Vancomycin resistance among Enterococcus isolates.

Among hospitalized patients, E. faecium has the highest resistance rate to vancomycin (86.5 %), while E. avium has the lowest resistance rate (16.7 %) (P= 0.016).

Among non-hospitalized individuals, E. faecium has the highest resistance rate to vancomycin (55.6), while E. durans has the lowest resistance rate (33.3%), (P = 0.387). Table (4.4) illustrates the vancomycin susceptibility patterns of various Enterococcus species isolated from both hospitalized patients and non-hospitalized.
