Abstract
A total of 161 different Streptomyces isolates were recovered from 5 soil samples representing the driest habitats of Jordan. These were then characterized and assessed for their antagonistic activity against four clinical multi-drug resistant Pseudomonas aeruginosa test pathogens. Results indicated that only 3 strains out of 139 and 6 out of 22 isolated at 27°C and 45°C, respectively, were active against at least three strains of pathogenic Pseudomonas. However, three Streptomyces strains (J2b, J4, and J12) that were isolated at 45°C inhibited all of the tested pathogens with an inhibition zone ranging between 5 and 16 mm in diameter. Data obtained from comparing the inhibition activity of these unique Streptomyces strains toward multi-resistant Pseudomonas pathogens with standard used antibiotics revealed that these isolates produce possible different inhibitory bioactive compounds other than the standard antibiotics.
