Peculiarities of Management of Sanitary and Anti-Epidemic (Preventive) Measures during Preparation and Holding the 28th Winter Student Games, 2017 in Almaty

Objective was to ensure health and sanitary-epidemiological welfare of the population during XXXVIII World Winter Universiade in the territory of Almaty, within the period of January 30 – February 8, 2017. Materials and methods. Analyzed have been the results of measures, conducted by the specialists of M. Aikimbaev Kazakh Scientific Center of Quarantine and Zoonotic Infections (KSCQZI), in particular the rapid response team, during winter Universiade, 2017. Results and discussion. Due to preventive actions on the provision of sanitary-epidemiological welfare during the preparation and holding of the World Universiade, all the set tasks were accomplished, normative-methodological framework of KSCQZI – amended. Staffing of the rapid response team by the trained specialists and procuring with laboratory equipment facilitated avoidance of emergence and spread of infectious diseases among the guests and residents of Almaty city

Characterization of tularemia foci in the Republic of Kazakhstan from 2000 to 2020

The wide distribution of tularemia in the territory of Kazakhstan is associated with landscape and geographical characteristics. This is explained by a combination of natural factors: the presence of certain types of rodents—reservoirs and sources, ectoparasites—carriers of the causative agent of tularemia. The study of the current spatial and temporal characterization of tularemia in Kazakhstan from 2000 to 2020 will determine the epidemiological status of tularemia and improve the monitoring system in Kazakhstan. In this work we demonstrated the results of a retrospective survey of natural foci of tularemia: analysis of vector, small mammal and human data. The spatial and temporal characteristics of tularemia from 2000 to 2020 in the territory of Kazakhstan were studied in comparison with historical data, including the description of tularemia outbreaks, the clinical picture, and the source of infection, transmission factors, and geographical coordinates of outbreak registration. Sampling was carried out by trapping rodents on snap traps and collecting ticks by rodent combing and by "flagging" methods. For the last 20 years, 85 human cases of tularemia have been reported. During the period from 2000 to 2020, more than 600 strains of F. tularensis were isolated from field rodents and ticks in the natural foci of tularemia. MLVA typing of F. tularensis strains isolated from natural foci of tularemia in Kazakhstan over the past 20 years. The results of retrospective monitoring indicate that currently active foci of tularemia include the Aktobe, West Kazakhstan, Almaty, East Kazakhstan, and Pavlodar regions. Low-activity natural foci are located in the territory of the Akmola, Karaganda, North Kazakhstan, Kostanay, Atyrau, Zhambyl, and Kyzylorda regions. There are no active natural foci of tularemia in the Mangystau and Turkestan regions. The widespread occurrence of tularemia in the country is associated with landscape and geographical features that contribute to the circulation of the pathogen in the natural focus. An analysis of natural foci of tularemia showed that it is necessary to continue monitoring studies of carriers and vectors for the presence of the causative agent of the F. tularensis, in order to prevent mass cases of human disease

Genotypic properties of collection plague microbes strains from the natural plague foci of Kazakhstan

Background. Epidemiological and epizootological monitoring of natural plague foci requires an integrated approach to solving problems, taking into account the phenotypic and genetic variability of Y. pestis and zoning of natural plague foci. The introduction of a new molecular genetic methodology aimed at studying the genomic polymorphism of the plague pathogen provides reliable results for the differentiation of not only groups, but also individual strains.The aim. To determine the genotypes of the plague microbe from different autonomous foci of the Republic of Kazakhstan.Materials and methods. 105 strains of Y. pestis isolated from various natural plague foci of Kazakhstan in 1951–2015 were studied. The phenotypic properties of the strains were studied using standard microbiological methods. A polymerase chain reaction (PCR) was used to detect fragments of the cafl, pst and YPO2088 genes. Multilocus variable number tandem repeat (VNTR) analysis (MLVA) was performed for 25 VNTR loci.Results. The phenotypic properties of the strains were preliminarily studied and the strains of the plague microbe were tested for specificity using the Pest-Quest test system (Kazakhstan). The PCR study confirmed the species-specific affiliation of Y. pestis strains. A variety of strains with typical phenotypic characteristics was revealed. MLVA for 25 key loci (MLVA25) revealed that the studied strains of the plague microbe are phylogenetically closest to the Mediaevalis biovar representatives. A phylogenetic tree of the studied strains has been obtained. It was found that 9 genotypes circulate on the territory of Kazakhstan, and their distribution in certain natural plague foci was determined.Conclusions. The resulting clustering indicates the relationship between the strain groups obtained on the dendrogram by the MLVA25 method and the territories of certain natural plague foci
