Case Report: Aspergillosis and Cyathostoma americana co-infection in the lower respiratory tract of a Harris’s Hawk (Parabuteo unicinctus)

mycolabadmin

A 12-year-old Harris’s Hawk died from a rare combination of two serious infections affecting its lungs and air sacs: a fungal infection (Aspergillus fumigatus) and a parasitic worm infection (Cyathostoma americana). This is the first documented case of these two infections occurring together in a hawk. The worms and fungus caused severe inflammation and tissue damage, ultimately leading to the bird’s death. This case highlights how multiple infections can work together to make disease more severe in captive birds of prey.

Morphological and Phylogenetic Characterization of Endophytic Fungi Isolated from Brown Algae (Phaeophyceae) in Korea

mycolabadmin

Researchers in Korea isolated and identified three types of fungi never before recorded in the country that live inside brown seaweed. These fungi were found in Sargassum species collected from Korean coastal areas and were identified using DNA analysis and microscopy. The discovery reveals that Korean seaweed harbors diverse fungal communities that may produce useful compounds for medicine and agriculture, highlighting the unexplored potential of marine ecosystems.

Characterization and Biological Characteristics of Alternaria, Botryosphaeria, Pestalotiopsis, and Trichothecium Species Associated with Postharvest Loquat Fruit Rot in Yunnan, China

mycolabadmin

Researchers in China identified four types of fungal pathogens responsible for loquat fruit rot after harvest. These fungi cause different symptoms ranging from ring-shaped spots to soft decay, with infection rates between 4-12%. The study confirmed each pathogen’s ability to cause disease and found that some are more aggressive than others. This research helps growers understand what causes loquat spoilage and suggests that careful handling and cool storage can reduce losses.

Disseminated Scedosporium boydii infection with pulmonary and cerebral involvement in a patient with COPD: A case report

mycolabadmin

A 51-year-old man with chronic lung disease developed a life-threatening brain infection caused by a rare fungus called Scedosporium boydii. The infection started in his lungs and spread to his brain, causing a fluid-filled abscess. Despite treatment with antifungal medications and surgery, the patient died because the initial treatment was incomplete and the infection had time to progress to his brain.

Genotypic and Phenotypic Investigation of Clinical Aspergillus isolates from Iran Indicates Nosocomial Transmission Events of Aspergillus flavus

mycolabadmin

Researchers studied fungal infections caused by Aspergillus species in Iranian hospitals from 2020 to 2023. They found that Aspergillus flavus was the most common cause of infection and discovered evidence of several hospital-related outbreaks through genetic analysis. All isolates tested were susceptible to current antifungal medications, but the discovery of hospital transmission suggests the need for better infection control measures like improved air filtration in hospitals.

Epidemiology of Candidemia, Candiduria and Emerging Candidozyma (Candida) auris Across Gulf Cooperative Council Countries and Yemen in the Arabian Peninsula

mycolabadmin

This comprehensive review examines fungal bloodstream and urinary tract infections caused by Candida species across Middle Eastern countries. The study shows that while Candida albicans remains common, dangerous antibiotic-resistant strains like Candidozyma auris are increasingly appearing in hospitals. The research highlights that better diagnostic tools and infection prevention practices are urgently needed in the region to protect patients and reduce deaths from these serious infections.

Geographical distribution of Cryptococcus neoformans in Iran, pathogenic factors, and antifungal susceptibility profile

mycolabadmin

Researchers tested pigeon droppings from across Iran to find a dangerous fungus called Cryptococcus neoformans that can cause serious lung infections. They found this fungus in about 8.6% of samples, with more present in some provinces than others. The fungus showed concerning resistance to some common antifungal medications but remained sensitive to others like voriconazole, which could help guide treatment decisions.

The refractory nailbed ulceration caused by Candida parapsilosis after nail extraction

mycolabadmin

An 82-year-old woman developed a stubborn wound on her toenail bed after having her nail surgically removed to treat an infection. When the wound did not heal for six months, doctors discovered it was caused by a fungus called Candida parapsilosis, which is normally found on skin but can cause infections when given the opportunity through wounds. After identifying the fungus, doctors treated her with an antifungal medication called fluconazole for three months, and her wound completely healed. This case shows the importance of testing chronic nail infections for their specific cause before performing surgery.

Implantation of Aspergillus Section Flavi in French Maize and Consequences on Aflatoxin Contamination of Maize at Harvest: Three-Year Survey

mycolabadmin

A harmful fungus called Aspergillus that produces cancer-causing toxins (aflatoxins) has become increasingly common in French maize crops over the past three years. Researchers collected and tested maize samples from across France and found that by 2020, about 80% of samples contained this fungus, and 16% had measurable levels of aflatoxins. This is happening because of hotter and drier conditions caused by climate change, which favor the fungus’s growth. The findings suggest that France needs to improve its monitoring and safety measures for maize to protect consumers and farmers.

First Report of Fusarium avenaceum Causing Blight on Juniperus formosana in China: Morphological and Molecular Characterization

mycolabadmin

Juniperus formosana is a beautiful ornamental plant used in landscaping. In October 2024, researchers discovered that a fungus called Fusarium avenaceum was causing a blight disease on these plants in Kaili City, China, making the needles turn yellow and wither. Through detailed examination of the fungus under a microscope and DNA testing, scientists confirmed this is the first time this particular fungus has been found causing this disease on Juniperus formosana in China.
