Radiation Modification of Nanoparticles to Study Their Anti-biofilm Activity of Some Pathogenic Bacteria Along with Antimicrobial Agent.

Abstract

The presence of biofilms deteriorates safety issues in the water distribution network and the end consumers, especially when biofilms are located on inside pipe surfaces lead to microbial induced corrosion and harbor pathogenic bacteria such as Pseudomonas aeruginosa, Staphylococcus aureus and Proteus mirabilis. In the current study, from 48 different water samples, 108 bacterial isolates were obtained and were examined for biofilm formation via modified Congo Red Agar (mCRA) and tissue culture plate (TCP). In the current study, from 43 different water samples,108 bacterial isolates were obtained and were examined for biofilm formation via two different methods, modified Congo Red Agar (mCRA) and Tissue culture plate methods (TCP) revealed that, from 108 bacterial isolates represent modified Congo red agar results, the data showed 35 isolates (32.4%) were positive slime production and 73 (67.59%) were negative slime productions. Take in consideration that, the isolates were obtained from chlorinated water, the results of TCP showed that, out of 108 isolates, 37 isolates were high biofilm producers, 39 isolates moderate producers while 21 isolates were weak biofilm producers and 11 non-biofilm producers.
