Nanoplastics and Antibiotic Resistance Blog Image

Overview:

A recent study has highlighted that nanoplastics derived from single-use plastic bottles (SUPBs) contribute to the spread of antibiotic resistance (AR).

Understanding Antibiotic Resistance (AR)

  • Definition: AR is a type of antimicrobial resistance where bacteria evolve to withstand the effects of antibiotics, making infections harder to treat.
  • Mechanism: It occurs primarily due to genetic changes that allow bacteria to neutralize or evade drugs designed to kill them.

Key Findings of the Study

  • Impact on Gut Microbiome: Nanoplastics can transform Lactobacillus acidophilus, a beneficial gut microbiota, into a carrier of AR genes.
    • These AR genes can be transferred to pathogenic bacteria, exacerbating the AR crisis.
  • Horizontal Gene Transfer (HGT):
    • Polyethylene terephthalate bottle-derived nanoplastics (PBNPs) facilitate the transfer of AR genes from E. coli to Lactobacillus acidophilus via HGT.
    • HGT involves gene transfer across different bacterial species, unlike vertical gene transfer, which occurs from parent to offspring.
  • Mechanisms of AR Gene Transfer:
    • Direct Transformation Pathway: PBNPs act as physical carriers, transporting AR plasmids across bacterial membranes. This facilitates direct gene transfer between bacteria.
    • OMV-Induced Transfer Pathway: PBNPs induce oxidative stress, triggering an increased secretion of outer membrane vesicles (OMVs). These OMVs, loaded with AR genes, serve as potent vectors for gene transfer between bacterial species, including beneficial and pathogenic bacteria.

What Are Nanoplastics?

  • Definition: Nanoplastics are solid particles of synthetic or heavily modified natural polymers, ranging in size from 1 nm to 1000 nm.
  • Types:
    • Primary Nanoplastics: Intentionally produced for specific applications.
    • Secondary Nanoplastics: Generated from the fragmentation of larger plastics, often released unintentionally into the environment.

Q1: What are nanoparticles, and why are they important?

Nanoparticles are ultra-small particles with dimensions typically between 1 and 100 nanometers. Due to their tiny size and high surface area-to-volume ratio, they exhibit unique physical, chemical, and biological properties, making them valuable in diverse fields like medicine, electronics, environmental science, and materials engineering.

News: Nano-plastics identified as emerging agents in spread of antibiotic resistance.

Northern giant hornet Blog Image

Overview:

The Department of Agriculture of the United States said that it has eradicated the Northern giant hornet, nicknamed the “murder hornet”.

About Northern giant hornet: 

  • Scientific name: Vespa mandarinia
  • It is the largest hornet in the world, measuring up to 2 inches long. 
  • Habitat: They are known for inhabiting the lower altitude forest and avoiding large plains and high-altitude regions.
  • Distribution: They are native to temperate regions in China, Korea, Japan, and India.
  • It is an invasive species which poses a significant threat to insects and native pollinators.

GLP-1 Receptor Agonists Blog Image

Overview:

Scientists at the World Health Organisation (WHO) have endorsed a new class of medicines known as GLP-1 receptor agonists.

About GLP-1 Receptor Agonists: 

  • Glucagon-Like Peptide (GLP)-1 receptor agonists mimic a hormone that regulates appetite and blood sugar levels, for managing obesity.
  • By specifically binding to the key hormone GLP-1, it regulates blood glucose levels and lipid metabolism.
  • This receptor and its agonists hold significant therapeutic potential, reshaping the treatment approaches for multiple diseases, including diabetes, cardiovascular disorders, and neurodegenerative diseases.
  • GLP-1 agonists are most often injectable medications, meaning you inject a liquid medication with a needle and syringe. 
  • The new class of GLP-1 receptor agonists, that included drugs such as semaglutide and tirzepatide, “have the potential to be transformative.
    • In medication terms, an agonist is a manufactured substance that attaches to a cell receptor and causes the same action as the naturally occurring substance. 

What is GLP-1?

  • GLP-1 is a key hormone that plays an integral role in regulating blood glucose levels, lipid metabolism, and several other crucial biological functions. 
  • It is released by the intestines in response to food intake. 

Q1: What is Diabetes?

It is a chronic disease that occurs either when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin it produces.
