Natural foci of plague in Kazakhstan in the space-time continuum
Comp Immunol Microbiol Infect Dis. 2023 Jul 15;100:102025. doi: 10.1016/j.cimid.2023.102025. Online ahead of print.ABSTRACTThe relevance of the problem of the stated topic lies in the fact that the causative agent of the plague infection demonstrates high survival while maintaining high virulence in the territories, which are enzootic in terms of the plague. The study aimed to investigate the geographic distribution and genetic diversity of the plague pathogen in endemic regions through molecular genetic research. The work included the results of laboratory studies of 3058 samples, including soil - 1154, burrow substrates ...

Temporal changes in antibiotic resistance and population structure of methicillin-resistant Staphylococcus pseudintermedius between 2010 and 2021 in the United States
Comp Immunol Microbiol Infect Dis. 2023 Jul 24;100:102028. doi: 10.1016/j.cimid.2023.102028. Online ahead of print.ABSTRACTThe aim of this study was to perform a phenotypic and molecular epidemiological survey to determine temporal changes in the antimicrobial resistance and population structure of methicillin-resistant Staphylococcus pseudintermedius (MRSP) in the United States. Samples from 200 S. pseudintermedius isolates were obtained from veterinary diagnostic facilities located in geographic regions sampled approximately ten years ago and compared to samples obtained in 2021. Kirby-Bauer disk diffusion was used to de...

Whole genome sequencing of Bacillus anthracis isolated from animal in the 1960s, Brazil, belonging to the South America subclade
Comp Immunol Microbiol Infect Dis. 2023 Jul 25;100:102027. doi: 10.1016/j.cimid.2023.102027. Online ahead of print.ABSTRACTBacillus anthracis causes anthrax disease and can affect humans and other animals. This zoonotic disease has an impact on the economic and health aspects. B. anthracis population is divided into three major clades: A (with worldwide distribution), B, and C (restricted to specific regions). Anthrax is most common in agricultural regions of central and southwestern Asia, sub-Saharan Africa, Southern and Eastern Europe, the Caribbean, and Central and South America. Here, we sequenced by short and long rea...

Non-adaptive evolution in codon usage of human-origin monkeypox virus
This study also found that the mutations of Mpox led to changes in non-adaptative genes in different organs. Additionally, we found that codon usage of Mpox was less similar to that of up-regulated host genes and more similar to that of down-regulated host genes post-infection, indicating that codon usage affects host gene expression. Overall, the study highlights the non-adaptive changes in codon usage as a potential cause of differences in Mpox virulence and provides insights into the evolutionary and adaptive mechanisms of Mpox and its potential impact on pathogenicity and host adaptation.PMID:37487313 | DOI:10.1016/j.c...

More insights about genomic population structure of Mycobacterium avium subspecies paratuberculosis (Map) from multiple hosts in west and central provinces of Iran using a boosted genotyping approach
Comp Immunol Microbiol Infect Dis. 2022 Nov 12;100:101912. doi: 10.1016/j.cimid.2022.101912. Online ahead of print.ABSTRACTTo investigate the population genetic of Mycobacterium avium subsp. paratuberculosis (Map) in Iran, Mycobacterial Interspersed Repetitive Units (MIRUs) and Multi Locus Short Sequence Repeat (MLSSR) system were employed. Numerous genotypes by MIRU (N = 11) and MLSSR (N = 9) methods bearing discriminatory indices of 0.90 and 0.79 respectively, were obtained. Browsing the INRA-Nouzilly list (http://mac-inmv.tours.inra.fr/) detected 3 of the found patterns as new types. Some loci either MIRU-VNTR or SSR pr...
