Multilocus sequence types of invasive Corynebacterium diphtheriae isolated in the Rio de Janeiro urban area, Brazil [PDF]

, 2012
Invasive infections caused by Corynebacterium diphtheriae in vaccinated and non-vaccinated individuals have been reported increasingly. In this study we used multilocus sequence typing (MLST) to study genetic relationships between six invasive strains of

Genomic Insights Into Carbapenem‐Resistant Klebsiella pneumoniae in Pediatric Bloodstream Infections in Zhejiang, China (2019–2024)

Journal of Clinical Laboratory Analysis, EarlyView.
The primary mechanism of carbapenem resistance identified in pediatric CRKP‐BSI strains was the production of Class B metalloenzymes. We report, for the first time, an outbreak of bloodstream infections in a neonatal ward caused by the dissemination of NDM‐1‐producing ST25 K. pneumoniae.

Evolutionary history of Leishmania killicki (synonymous Leishmania tropica) and taxonomic implications [PDF]

, 2015
Background: Leishmania (L.) killicki is responsible for the chronic cutaneous leishmaniasis. The taxonomic status of this parasite is still not well defined. It was suggested on one hand to include this taxon within L.

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India

Nordic Journal of Botany, EarlyView.
A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)

Fecal non-aureus Staphylococci are a potential cause of bovine intramammary infection [PDF]

, 2020
The presence of non-aureus staphylococci (NAS) in bovine rectal feces has recently been described. Similar to other mastitis causing pathogens, shedding of NAS in the environment could result in intramammary infection.

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Multilocus Sequence Typing System for Group B Streptococcus [PDF]

Journal of Clinical Microbiology, 2003
ABSTRACT A multilocus sequence typing (MLST) system was developed for group B streptococcus (GBS). The system was used to characterize a collection ( n = 152) of globally and ecologically diverse human strains of GBS that included representatives of capsular serotypes Ia, Ib, II, III, V, VI, and VIII ...

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

A Population-Based Surveillance Study of Shared Genotypes of Escherichia coli Isolates from Retail Meat and Suspected Cases of Urinary Tract Infections. [PDF]

, 2018
There is increasing evidence that retail food may serve as a source of Escherichia coli that causes community-acquired urinary tract infections, but the impact of this source in a community is not known. We conducted a prospective, population-based study
