Mastitis is one of the costliest diseases affecting the livestock and incurs huge production losses and also involves high cost of treatment. Milk samples were obtained from the suspected mastitis animals from different parts of the Krishna district. Milk samples collected from different areas and sources were put to mastitis field surf test, white side test. Then the samples found positive were cultured on tryptose agar, MacConkey’s agar and blood agar. The cultures thus obtained were subjected to antibiotic sensitivity test (Disc diffusion method) using 10 commonly used antibiotics in the field to determine the antibiogram....
As plant grows, roots release large quantity of metabolites from living root hairs or fibrous root system. These metabolites act as chemical signals for Rhizobacteria to move to the root surface. And variety bacteria colonize in rhizosphere. Some of the bacteria that inhabit in this area that able to colonize very efficiently in roots or the rhizosphere soil as a bio-film and these bacteria promote the growth of plant. These bacteria are referred to as plant growth promoting rhizobacteria (PGPR). The phytohormones are very important in plant growth and development because they regulate numerous biological processes from cell division, elongation and differentiation to tropic responses, food development and senescence. Auxins induce cell division, cell elongation, rooting callus formation, flowering and so on. Naturally occurring substances with indole nucleus possessing growth-promoting activity are referred to as auxins; chemically it is Indole acetic acid. (IAA) Not only plants but also microorganisms can synthesize phytohormone like auxins and cytokinins. The ability to synthesize phytohormone is widely distributed among rhizobacteria. 80% of the bacteria isolated from plant rhizosphere produce IAA....
Antioxidant and antimicrobial activities play an important role as a major factor regarding health protection. It has been proved through different scientific verification that these activities reduce the risk for various chronic diseases. The beneficial factors which are responsible for the existence of these activities are mainly plant derived compounds known as “Phytochemicals”. Holy basil also known as “Queen of herbs” is a treasure of phytochemicals possessing strong antioxidants which protects the cells from being damaged by free radicals and along with that are also effectual against numerous pathogenic diseases caused due to bacteria, microbes etc. Regarding the essential properties the present paper outlines the study of antioxidant and antimicrobial activity of different species of holy basil and its advantageous effects on various diseases....
