A total of 120 enterococci
isolated from food and animal fecal samples were used in this study (Table 1).
The prevalence of Enterococci
with a higher resistance level in a tertiary care hospital: a matter of concern.
This study was conducted to determine the rate of HLAR and the distribution of AME genes in enterococci
isolated from patients with hospital acquired UTI at Mansoura University Hospitals in Egypt.
This finding is consistent with the results of a study conducted in 2009 in Iran by Behnoud et al., (30) who reported that 32.43% of their enterococci
cases were resistant to HLGR.
The ubiquitous distribution of the genus as intestinal flora, the widespread use of broadspectrum antibiotics and invasive devices are known to be the major factors contributing to the emergence of enterococci
as important pathogens.
Lebreton has been investigating the evolution of enterococci
from its commensal Paleozoic origins its rise as a hospital threat.
Evidences showed that previous administration of antibiotic treatment, concurrent infections, surgery, catheterizations, duration of hospital stay, presence of pervious hospitalization, and underlying diseases like cancer, HIV, and diabetics are among the risk factors associated with the spread of enterococci
infections [4, 7, 8].
The isolates of enterococci
were identified and speciated on the basis of colony morphology, Gram stain, and various biochemical reactions such as catalase test, bile esculin test (as shown in Figure 1), growth in 6.5% NaCl, PYR test, mannitol fermentation, arginine dihydrolase test, sucrose fermentation, arabinose fermentation, growth in pyruvate, lactose fermentation, and pigment production.
