Spatial and temporal characterisation of genetic and phenotypic properties of Yersinia pestis in Kazakhstan's natural plague foci.
Article in Environmental analysis, health and toxicology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The study aimed to analyse data from epizootological monitoring, microbiological and molecular genetic studies to assess the genetic biodiversity of Yersinia pestis (Y. pestis) strains, to determine the effectiveness of using individual methods and to develop the necessary algorithm for evaluating genetic methods and creating a biorepository of natural isolates of these pathogens. As a result, the biodiversity of Y. pestis strains isolated in natural plague foci of Kazakhstan was analysed using classical and modern methods (polymerase chain reaction, Multi Locus Variable Number Tandem Repeat Analysis, VITEK 2 Compact, MiniION Oxford Nanopore, MiSeq sequencer) of research and geographic information system (GIS) technology. Spatial and temporal characteristics of plague infection in the plague-enriched areas of the country were described. The study summarised the characteristics of phenotypic and molecular genetic properties of 1220 Y. pestis strains isolated from different sites in natural plague foci of the country during the period 2010-2023. As a result, 94.8% of Y. pestis strains were typical of these plague foci, and 5.2% of strains had altered properties in some respects. To obtain information on genetic diversity and their geographical distribution, 82 DNA samples of Y. pestis strains were studied. Three phylogenetic trees were constructed, GIS maps were compiled and a gene bank, a biorepository of molecular characteristics was created to obtain specific genetic characteristics of strains and a complete picture of the genetic parameters of the plague pathogen isolated from various sites in natural foci of Kazakhstan.
