| In the case of Gram positive cocci, we did a catalase test followed by, for example, a coagulase test or an optochine test. |
| The elongation phase of growth distinguishes bacilli from cocci, which grow and divide by pure septation. |
| Pathologic examination of the specimen revealed an organizing abscess with numerous bacterial cocci. |
| The four cocci which result from a single division may remain together, giving the tetracoccus or tetrad grouping. |
| Major and limb-threatening infections may involve aerobic gram positive cocci, gram negative bacilli, anaerobes, and enterococci. |
