Přesný výklad by případně zájmu jistě podal na dotaz sám autor. Pod originálním textem

Také má smysl si znovu přečíst originál v angličtině, který doznal postupem času drobných změn, které v dostupném českém překladu nejsou:

"... In treating the disease, it makes sense to use a schedule of antimicrobial agents which is effective against other potential pathogens of the CNS including Borrelia garini and B burgdorferi. These spirochaetes have been known to cause a serologically negative MS-like illness. Chronic infections with these organisms are generally difficult to detect serologically; the EIA test is particularly prone to giving false negative results. Chronic borreliosis may be much more prevalent than is now believed; B. burgdorferi has been identified in avian ticks infesting songbirds [Morshed MG, Scott JD, et al., Migratory songbirds disperse ticks across Canada, and first isolation of the Lyme disease spirochete, Borrelia burgdorferi, from the avian tick, Ixodes auritulus. J Parasitol. 2005 Aug;91(4):780-90.] and has been posited as a reservoir of borrelial infection in Europe [Comstedt P, Bergstrom S, Olsen B, et al., Migratory passerine birds as reservoirs of Lyme borreliosis in Europe. Emerg Infect Dis. 2006 Jul;12(7):1087-95.] Given the likelihood of chronic C pneumoniae infection causing a decreased efficiency of host systems, one might speculate that chronic C pneumoniae infection may prevent resolution of borreliosis. It would also make sense to cover for Rickettsiae and Mycoplasma sp. and cell-wall deficient forms. MS and other initially relapsing-remitting but ultimately progressive diseases may have a polymicrobial phase: the punctured vasculitis caused by Chl pneumoniae would provide an easy portal of tissue-entry for blood-borne organisms. Microbiologists are beginning to recognise that, in many chronic infections, an altered host physiology provides a niche for a host of secondary organisms: an obvious example is chronic HIV disease, where the pathogen which initiates the disease is rarely the pathogen which causes the final event which results in death..."

Zjednodušeně, kde je chlamydie, tam se daří dalším potvorám, čili předpokladem ke zdárnému zbavení se souběžných či následných nákaz je zbavení  se chlamydií.
