Mucor germinans, a novel dimorphic species resembling Paracoccidioides in a clinical sample: questions on ecological strategy

mycolabadmin

Researchers discovered a new fungus called Mucor germinans that infected a cancer patient’s lungs and appeared as yeast cells rather than the typical thread-like fungal structures. This is unusual because Mucor infections normally show filamentous hyphae, and the yeast-like appearance made it look like a different fungus, potentially delaying correct diagnosis and treatment. The study shows that this fungus can change forms depending on temperature and other conditions, and identifying it requires checking for multiple nuclei in the cells to distinguish it from other similar-looking yeasts.

Epidemiology of mucormycosis in COVID-19 patients in northwest Iran: Rhizopus arrhizus as the predominant species

mycolabadmin

During the COVID-19 pandemic, some patients developed a severe fungal infection called mucormycosis alongside their coronavirus infection. This study found that 63 COVID-19 patients in Iran developed mucormycosis, which primarily affected the sinuses and brain. The researchers identified that a fungus called Rhizopus arrhizus caused most infections, and patients who received corticosteroids (used to treat severe COVID-19) had a higher risk, especially those who developed diabetes from the steroids.

The first report of rhinosinusitis by Rhizopus delemar in a patient with severe COVID-19 in Iran: a case report

mycolabadmin

A 63-year-old man hospitalized with COVID-19 developed a serious fungal sinus infection caused by a rare mold called Rhizopus delemar. Despite surgery to remove infected tissue and treatment with antifungal medication amphotericin B, the infection spread and the patient died after five weeks. This was the first documented case of this particular mold causing sinus infection in a COVID-19 patient in Iran, highlighting how severe fungal infections can occur as dangerous complications of COVID-19.

Disseminated Lichtheimia ramosa infection in a Japanese Black calf

mycolabadmin

A young beef calf developed severe diarrhea and fever that did not respond to multiple antibiotics. The calf had an underdeveloped immune system (missing thymus gland) and was treated with many antibiotics and steroids, which weakened its immune system further. After death, examination revealed the calf had a widespread fungal infection caused by Lichtheimia ramosa in the liver and digestive tract, representing the first documented case of this type in Japanese Black cattle.

Mucor germinans, a novel dimorphic species resembling Paracoccidioides in a clinical sample: questions on ecological strategy

mycolabadmin

Researchers identified a new fungal species called Mucor germinans from a patient with Burkitt lymphoma that can switch between filamentous and yeast-like forms. This is unusual because Mucor species are typically identified by their thread-like filaments, not budding yeast cells. The yeast form appeared at body temperature and resembled a different fungus called Paracoccidioides, potentially causing misdiagnosis. The discovery emphasizes the importance of recognizing that some Mucor infections may present with yeast-like cells and highlights the need for rapid, accurate identification to guide appropriate antifungal treatment.

Rhino-orbital-cerebral mucormycosis in diabetic ketoacidosis: A classic clinical presentation still unknown in Senegal

mycolabadmin

A young woman in Senegal with uncontrolled diabetes developed a serious fungal infection affecting her eye and brain caused by Rhizopus oryzae. Despite showing classic warning signs like swelling and tissue death, the infection was not diagnosed quickly enough, and the necessary antifungal medication (amphotericin B) was not available, resulting in her death within three days. This case highlights how invasive fungal infections are underrecognized and undertreated in Africa due to limited laboratory capacity and drug availability.

Molecular epidemiology, diversity, and antifungal susceptibility profiles of clinical and environmental mucorales: a five-year multicenter study in Iran (2018–2023)

mycolabadmin

This study examined dangerous mold infections called mucormycosis that became more common during the COVID-19 pandemic, particularly in Iran. Researchers tested over 180 fungal samples from patients and soil to understand which types of molds cause infections and which antifungal medicines work best against them. They found that two medicines, amphotericin B and posaconazole, were most effective, while fungi from soil samples were often more resistant to treatment than those from infected patients. This research helps doctors choose the right treatments for patients with these serious infections.

Gastrointestinal and Intra-Abdominal Mucormycosis in Non-Haematological Patients—A Comprehensive Review

mycolabadmin

This review examines a serious but rare fungal infection called mucormycosis that affects the stomach and intestines. The infection most commonly occurs in patients with diabetes, those who have received organ transplants, or those in intensive care units. Diagnosis can be difficult because symptoms are non-specific, but prompt treatment with antifungal medications and surgery when possible significantly improves survival rates. Early recognition and rapid diagnosis are critical for patients to have the best outcomes.

Efficacy of SCY-247, a Second-generation Triterpenoid Antifungal, in Three Murine Models of Invasive Fungal Infections

mycolabadmin

Researchers tested a new antifungal drug called SCY-247 in mice to treat serious fungal infections. The drug was given orally and showed strong effectiveness against common fungal infections caused by Candida and Rhizopus species, including strains resistant to current treatments. Higher doses of the drug produced better results, and the drug effectively concentrated in the organs most affected by fungal infections.

Invasive Cutaneous Mucormycosis in a Patient With Chronic Lymphocytic Leukemia on Obinutuzumab, Idelalisib, and Bruton Tyrosine Kinase Degrader: A Case Report

mycolabadmin

A 74-year-old man with leukemia developed a serious fungal infection (mucormycosis) on his ankle while taking cancer-fighting drugs. The infection was diagnosed through tissue biopsy examination rather than standard culture tests. Treatment required both powerful antifungal medications and surgical removal of the infected leg below the knee. The patient recovered successfully after this aggressive treatment approach.
