Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Objective: This article analyzes the efficiency of live vaccines obtained from the strains of Brucella abortus 82 and 75/79-AV and RB-51 in some regions of Kazakhstan in 2012-2014 and recommends optimal scheme of their use. Methods: There were analyzed the effectiveness of the use of live vaccines (manufactured in Russia) obtained from strains of B. abortus 19, 82 and 75/79-AV in combination with post-vaccination diagnostics of brucellosis in cattle in the farmsteads owned by Vostok-moloko Corporation in Eastern Kazakhstan in the period of 2012-2015. Results: The results of these tests prove that studies of animals 1 month after the vaccination have helped to further identify the animals with hidden form of brucellosis provoked by R-vaccine, which explains the favorable outcome of the research. Conclusion: The above-described scheme of anti-brucellosis activities ensures effective control of the epizootic process of brucellosis by establishing “permanent” (continuous) immunity and permanent control of epizooty in brucellosis threatened/unsafe herds.
