Examination of the infectious respiratory diseases of ruminants

Identification of the bacteria and viruses having etiologic role in the respiratory diseases of cattle, sheep and goats, study of the cultural, biochemical, serological and genetic characteristics of bacteria (Mannheimia haemolytica, Pasteurella multocida, Bibersteinia trehalosi, Histophilus somni), examination of pathogenesis, development of diagnosis, therapy, prevention and control.

 

 

Examination of some bacteria of the Family Pasteurellaceae and the diseases caused by them

Examination of the cultural, biochemical, serological and genetic characteristics of some bacteria of the Family Pasteurellaceae (Mannheimia haemolytica, Pasteurella multocida, Bibersteinia trehalosi, Histophilus somni, Actinobacillus pleuropneumoniae, Actinobacillus seminis, Actinobacillus rossii, Pasteurella mairii, Pasteurella aerogenes, Avibacterium paragallinarum) causing diseases in different animal species.

 

 

Characterisation of Actinobacillus pleuropneumoniae strains isolated in Hungarian swine herds

Characterisation of cultural, biochemical features, antigen structure, genome structure, antibiotic resistance and pathogenicity of Actinobacillus pleuropneumoniae strains isolated in Hungary.

 

 

 

Comparative examination of Histophilus somni strains isolated from farm animals

Histophilus somni strains cause respiratory disease and thromboembolic meningoencephalitist in calves and epididymitis and orchitis in sheep, however they can be detected sporadically in cases abortions. The aim of the examinations is comparison of H. somni strains isolated from different animal species and diseases on the basis of metabolic profile and genome structure.

 

Investigation of co-infections with porcine circoviruses

Circovirus infection causes considerable immunosuppression in animals providing opportunities to other pathogens, which do not cause disease or only mild clinical symptoms in circovirus free animals.

Genetic variability of canine and feline parvoviruses

New genetic and antigenic variants of parvoviruses appear in vaccinated animals in relation to a selecting effect caused by regular vaccinations. The aim of this research project is the identification of these variants and possible vaccine candidates.

Evolution of porcine circoviruses

The evolution of circoviruses still has many unanswered questions. The aim of this research project is the investigation of the evolution of porcine circoviruses by recognizing natural host species and identifying a possible common ancestor.

Detection and examination of infections caused by new types of porcine parvoviruses

Besides the one species of porcine parvovirus (PPV1), recognized previously, several new parvoviruses (PPV2, PPV3, PPV4, PPV5, PPV6, PPV7) and related bocaparvoviruses were identified. The aim of this research project is to clarify whether these viruses have a role as pathogens.

Hepatitis E virus in animals

Hepatitis E virus can cause acute hepatitis in humans. The main reservoir of the virus is swine, although seropositivity can also occur in companion animals (mostly dogs and cats). The aim of this study is to clarify the role of these animals in human diseases.

Coronaviruses of swine

Genetic mapping of different coronaviruses appearing in swine herds is important in relation to the high recombination rate characteristic to these viruses. The aim of this study is the characterization of new variants and their possible pathogenic effect.

Effect of pro-and prebiotics in autoimmune diseases

Pro- and prebiotic consumption proved to have a beneficial effect in human autoimmune diseases. The aim of this research project is to examine this effect in similar diseases of dogs.
