Chlamydophila pneumoniae patrí k najrozšírenejším ľudským patogénnom na celom svete. Je nielen významnou príčinou pneumónií, ale mnohé štúdie naznačujú možný vzťah medzi infekciou C. pneumoniae a kardiovaskulárnymi chorobami (KVCH). Celkove sme vyšetrili 228 pacientov s vybranými KVCH (hypertenzia, ischemická choroba srdca a rekonštrukčný chirurgický zákrok na cievach) na prítomnosť IgG a IgA protilátok proti C. pneumoniae metódou ELISA. Zo 150 pozitívne reagujúcich vzoriek sér sme 80, ktoré mali podobné hladiny IgG a IgA protilátok, ďalej vyšetrili metódou imunoblotu. IgG protilátky boli namierené predovšetkým voči 35kDa a 39kDa proteínom, ako aj voči 50-54 a 56-60 kDa proteínom C. pneumoniae. Pokiaľ ide o IgA protilátky, tieto reagovali najčastejšie s 50-54 a 56-60 kDa proteínmi.

Chlamydophila pneumoniae, one of the most prevalent human pathogens worldwide, is not only a significant cause of pneumonia, but may also be associated with cardiovascular diseases (CVD) as suggested by multiple studies. A total of 228 sera from CVD patients with hypertension, ischemic heart disease or previous reconstructive vascular surgery were screened for the presence of anti-C. pneumoniae IgG and IgA antibodies by ELISA. Out of 150 positive serum samples, 80 with similar IgG and IgA levels were investigated by immunoblot (IB). IgG antibodies were directed predominantly against the 35 kDa and 39 kDa proteins as well as 50-54 and 56-60 kDa proteins of C. pneumoniae. IgA antibodies reacted most frequently with the 50-54 and 56-60 kDa proteins.
