RESUMO
We describe the coding-complete genome sequence of a strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) obtained from a patient with symptoms of coronavirus disease 2019 (COVID-19), detected in the Republic of Kazakhstan. According to the Pangolin COVID-19 database, the studied strain, SARS-CoV-2/Human/KAZ/Delta-020/2021, belongs to lineage AY.122 and consists of 29,840 nucleotides.
RESUMO
This article describes the results of sequencing and analysis of the entire genome of the SARS-CoV-2 virus sampled in Kazakhstan in 2021. The whole-genome sequence of the strain was 29,751 bp. According to the results of phylogenetic analysis (according to the Pangolin COVID-19 database), the SARS-CoV-2/human/KAZ/B1.1/2021 strain studied here was assigned to variant B.1.1.
RESUMO
This research describes the genome sequence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) obtained from a patient with symptoms of coronavirus disease 2019 (COVID-19) who was infected in the Republic of Kazakhstan. Strain SARS-CoV-2/human/KAZ/Britain/2021 consists of 29,815 nucleotides and belongs to lineage B.1.1.7, according to the Pangolin COVID-19 database.
RESUMO
Here, we reported the complete coding sequence of the influenza A/equine/Otar/3/2007 (H3N8) equine virus, first isolated in Kazakhstan in 2007. The hemagglutinin (HA) sequences of the Kazakhstan isolates appeared to be closely related to viruses isolated in early 2000 in Asia. Phylogenetic analysis characterized the Kazakhstan isolates as a member of the Florida sublineage clade 2 by the HA protein sequence.
RESUMO
Currently, although the prevalence of brucellosis in Kazakhstan remains high, there are limited data available on the genetic diversity of circulating Brucella strains. Here, MLVA was employed to genotype a panel of 102 Brucella isolates collected from eight Kazakh regions and neighboring countries (Russia, Kyrgyzstan) during the period 1935-2017. MLVA-11 analysis classified 64 B. abortus strains into genotypes 72, 82, 331, 71, 341 and 69, while one genotype was novel, having no correspondence within the MLVA international database. MLVA-11 analysis of 37 B. melitensis strains showed 100% identity with genotypes 116, 114 and 11. One B. suis strain was classified into genotype 33. Phylogeography based on MLVA-15 demonstrated that all B. abortus and B. melitensis strains belonged to "Abortus C" and "East Mediterranean" lineages, respectively. B. abortus strains from Kazakhstan and Russia resulted genetically related to Portuguese, Brazilian and US isolates, suggesting ancient spread of these lineages from Europe westwards to South America and eastwards to Turkey, Russia and Asia. Most of Kazakh B. melitensis isolates were related to strains circulating in China, likely due to long-term trading partnerships between the two countries. In fine-scale MLVA-15 analysis, 17 B. abortus and 12 B. melitensis genotypes were identified; among them 12 are novel. Interestingly, epidemiological information supporting molecular data were retrieved for two clusters within the B. abortus group, thus proving that MLVA is an appropriate tool for effective traceback analyses. Our findings suggest that molecular genotyping should be applied systematically to support control plans for eradication of brucellosis in Kazakhstan.
