The catalase reaction
was negative, and the esculin hydrolysis reaction was quickly positive.
With the use of a sterile pick, a sample colony was gathered and was placed in the glass slide with the hydrogen peroxide and was observed for the appearance of bubbles which would indicate a positive catalase reaction
Staphylococcus aureus isolates were identified using colonial morphology, catalase reaction
, and Staphaurex latex testing (Remel, Lenexa, Kansas).
aureus morphology were examined microscopically, gram stained, tested for catalase reaction
and inoculated on Mannitol salt agar and incubated at 35 [degrees]C for 24 h.
Among these 23 isolates, only 4 isolates showed a positive catalase reaction
and the remaining 19 were catalase negative (Table 2).
