AI Article Synopsis

  • * Researchers utilized techniques like NG-mast and serum bactericidal assays to analyze 46 isolated strains from STD clinic patients, identifying varying gene combinations among them.
  • * The findings revealed that while 80.43% of strains had specific genetic islands, there was no link between the presence of the sac-4 gene and serum resistance against Neisseria gonorrhoeae.

Article Abstract

Objective: Using molecular methods to study the relationship between genotypes and serum resistance of Neisseria gonorrhoeae in Wuhan area.

Methods: NG-mast and serum bactericidal assays at the molecular level were used to differentiate the 46 strains which were isolated from the outpatients of sexually transmitted disease clinics and the relationship between different genotypes while phenotypes was also studied.

Results: 80.43% of the 46 strains contained the island and we were able to define three different combinations of genes in the isolates. Results from serum bactericidal assays showed that all 9 sac-4+ strains did not provide any serum resistance.

Conclusion: Different isolates carried different gonococcal genetic islands (pathogenicity island) and certain phenotypes. There were no sobious relationship between sac-4 gene and serum resistance of Neisseria gonorrhoeae.

The newly emerged variants of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) demonstrate resistance to present therapeutic antibodies as well as the capability to evade vaccination-elicited antibodies. JN.1 sublineages were demonstrated as one of the most immune-evasive variants, showing higher neutralization resistance compared to XBB.

Introduction: The escalating resistance of microorganisms to antimicrobials poses a significant public health threat. Strategies that use biomarkers to guide antimicrobial therapy-most notably Procalcitonin (PCT) and C-reactive protein (CRP)-show promise in safely reducing patient antibiotic exposure. While CRP is less studied, it offers advantages such as lower cost and broader availability compared with PCT.

Noninvasive evaluations of hormones can contribute to the assessment of health and welfare of animals. Variations in insulin levels and sensitivity, for example, have been linked to health concerns in non-human and human primates including insulin resistance, diabetes, and heart disease, the leading cause of death in zoo-housed gorillas. Few published studies have assessed insulin concentrations in western lowland gorillas (Gorilla gorilla gorilla), and all did so using serum.

Unlabelled: The complement cascade is a front-line defense against pathogens. Complement activation generates the membrane attack complex (MAC), a 10-11 nm diameter pore formed by complement proteins C5b through C8 and polymerized C9. The MAC embeds within the outer membrane of Gram-negative bacteria and displays bactericidal activity.
