A Gram stain of mixed Staphylococcus aureus (S. aureus ATCC 25923, gram-positive cocci, in purple) and Escherichia coli (E. coli ATCC 11775, gram-negative bacilli, in red), the most common Gram stain reference bacteria. Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups ...
Rod-shaped gram-positive Bacillus anthracis bacteria in a cerebrospinal fluid sample stand out from round white blood cells, which also accept the crystal violet stain. Violet-stained gram-positive cocci and pink-stained gram-negative bacilli. In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain ...
Staphylococci spp. are a genus of gram positive cocci of 0.5 - 1 μm diameter. [citation needed] Staphylococcus pseudintermedius is a non-motile and non-spore forming, facultatively anaerobic bacterium. [citation needed] It appears primarily as grape-like clusters morphologically, but can also be seen as individual or paired cocci.
The Gram stain results inform microbiologists about what types of agar plates should be used and what tests might be appropriate to identify the organism. [60] In some cases, no organisms are seen on the Gram stain despite the culture bottle showing indicators of growth or being reported as positive by automated instruments.
The process or results are called a WBC differential. This test is useful because many diseases alter the proportion of certain white blood cells. By analyzing these differences in combination with a clinical exam and other lab tests, medical professionals can diagnose disease. One commonly recognizable use of differential staining is the Gram ...

A Gram stain is performed to show Gram-positive cocci in chains. Then, the organism is cultured on blood agar . The rapid pyrrolidonyl arylamidase (PYR) test is commonly used, wherein a positive reaction confers a presumptive identification of group A beta-hemolytic streptococci if the appearance and clinical context is consistent.
