| The most common pathogens were coagulase negative staphylococci, escherichia coli, and Staphylococcus aureus. |
| Then followed by the specific biochemical test for Staphylococcus aureus such as catalase and coagulase tests were carried out. |
| Bacterial culture of biopsy specimens grew few coagulase negative staphylococci, while fungal, viral, and legionella cultures of the specimens were all negative. |
| Gram positive organisms including the coagulase negative staphylococci and the viridans streptococci are the most commonly isolated. |
| The clinical presentation of systemic infection, particularly with coagulase negative staphylococci, can be insidious. |
| In the case of Gram positive cocci, we did a catalase test followed by, for example, a coagulase test or an optochine test. |
