[Epidemiological studies of the infection of ticks with borreliosis agents in small mammals from north Germany].

In a two years study into the infestation of ticks with Borrelia burgdorferi from mice in North Germany 1330 mice out of 11 species could be examined. Altogether 508 mice showed to be parasitized by 1445 ticks belonging to three species of Ixodes. 777 I. ricinus from 334 mice could be tested for B. burgdorferi. In 66 ticks (8.5%) from 34 mice (10.2%) borreliae could be demonstrated. These discoveries came from 9 of 14 investigated forest regions in Lower Saxony.

[Ixodes ricinus bites].

Ticks (Ixodes ricinus) are found all over the world, with special preference of a few epidemic areas. They do not only invade their hosts one by one, but often in large groups.

Transmission of Trypanosoma theileri to cattle by Tabanidae.

Tabanids were collected in an area in northern Germany, where pastured cattle were abundant. Trypanosomatidae were identified in 14% of tabanids examined. Twelve cattle became infected with Trypanosoma theileri after applying usually 2-5 infected tabanids, to the intact oral mucosa. Haematopota pluvialis, Haematopota italica, Hybomitra micans and Tabanus bromius were identified as vectors. Infective stages of Trypanosoma theileri were identified in the gut and in the faeces of tabanids by transmission experiments. The minimum prepatent period was less than 4 days. No apparent signs of disease were observed in the infected cattle.

Transmission of Megatrypanum trypanosomes to Cervus dama by Tabanidae.

Four fallow deer, Cervus dama, became infected with Trypanosoma (megatrypanum) sp. by oral application of triturated guts from tabanids collected in an area with deer but without any cattle; four control calves remained negative. Upon challenge with triturated guts from tabanids from an area with pastured cattle, the four calves became infected with Trypanosoma (M.) theileri. The prepatent period in deer was five days or less. Haematopota spp. and Tabanus spp. were identified as vectors of the deer trypanosomes. It is concluded that the trypanosomes of C. dama belong to a Megatrypanum species that is not identical with T. theileri.
