Diseases Transmitted from Rats to Humans
Rats serve as reservoirs for a range of bacterial agents that can infect humans through direct contact, bites, contaminated food, water, or aerosolized particles. Transmission often occurs in urban environments where rodent populations intersect with human activity, leading to sporadic outbreaks and occasional endemic patterns.. Date latest changes:
Raisins contain a modest spectrum of micronutrients that may contribute to a rodent’s diet. The fruit supplies several water‑soluble vitamins and a range of essential minerals, yet the overall nutritional profile is dominated by simple sugars.. Date latest changes:
Dream symbolism where rats are killed
Dreams in which rats are slain often signal adverse emotional states. The act of killing a rodent in a nocturnal vision reflects inner turmoil rather than triumph. Persistent anxiety: the image suggests an unresolved fear that resurfaces nightly.. Date latest changes:
