Sixty seven samples of blood serum and 43 samples of pathological material from wild boars, dead or shot for diagnostic purpose during autumn-winter hunting 2002-2005 seasons in the Belgorod, Vladimir, Moscow and Tver regions, in the Khabarovsk Krai and Kharkov region of the Ukraine were studied. Virus- and microbe-carriage was detected: Aujeszky"s disease virus, porcine parvovirus, porcine circovirus type 2, lymphotropic herpesvirus-1, porcine cytomegalovirus, Mycoplasma hyopneumoniae, Pasteurella multocida and Salmonella enterica subspecies enterica. In the samples from 10 boars (35% of samples) from the Tver and Moscow regions the classical swine fever virus (CSF) genome was detected by using PCR. The sequencing of E_2 gene 5`-terminal region of CSF virus found, that they were closely related to two field virus isolates recovered earlier from domestic pigs in the Moscow and Vladimir regions proving the existence of epizootic association between the CSF outbreaks among boars and domestic pigs in these regions and the capability of the virus to get over easily the barriers existing between the populations of these animals. Tests of blood serum and pathomaterial from boars for antibodies to viruses of swine reproductive and respiratory syndrome, transmissible gastroenteritis, porcine influenza, enteroviruses and actinobacillosis-induced pleuropneumonia were negative. An undertaken epizootological monitoring showed that boars could be a reservoir of the causal agents and transmitters of infectious diseases.
