Dermatophytosis in a Chilean fox: first case of Nannizzia gypsea in Lycalopex griseus and the need for a one health approach

mycolabadmin

A young wild Chilean fox was found with a skin infection caused by a fungus called Nannizzia gypsea, which lives in soil and can infect animals and humans. This is the first time this fungus has been documented in foxes anywhere. Doctors treated the fox with an antifungal cream and it recovered completely. The case highlights how increasing urbanization and contact between domestic pets, wild animals, and humans can spread fungal diseases, emphasizing the need for a coordinated public health approach.

A wild South American grey fox found near Santiago, Chile was treated for a skin infection caused by a fungus called Nannizzia gypsea. This is the first time this particular fungus has been documented in foxes, raising concerns about how increasing contact between domestic animals, wildlife, and humans due to urbanization may spread fungal diseases. The fox was successfully treated with topical antifungal cream, and the fungus was found to be susceptible to all tested antifungal medications.

Feline Cryptococcosis due to Cryptococcus gattii VGII (Recently Renamed as C. deuterogattii) in an FIV-Positive Cat With Demodicosis From Manaus, Central Amazon, Brazil

mycolabadmin

A 20-month-old cat from Brazil’s Amazon region presented with nasal discharge, skin lesions, and a neck mass and was diagnosed with cryptococcosis caused by a dangerous fungus called C. deuterogattii. The cat was also infected with feline immunodeficiency virus (FIV), which weakened its immune system and made it vulnerable to the fungal infection. Treatment with the antifungal medication fluconazole successfully cured the infection within 8 weeks, and the cat made a full recovery.

Antifungal susceptibility testing of Microsporum canis isolated from the skin of dermatologically healthy cats

mycolabadmin

Researchers tested healthy cats in Chile and found that about 5% carried a fungus called Microsporum canis that can cause ringworm. This fungus was resistant to a common antifungal drug called fluconazole. Indoor cats were more likely to carry the fungus than outdoor cats. Because cats can spread this fungus to people, identifying carrier cats is important for preventing human infections.

Usefulness of combining computed tomography and air sac fluid examination to rule out aspergillosis: case study in two gentoo penguins (Pygoscelis papua) with respiratory clinical signs

mycolabadmin

Two penguins at an aquarium showed respiratory problems and were suspected of having a serious fungal infection called aspergillosis. Doctors used CT scans to identify fluid in their air sacs and collected samples for testing. The tests showed the penguins did not have the fungal infection, so they did not need antifungal medications. Both penguins recovered naturally, demonstrating that combining imaging with fluid analysis can help identify the real cause of respiratory problems and avoid unnecessary medication.
