MLSTar: automatic multilocus sequence typing of bacterial genomes in R

PeerJ, 2018
Multilocus sequence typing (MLST) is a standard tool in population genetics and bacterial epidemiology that assesses the genetic variation present in a reduced number of housekeeping genes (typically seven) along the genome.

Microhaplotype Methods Enable Relationship Inference in a Bottlenecked Mammalian Species

Animal Conservation, EarlyView.
Northern elephant seals (Mirounga angustirostris) are among the most genetically depauperate mammals in the world. A near‐total population bottleneck in the 19th century, coupled with the breeding system of extreme polygyny, has challenged efforts to estimate individual reproductive success with genetic methods.

Defining and Evaluating a Core Genome Multilocus Sequence Typing Scheme for Whole-Genome Sequence-Based Typing of Klebsiella pneumoniae

Frontiers in Microbiology, 2017
At present, the most used methods for Klebsiella pneumoniae subtyping are multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE). However, the discriminatory power of MLST could not meet the need for distinguishing outbreak and non-

Repeat Intraocular Sampling and Microbiological Testing in Infectious Endophthalmitis: A 27‐Year Prospective Observational Study at an Australian Statewide Tertiary Referral Centre

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Endophthalmitis requiring multiple ocular tissue sampling for microbiological testing is uncommon and has not been previously studied. This study aims to analyse cases with at least two ocular tissue samplings and testing of different ocular samples against culture yields. Methods A 27‐year prospective observational study using data

Occurrence and genotyping of Giardia duodenalis and Cryptosporidium in pre-weaned dairy calves in central Sichuan province, China

Parasite, 2018
Giardia duodenalis and Cryptosporidium spp. are common human and animal pathogens. They have increasingly been reported in dairy calves in recent years; however, multilocus genotyping information for G. duodenalis and Cryptosporidium infecting pre-weaned

Genetic diversity of Helicobacter pylori isolates from patients with gastric diseases in Isfahan

Advanced Biomedical Research, 2022
Background: Helicobacter pylori (H. pylori), a spiral-shaped bacterium colonizing the human stomach, is generally acquired in childhood. This pathogen is highly diverse and can be used as genetic markers for predict the history of human migrations.

Genetic and environmental factors associated with survival of a rare songbird in a fragmented urban landscape

Conservation Science and Practice, EarlyView.
We conducted individual banding and resighting studies and collected genetic data in populations of coastal Cactus Wrens in Orange and San Diego Counties between 2009 and 2020. We found that survival was much lower for hatch year birds than after hatch year birds and that higher precipitation and heterozygosity had positive effects on survival. Results

Unique Clindamycin-Resistant Clostridioides difficile Strain Related to Fluoroquinolone-Resistant Epidemic BI/RT027 Strain

Emerging Infectious Diseases, 2020
During a surveillance study of patients in a long-term care facility and the affiliated acute care hospital in the United States, we identified a Clostridioides difficile strain related to the epidemic PCR ribotype (RT) 027 strain associated with ...

Human Campylobacteriosis in Luxembourg, 2010–2013: A Case-Control Study Combined with Multilocus Sequence Typing for Source Attribution and Risk Factor Analysis

Scientific Reports, 2016
Campylobacteriosis has increased markedly in Luxembourg during recent years. We sought to determine which Campylobacter genotypes infect humans, where they may originate from and how they may infect humans.
