whether random biopsies from all sorts of disorders might have yielded the same results.
