Campylobacter is the leading cause of human bacterial gastroenteritis worldwide and has a major impact on global public health. Whole Genome Sequencing (WGS) powerful tool applied in study foodborne pathogens. The objective present was to apply WGS determine genetic diversity, virulence factors determinants antimicrobial resistance populations C. jejuni coli Peru. A total 129 strains (108 21 coli) were sequenced using Illumina Miseq platform. In silico MLST analysis identified high diversity...

Objectives. To describe the phenotypic and genotypic patterns of antimicrobial resistance Salmonella Infantis in Peru. Materials Methods. Two hundred ninety-seven strains sp. submitted to National Institute Health (INS, Spanish) during 2014-2016 were analyzed. The phenotypically characterized by microbiological, serological, susceptibility tests. Based on patterns, 46 selected genetically next generation sequencing. Results. 193/297 (65%) identified, which 143 (74.1%) multidrug-resistant...

To describe the frequency of antimicrobial resistance rates and spatial-temporal distribution Shigella species from last 10 years in Peru.A cross-sectional descriptive study was carried out. A total 1668 strains, remitted as part national enteric pathogen surveillance 2011 to 2020, were analysed. The strains confirmed by conventional tests serotyped with polyvalent monovalent antibodies. Also, susceptibility performed according Kirby-Bauer method.The most frequent S. sonnei (49.2%), followed...

Abstract The main strategy for response and control of COVID-19 demands the use rapid, accurate diagnostic tests aimed at first point health care. During emergency, an increase in asymptomatic symptomatic cases results a great demand molecular tests, which is promoting development application rapid technologies. In this study, we describe evaluation RT-LAMP to detect SARS-CoV-2 based on three genes ( ORF1ab , M N genes) monoplex triplex format. assays were compared with gold standard method...

Non-typhoidal Salmonella (NTS) is one of the leading causes foodborne outbreaks worldwide, especially in low- and middle-income countries such as Peru. To understand dynamics NTS serotypes circulating country, whole genomes 1122 strains from 1998 to 2018 were analyzed using phylogenomic comparative genomics tools. A total 40 different Sequences Type (STs) identified, five most frequent being ST-32 (S. Infantis, 37.25%), ST-11 Enteritidis, 23.8%), ST-19 Typhimurium, 14.17%), ST-31 Newport,...
