Question

What is the structure and arrangement for the following unknown bacteria? What is the Gram Stain? Select one: a. Gram negative Streptobacilli b. Gram positive Streptobacilli c. Gram positive Staphylbacilli d. Gram positive Staphylcocci

Answer 1

Dear Scholar ,

The given structure is the Gram negative Streptobaccilli . Gram negative is the bacteria that gives the negative test with the gram stain . The Gram negative bacteria have a thin cell walls of peptidoglycan which donot able to retention of the primary stain that is Genson's violet. The Decoloriser Alcohol do able to Decolorise the primary stain due to thick layer . The Gram negative bacteria have a lipid cytoplasmic membrane . Teichoic acid and lipotechoic acids are present in Low concentration in gram negative bacterias .

They have High protoplasmic content as compared to the gram positive bacteria . The Gram negative bacteria are classified on the Basis of shape that is cocci and bacillus shaped . cocci are spherical in shape whereas the Bacillus are Rod shaped in structure . This Bacteria shown here is rod shaped Hence , bacillus bacteria . Streptococcus bacteria is pleomorphic in nature and it has a filamentous structure. It does not show any motility even with the presence of flagellum . They are non acid fat in nature.  

Hence , option 1 is the correct answer.
