Analysis of Salmonella enterica serovar Enteritidis isolates from South Korea based on whole genome sequences, antibiotic resistance, and virulence assays.

We compared 15 Salmonella Enteritidis isolates collected in South Korea in 2023: 11 from chickens and 4 from humans. All isolates belonged to ST11, and they were divided into two clusters, rST3888 and rST1425. All four human isolates were colistin-resistant, and mcr-1 was identified in three isolates.

Phylogenetic Analysis Based on Whole Genome Sequences, Antibiotic Resistance, and Virulence of Clinical Isolates from South Korea.

is a major cause of foodborne disease and frequently causes human salmonellosis in South Korea. In this study, we investigated the genome diversity, antimicrobial resistance, and virulence of clinical isolates of from South Korea. We collected 42 subsp.

Machine Learning Using Template-Based-Predicted Structure of Haemagglutinin Predicts Pathogenicity of Avian Influenza.

Deep learning presents a promising approach to complex biological classifications, contingent upon the availability of well-curated datasets. This study addresses the challenge of analyzing three-dimensional protein structures by introducing a novel pipeline that utilizes open-source tools to convert protein structures into a format amenable to computational analysis. Applying a two-dimensional convolutional neural network (CNN) to a dataset of 12,143 avian influenza virus genomes from 64 countries, encompassing 119 hemagglutinin (HA) and neuraminidase (NA) types, we achieved significant classification accuracy.

Colistin heteroresistance in Citrobacter freundii clinical isolates from Republic of Korea.

We investigated colistin heteroresistance in Citrobacter freundii isolates from Korean hospitals. Using population analysis profiling (PAP), we detected colistin heteroresistance in 31.3% of isolates.

Roles of crrAB two-component regulatory system in Klebsiella pneumoniae: growth yield, survival in initial colistin treatment stage, and virulence.

Objectives: Alternation of the colistin resistance-regulating two-component regulatory system (crrAB) is a colistin-resistance mechanism in Klebsiella pneumoniae (K. pneumoniae), but its role in bacteria is not fully understood.

Methods: Twelve colistin-susceptible K.

Re-identification and Characterization of Multidrug-Resistant Corynebacterium haemomassiliense-Like Organisms from Humans.

Recently, non-diphtheriae Corynebacterium spp. have been increasingly reported in patients. In addition, several novel species of Corynebacterium isolated from humans.

Prediction of maxillary canine impaction using eruption pathway and angular measurement on panoramic radiographs.

Objectives: To compare the normal eruption pattern and angulation in impacted maxillary canines using panoramic radiographs to predict maxillary canine impaction.

Materials And Methods: Patients aged 6 to 15 years were classified into the normal eruption group (n = 229) and the impaction group (n = 191). At least two panoramic radiographs were taken in the normal eruption group during the eruption process of the maxillary canine.

In Vitro Investigation of Wear of CAD/CAM Polymeric Materials Against Primary Teeth.

The aim of the study was to evaluate the effects of polymeric computer-aided design/computer-aided manufacturing CAD/CAM materials on antagonistic primary tooth wear. Five CAD/CAM polymeric materials were examined: Vipi Block Monocolor (VBM), Yamahachi polymethylmethacrylate (PMMA) (YAP), Mazic Duro (MZD), Vita Enamic (ENA), and Pekkton (PEK). All of the specimens were tested in a thermomechanical loading machine with the primary canine as the antagonist (50 N, 1.

Indoor air quality assessment in child care and medical facilities in Korea.

In order to characterize the status of indoor air pollution in some important facilities, a list of key criteria pollutants [particulate matter (PM(10)), carbon dioxide (CO(2)), carbon monoxide (CO), formaldehyde (HCHO), and bioaerosol] was measured from a total of 91 randomly selected sites in 18 different cities, Korea (February 2006 to December 2009). The target facilities include 43 child care facilities, 38 medical facilities, 6 elementary schools, and 4 postnatal care centers. The results showed that some air pollutants (e.

Targeted percutaneous transforaminal endoscopic diskectomy in 295 patients: comparison with results of microscopic diskectomy.

Background: The aim of this study is to compare the clinical outcomes and complications after targeted PTED and conventional microscopic diskectomy for removing 1-level unilateral LDH and to evaluate the efficacy of PTED for the treatment of LDH.

Methods: The authors retrospectively examined 915 consecutive patients who underwent PTED (group A, 301 patients) and microscopic diskectomy (group B, 614 patients) for 1-level unilateral LDH. Patients who were treated with a diskectomy in the period from July 2003 to December 2004 were evaluated by telephone interview and institute visit.
