News Excerpt:
Researchers from the Indian Institute of Technology Madras (IIT-M) and NASA's Jet Propulsion Laboratory (JPL) have conducted a joint study examining the behaviour of multi-drug resistant pathogens on the International Space Station (ISS).
What is a Superbug?
- A superbug may be a bacteria, virus, parasite, or fungi that have become resistant to multiple drugs typically used to treat these infections.
- Superbugs can't be stopped by first line of drugs.
- This resistance makes infections caused by superbugs particularly difficult to treat and control. The development and spread of superbugs pose a significant public health threat worldwide.
- Superbug infections can lead to higher rates of death from otherwise treatable diseases.
More about this research:
- Research on Enterobacter bugandensis offers potential for improving hospital infection management and enhancing astronaut health.
- The study focused on the genomic, functional, and metabolic adaptations of Enterobacter bugandensis, a pathogen known for its resistance to third-generation cephalosporins and quinolones.
- These adaptations make Enterobacter infections particularly challenging to treat.
- Enterobacter species are part of the ESKAPE group of pathogens, which the World Health Organization (WHO) has identified as a priority for developing new antimicrobials.
Experiment environment and methodology
- The researchers investigated the mechanisms that enable Enterobacter bugandensis to thrive in the unique environment of the International Space Station (ISS).
- The ISS, with its microgravity, heightened carbon dioxide levels, and increased radiation, provides a distinctive setting for studying microbial dynamics.
- Researchers isolated 13 strains of E. bugandensis from various surfaces within the ISS. These strains exhibited accelerated mutations, making them genetically and functionally distinct from their Earth counterparts.
- Strategies for controlling microbial contamination in enclosed spaces like spacecraft and hospitals can be guided by understanding the persistence and succession patterns of E. Bugandensis in space, according to the research.
Implications for Healthcare and Space Exploration
Researchers emphasized the dual importance of this research.
Healthcare:
- The pathogenic potential of microorganisms in space environments mitigates the risks associated with opportunistic pathogens in closed human-built environments on Earth.
- Understanding these adaptations is crucial given the formidable challenges posed by multi-drug-resistant pathogens in healthcare settings.
Impact on Space Exploration:
- The presence of multi-drug resistant pathogens aboard the ISS adds a new layer of complexity to health and safety protocols for astronauts.
- Because of their altered immune systems and restricted access to healthcare facilities, astronauts face particular health difficulties in space.
- To assess the ISS's influence on astronaut well-being, the researchers said it is essential to understand the microbiological environment there.
- This research underscores the need for robust preventive measures to ensure the health and safety of astronauts, who operate under altered immune conditions with limited access to medical facilities.
Applications:
- The study's findings have promising applicability in controlled Earth environments, including critical care units in hospitals, where multidrug-resistant pathogens pose serious problems.
- Comprehending the genetic modifications of multidrug-resistant E. Bugandensis can aid in the development of focused antimicrobial treatments.
