Article Synopsis
  • Mangrove ecosystems are facing threats from climate change and urban pollution, leading to the emergence of potentially harmful yeasts, as studied in Hong Kong's mangroves.
  • The researchers collected water and sediment samples, identifying 45 yeast isolates from 18 species, with a significant presence of pathogenic yeasts known for drug resistance.
  • The study highlights the urgent need for surveillance and collaboration among various disciplines to manage the risks posed by these pathogens, emphasizing the broader public health implications of unchecked urban development in coastal areas.

Introduction: is a Gram-negative, rod-shaped bacterium belonging to the family of , a common pathogen in aquaculture animals, However, studies on its impact on (mud crabs) are limited. In this study, we isolated SWS from dead mud crab during a disease outbreak in a Hong Kong aquaculture farm, which caused up to 70% mortality during summer.

Methods: Experimental infection and histopathology were used to investigate the pathogenicity of SWS in and validate Koch's postulates.

Spectroscopic single-molecule localization microscopy (sSMLM) simultaneously provides spatial localization and spectral information of individual single-molecules emission, offering multicolor super-resolution imaging of multiple molecules in a single sample with the nanoscopic resolution. However, this technique is limited by the requirements of acquiring a large number of frames to reconstruct a super-resolution image. In addition, multicolor sSMLM imaging suffers from spectral cross-talk while using multiple dyes with relatively broad spectral bands that produce cross-color contamination.
