Inactivated vaccine against Aujeszky's disease.

Background And Aim: The Aujeszky's disease, also known as Pseudorabies, remains one of the most problematic fulminant diseases in domestic animals, affecting the central nervous system. The study aimed to investigate the effect of an inactivated vaccine against Aujeszky's disease based on "Kordai" virus strain.

Materials And Methods: To test the inactivation of the "Kordai" strain (grown by the roller method in VNK-21/13 cell culture with an infectious titer of at least 7.

Impact of geographical factors on the spread of animal brucellosis in the Republic of Kazakhstan.

In Latin and Central America and in most Asian countries, brucellosis remains an insufficiently studied disease. This study aims to determine the national and regional incidence of brucellosis among cattle (cows) and small ruminants (sheep, goats) in the Republic of Kazakhstan, as well as to identify the effect of climatic and geographical factors on the incidence rates. Thematic maps were created in an open geographic information system QGIS version 2.

Phenotypic and genotypic characteristics of Brucella isolates from the Republic of Kazakhstan.

The purposes of this study were to determine phenotypic and genotypic characteristics of Brucella isolates from the Republic of Kazakhstan and to determine their biotype. The focus was laid on culture-morphological, biochemical, and biological properties of 59 Brucella isolates from primary cultures. Material was isolated from blood and tissue of serum-positive killed, dead diseased, or aborted domestic cattle from different regions of Kazakhstan where brucellosis is a common problem.
