Biological Balance Role of Oxidative Status for Some Bacterial Species

Abstract


It has been chosen three types of bacterial species consisting gram positive and gram negative types, in order to evaluate the oxidative status of culture broth. E. coli is normal flora with pathogenic bacteria species such as Staphylococcus aurous and Klebsiella pneumonia. The results shows that E. coli has different criteria than others, of them reduced glutathione appear to be higher in the Klebsiella pneumonia in association with increased amount in Glutathione-S-transfrease activity to about 3.3 µU/L which gives indication about its defense system against free radicals peroxynitrate to reduced it to the a mount of 50 pM, however the indication of lipid peroxidation malondialdhyde (MDA) calculated to be 0.138 M. This new biological balance role of such status has been proved.

Keywords: Bacteria, Oxidative chess, lipid peroxidation, Glutathione-S-transfrease(GST), Peroxynitrate
