At any rate, a couple decades ago, he fluoroimaged borreliae in a few abortive fetuses - possibly also in some other situations of transplacental passage, I forget. I think(?) he just means that spriochetal cyst images have not successfully competed for space in new texts or editions. This would accord with the more general eclipse of the idea of bacterial pleomorphism. At least some " pleomorphic variants " isolated (and preserved) by old workers have turned out (according to stronger genomic age technology) to actually be separate strains or species - rather than being merely different phenotypes of the same genotype. I vaguely understand that this has been a major factor in tarnishing pleomorphism theory generally. As competition for lab spots has increased over the decades, it would make sense that the possibility of " recovering " your standing in the competition for your own lab, after having once been associated with a " tainted " topic, has decreased. Therefore it can sometimes be hard for a tainted idea to make a comeback even if there are some arguments in its favor. As for the question of whether the spirochetal cyst could be illegitimate or artifactual, I have no doubt whatsoever that it is genuine. Cell-wall-deficient bacteria are one sort of pleomorphism that is fully accepted as real, but I think the occurance or at least the pathogenicity of CWD in vivo are generally held in doubt by the larger community.
