Identification and analysis of a clinically isolated strain of Halomonas based on whole-genome sequencing and comparative genomics.

Objective: The aim of this study was to identify the species of a Halomonas strain isolated from a neonatal blood sample and to understand the potential pathogenicity and characteristic genes of the strain.

Methods: The genomic DNA of strain 18071143 (identified as Halomonas by matrix-assisted laser desorption-ionization time of flight-mass spectrometry and the 16S ribosomal RNA (rRNA) gene sequence) was sequenced using Nanopore PromethION platforms. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) were calculated using the complete genome sequences of the strain.

Impact of COVID-19 pandemic on influenza virus prevalence in children in Sichuan, China.

We performed a retrospective analysis of influenza A and B virus antigen detection data in children in Sichuan Province from January 2019 to December 2021, with the goal of studying the impact of the COVID-19 pandemic on influenza circulation in children in Sichuan, China. During the pandemic, both the number of specimens and the positive rates of the influenza virus fell dramatically. The positivity for influenza A virus decreased from 22.

An imbalanced ratio between PC(16:0/16:0) and LPC(16:0) revealed by lipidomics supports the role of the Lands cycle in ischemic brain injury.

Promoting brain recovery after stroke is challenging as a plethora of inhibitory molecules are produced in the brain preventing it from full healing. Moreover, the full scope of inhibitory molecules produced is not well understood. Here, using a high-sensitivity UPLC-MS-based shotgun lipidomics strategy, we semiquantitively measured the differential lipid contents in the mouse cerebral cortex recovering from a transient middle cerebral artery occlusion (MCAO).

Integrative analysis provides multi-omics evidence for the pathogenesis of placenta percreta.

Pernicious placenta previa with placenta percreta (PP) is a catastrophic condition during pregnancy. However, the underlying pathogenesis remains unclear. In the present study, the placental tissues of normal cases and PP tissues of pernicious placenta previa cases were collected to determine the expression profile of protein-coding genes, miRNAs, and lncRNAs through sequencing.

Molecular Characteristics of Methicillin-Resistant Staphylococcus epidermidis on the Abdominal Skin of Females before Laparotomy.

Staphylococcus epidermidis, especially methicillin-resistant strains, may be the source of surgical site infections and may be a reservoir of staphylococcal cassette chromosome mec (SCCmec) for S. aureus. The aim of this study was to investigate the prevalence of methicillin-resistant S.

Anti-Trichomonas vaginalis properties of the oil of Amomum tsao-ko and its major component, geraniol.

Context: Trichomonosis, caused by the flagellate protozoan Trichomonas vaginalis, is the most common non-viral sexually transmitted disease (STD) and 5-nitroimidazole drugs are used for the treatment. However, a growing number of T. vaginalis isolates are resistant to these drugs, which make it becomes an urgent issue.

[Mycoplasma hominis symbiosis and Trichomonas vaginalis metronidazole resistance].

Objective: To investigate the relation of Mycoplasma hominis symbiosis and the resistance of Trichomonas vaginalis to metronidazole.

Methods: From November 2010 to July 2011, 160 isolates of T. vaginalis were collected from the genital tract secretion of gynecological out-patients at the Sichuan Provincial Hospital for Women and Children.

[Influence of bifidobacterial whole peptidoglycan on cellular immune response induced by recombinant HBsAg].

Aim: To explore the effect of bifidobacterial whole peptidoglycan (BWPG) on cellular immune response to recombinant hepatitis B surface antigen (rHBsAg).

Methods: BWPG was used as an adjuvant of rHBsAg to immunize BALB/c mice. The growth state and development of central lymphoid organ of immunized mice were observed.
