Cultures require a minimum of 12-18 hours of incubation before reports are made. A. Culture media: Culture media employed for the isolation of common bacteria are shown in Table [...]
In this article we will discuss about the Reactions of Antigen-Antibodies in Bacteria. When an antigen combines with its specific antibody in presence of an electrolyte (NaCl) in an optimum concentration at an optimal pH and temperature (37°C), the antigen and antibody complex forms an insoluble precipitate. Important tests for antigen-antibody reactions include precipitation, agglutination, complement fixation, neutralisation, and labelled [...]
In this article we will discuss about the Bacteriology of Water, Milk and Air. Bacteriology of Water: Introduction: Safe water should be free from microorganisms and chemical substances and drinking water in particular should not only be safe but also pleasant to drink, i.e. cool, clear, colourless and devoid of disagreeable taste or smell. Faecal pollution of water supplies may [...]
