Staphylococcus aureus which is gram negative bacteria 2. ... is a type of bacterium with a shape intermediate between cocci (spherical bacteria) and bacilli (rod-shaped bacteria). Mushrooms Bacteria. Coccus refers to the shape of the bacteria, and can contain multiple genera, such as staphylococci or streptococci. Cocci are bacteria that are spherical or ovoid in shape. Bacilli and cocci are important forms of Gram-positive bacteria.
The coccus (plural form is cocci) bacteria are spherical and are usually found in clusters or chains. Spiral. Bacterial morphology deals with size, shape, and arrangement of bacterial cells.Bacteria are microscopic organisms that are less than 3 micrometeres (μm) in size. are representatives of gram-positive diplococci.

E. coli , a large, varied group of bacteria, are found in the environment, intestines and food of humans and animals. Cocci do not dry out as quickly and retain water, but they absorb nutrients slowly. If an individual is infected, antibiotics are a usual first line treatment. Gram negative bacteria on the other hand stain pink and tend to be significantly more resistant. At (4) a bacillus is shown undergoing reproduction by binary fission.
