Genomic perspective on the bacillus causing paratyphoid B fever.

Paratyphoid B fever (PTB) is caused by an invasive lineage (phylogroup 1, PG1) of Salmonella enterica serotype Paratyphi B (SPB). However, little was known about the global population structure, geographic distribution, and evolution of this pathogen. Here, we report a whole-genome analysis of 568 historical and contemporary SPB PG1 isolates, obtained globally, between 1898 and 2021.

[Laboratory errors for identification of the escherichia coli strains of the serological groups O6 and O25 as acute intestinal infections.].

Were studied the genes encoding the virulence factors of 221 strains: E. coli O:H (194) and E. coli O:H (27), isolated in 2014-2018 from stool samples of children and adults examined according to epidemic indications.

[Antimicrobial resistance and clinical significant resistance mechanisms of Salmonella isolated in 2014-2018 in St.Petersburg, Russia.].

The article presents the results of antimicrobial resistance monitoring of Salmonella isolated from children and adults with diarrhea in St. Petersburg in 2014-2018. In 746 isolates of 42 serovars more than 90,0% belonged to three: S.

[Molecular-genetic characterization of shiga-toxin producing Escherichia coli isolated during a food-borne outbreak in St. Petersburg in 2013].

Unlabelled: Shiga toxin-producing Escherichia coli (STEC) food-borne infections are reported worldwide and represent a serious problem for public healthcare. In the Russian Federation there is little information on epidemiology and etiology of STEC-infections as well as on molecular-genetic peculiarities of STEC pathogens.

Objective: Our aim was to describe a food-borne outbreak as hemorrhagic colitis (HC) along with hemolytic uremic syndrome (HUS), enterocolitis, and acute gastroenteritis in children in St.

[Characteristics of enterohemorrhagic Escherichia coli O145:H28 isolated from a patient with hemolytic-uremic syndrome].

Aim: Determine etiologic significance of clinical strains of E. coli O145:H28 isolated from feces of a patient with hemolytic-uremic syndrome (HUS).
