Abstract This is a timely and important review that focuses on the appropriateness of established cleaning, disinfection sterilization methods to safely effectively address infectious fungal drug-resistant pathogens can potentially contaminate reusable medical devices used in healthcare environment order mitigate risk patient infection.

Contamination with (including those FPPL) are rare events more likely occur due cross-transmission arising from lapses hand-hygiene practices.

Dispensable genome and segmental duplications drive the genome plasticity in Fusarium solani

Frontiers in Fungal Biology, Journal Year: 2025, Volume and Issue: 6

Update on diagnosis and treatment of fungal meningitis: lessons from recent outbreaks

Current Opinion in Infectious Diseases, Journal Year: 2024, Volume and Issue: 37(6), P. 437 - 442

Published: Sept. 3, 2024

Purpose of review Recently, fungal meningitis outbreaks have occurred in association with neuraxial and epidural anesthesia immunocompetent patients. Herein, we describe the course those outbreaks, their diagnosis, treatment, prognosis, lessons learned. Recent findings Two Fusarium solani during 2022–2023 were associated two distant cities Mexico (Durango Matamoros). The initial etiological agent identification was delayed due to insensitivity cultures. A qPCR validated positive 38% cerebrospinal fluid (CSF) samples from Durango, while BD-Glucan allowed early diagnosis index case Matamoros. Antifungal treatment voriconazole liposomal amphotericin B (L-AmB) recommended. Overall mortality 51%. Once cause confirmed, some patients received fosmanogepix. Summary Fungal filamentous fungi are usually direct inoculation. They result severe presentations high mortality. Early should be suspected, CSF testing screening is Aggressive antifungal based on susceptibility administered as possible. advent molecular diagnostic methods new drugs may allow for timely increasing chances survival.

Outcomes in solid organ transplant recipients receiving organs from a donor with Fusarium solani species complex meningitis

Transplant Infectious Disease, Journal Year: 2024, Volume and Issue: 26(5)

Published: July 16, 2024

Abstract Background Five organs (heart, right lung, liver, right, and left kidneys) from a deceased patient were transplanted into five recipients in four US states; the was identified as part of healthcare‐associated fungal meningitis outbreak among patients who underwent epidural anesthesia Matamoros, Mexico. Methods After transplant surgeries occurred, Fusarium solani species complex, pathogen with high case‐mortality rate, cerebrospinal fluid organ donor by metagenomic next‐generation sequencing (mNGS) fungal‐specific polymerase chain reaction plasma mNGS. Results Four received recommended voriconazole prophylaxis; monitored weekly serum (1‐3)‐β‐ d ‐glucan testing. All for signs infection at least 3 months following transplantation. The liver recipient had graft failure, which attributed to an etiology unrelated infection. No DNA sections explanted suggesting that F. complex did not contribute failure. remaining experienced no or symptoms suggestive fusariosis. Conclusion Antifungal prophylaxis may be useful preventing donor‐derived infections donors are found have meningitis. image

Neuroinfectious diseases represent a growing threat to public health globally. Infections of the central nervous system remain challenging diagnose and treat, partially driven by fact that high proportion emerging pathogens are capable causing neurological disease. Many trends driving emergence novel pathogens, including climate change, ecological degradation, urbanization, global travel, have accelerated in recent years. These circumstances raise concern for potential additional pandemic coming years, necessitating stronger understanding forces give rise spread neuroinvasive commitment infrastructure identify treat these diseases. In this review, we discuss clinical epidemiological features three types significant consequences emblematic key ongoing health. We first dengue viruses context considering environmental factors allow expansion geographic range seasonal population viruses' vector. then review rising prevalence fungal meningitis secondary medical tourism, trend representative highly globalized nature modern healthcare. Lastly, increasing antibiotic-resistant infections intersection antibiotic overuse agricultural settings. Taken together, conditions necessitates recommitment investment focused on local infectious disease surveillance coupled with development therapeutics vaccines pathogens. Such threats also obviate need address root causes diseases, sustained effort anthropogenic change degradation.
