The paper presents the epidemiological situation regarding Aujeszky’s disease in pigs from the Wielkopolska region, starting from the first recorded cases of the disease in the 1950s. Serological studies carried out in the 1960s and 1970s detected seroreagents at the level of 11.1% and 12.8% respectively, while the results obtained in the years from 2001 to 2005 showed an infection of 9.2% of pigs that came from 15.6% of the tested herds. The occurrence of Aujeszky’s disease in pigs for over 60 years in the Wielkopolska region was the cause of the unfavorable epidemiological situation and economic problems in this area. The implementation of an eradication program for Aujeszky’s disease in pigs in of the Wielkopolska voivodeship started in May 2008, and in the first year 9.25% herds were discovered as infected, based on the positive results of serological testing. The level of infection in the following years of the program (2009-2013) revealed a rapid decreasing tendency to the levels of: 6.55%, 2.5%, 0.26%, 0.03% and 0.007%, respectively, in each year. In the period from 2008 to 2013, within the scope of the program in the Wielkopolska voivodeship, 2 578 652 serological tests were performed, and the eradication was based either on the principle of “vaccination–eradication”, or the slaughter of all animals in infected herds with a small herd size. During the implementation of the eradication program for Aujeszky’s disease, 1 709 204 pigs were vaccinated with the usage of deleted vaccine, and 119 537 were slaughtered. Since the beginning of 2014 extensive monitoring studies have been carried out, and on 5 August 2014, all 34 counties of the Wielkopolska voivodeship have been declared as free of Aujeszky’s disease. Maintaining this status in the forthcoming years will allow the recognition of the entire Polish territory officially free of Aujeszky’s disease virus in pigs.

The publication presents the results of monitoring Q fever in the Wielkopolska Voivodeship and three outbreaks disclosed as part of a clinical field practice. In five years (2011–2015) of examination in the Wielkopolska Voivodeship, 2,431 serological tests were carried out (1,851 in sheep, 343 in goats and 237 in cattle). Antibodies against Coxiella burneti were found three times. The first positive result in 2011 affected herds of goats and cattle and was confirmed in the reference laboratory of the National Veterinary Research Institute in Pulawy. A specific DNA sequence for Coxiella burneti by real-time PCR method was found. The farm consisted of 1,494 goats and 397 cattle. Serological tests were carried out to give positive results in 15.3% of the cattle and 5.77% of the goats from the whole herd. Breeding selection and the elimination of seropositive animals and double oxytetracycline treatment reduced the proportion of animals with a positive result to 5.53% in cattle and 0.96% in goats. After more than a year the elimination of seropositive animals and probable natural decline in antibody levels has led to the recognition of an outbreak of Q fever to be eliminated. The second positive result of the monitoring of Q fever was found in 2014 in one cow out of seven respondents, but the serological test was not confirmed in the reference, as a specific DNA sequence for Coxiella burneti was not found. The research conducted in sheep in 2015 showed the presence of antibodies against Coxiella burneti in two samples. The results were confirmed by the detection of genetic material of the pathogen by real-time PCR examination in the National Veterinary Research Institute in Pulawy. Three outbreaks of Q fever revealed in clinical practice related to bovine herds where clinical disturbances were observed in: reproduction, milk production decrease or increase in internal body temperature and symptoms of the respiratory system. The positive ELISA test results were the reason for the elimination of seropositive animals. Moreover, after the disclosure of infection two herds were vaccinated using an inactivated vaccine Coxevac (CEVA), which caused the improvement of production results and relief of clinical symptoms. It is worth mentioning that in two farms along with cattle there were fallow deer supported by staff cowman. Official monitoring tests of Q fever revealed an outbreak of the disease in a herd of goats and cattle, which lead to taking effective action to protect public health because of the zoonotic nature of this infection and epidemiological risk. In the disclosure of these clinical signs in cattle it is advisable to carry out laboratory tests for Q fever.
