The Streptomyces flora of Badia region of Jordan and its potential as a source of antibiotics active against antibiotic-resistant bacteria

摘要

A total of 60 different Streptomyces isolates were recovered from 12 soil samples collected from the Badia region north-eastern of Jordan. These were then characterized by conventional methods and assessed for their antagonistic activity against three pathogenic and antibiotic-resistant bacteria. Results indicated that grey and white colour series were the most abundant with 30% of all isolates active against, at least, one of the test organisms; Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae. Overall screening results revealed the characterization of four Streptomyces isolates (I_7, AC_(32), Bb_(36) and Z_(11)) which inhibited the growth of all tested pathogens. The unusual antibiotic profile of these isolates underlined their-potential as a source of novel antibiotics.
