Most COVID-19-associated mucormycosis (CAM) cases are reported from India and neighbouring countries. Anecdotally Europe have been presented.To estimate the disease burden describe clinical presentation of CAM in Germany.We identified through German mycology networks scientific societies, collected anonymised information via FungiScope®.We 13 six tertiary referral hospitals diagnosed between March 2020 June 2021. Twelve patients had severe or critical COVID-19, eleven were mechanically...

Abstract Between April and June 2020, i.e., during the first wave of pandemic coronavirus disease 2019 (COVID-19), 55 patients underwent long-term treatment in intensive care unit at University Hospital Regensburg. Most them were transferred from smaller hospitals, often due to need for an extracorporeal membrane oxygenation system. Autopsy was performed 8/17 COVID-19-proven after (mean: 33.6 days). revealed that typical pathological changes occurring early stages (e.g., thrombosis,...

Infection and inflammation are able to induce diet-independent Na+-accumulation without commensurate water retention in afflicted tissues, which favors the pro-inflammatory activation of mouse macrophages augments their antibacterial antiparasitic activity. While Na+-boosted host defense against protozoan parasite Leishmania major is mediated by increased expression leishmanicidal NOS2 (nitric oxide synthase 2, inducible), molecular mechanisms underpinning this enhanced with high Na+ (HS)...

Abstract Introduction In Germany, the growing incidence of invasive fungal infections (IFIs) is a significant health concern, particularly impacting individuals with compromised immune systems due to factors like increasing transplant recipients, an ageing population, and heightened use immunosuppressive medications. Diagnosing IFI remains challenging, integration biomarker assays into clinical practice difficult. Antifungal resistance, exemplified by pan-antifungal-resistant Candida auris...

Abstract We present four cases with Gram-positive bacteremia (pathogens: MRSA n = 1 , Enterococcus spp. 3) due to an intravascular source (left ventricular assist device: 2, transfemoral aortic valve implantation 1, prosthetic valve: 1) where no curative treatment was available. These patients received indefinite, chronic suppressive (palliative) therapy dalbavancin (500 mg weekly or 1000 biweekly regimens). Outcomes and clinical characteristics are described; effective in suppression of all...

Community-acquired pneumonia due to Pseudomonas aeruginosa in previously healthy individuals is a rare disease that associated with high fatality. On 14 February 2010 49-year-old woman presented an emergency room signs and symptoms of pneumonia, 2 days after returning from spa holiday wellness hotel. Blood cultures respiratory specimens grew P. aeruginosa. Despite adequate antimicrobial therapy, the patient died septic multiorgan failure on day nine hospitalization. 26, water samples were...

Fungal implant-associated bone infections are rare but difficult to treat and often associated with a poor outcome for patients. Candida species account approximately 90% of all fungal infections. In vivo biofilm models play major role study development potential new treatment options; however, there only very few in fungi-associated biofilms. Furthermore, mammalian infection replaced more due ethical restrictions other alternative basic research. Recently, we developed an insect model...
