descent and spreading

the moving rat originally originates from central Asia and north China. It has itself like the house rat as culture follower of humans into all world spread, however only approx. 1000 years later. Bone finds thatMoving rat in Schleswig-Holstein became on 9. to 10. Century dates. Starting from that 18. Century began a strong spreading, which led to the displacement of the house rat. Under the changed way of life of humans, the building of modern houses and drains the moving rat could increase strongly.In less modern settlements of humans their circulation area is limited against it. So it is to be found also today in Africa only in large and ports. It swims very well, does not climb is against it not their strength. Straight one in modern large cities finds it ideal conditions. One estimates,that e.g. in New York 16 million moving rats live, thus two per inhabitant.


the moving rat is a Allesfresser. It takes more animal food to itself than the house rat. It can temporarily nourish itself in addition, of excluding vegetable food, inIt lives colonies of sea-birds again purely carnivor. This one should not take oneself however as manual for nutrition in shank. There one should it very variedly nourish, a good basic fodder is barley.

moving rat

the behavior of the moving rat is very flexible. In the open land she builds for Erdhaufen with courses, which lead to the nest and stores. In a nest several females can at the same time largepull a throw of 6 to 10 young animals.If the nut/mother precipitates, another female animal takes over the breeding care. The young animals have a pronounced play behavior, a female rat can in their life 6 to 8 throws draw up. In the open land a moving rat becomes however hardly older than one year.

The members of a group recognize each other by the group-specific smell. In groups of moving rats can do experiences, the particularGroup members made, to other members to be passed on.

It had a pronounced ability to learn and can be bred in shank easily. This made it a preferential experimental animal. The experimental psychology and behavior biology examine the learning behavior on the basis the moving rat among other things.


the few specialized and thus to very flexible free-living animal are considered generally as food parasits.

the moving rat as disease carriers

with the plague did not play the moving rat in Europe a large role. It becomes of the rat flea Xenopsylla cheopsis also as a landlordassumed, it can work thus as carriers, but at present the large Pestepedemien was hardly common it in Europe. Further free-living moving rats come in addition, as mechanical vectors for the most diverse pathogens into consideration. They are clear as carriers of typhoid fever, Cholera, Ruhr, Tuberkulose, Trichinose, Leptospirose, muzzle and claw epidemic and of thread worms determined [1].

the moving rat as an exciter landlord

free-living moving rats are beside other small rodents likewise reservoir landlords for various Borrelienarten (bacteria), then also from vectors like e.g. Zecken to animal and humans to be transferred can.
