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).
Lactobacilli were identified by standard methods including characteristic Gram stain morphology after growth on agar media (incubated aerobically and anaerobically), and a negative catalase reaction
