Detection of Antibiotic Resistance and Analysis of Resistance Genes and Virulence Genes of Salmonella Isolated from Human.

Salmonella is a food-borne pathogen that can cause zoonoses. The emergence of drug-resistant strains of Salmonella is of great concern. It is necessary to understand the prevalence of antibiotic resistance, antibiotic resistance genes and virulence genes in human Salmonella.

Biofilm-forming ability of Salmonella enterica strains of different serotypes isolated from multiple sources in China.

Salmonella is an important zoonotic and foodborne pathogen that can infect humans and animals, causing severe concerns about food safety and a heavy financial burden worldwide. The pathogen can adhere to living and abiotic surfaces by forming biofilms, which increases the risk of transmission and infection. In this study, we investigated the biofilm-forming ability of 243 Salmonella strains of 36 serotypes from different sources in China using microplate crystal violet staining method.

Genomic typing and virulence gene profile analysis of Salmonella Derby from different sources.

Salmonella enterica serovar Derby (S. Derby) is one of the most common Salmonella serovars which can infect poultry, swine, and humans. With the reduction of the sequencing cost and the improvement of sequencing technology, whole genome sequencing (WGS) has become an important method for bacterial determination, molecular investigation, and pathogenic tracing analysis.

Genomes-based MLST, cgMLST, wgMLST and SNP analysis of Salmonella Typhimurium from animals and humans.

Salmonella Typhimurium (S. Typhimurium) is an important food-borne and zoonotic pathogen that causes salmonellosis. With the development of whole genome sequencing (WGS), genome-based typing has been widely applied to bacteriology.

Genomic virulence genes profile analysis of Salmonella enterica isolates from animal and human in China from 2004 to 2019.

Salmonella is a momentously zoonotic and food-borne pathogen that seriously threats human and animal health around the world. Salmonella pathogenicity is closely related to its virulence genes profile. However, conventional virulence gene analysis methods cannot truly reveal whole virulence genes carried by Salmonella.

Prognosis and weaning of elderly multiple organ dysfunction syndrome patients with invasive mechanical ventilation.

Background: Elderly multiple organ dysfunction syndrome (MODS) patients receiving invasive mechanical ventilation have poor prognosis in intensive care units (ICUs). We studied the usefulness of four commonly used severity scores and extrapulmonary factors that affected weaning to predict outcome of such patients.

Methods: Clinical data of 197 patients on admission to ICUs (from January 2009 to June 2012) were used retrospectively.

[Assessment of prognostic and influencing factors in elderly patients with multiple organ dysfunction syndrome].

Objective: To preliminarily assess the prognosis of patients with multiple organ dysfunction syndrome (MODSE) and analyze their influencing factors.

Methods: The clinical data of 365 MODSE patients admitted into Chinese PLA General Hospital during January 2009 to June 2012 were analyzed retrospectively. According to 28-day outcomes, they were divided into 2 groups (28-day survival and non-survival) while 4 groups according to age.

Significance of low serum vitamin D for infection risk, disease severity and mortality in critically ill patients.

Background: Hospitalized patients often have higher rate of vitamin D deficiency than healthy people. Vitamin D levels below normal are associated with hospital stay, increased incidence of adverse prognosis and increased mortality of a number of diseases. Whether there is a relationship between vitamin D levels and infection or sepsis in the critically ill is still unclear.

Identification of novel biomarkers for sepsis prognosis via urinary proteomic analysis using iTRAQ labeling and 2D-LC-MS/MS.

Objectives: Sepsis is the major cause of death for critically ill patients. Recent progress in proteomics permits a thorough characterization of the mechanisms associated with critical illness. The purpose of this study was to screen potential biomarkers for early prognostic assessment of patients with sepsis.

Diagnostic value of urine sCD163 levels for sepsis and relevant acute kidney injury: a prospective study.

Background: Sepsis is a common syndrome in critically ill patients and easily leads to the occurrence of acute kidney injury (AKI), with high mortality rates. This study aimed to investigate the diagnostic value of urine soluble CD163 (sCD163) for identification of sepsis, severity of sepsis, and for secondary AKI, and to assess the patients' prognosis.

Methods: We enrolled 20 cases with systemic inflammatory response syndrome (SIRS), 40 cases with sepsis (further divided into 17 sepsis cases and 23 severe sepsis cases) admitted to the intensive care unit (ICU), and 20 control cases.

Value of soluble TREM-1, procalcitonin, and C-reactive protein serum levels as biomarkers for detecting bacteremia among sepsis patients with new fever in intensive care units: a prospective cohort study.

Background: The purpose of this study was to explore the diagnostic value of soluble triggering receptor expressed on myeloid cells 1 (sTREM-1), procalcitonin (PCT), and C-reactive protein (CRP) serum levels for differentiating sepsis from SIRS, identifying new fever caused by bacteremia, and assessing prognosis when new fever occurred.

Methods: We enrolled 144 intensive care unit (ICU) patients: 60 with systemic inflammatory response syndrome (SIRS) and 84 with sepsis complicated by new fever at more than 48 h after ICU admission. Serum sTREM-1, PCT, and CRP levels were measured on the day of admission and at the occurrence of new fever (>38.

Dynamic changes in serum soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) and its gene polymorphisms are associated with sepsis prognosis.

This study explored the association of sepsis prognosis with dynamic changes in serum soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) and its polymorphisms. We enrolled 80 subjects with sepsis and 80 controls. Serum sTREM-1 was tested on days 1, 3, 5, 7, 10, and 14.
