Effective management of any group of diseases in the population, including rare diseases, needs to know the basic epidemiological parameters. The issue of rare diseases in the concept of state health policy has absented in many countries due to the difficulty of diagnosis, treatment and subsequent care of such patients. There is no conception of collection and processing of data regarding rare diseases, neither is there any unified conception of diagnosis, treatment, and overall health care of patients with rare diseases. The central availability of data concerning rare diseases is very low for different medical specialisations which deal with this issue. There exist only partial pieces of information, which are spread across different workplaces. The SR should participate in European information network on rare diseases. The SR is a member of ICBDSR (http://www.icbdsr.org) but not EUROCAT (http://www.eurocat-network.eu/), which is necessary to be changed!
The National Health Information Centre (NHIC) is a source of rare diseases in the following databases: National register of congenital anomalies, National cancer registry, Registry of patients with diabetes mellitus 1, National register of congenital anomaly of heart. The key to the knowledge of the real state of disease incidence rate in the population is an effective collaboration between relevant partners (including implementation of systematic control mechanisms), which is a basis for success.
During December 2007 and November–April 2008/2009, 128 gastrointestinal tracts and 1680 faecal samples of hares from different parts of the Czech Republic were examined. Evaluation of the faeces samples indicated that the samples could have been infected with any one of the following parasites: Eimeria spp., Trichostrongylus retortaeformis, Trichuris leporis, Graphidium strigosum, Strongyloides sp., Protostrongylus spp. and Anoplocephalidae tape-worms. Trichostrongylus retortaeformis was the most common nematode (75.8 %). 39.8 % of the animals were infected with Trichuris leporis. Only four hares were in-fected with Graphidium strigosum. Eimeria spp. was the most commonly occurring parasite (90.5 %). The follow-ing species were found: Eimeria coquelinae, E. cabareti, E. leporis, E. babatica, E. europea, E. pierrecouderti, E. macrosculpta, E. orbiculata and E. stefanski. Eimeria coquelinae was the most prevalent species (68.4 %). Eimeria cabareti and E. leporis were the next most frequently found species (64.5 % and 57.8 %, respectively).
