摘要:
The health risks for both domestic animals and humans caused by large herbivores in self‐sustaining ecosystems are largely unknown. The aim of this article is to make an inventory of these risks, to explore ways to manage them in practice, and to make recommendations for the quantification of risks. Potential hazards from herbivores in and around Europe are listed using the data of the OIE (Office International des Epizooties). The desired health status and the implementation of control or surveillance measures are important factors when assessing the risks. Results indicate that a regular yearly system of health monitoring of herbivores is necessary. To get more insight into the importance of certain risks (Infectious Bovine Rhinotracheitis, biodegradation of carrion in the field) epidemiological investigations have to be carried out to assess the risk of transmission in different situations (with or without intervention).

摘要:
The defence against infection in high‐yielding dairy cows is correlated with the number and function of circulating neutrophils and depends on their production in bone marrow. Therefore, the DNA content of isolated bone marrow cell suspensions from 7 calves, 7 cows and 14 humans was assayed by flow cytometry. Bovine sternal bone marrow samples were collected within 30 min of death, and human marrow samples were collected by sternal puncture and aspiration. Mononucleated cells were isolated by gradient centrifugation. In the bone marrow samples from calves and cows, 35 ± 2.6% and 31.8 ± 1.5% of the isolated bone marrow cells respectively were in the S/G2/M‐phase. The difference between calves and cows was not significant. In the human samples, only 12 ± 0.8% of the cells were in the SIG2/Mphase. A significant (P < 0.001) difference was observed between the two species. These results indicated that the proliferative, in activity of haematopoietic cells is significantly higher in cattle than in humans.
