To examine microgravity’s impact on bacterial antibiotic resistance, scientists are set to ship E. coli, a typical bacterial pathogen linked to urinary tract infections and foodborne diseases, to the International Space Station (ISS). The E. coli AntiMicrobial Satellite (EcAMSat) mission is scheduled to launch to the ISS on Orbital ATK’s Cygnus cargo spacecraft on Saturday together with a slew of different science experiments and provides for the Expedition 53 crew, reported.

Antibiotic resistance might pose a hazard to astronauts, particularly since microgravity has been proven to weaken human immune response, NASA mentioned. The E. coli AntiMicrobial Satellite mission will examine spaceflight results on bacterial antibiotic resistance and its genetic foundation. The experiment will expose two strains of E. coli, one with a resistance gene, the opposite with out, to a few totally different doses of antibiotics, then look at the viability of every group.

“Results from this investigation could contribute to determining appropriate antibiotic dosages to protect astronaut health during long-duration human spaceflight and help us understand how antibiotic effectiveness may change as a function of stress on Earth,” NASA mentioned. Rather than being housed contained in the area station, this experiment will happen in a 6U cubesat, a small satellite tv for pc that has six instances the quantity of a single cubesat.

The basic situation of the experiment protocol will begin 4 days after launch of the EcAMSat satellite tv for pc by permitting an preliminary progress after which hunger interval for E. coli micro organism contained in 48 microfluidic wells. The investigation goals to find out “the lowest dose of antibiotic needed to inhibit growth of Escherichia coli (E. coli), a bacterial pathogen that causes infections in humans and animals,” NASA officers wrote in an outline of the experiment.
