Disease: Disseminated fungal infection

The impact of osteoarticular invasion by Coccidioides Sp disseminated infection

mycolabadmin

A 48-year-old man from Mexico developed a serious fungal infection caused by Coccidioides, which spread from his lungs to his skin, bones, and joints, causing pain and swelling. Despite having a normally functioning immune system, he developed progressive disease that was initially misdiagnosed as rheumatoid arthritis. After switching to the antifungal medication fluconazole, his condition improved dramatically, with symptoms resolving within several months of treatment.

Efficacy assessments of SF001, a next-generation polyene antifungal, in a neutropenic mouse model of invasive fusariosis

mycolabadmin

This study tested a new antifungal drug called SF001 against a serious infection called fusariosis in mice. SF001 performed as well as the current standard treatment (amphotericin B) but with better safety profiles. The drug successfully reduced fungal infections in organs and improved survival rates in infected mice without showing signs of toxicity at higher doses.

Disseminated Lichtheimia ramosa infection in a Japanese Black calf

mycolabadmin

A young cow developed a severe fungal infection caused by Lichtheimia ramosa, a rare type of mold. The infection spread throughout the cow’s body, affecting the liver and digestive system. The cow had an underdeveloped immune system (thymus hypoplasia) and was given multiple antibiotics for weeks, which actually made the fungal infection worse by killing normal protective bacteria. Despite various treatments, the cow’s condition worsened and it had to be euthanized.

Dectin-1 and dectin-2 drive protection against Sporothrix brasiliensis in experimental sporotrichosis

Scientists studied how the body’s immune system defends against Sporothrix brasiliensis, a dangerous fungus spreading through Latin America. They found that two immune receptors called dectin-1 and dectin-2 are crucial for fighting this infection by activating killer T cells and controlling regulatory T cells. Surprisingly, a cytokine called IL-17, commonly associated with fungal defense, actually helps maintain tissue integrity rather than directly killing the fungus.

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.

Disseminated Lichtheimia ramosa infection in a Japanese Black calf

mycolabadmin

A young calf developed a serious fungal infection caused by Lichtheimia ramosa despite treatment with multiple antibiotics. The calf had an underdeveloped thymus gland, making it vulnerable to infections. The fungus spread throughout the calf’s body, affecting the liver and digestive system. This case highlights how prolonged antibiotic use and weakened immunity can allow dangerous fungi to flourish.
