Hand hygiene

Hand hygiene

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 Effectiveness

Antimicrobial Effectiveness

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...

Area of Science:

Parasitology
Medicinal Chemistry
Biochemistry

Background:

Chagas disease, caused by Trypanosoma cruzi, poses a significant global health challenge affecting millions.
Understanding trypanocidal mechanisms is crucial for developing effective treatments.
Natural endoperoxides, like ergosterol peroxide, show promise as antiparasitic agents with low host toxicity.

Purpose of the Study:

To elucidate the cellular and molecular mechanisms of ergosterol peroxide's trypanocidal activity against Trypanosoma cruzi.
To identify the specific cytotoxic pathway triggered by ergosterol peroxide in T. cruzi.

Main Methods:

Employed a multidisciplinary approach combining biochemical assays, microscopy, and in silico analyses.
Investigated the effects of ergosterol peroxide derived from Pleurotus ostreatus on T. cruzi.
Focused on identifying free-radical generation and its downstream effects on parasite viability.

Main Results:

Demonstrated that ergosterol peroxide induces a free-radical reaction within T. cruzi.
This free-radical generation leads to parasite cell death, indicating a novel cytotoxic mechanism.
The study provides the first detailed identification of the molecular cytotoxic pathway for this natural compound.

Conclusions:

Ergosterol peroxide exerts its trypanocidal effect on T. cruzi via a free-radical mediated mechanism.
This research clarifies the molecular basis of ergosterol peroxide's toxicity to the parasite.
Findings contribute to the development of novel therapeutic strategies against Chagas disease.
