What is solitary solid nodule?
The pathogenicity of fungi can be divided into exogenous or endogenous infection, allergy, toxin poisoning or tumorigenesis. Fungi can cause different diseases of various animals through different forms. Some fungi have parasitic pathogenicity, some have conditional pathogenicity, and some produce toxins to poison animals.
Among them, pathogenic fungal infections, mainly some exogenous fungal infections, can cause skin, subcutaneous and systemic infections. Because dermatophytes are hornophilic, they can cause local inflammation and pathological changes through mechanical stimulation and metabolites.
Deep infection of fungi by phagocytes phagocytosis, not killed and can cause chronic granuloma inflammation and tissue necrosis ulcer formation. Conditional pathogenic fungal infection, some endogenous fungi such as Candida, Aspergillus, Trichoderma, etc., are not highly pathogenic, only after the body's immunity is reduced or long-term application of antibiotics and hormones, can cause infection. Fungal allergic diseases, some fungi can cause allergic reaction positive, but not pathogenic.
matters needing attention
