E.g:Morphine,codeine etc.Antimicrobials:The chemical substances which destroy (or) prevent the development (or)inhibit the pathogenic action of microbes such as bacteria,fungi,virus are called antimicrobials.E.g,:Lysozyme,Lactic acid etc., Antibiotics:The chemical substances produced by micro organisms and inhibit the growth or destroy microorganisms are called antibiotics. (or) The substance produced totally or partly by chemical synthesis in low concentration inhibits the growth (or) destroy microorganism by chemical synthesis in low concentration inhibits the growth (or) destroy microorganism by intervening in their metabolic process are called antibiotics.E.g:Penicillin chloramphenicol etc. Antiseptics:The chemical, compounds that kill (or) prevent the growth of micro organism are called antoseptics.Antiseptics are the chemical substance apllied on the living tissues such as wounds,cuts ulcers and diseased skin surfaces. Disinfectants:The chemical compounds used for killing (or) preventing the growth of microorganism are called disinfectants. These are apllied to inanimate object like floors,drainage systems etc.ltbergt E.g: i) 4% aqueous of formaldehyde called formalin is a disinfectant ii)0.3 ppm chlorine aqueous solution is disinfectant. iii)`SO_(2)`in very low concentration is disinfectant.

Passage 2 Antibiotics are the chemical substances which are produced by microorganisms like bacteria, fungi and moulds. Antibiotics can inhibit the growth or even destroy other microorganisms. Now-a-days, synthetic antibiotics are also available. The first successful antibiotic produced was penicillin. The antibiotics may be either bacteriocidal (kills the organism in the body) or bacteriostatic (inhibits the growth of organism). Ampicillin and amoxycillin are modified antibiotics. Broad spectrum antibiotics are effective against several types of harmful microorganisms. Answer the following questions : 1.Chloramphenicol is :A. antipyreticB. broad spectrum antibioticC. azo dyeD. tranquillzer |
