ANTIBIOTIC EXTRACT OF STREPTOMYCETES IN PATHOGEN BACTERIA

Streptomycetes usually inhabit soil and are important decomposers. They also produce more than half of the world s antibiotics, and are consequently invaluable in the medical field. The isolation of Streptomycetes has done for testing the antibiotic effect. In this study are used two kinds of soil from the locality of village Zhur, South of Kosova. Five extracts have been isolated. From the obtained samples the substance has been extracted, and it was tested in order to define the scale of inhibition for the development of some microbial cultures. Escherichia coli, Staphylococcus aureus and Pseudomonas have been chosen as testing cultures. The extraction of substances with microbial properties has been done by means of Augustine et al’s method while the test of the obtained extract has been done according to the gel diffusion method. The inhibition zones have been established as well. Thus we may suppose that those results will encourage further researches in this field in the other localities of Kosova
