Abstract

Apparent (with respiratory symptoms, conjunctivitis, abortion, alterations of the external genitals and nervous symptoms), as well as inapparent disease forms of IBR/IPV with virus carrier state have been reported and analyzed. Approx. 20 to 25 years ago the infection was low in the Hungarian cattle population. High incidence of the infection at present was thought to the significant cattle import from North-America, the relatively large size of the stocks, neglect of the importance of infection and the lack of the control of animal movement from that respect. Economic importance of direct and indirect losses has been pointed out. Most important and final goal of the control is the eradication, that started in Hungary during the second half of 1980's. Since the economical difficulties in 1990, as well as the unfavourable economical and public-health position of cattle breeding have slowed down the sporadic trials. Of the eradication methods, the safe but very expensive method of "depopulation and repopulation with a free stock" can not be carried out. Owing to the low contagiosity of the virus, the most useful methods are the "classical" selection with purposeful separation, as well as the "repopulation of old stock with a new generation" because of the Hungarian system of calf rearing and growing cattle management that results in a low infection rate in growing cattle. The "modern" selection eradication method under the umbrella of marker vaccination has not been yet a practice in Hungary, the biotechnological method however can only be proposed in case of animals with an extremely high breeding value. In the selection of methods to be followed, representative serological survey of aborted, recently calved cows, 3 to 6 months old calves and pregnant heifers can be of decisive importance, Results of serological surveys in case of non-vaccinated (eradication by selection) or vaccinated stocks (repopulation of old stock with a new generation), ensuring the personal and technical conditions, as well as the application of specific and/or non-specific control may lead to the eradication. In case of a successful eradication, organization of systematic control is an essential condition of to maintain the free state.
