Resistance to antifungal agents has increased in Candida spp., especially in non-albicans species. Recent findings reported a strikingly low susceptibility in Candida spp. towards itraconazole in Malaysia. In this study, a colorimetric broth dilution method was utilized to determine the susceptibility of Candida spp. isolated in Kuala Lumpur Hospital within a six month period. A total of 82 isolates from blood, peritoneal and other fluids were tested against 8 antifungal agents using the Sensititre Yeast One method. These comprised of 32 (39%) C. albicans, 17 (20.7%) C. glabrata, 15 (18.3%) C. tropicalis, 13 (15.9%) C. parapsilosis, two (2.4%) C. sake and 1 (1.2%) each of C. pelliculosa, C. rugosa and Pichia etchellsii/carsonii. Overall, susceptibility of all isolates to caspofungin was 98.8%, amphotericin B, 97.6%; 5-flucytosine, 97.6%; voriconazole, 97.6%; posaconazole, 87.8%; fluconazole, 82.9%; ketoconazole, 79.3%; and itraconazole, 56.1%. A total of 18 Candida spp. isolates (22 %) were resistant to at least one antifungal agent tested, and half of these were resistant to three or more antifungal agents. C. glabrata was the most frequently identified resistant species (10 isolates), followed by C. tropicalis (4 isolates), C. parapsilosis (3 isolates) and C. albicans (1 isolate). Resistance was highest against ketoconazole (20.9%), followed by itraconazole (13.4%). However, 30.5% of isolates were susceptible-dose dependent towards itraconazole. Long-term usage of itraconazole in Malaysia and a predominance of nonalbicans species may account for the results observed in this study. In conclusion, susceptibility to antifungal drugs is species-dependent among Candida spp.; reduced susceptibility to itraconazole is concomitant with the high number of non-albicans Candida species isolated in Malaysia.

Vancomycin-resistant Enterococcus faecium (VREF) in
human infections mostly belong to the high-risk, epidemic,
clonal complex-17 (CC17) group. Treatment limitation and
high conjugation frequency makes it dominant in hospitals
worldwide. We investigated positive cultures by Pulse-field
gel electrophoresis (PFGE), multi locus sequence typing
(MLST). DNA of two strains (A2 and C) appeared to be
clonally related by PFGE. Three strains were of ST 18 type
(A1, B and C) and strain A2 is of a new ST 596. This ST 18
type strain found in our study is crucial and is believed to be the first in Malaysia.

Introduction: Sexually transmitted Infections (STIs) are major public health concerns reaching an all-time high, globally. In Malaysia data on the prevalence of STIs remains scarce which limits the understanding of STI transmission
dynamics and the role of interventions in the control of STIs. The aim of this study is to determine the epidemiology
characteristics of STIs mainly from Malaysian private healthcare institutions. Method: A two years (2016 and 2017)
retrospective review was conducted on 160 multiplex RT-PCR STI reports from KPJ hospitals, Malaysia. Results:
There were 65 (40.6 %) patients positive STIs [male: 21/65 (32.3 %); female: 44/65 (67.7 %)]. The STIs was prevalent among young adults (56/65; 86.2 %) from the central region (46/65; 70.8 %). Females had 1.7 times greater risk
to develop STI (20 per 100) and two times higher chance to have multiple STIs (10 per 100) in comparison to male.
The single STIs was caused mainly by U. parvum (N=17). In males, U. urealyticum (N=3) and C. trachomatis (N=3)
were prevalent, while U. parvum (N=15) was prevalent in females. There were 19 dual infections of STIs which were
commonly caused by U. parvum and M. hominis (N=5). There were seven STIs cases caused by three pathogens
concurrently including U. urealyticum, U. parvum and C. trachomatis (N=2) and U. urealyticum, M. genitalium
and C. trachomatis (N=2). Females from urban communities have higher risk in comparison to males for developing
multiple STIs. Conclusion: This study provides an imperative platform for temporal trends of STIs in Malaysia which
reflects the health status of certain populations that warrant immediate public health interventions.
