Post COVID-19 opportunistic candida retinitis: A case report

A 42-year-old male patient presented with profound impairment of vision in both eyes, just as he was recovering from COVID-19. A known diabetic and hypertensive, he suffered from COVID-19 pneumonia further complicated by ARDS, septicaemia and acute kidney injury. His vision on presentation was finger counting close to face bilaterally with multiple, yellowish lesions at the posterior pole. Based on the clinical findings and previous blood culture report, it was diagnosed as candida retinitis and…

Environmental Candida auris and the Global Warming Emergence Hypothesis

Global warming was proposed to be a contributing cause for the nearly simultaneous emergence of different clades of Candida auris as a nosocomial pathogen in different continents. The global warming emergence hypothesis posits that C. auris existed in the environment prior to its clinical recognition and became pathogenic for humans because of thermal adaptation in response to climate change. The isolation of C. auris from two sites in the remote Andaman Islands establishes it as an…

Clinically isolated bacteria resistance to silver-based wound dressings

CONCLUSION: Our findings provide additional evidence that clinically significant silver-resistance has emerged in the clinical setting. Such resistant microbes are capable of sustained silver resistance against a wide variety of silver adjuvants. These findings suggest that the further development and dissemination of these resistance mechanisms could significantly impact current practices in wound healing.

The increasing problem of treatment-resistant fungal infections: a call for antifungal stewardship programs

Antimicrobial stewardship (AMS) programs have been widely recognized among the public health community. These programs focus majorly on bacterial infections, efficient antibiotic use, and measures to curb increasing antibacterial resistance. AMS programs are successfully established around the globe; however, very few include antifungal stewardship (AFS). The increasing incidence of superficial and invasive fungal infections, combined with delayed or inaccurate diagnosis, has contributed to the…

Development of a Fast Raman-Assisted Antibiotic Susceptibility Test (FRAST) for the Antibiotic Resistance Analysis of Clinical Urine and Blood Samples

Human health is at great risk due to the spreading of antimicrobial resistance (AMR). The lengthy procedure of conventional antimicrobial susceptibility testing (AST) usually requires a few days. We developed a fast Raman-assisted antibiotic susceptibility test (FRAST), which detects single bacterial metabolic activity in the presence of antibiotics, using Raman single-cell spectroscopy. It was found that single-cell Raman spectra (SCRS) would show a clear and distinguishable Raman band at the…
