Abstract
Antibiotic resistance emergence in a closed habitat poses existential risk to the community. With a finite formulary and no possibility of same-day resupply, a resistant organism could render an entire antibiotic class ineffective before replacement drugs arrive. We present antibiotic stewardship protocols adapted for the lunar closed-habitat context.
Standard antibiotic stewardship principles — reserve broad-spectrum agents, rotate classes, obtain cultures before treatment — apply with heightened urgency in a closed lunar habitat. A community of 50 people sharing air, water, and food represents an ideal ecosystem for resistance propagation.
Our protocols were developed after a near-incident at Shackleton Base in 2027: a urinary tract infection treated empirically with ciprofloxacin was later found to involve a fluoroquinolone-resistant E. coli strain. Had this organism spread to the water supply, the habitat's entire fluoroquinolone supply would have been rendered ineffective.
Key protocols: mandatory culture before empirical treatment when patient stability allows, 48-hour de-escalation review for all broad-spectrum agents, biannual resistance profiling of habitat microbiome, and strict antibiotic inventory reserve with Earth resupply triggers.
The philosophical framing matters: in a closed habitat, antibiotic prescribing is a community act, not just a clinical one. Every unnecessary broad-spectrum course degrades the shared therapeutic commons. TANSTAAFL applies — there ain't no such thing as a free antibiotic course.
