What Do We Know About Cryptococcus spp. in Portugal? One Health Systematic Review in a Comprehensive 13-Year Retrospective Study (2013–2025)

mycolabadmin

This study examines cryptococcosis, a fungal infection that affects both animals and humans, across Portugal from 2013-2025. Researchers found that about 4.5% of animal samples tested positive for Cryptococcus species, with infections most common in dogs and cats. The infections peaked during summer months and were most prevalent in central Portugal, with different fungal species affecting different animal types. The research emphasizes the importance of coordinated monitoring across animals, humans, and the environment to better understand and control this disease.

First occurrence of feline sporotrichosis in a metropolitan area of Central-West Brazil

mycolabadmin

Researchers in Brazil discovered the first case of a serious fungal infection called sporotrichosis in a domestic cat in the Goiania metropolitan area. The infection was caused by a fungus called Sporothrix brasiliensis, which can spread from cats to humans through scratches and bites. This finding is important because it shows the disease is spreading to new regions of Brazil that previously didn’t have confirmed cases, and suggests residents need to be cautious around stray cats.

Stonebrood Disease—Histomorphological Changes in Honey Bee Larvae (Apis mellifera) Experimentally Infected with Aspergillus flavus

mycolabadmin

Stonebrood is a rare fungal disease of honey bees caused by Aspergillus flavus that can kill bee larvae very quickly. Researchers experimentally infected bee larvae with the fungus and tracked how the disease progressed, finding that larvae died within 48 hours of infection. The study revealed that the fungus likely kills bees by producing toxins rather than by physical damage, and poses a health risk to beekeepers who inhale the fungal spores.

Prospective Case–Control Study of Determinants for African Swine Fever Introduction in Commercial Pig Farms in Poland, Romania, and Lithuania

mycolabadmin

This study examined how African swine fever gets introduced into commercial pig farms in Poland, Romania, and Lithuania. Researchers found that farms closer to other infected farms, farms growing crops that attract wild boar, and farms with inadequate biosecurity measures were more likely to have outbreaks. Simple protective measures like proper carcass disposal and installing insect screens on doors and windows significantly reduced disease risk.

Sporothrix davidellisii: A new pathogenic species belonging to the Sporothrix pallida complex

mycolabadmin

Scientists have identified a new fungal species called Sporothrix davidellisii that causes an infection in cats. This fungus was found in an infected cat in Australia and is related to other fungi that cause sporotrichosis, a skin disease in humans and animals. The discovery shows that cats can help scientists identify new fungal pathogens in their environments, making them important sentinels for tracking emerging diseases.
