Chlamydia trachomatis and Neisseria gonorrhoeae are important bacterial pathogens
of sexually transmitted infections (STIs) worldwide. This study sought to compare the analytical
sensitivity and specificity of conventional methods against a rapid molecular method in detecting
STIs caused by these bacteria. Methods: Ninety five first-time male attendees of the Genito-urinary
Medicine Clinic in Hospital Kuala Lumpur were included in this cross-sectional study. The detection
of C. trachomatis was achieved through direct fluorescence antibody (DFA) staining of urethral
swabs and real-time polymerase chain reaction testing (Xpert® CT/NG assay) on urine specimens.
N. gonorrhoeae was detected through Gram staining and culture of urethral swabs and Xpert® CT/
NG assay on urine specimens. Results: From the Xpert® CT/NG results, 11 (11.6%) attendees had
chlamydia, 23 (24.2%) had gonorrhoea and 8 (8.4%) had both STIs. The sensitivity and specificity
of DFA in detecting chlamydia compared to Xpert® CT/NG were 5.3% (95% CI: 0-28) and 94.7%
(95% CI: 86-98), respectively. For gonorrhoea, the sensitivity and specificity of Gram staining were
90.3% (95% CI: 73-98) and 95.3% (86-99), respectively, whereas the sensitivity and specificity of
culture compared to Xpert® CT/NG were 32.2% (95% CI: 17-51) and 100% (95% CI: 93-100),
respectively. Conclusion: Although Gram-stained urethral swab smears are sensitive enough to be
retained as a screening tool for gonorrhoea, culture as well as DFA lack sensitivity and are poorly
suited to screen for gonorrhoea and chlamydia, respectively. However, owing to their high specificity,
conventional detection methods are still suitable as confirmatory tests for gonorrhoea and chlamydia.

Sporotrichosis is a mycosis caused by a saprophytic dimorphic fungus named Sporothrix schenckii. Infections occur following traumatic inoculation of fungus from plants and infected cat bites and scratches. We report a case of a farmer who presented with a solitary subcutaneous nodule initially diagnosed as a soft tissue tumour. A history of agricultural activity and feline contact should draw the clinician's attention to sporotrichosis, as the diagnosis can be easily missed in atypical cases. The diagnosis, microbiology and management of the case are discussed.

Introduction: Carbapenem-resistant Enterobacteriaceae (CRE) is increasingly reported worldwide causing serious
threats to healthcare. This study aimed to identify the common organisms associated with CRE, the clinical characteristics and risk factors for acquiring CRE infection and colonisation among hospitalised patients. Methods: This
is a matched, case-control study. Patients aged 18 years and above whom were hospitalised from January 2019 to
December 2019 and had CRE isolated from clinical specimens were matched with carbapenem-susceptible controls
(CSE), based on gender and age. Univariate and multivariate statistical analysis was performed. Results: Among 184
patients, Klebsiella pneumoniae was the most common organism causing CRE infection and colonisation. Chronic
kidney disease (p=0.025, OR:3.12, 95% CI:1.15-8.41), urinary catheterisation (p=0.005, OR:3.67, 95% CI:1.49-
9.00), prior use of cephalosporin (p<0.001, OR:4.69, 95% CI:1.96–11.22) and beta-lactam combination agent
(p<0.001, OR:7.18, 95% CI:2.98-17.26) were identified as the independent risk factors. Conclusion: Chronic kidney
disease, urinary catheterisation, prior use of cephalosporin and beta-lactam combination agents were independently
associated with CRE infection and colonisation. These findings enable targeting potential CRE cohorts, hence, necessitate early undertaking of prevention measures to delay the onset of CRE. A rigorous effort by antibiotic stewardship
an infection control team are pivotal.
