Description
Parany and colleagues studied black rat genetics in a plague area of Madagascar in a 2026 paper. Rats carry the plague germ in the highlands, where the disease still returns. Nearly five hundred rats from six villages were sampled indoors and outdoors across two years and tested at many gene markers.
Village groups looked broadly similar, while outdoor rats carried more variety and mixed more freely. Overall separation between groups stayed low, meaning rats move widely and can quickly refill areas after culling. Killing rats alone is thus unlikely to hold, the authors argue. Pairing flea control inside homes with steps that cut contact between people and rats fits the biology better.
