Summary
Common disinfectants effectively control Nannizziopsis arthrosporioides, a fungus causing reptile infections. Bleach, chlorhexidine, and other cleaners inactivated the pathogen, aiding in reptile disease prevention.
Area of Science:
- Mycology
- Veterinary Dermatology
- Infectious Diseases
Background:
- Nannizziopsis arthrosporioides is a keratinophilic fungus responsible for infections in various reptile species.
- Effective disinfection protocols are crucial for managing Nannizziopsis infections in reptiles.
Purpose of the Study:
- To evaluate the efficacy of common commercial disinfectants against Nannizziopsis arthrosporioides.
- To provide data supporting appropriate disinfection strategies for reptile fungal pathogens.
Main Methods:
- Two confirmed isolates of Nannizziopsis arthrosporioides were cultured.
- Conidial suspensions were exposed to various disinfectants (bleach, multipurpose cleaner, chlorhexidine, F10 SC, povidone-iodine, Rescue) for 5 or 10 minutes.
- Fungal growth was assessed post-exposure.
Main Results:
- Commercial bleach, 409 multipurpose cleaner, chlorhexidine, povidone-iodine, and Rescue disinfectant completely inhibited fungal growth.
- F10 SC showed variable inhibition of Nannizziopsis arthrosporioides growth.
- No growth was observed for either isolate after exposure to most tested disinfectants.
Conclusions:
- Several commercially available disinfectants are effective in inactivating Nannizziopsis arthrosporioides.
- This study contributes valuable data for establishing effective disinfection practices against reptile fungal pathogens.

01:28Antimicrobial 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...
01:23Hand 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.
