Enzymatic modification results in high-level resistance to aminoglycoside (HLAR), which eliminates the synergistic bactericidal effect of combined exposure to a cell wall-active agent and an aminoglycoside.
So aim of the study was to determine prevalence of HLAR enterococcal isolate and to study distribution of aminoglycoside modifying enzyme genes in them.
A total of 100 nonrepeat isolates of enterococci from various clinical samples were analyzed.
As per Clinical and Laboratory Standards Institute guidelines enterococci were screened for HLAR by Kirby-Bauer disc diffusion method.
Minimum inhibitory concentration of all isolates for gentamicin and streptomycin was determined by E-test.
Multiplex polymerase chain reaction (PCR) was carried out for HLAR enterococcal isolates to identify aminoglycoside modifying enzymes genes responsible for resistance.
60% isolates were found to be high-level gentamicin resistant (HLGR) whereas 45% isolates were found to be high-level streptomycin resistant (HLSR).
By multiplex PCR 80% HLGR isolates carried bifunctional aminoglycoside modifying enzyme gene aac(6′)-Ie-aph(2′′)-Ia whereas 18 out of 45 high-level streptomycin resistant, that is, 40%, isolates carried aph(3′)-IIIa.
However, aph(2′′)-Ib, aph(2′′)-Ic, aph(2′′)-Id, and ant(4′)-Ia genes which encode other aminoglycosides modifying enzymes were not detected.
Bifunctional aminoglycoside modifying enzyme gene aac(6′)-Ie-aph(2′′)-Ia is the predominant gene responsible for HLAR.
