The increasing burden of group B from 2013 to 2023: a retrospective cohort study in Beijing, China.

Group B (GBS) is a leading pathogen responsible for fatal infections in newborns primarily due to vertical transmission from colonized mothers. Cases of invasive GBS infections in adults have also increased and attracted attention recently. To comprehensively understand the evolving burden of vaginal GBS carriage in pregnant and non-pregnant women, as well as the trends in invasive GBS diseases and antibiotic resistance in China, we conducted a retrospective study using data from a large tertiary hospital in Beijing from 2013 to 2023.

Regulatory Mechanisms and Physiological Impacts of Quorum Sensing in Gram-Negative Bacteria.

The Quorum sensing (QS) system is a widely existing communication mechanism, which regulates bacterial community behaviors and the expression of specific genes. The most common pathogenic bacteria in clinical infections are gram-negative bacteria, and QS plays an important regulatory role in the production of virulence factors and development of antibiotic resistance. This article reviews the QS systems of gram-negative bacteria and provides an overview of how they regulate their physiological functions.

Distinction of clinical features and microbiological methods between and pneumonia confirmed by metagenomic next-generation sequencing.

Using mNGS, we aimed to distinguish psittacosis from legionellosis for early pneumonia diagnosis and better prognosis.

Methods: Thirty-seven patients diagnosed with atypical CAP were enrolled in this retrospective study, including 14  pneumonia and 23 () pneumonia.

Methods: This retrospective study included critically ill non-HIV immunocompromised patients admitted to a medical ICU with suspected pneumonia, undergoing simultaneous microbiological testing for P.

Geneticand phenotypic characterization of a novel ST45-K43 carbapenem-resistant strain causing bloodstream infection: a potential clinical threat.

is a common pathogen of nosocomial infection, which can cause pneumonia, urinary tract infection, cystitis, and bloodstream infections (BSIs). Here, we genetically characterize a novel carbapenem-resistant (CRKP) strain recovered from the blood of a 44-year-old male patient with severe acute necrotizing pancreatitis and septic shock in China. The strain is a ST45 with a novel serotype of K43, named 18SHX166.

The key role of iroBCDN-lacking pLVPK-like plasmid in the evolution of the most prevalent hypervirulent carbapenem-resistant ST11-KL64 Klebsiella pneumoniae in China.

Aims: Hypervirulent carbapenem-resistant Klebsiella pneumoniae (hv-CRKP), coharboring hypervirulence and carbapenem-resistance genes mediated by plasmids, causes infections with extremely high mortality and seriously impacts public health. Exploring the transfer mechanisms of virulence/carbapenem-resistance plasmids, as well as the formation and evolution pathway of hv-CRKP is of great significance to the control of hv-CRKP infections.

Methods: In this study, we identified the predominant clone of hv-CRKP in China and elucidated its genomic characteristics and formation route based on 239 multicenter clinical K.

The role of coffee and potential mediators in subclinical atherosclerosis: insights from Mendelian randomization study.

In this Mendelian randomization study, we investigated whether genetically predicted coffee consumption is associated with subclinical atherosclerosis, as well as the role of potential mediators.

Methods: We first conducted a two-sample Mendelian randomization analysis to examine the causal effect of coffee and its subtypes on subclinical atherosclerosis inferred from coronary artery calcification (CAC).

Synthesis, Crystal Structures and Catalytic Oxidation Property of Two Oxidovanadium(V) Complexes with Schiff bases.

Two new oxidovanadium(V) complexes, [VO2L1] (1) and [V2O2(μ-O)2L2)] (2), where L1 and L2 are the deprotonated form of 5-bromo-2-(((2-(pyrrolidin-1-yl)ethyl)imino)methyl)phenol (HL1) and 5-bromo-2-(((2-((2-hydroxyethyl)amino)ethyl)imino)methyl)phenol (HL2), respectively, have been synthesized and structurally characterized by physico-chemical methods and single crystal X-ray determination. X-ray analysis indicates that the V atom in complex 1 is in square pyramidal coordination, and those in complex 2 are in octahedral coordination. Crystal structures of the complexes are stabilized by hydrogen bonds.

Effect of ceftazidime-avibactam combined with different antimicrobials against carbapenem-resistant .

Metabolic changes before and after weaning in Dezhou donkey foals in relation to gut microbiota.

Weaning is undoubtedly one of the most crucial stages in the growth and development of all mammalian animals, including donkey foals. Weaning is a dynamic and coordinated process of the body, which is closely associated with the health, nutrition, and metabolism of the host. Many studies have shown that the intestinal microbiota and serum metabolites of mammals exhibit different changes during lactation, weaning, and postweaning.

Genome-wide analyses based on a novel donkey 40K liquid chip reveal the gene responsible for coat color diversity in Chinese Dezhou donkey.

Dezhou donkey is one of the representative local breeds in China, which is mainly divided into two strains: Sanfen and Wutou. There are obvious differences in coat color between the two strains. The former shows light points around the eyes, around the muzzle and under the belly, while the latter is completely solid black.

Protective effects and mechanism of curcumin in animal models of pulmonary fibrosis: a preclinical systematic review and meta-analysis.

At present, there is a lack of effective treatment for pulmonary fibrosis (PF), and a number of studies have confirmed that curcumin (CUR) has a good effect on PF. Is CUR effective in preclinical trials for PF and what is its mechanism of action? Animal reports of PF treated with CUR were searched from Pubmed, Embase, Web of Science and Cochrane Library from 1 January 2000 to 19 April 2023 to compare CUR treatment of PF with a no-intervention model group. A previous registration (nsply registration number: INPLASY202360084) of this review protocol was undertaken.
