Summary: | Enterococci are part of normal microbial flora in the gastrointestinal tract of
human and animals. They have emerged to pose a significant public health concern
through its emergence of being opportunistic in causing nosocomial infections as well as
acquiring high level of resistance to many antimicrobial agents. Vancomycin-resistant
enterococci (VRE) appearance has caused serious problems in human and veterinary
medicine. The objectives of this study were to isolate and identify enterococci in cats
exposed to different antibiotics and to determine its antimicrobial susceptibility pattern.
Thirty (30) rectal swabs of cats were collected from a veterinary clinic and processed for
isolation and identification of enterococci by inoculating the samples onto blood agar and followed by biochemical tests. The isolates were then subjected to antimicrobial
susceptibility test (AST) to six antibiotics namely amoxicillin, amoxicillin and
clavulanic acid, enrofloxacin, marbofloxacin, doxycycline, and vancomycin. Six rectal
swab samples were positive for enterococci. The enterococci isolates were consists of E.
faecalis (3 isolates), E. durans (3 isolates) and Enterococcus sp.(1 isolate). None of the
isolates were resistant to all six antibiotics tested. Enterococcus sp. isolate was resistant
to five antibiotics (amoxicillin, amoxicillin and clavulanic acid, enrofloxacin,
marbofloxacin, and doxycycline). One isolates of E. faecalis was resistant to four
antibiotics (amoxicillin and clavulanic acid, enrofloxacin, marbofloxacin, and
doxycycline). One E. faecalisand one E. durans were resistant to three antibiotics
(amoxicillin and clavulanic acid, enrofloxacin, and marbofloxacin). Two E. durans and
one E. faecalis were resistant to two antibiotics (enrofloxacin and marbofloxacin). All
enterococci isolates were resistant to enrofloxacin and marbofloxacin whilst
vancomycin was the antibiotic that all the isolates were sensitive to. Two multi drug
resistant (MDR) enterococci and two extensively drug resistant (XDR) enterococci were detected in this present study. |
