| Gram positive organisms including the coagulase negative staphylococci and the viridans streptococci are the most commonly isolated. |
|
| In the case of Gram positive cocci, we did a catalase test followed by, for example, a coagulase test or an optochine test. |
|
| The clinical presentation of systemic infection, particularly with coagulase negative staphylococci, can be insidious. |
|
| The most common pathogens were coagulase negative staphylococci, escherichia coli, and Staphylococcus aureus. |
|
| Bacterial culture of biopsy specimens grew few coagulase negative staphylococci, while fungal, viral, and legionella cultures of the specimens were all negative. |
|
| Bacteria exhibiting a catalase positive reaction were examined further by the coagulase test to differentiate the potential of Staph. |
|
| The most common cause of infections was a bacteria that lives on the skin called coagulase negative staphylococci. |
|
| Then followed by the specific biochemical test for Staphylococcus aureus such as catalase and coagulase tests were carried out. |
|
| There was no evidence of a pathogenic infection in the wound, as cultures yielded only 'normal skin flora', which included coagulase negative Staphylococcus and diphtheroids. |
|
| Coagulase negative staphylococci, alpha hemolytic streptococci, diphtheroids, and Bacillus species other than Bacillus anthracis were considered as possible contaminants. |
