[Eumycotic mycetomas in horses caused by Curvularia verruculosa].

The researchers found a type of fungus known as Curvularia verruculosa, which can cause a horse to develop granulomatous lesions, or eumycotic mycetomas, in Argentina. This is the first observation of this fungus in the country’s horse population.

Identification of the Fungus

• Curvularia verruculosa was identified as the fungi responsible for causing eumycotic mycetomas in horses. Eumycotic mycetomas are characterised by granulomatous lesions typically forming on the legs of horses.
• The fungus was isolated from the skin of these animals, giving a more direct insight into the pathogenic nature of this mycosis.

The Methodology

• To isolate the fungus, the researchers cultured the lesions of the infected horse’s skin on Sabouraud dextrose agar medium. This is a common type of agar used specifically for the cultivation of dermatophytes and other types of fungi.
• The growing of the fungus in a controlled environment allows for a more detailed analysis of its characteristics and behaviour.

Geographical Distribution

• The horses that were infected with the Curvularia verruculosa fungus were located in the suburb Comandante Fontana, in Formosa, Argentina.
• This made it the first scientifically documented case of Curvularia affecting horses in Argentina, expanding our knowledge of the geographical reach of this fungus.

Significance of Findings

• The findings of this research will have an impact on equine health management in Argentina, and potentially other regions where this fungus may exist.
• Such knowledge can assist in the development of preventative measures and treatments for horses affected by this disease.
• Furthermore, the identification of new disease vectors in domesticated animals can alert public health officials to potential risks in human populations, given the shared environment and close interactions between humans and horses.
