They found that in D. disciodeum thrived equally on nutrient soil and a non-nutrient agar dishes (Bonner & Lamont‚ 2005). Similarly to the experiment preformed

However‚ because new strains continue to emerge‚ it is of the utmost importance that microbiologists and microbiology students understand the nature of each bacterial species and how that species creates and maintains its complex communities.

observed under oil immersion to determine morphology. Upon completion of the basic stain organism appeared to be cocci that was in a line with further help it was determined to be rod shaped. Next we did a negative stain test beginning with a drop of nigrosin stain that we aseptically added the organism to the slide. Afterwards we spread the stain across the slide. Without heat- fixing we dry the slide and observed under microscope observing the morphology of rod shapes which eliminated any

ABSTRACT Nature has been a source of medicinal agents for thousands of years and an impressive number of modern drugs have been isolated from natural sources Plants used for traditional medicine contain a wide range of substances that can be used to treat chronic as well as infectious diseases. Clinical microbiologists have great interest in screening of plants for antimicrobial activities and phytochemicals as potential new therapeutics. The use of plant extract for medical treatments is enjoying
