A parasitic bacteria contaminated her food.
Rationale: Her symptoms (nausea, fever, diarrhea) after travel are consistent with a pathogenic (parasite-like) microbe acquired from contaminated food. Parasitic/pathogenic bacteria cause illness in a host, whereas mutualistic or commensal organisms do not typically produce these harmful symptoms, and predation on normal flora wouldn’t explain acute gastrointestinal infection.
