Hand hygiene01:23

Hand hygiene

6.6K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Antimicrobial Effectiveness01:28

Antimicrobial Effectiveness

2.0K
The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

Antimicrobial Proteins

15.4K
Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
Interferons
Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...

Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...

Chemical Agents for Microbial Control

1.5K
Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

Surface Membrane Barriers01:18

Surface Membrane Barriers

3.3K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Area of Science:

  • Microbiology
  • Polymer Science
  • Healthcare Infection Control

Background:

  • Hospital-acquired infections are a significant concern, often spread through direct contact.
  • Healthcare workers face challenges adhering to strict hand disinfection protocols.
  • Effective infection prevention, particularly hand hygiene, is crucial in nosocomial settings.

Purpose of the Study:

  • To develop an innovative hand rub with antimicrobial properties.
  • To create a protective film on the hands, termed a "microglove," to improve hand hygiene.
  • To enhance compliance with infection prevention measures in healthcare environments.

Main Methods:

  • Formulation of co-polymers using Polyvinylpyrrolidone (PVP) and a branched C20 derivatized maleate (M20) at various ratios.
  • Incorporation of the biocide benzalkonium chloride (BKC) into the co-polymer formulations.
  • Evaluation of combined film-forming and antimicrobial activities using novel contamination and transmission assays.

Main Results:

  • Several co-polymer formulations with BKC were tested for efficacy.
  • A specific formulation demonstrated promising film-forming and antimicrobial properties.
  • The optimal formulation consisted of 80% PVP and 20% M20 co-polymer with 0.9% BKC.

Conclusions:

  • The developed antimicrobial microglove formulation meets the basic requirements for effective hand hygiene.
  • This innovation offers a potential solution to improve healthcare worker compliance with hand disinfection.
  • The microglove technology could significantly contribute to reducing the spread of infections in hospitals.
