Candida Auris and Antifungal Resistance: The Need for New Strategies
Candida Auris: The Emerging Multidrug-Resistant Fungus
Candida auris is an emerging fungal pathogen that has become a global health threat due to its resistance to multiple antifungal drugs. It was first identified in 2009 in Japan, and since then, it has been identified in several countries, including the United States, India, South Africa, and the United Kingdom. Candida auris has been responsible for outbreaks of infections in healthcare settings, and it has a higher mortality rate than other Candida species.
What is Candida Auris?
Candida auris is a type of yeast that belongs to the Candida family, which includes other well known fungal pathogens such as Candida albicans and Candida glabrata. Like other Candida species, Candida auris is part of the normal flora of the human body, and it is commonly found in the skin, mouth, and gut. However, unlike other Candida species, Candida auris is resistant to multiple antifungal drugs, which makes it difficult to treat infections caused by this pathogen.
How does Candida auris spread?
Candida auris is primarily transmitted in healthcare settings, such as hospitals and nursing homes. The fungus can survive on surfaces for long periods of time, which increases the risk of transmission from contaminated surfaces. Additionally, people who are colonized with Candida auris can spread the fungus to others through direct contact or through contaminated surfaces.
What are the symptoms of Candida auris infection?
Candida auris can cause a variety of infections, including bloodstream infections, wound infections, and ear infections. The symptoms of Candida auris infection depend on the type of infection and the location of the infection. In general, the symptoms of Candida auris infection are similar to those caused by other Candida species, and they may include fever, chills, rash, and fatigue.
How is Candida auris diagnosed?
Diagnosing Candida auris infection can be challenging because it is often misidentified as other Candida species. Additionally, traditional laboratory methods may not be able to detect Candida auris, which can lead to delayed diagnosis and treatment. Therefore, it is important to use specialized laboratory techniques, such as matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF), to accurately identify Candida auris.
How is Candida auris treated?
Treating Candida auris infection can be difficult because the fungus is resistant to multiple antifungal drugs. However, there are still some antifungal drugs that are effective against Candida auris, such as echinocandins and amphotericin B. In some cases, combination therapy may be necessary to treat Candida auris infection.
Preventing Candida auris transmission
Preventing the transmission of Candida auris in healthcare settings is critical to controlling outbreaks of infections caused by this pathogen. Healthcare facilities should implement strict infection control measures, such as hand hygiene, contact precautions, and environmental cleaning, to prevent the spread of Candida auris. Additionally, screening patients for colonization with Candida auris can help identify and isolate patients who are at risk of spreading the fungus.
Conclusion
Candida auris is an emerging multidrug-resistant fungal pathogen that poses a serious threat to public health. It is capable of causing invasive infections and has a higher mortality rate than other Candida species. The emergence of Candida auris highlights the need for increased surveillance, research, and development of antifungal drugs to combat this emerging pathogen. Additionally, healthcare facilities must implement strict infection control measures to prevent the transmission of Candida auris in healthcare settings.
