The paper presents data on studied properties of lumpy skin disease virus adapted to goat gonad and lamb testicle cell cultures. Experimental infection of cattle with the obtained strain of lumpy skin disease virus induces systemic infection.

Results of the international interlaboratory proficiency tests on FMD diagnosis carried out by the FGBI ARRIAH Reference Laboratory for FMD Diagnosis in 2013-2015 were analyzed. Ten laboratories from seven CIS-countries took part in the proficiency tests, including the Republic of Kazakhstan, the Republic of Armenia, the Republic of Moldova, the Republic of Belarus, the Republic of Azerbaijan, the Republic of Tajikistan, the Kyrgyz Republic and five laboratories of the FGBI «ARRIAH».

Contagious bovine pleuropneumonia (CBPP) is a highly contagious transboundary disease of ruminants which is currently widely spread on the African continent. Morbidity rate in a susceptible herd reaches 100% and mortality rate varies from 10% to 90% depending on the breed, individual susceptibility and animal resistance. Today, there is a huge risk of the agent introduction with animals and raw material exported from affected endemic areas of Africa to the areas free from contagious bovine pleuropneumonia (including Eurasia).

The paper demonstrates dependence of virus-neutralizing antibody production and emulsion FMD vaccine immunogenicity on administration of vaccines against different infectious porcine diseases. Optimum interval between the administrations of the emulsion FMD vaccine and vaccines against other porcine diseases was determined.

The paper covers comparative assessment of clinical and postmortem signs in wild boars and domestic pigs infected with one and the same epizootic isolate of African swine fever virus. In addition, a model has been developed to demonstrate the disease spread under conditions comparable to those on a pig farm. Based on the obtained results two infectious doses 50 and 5000 H AU/head were chosen for infecting the animals with «Shikhobalovo 10/13» isolate of African swine fever virus. When infecting the animals with the abovementioned isolates both wild boars and domestic pigs demonstrated similar clinical and postmortem signs typical for acute form of African swine fever.

Progress trends in classical swine fever (CSF) epidemic situation in the Russian Federation in 1996-2015 are discussed in the paper. Spatial shift of CSF outbreaks from the central regions of the country (2007-2012) to the western and eastern border regions of the Russian Federation (2013-2015) has been confirmed. Based on the analysis, a short-term prognosis for 2016 has been made as well as recommendations on DIVA-based measures for CSF eradication in domestic pigs and wild boars in the RF have been provided.

The paper demonstrates results of the studies of pathogenicity of fowl pox virus (Chicken/Rus-Rjazan/ FPV/2009 isolate) and pigeon pox virus (Pigeon/Rus-Astrakhan/PGPV/2012 and Pigeon/Rus-Vladimir/ PGPV/2010 isolates) using cross-infection. The chicks were infected intraocularly and intranasally or in-tradermally and epidermally. No clinical signs were reported in chicks and pigeons following intraocular and intranasal infection. Epidermal and intradermal infection pigeon pox isolates induced local skin lesions only in pigeons. Proliferative necrotizing folliculitis was reported in chicks only post intradermal infection with fowl pox isolate. Therefore it was experimentally proved that the recovered field isolates of pigeon and fowl pox viruses are highly specific for the natural host.

Pathological material from poultry was subjected to bacteriological tests for infectious rhinitis in chickens. Nine Avibacteruim paragallinarum isolates were recovered from 84 samples, i.e. 10.7%. The agent was recovered from mucosal exudate of nasal cavity and infraorbital sinuses, from conjunctival sac content and lungs. All the isolates were gram-negative short rods or Cocci that needed V-growth factor and sera, did not produce catalase, fermented glucose and sucrose, did not split trehalose and galactose. Taking into account the mentioned signs, it was possible to differentiate Avibacteruim paragallinarum from other apathogenic avian heamophilius bacteria.
