NATIONAL VETERINARY
RESEARCH INSTITUTE
established in 1945
as a scientific institution of the
Ministry of Agriculture
The major mission of the NVRI
is applied research in veterinary
medicine and provide services for
the public veterinary sector

Research staff
The Institute employs 350 persons
‰ 33 researchers with Sc.D. and Ph.D.
‰ 40 researchers with Ph.D
‰ 49 researchers with D.V.M. or M.Sc
‰ 102 technicians
Organization of the NVRI
‰ Laboratories representing basic disciplines
(bacteriology, virology, biochemistry, parasitology,
pathology,toxicology and pharmacology, food and
feedingstuffs hygiene
‰
Laboratories for the diseases of particular animal
species: equine, swine, poultry, fish
‰
Laboratories for diseases of special significance for
animals and husbandry (tuberculosis, foot and mounth
disease, mastitis) and zoonoses
The NVRI contributes the activity on
the following fields:
‰ Experimental research into animal diseases
‰ Reference activity dedicated to the regional
diagnostic laboratories and the Veterinary Inspection
‰ Active surveillance - implementation and execution of
the Multiannual Monitoring Programme
17.01.2005
Construction of the new
laboratories started
National reference laboratories (NRL)
A network of 14 laboratories within different
departments of NVRI appointed with the Act of
Ministry of Agriculture and Rural Development
of October 21, 2004
for the reference activities
The most important elements in the
functioning of the NRL are:
‰ Reference duties are fully integrated with
activity of NVRI departments undertaking
research and training
‰ Reference activity has its own budget
Activities of NRL (46)

What are the duties of NRL?
‰ to collaborate with the regional laboratories in terms of
harmonization standards and diagnostic methods
‰ to carry out the proficiency tests
‰ to control the quality of diagnostic reagents used for the
tests reffered to the diagnosis of infectious diseases
‰ to collect and process epidemiological data related to animal
infectious diseases and official food control
‰ to perform laboratory examinations to confirm the results
done by authorized laboratories, if there are some doubts
‰ to train the employees of the authorised laboratories
NRL for Campylobacter
Located at Department of Hygiene of
Food of Animal Origin of NVRI
Campylobacter – main
activities (since 2004)
‰ Development of molecular identification
methods (PCR)
‰ Application of PCR and RFLP methods for
differentiation of the strains
‰ Isolation and identification of Campylobacter
from poultry
