Emergence of multi-drug-resistant, vancomycin-resistant, and multi-virulent Enterococcus species from chicken, dairy, and human samples in Egypt.

Aims: The present study aimed to detect the frequency of vancomycin resistance and virulence genes' profiles of multi-drug-resistant (MDR) enterococcal isolates from different sources and to investigate the sequence heterogeneity between the esp genes of MDR and vancomycin-resistant Enterococcus faecalis isolates from chicken and human sources.

Methods And Results: Conventional phenotypic methods identified 91 isolates (60.7%) as Enterococcus species, and these isolates were retrieved from dairy (37/52), chicken (35/54), and human (19/44) origins.
