Objectives:
Bacterial DNA isolated from the intestinal tract of 11 American and 30 Slovak HIV/AIDS patients were analyzed by colony and dot blot hybridization assay for HIV-1 specific sequences. Secondly, PCR using primers specific for the HIV-1 gag, pol and env genes for detection of HIV-1 sequences in these DNA were performed.
Results:
Intestinal bacteria DNA of HIV/AIDS patients hybridized in colony and dot blot hybridization assay for HIV-1 specific sequences. PCR products synthesized on specific primers of HIV-1 gag (115 bp), env (142 bp), pol-env (1484) genes were found to be for more than 90% homologous to the corresponding sequence in HIV-1.
Conclusions:
Intestinal bacteria of HIV/AIDS patients are bearing sequences for more than 90% identical with those of HIV-1.
