Antimicrobial susceptibility and virulence factors of Enterococci colonizing intestinal tract of infants
Keywords:Fecal enterococci, Infants, Antimicrobial resistance, Virulence factors
Aim: This study investigated distribution of enterococci colonizing intestinal tract of infants and Â has determined their putative virulence factors and antimicrobial susceptibility patterns.Â
Methods: Â A total of 82/186 (44.1%) fecal enterococcal isolates were recovered from infants. All enterococci isolates were identified either E. faecalis or E. faeciumÂ using culture and PCR.
Results: A significant higher intestinal colonization ofÂ enterococci was detected among non-hospitalized compared to hospitalized patients with a percentage ofÂ (72 % vs. 28%), respectively . E.faecalis was the predominant species in both groups (75.6%). It had also significantly higher virulence factors genes than E. faecium ,whileÂ E. faecium had higher rates of antimicrobial resistance than E.faecalis.Â
Conclusion: This study shows significantly higher rate of intestinal colonization of Â E.faecalis than E. faeciumÂ of hospitalized and non-hospitalized infants, and Â E.faecalis carried significantly higher potential virulence genes than E. faecium.
