Studying of antagonistic activity of some probiotics against bacteria P.mirabilis isolated from kidney stones

Abstract

This study Included (68) grit kidneys samples collected from patients undergoing surgeryl in hospitals in Tikrit city from period between April 2012 to May 2013. The results showed that (64.71%) of males and (35.29 %) of females were infected, the propotion of males to females (1.83: 1).Results of biochemical tests and API-20system showed that E.coli and Ps.aeruginosa were the most frequent bacterial isolates among other isolated bacterial species with percentage (30.76%) and (21.22%), respectively, while P. mirabilis was (15.38%) followed by bacteria and Kl.pneumoniae Citrobacter. freundii with isolation percentage (9.6%) and (5.67%) respectively. other species such as (Staph. aureus,, Acinetobacter. freundii, E.faecalis Serratia. marscenes) accounted (1.92%). Antigonstic activity of six types of probiotics against P. mirabilis were studied. Results showed that all probiotics types showed inhibition activity against P.mirabilis isolates and diameter of inhibition zone was highest (21.6 ml), when probiotic L. delbruckii used, while L. acidophilus showed less inhibitory activity against P. mirabilis isolate, the diameter of inhibition zone was 15.1.
