We investigated the antibiotic susceptibility of glycopeptide-resistant enterococci (GRE). Seventy consecutive GRE were tested. Sixty-two isolates were identified as Enterococcus faecium (88.6%), and 8 (11.4%) as Enterococcus faecalis. All strains were susceptible to linezolid and daptomycin, while 17.1% (12/70) and 11.4% (8/70) were resistant to quinupristin/dalfopristin (QD) and tigecycline, respectively. All E. faecalis isolates were resistant to QD, while 4 of 62 (6.5%) E. faecium isolates were resistant to QD. All E. faecalis isolates were susceptible to tigecycline, while 14.5% (9/62) E. faecium isolates were resistant. Continued surveillance of GRE antibiotic susceptibilities is important for combating these multi-resistant nosocomial pathogens.

Aims:
Linezolid has become a decisive therapy in treating infections with vancomycin-resistant Enterococcus (VRE).
Currently, the emergence of linezolid-resistant Enterococcus further complicates the therapeutic options and leads to
global health threat not only in hospital setting but in the community. The study aimed at antimicrobial pattern of
Enterococcus isolated from 6 poultry farms in Kelantan, Malaysia.
Methodology and results:
Between February and December 2019, 300 broiler cloacal swab sample (Gallus gallus
domesticus) were collected and screened for linezolid-resistant enterococci (LRE) using a standard biochemical and
antimicrobial susceptibility tests. Among all the samples, 32.3% (n=97/300) grew Enterococcus, 71.1% (n=69/97) of it
were identified Enterococcus casseliflavus by molecular identification, whilst remaining isolates 28.9% (n=28/97) were
further identified as Enterococcus gallinarum by 16S rRNA sequencing. None of the isolates were found to exhibit high-level resistance to vancomycin. However, 3/97 (3.1%) were exhibit resistance to high-level gentamicin based on Kirby-Bauer disk diffusion test. Whereas 48/97 (49.5%) of isolates were observed to be resistant to ampicillin, 28/97 (28.9%)
were resistant to penicillin. Surprisingly, among the two strains isolated, 18.6% (n=18/97) of it were resistant to linezolid.
Isolates showed resistance to linezolid by disk diffusion test were verified by VITEK-2 automated system (bioMérieux,
USA) with MIC ≥8 µg/mL. All antimicrobial susceptibility test and minimal inhibitory concentration (MIC) results were
interpreted according to Clinical and Laboratory Standard Institute (CLSI).
Conclusion, significance and impact of study
In conclusion, this study has reported the prevalence of linezolid
resistant Enterococcus (LRE) in highly intrinsic antibiotic resistant of E. casseliflavus and E. gallinarum in Malaysia
poultry farms, alongside with the truancy of vanA strains. The emergence of LRE strains is an alarming problem to the
animal husbandry and healthcare setting worldwide. This could lead to potentially untreatable and life-threatening
enterococcal infections. Even more worrying is the spread of LRE to geographical regions where these strains were
previously unreported, which may pose a global health threat. Antimicrobial surveillance in poultry husbandry is thus,
dimly necessary to prevent wide spread of multidrug-resistant bacteria.

The purpose of this study was to observe the effect of canal filling on the bacteria left in the dentinal tubules and to compare the sealing ability between Gutta-percha and Resilon. The bovine dentin block models were prepared. E. faecalis was inoculated to dentin blocks and incubated. The dentin blocks were divided into 5 groups. Group 1 was the negative control. Group 2 was the positive control. Group 3 was filled with ZOE based sealer and Gutta-percha, Group 4 with resin based sealer and Gutta-percha, and Group 5 with resin based sealer and Resilon. After 24 hour, the blocks were incubated at 37degrees C for 1, 2, 3 and 4 weeks on BHI agar plates. The internal dentin portion of the blocks was removed using ISO 027, 029, 031, 035 round burs and the dentin chips were incubated at 37degrees C for 24 hour. Following incubation, the optical density of the medium was measured. The data were statistically analysed using repeated measures ANOVA and one-way ANOVA. The results were as follows, 1. There was statistically significant reduction in the number of E. faecalis of the group where dentinal tubules were completely sealed with nail varnish in comparison with the groups obturated with gutta-percha or resilon (p < 0.05). 2. In group 5, the number of E. faecalis in the dentinal tubules decreased significantly with time (p < 0.05), whereas in Group 3 and 4, there was no reduction in its number (p > 0.05). 3. Under the conditions of this experiment, E. faecalis survived up to 4 weeks after obturation with gutta-percha or resilon (p > 0.05).
