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.

Core Genome Multilocus Sequence Typing and Single Nucleotide Polymorphism Analysis in the Epidemiology of Brucella melitensis Infections

Journal of Clinical Microbiology, 2018
The use of whole-genome sequencing (WGS) using next-generation sequencing (NGS) technology has become a widely accepted method for microbiology laboratories in the application of molecular typing for outbreak tracing and genomic epidemiology.

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

Evaluation of Multilocus Sequence Typing of Cyclospora cayetanensis based on microsatellite markers

Parasite, 2019
Cyclospora cayetanensis is a human parasite transmitted via ingestion of contaminated food or water. Cases of C. cayetanensis infection acquired in the United States often go unexplained, partly because of the difficulties associated with epidemiologic ...

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 critical re-evaluation of multilocus sequence typing (MLST) efforts in Wolbachia

bioRxiv, 2017
Wolbachia (Alphaproteobacteria, Rickettsiales) is the most common, and arguably one of the most important inherited symbionts. Molecular differentiation of Wolbachia strains is routinely performed with a set of five multilocus sequence typing (MLST ...

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 ...

Phylogeny, species delimitation and machine learning bridge the gap between DNA sequences and morphology in the lichen genus Arctomia (Arctomiaceae, Ascomycota)

TAXON, EarlyView.
Abstract This study investigates species boundaries in the lichen genus Arctomia (Arctomiaceae, Ascomycota) using an integrative approach combining molecular phylogenetics, full Bayesian population delimitation, heuristic and model‐based species delimitation, and supervised machine learning applied to morphological data.

Extended-spectrum beta-lactamases-producing Escherichia coli in common vampire bats Desmodus rotundus and livestock in Peru [PDF]

, 2018
Antibiotic resistance mediated by bacterial production of extended‐spectrum beta‐lactamase (ESBL) is a global threat to public health. ESBL resistance is most commonly hospital‐acquired; however, infections acquired outside of hospital settings have ...
