Abstract
Beaches are recreational spots for people. However, beach sand contains harmful microbes that affect human health, and there are no established methods for either sampling and identifying beach-borne pathogens or managing the quality of beach sand.This study was conducted with the aim of improving human safety at beaches and augmenting the quality of the beach experience. Beach sand was used as a resource to isolate bacteria due to its distinctive features and the biodiversity of the beach sand biota. A selected bacterial isolate termed FSRS was identified as using 16S rRNA sequencing and phylogenetic analysis, and the sequence was deposited in the NCBI GenBank database under the accession number MF599548. The isolated bacterium was cultured in Luria-Bertani growth medium, and a crude extract was prepared using ethyl acetate to examine the potential pathogenic effect of on human skin. A human skin keratinocyte cell line (HaCaT) was used to assess cell adhesion, cell viability, and cell proliferation using a morphological analysis and a WST-1 assay.The crude extract inhibited cell adhesion and decreased cell viability in HaCaT cells. We concluded that the crude extract of FSRS had a strong pathological effect on human skin cells.Beach visitors frequently get skin infections, but the exact cause of the infections is yet to be determined. The beach sand bacterium may, therefore, be responsible for some of the dermatological problems experienced by people visiting the beach.
