Classification of Bacteria

Classification of Bacteria on the Basis of Shape

Classification of Bacteria Bacteria are classified and identified to distinguish one organism from another and to group similar organisms by criteria of interest to microbiologists or other scientists. The classification of bacteria serves a variety of different functions. Because of this variety, bacteria may be grouped using many different typing schemes. The grounds for the classification commonly used may be: Morphologic Characteristics Both …

Cultural and Biochemical characteristics of Staphylococcus aureus

Cultural characteristics of Staphylococcus aureus Staphylococci grow readily on most bacteriologic media under aerobic or microaerophilic conditions. Colonies on solid media are round, smooth, raised, and glistening. S. aureus usually forms gray to deep golden yellow colonies. Mannitol Salt Agar: circular, 2–3 mm in diameter, with a smooth, shiny surface; colonies appear opaque and are often pigmented, golden yellow.  Tryptic Soy …
