Insights

Class 1 integrons are emerging as key drivers of antibiotic resistance in methicillin-resistant staphylococci (MRS). This review details their prevalence and role in conferring resistance in these critical Gram-positive pathogens.

Area of Science:

  • Microbiology
  • Molecular Biology
  • Public Health

Background:

  • Methicillin-resistant staphylococci (MRS) are a significant public health concern, causing prevalent nosocomial infections globally.
  • MRS are recognized as

Purpose of the Study:

  • To review the prevalence and characteristics of class 1 integrons in clinical MRS isolates.
  • To analyze the association between class 1 integrons and antibiotic resistance in MRS.
  • To investigate the role and evolution of integrons as determinants of antimicrobial resistance in Gram-positive bacteria.

Main Methods:

  • Systematic investigation of integrons in hundreds of staphylococci strains between 2001 and 2006.
  • Review of existing literature on class 1 integrons in Gram-negative and Gram-positive bacteria.
  • Analysis of prevalence, occurrence, and correlation with antibiotic resistance.

Main Results:

  • Class 1 integrons are identified as a novel antibiotic resistance mechanism, primarily studied in Gram-negative organisms.
  • Limited knowledge exists regarding integrons in clinical Gram-positive bacteria like MRS.
  • This review focuses on the development, prevalence, and role of class 1 integrons in MRS.

Conclusions:

  • Class 1 integrons play a significant role in the antibiotic resistance of MRS.
  • Further research into integrons in Gram-positive bacteria is crucial for understanding and combating antimicrobial resistance.
  • Surveillance of integrons in clinical MRS strains is of utmost importance for public health.

Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...

Stringent Response in E. coli

Bacterial growth is closely tied to nutrient availability, with cells proliferating exponentially under favorable conditions and entering a stationary phase when resources become scarce. This transition is mediated by a regulatory mechanism known as the stringent response, which allows bacteria to adapt to nutrient deprivation by modulating gene expression and metabolic activity.During nutrient scarcity, intracellular amino acid levels decline. It results in the accumulation of uncharged tRNAs...
Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
Integrins01:10

Integrins

Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...
Conjugation01:19

Conjugation

Conjugation is a form of horizontal gene transfer that primarily occurs in bacteria and some archaea, promoting genetic diversity and adaptation. Bacteria can acquire resistance genes through conjugative plasmids, allowing them to survive antibiotic treatments that would otherwise be lethal. This process involves direct contact between cells through specialized structures such as the sex pilus and is mediated by conjugative plasmids, including the F (fertility) factor.Conjugation requires...
