Washington: NASA is concerned about the strains of Enterobacter bacteria identified in the toilet space of the International Space Station (ISS), which can increase potential health effects for future missions, according to American space agency scientists.
A study of the NASA's Jet Propulsion Laboratory (JPL) and the California Calcium Institute (Caltech) revealed 5 Enterobacter bacteria strains isolated from the space lavatory and training in the MSS on March 2015.
Genome sequencing of the samples found that all five strains belong to one species: Enterobacter bugandensis (E.bugandensis).
Although not pathogenic to humans, E. Bagnendis was associated with patients and newly born patients admitted to three different hospitals (East Africa, Washington, and Colorado).
Nitin Singh, the lead author of NASA-JPL Caltech, says: "We have found that for this EOD genome of EBugandensis, taking into account the results of many drug resistance and pathogenicity, it is highly probable.
"However, it is important to understand that the strains found in the ISSs are not harmful, that is, they do not endanger the health of the person, but it is a control," he said.
For a study published in the BMC Microbiology, the group compared MCC strains to all open genomes of 1,291 Enterobacter strains collected on the Earth.
They found that ISS insulators possess antimicrobial resistance patterns similar to three clinical strains found on the Earth and include 112 virulence, disease and defensive gene.
Using computer analysis, they suggested 79 percent probability that they could cause disease.
"The pathogenic pathogens E.Bugandensis causes disease and what dangers it causes," says Casillis Wendzweswan, Senior Researcher at JPL.
"Further in vivo research is needed to determine if IFC events, for example, microgravity, and other space and space-related factors could potentially affect pathogenicity and virulence," he said.
