In a recent study focused on life aboard the International Space Station, scientists have identified microbes from fourteen different species that live there alongside astronauts. This research is important because it helps us understand how these tiny organisms can affect our health in space where we cannot easily escape their presence or get fresh air and water like here on Earth. The study found out more about the "micro-biome" of the ISS, which includes all living things too small to see with just your eyes - bacteria, viruses, fungi, etc., that live in a closed environment where they can grow without being disturbed by natural elements. This is crucial because changes or new microbes could make astronauts sick since their immune system works differently when it's not on Earth due to the lack of gravity and other factors (1). By keeping an eye on these tiny life forms, researchers can track how they evolve over time. This helps ensure that any harmful germs don't become a bigger problem for astronauts living in space - where getting medical help isn't as easy or quick as it is back home (2).
In this research paper, scientists conducted a comprehensive study to characterize microbial species present on International Space Station (ISS) surfaces during the "Microbial Tracking 2" investigation. The primary objective was to monitor and understand the spread and evolution of secondary pathogens within closed habitats in space-an environment where human immune function is compromised due to prolonged exposure to microgravity, as previously reported (1). Methodology: To achieve this goal, researchers collected samples from various ISS surfaces during routine maintenance activities. These specimens were then subjected to a series of molecular and phenotypical analyses aimed at identifying the species present on these unique habitats in space. The study employed advanced sequencing techniques such as 16S rRNA gene amplicon sequencing, metagenomic shotgun sequencing, and bioinformatics tools to identify a total of 14 distinct microbial taxa that were isolated from the ISS surfaces during this investigation (2). Key Findings: The study revealed an unexpectedly high diversity of bacteria on International Space Station's habitats.
