These include pollution of large water resources‚ destruction of microorganisms‚ acidity of the soil and reduction in soil fertility etc. In recent years scientists have found an alternative way to deal with this deleterious effect of chemical pesticides. Currently‚ there is a great interest in the field of bacterial interactions

the difference between sterilization and disinfection? Control of growth refers to the prevention of growth of microorganisms. This control is affected in two basic ways: by killing microorganisms or by inhibiting the growth of microorganisms. Control of growth usually involves the use of physical or chemical agents which either kill or prevent the growth of microorganisms. Agents that kill cells are called cidal agents; agents that inhibit the growth of cells without killing them are called

setting. The goals of aseptic technique are to protect the patient from infection and to prevent the spread of pathogens. Often‚ practices that clean (remove dirt and other impurities)‚ sanitize (reduce the number of microorganisms to safe levels)‚ or disinfect (remove most microorganisms but not highly resistant ones) are not sufficient to prevent infection.

Habes‚ and Avdic 3885). Recently though‚ the microorganism is becoming the common cause of nosocomial infections. In “Microbiology: with diseases by taxonomy”‚ Richard Bauman defines a nosocomial infection as “a disease acquired in a healthcare setting.” These infections are often found with implants and plastic items that have inserted into the body‚ such as catheters‚ pacemakers‚ and urinary catheters (Avdic‚ et. al 3885). “The ability of this microorganism to causes infections is primarily due to
