Abstract:
Among patients of an allergological center there appeared cases of respiratory and cutaneous allergy provoked by fungal infection Paecilomyces varioti Bainier. In the soil the fungi occurred in the mycelial form while in humans and animals the infection manifested in a parasitic hemotropic-tissue form. Pathogenesis of the disease is related to chronic sepsis-like state produced by the persistence of parasitizing hemotropic-tissue Chlamydiaceae-like fungi in blood and tissue cells, sensitization to them, impairments of small and medium size vessels by immunocomplex type, and delayed hypersensitivity in tissues.
Insights
Respiratory and skin allergies in patients were linked to the fungal infection Paecilomyces varioti. This fungus, found in soil, causes a parasitic infection in humans and animals, leading to allergic reactions.
Area of Science:
- Mycology
- Immunology
- Allergology
Background:
- Paecilomyces varioti is a fungus.
- Fungal infections can cause allergic reactions.
Observation:
- Cases of respiratory and cutaneous allergy were observed in patients at an allergological center.
- The allergy was provoked by the fungal infection Paecilomyces varioti Bainier.
Findings:
- In soil, Paecilomyces varioti exists in a mycelial form.
- In humans and animals, the infection presents as a parasitic hemotropic-tissue form.
- Disease pathogenesis involves chronic sepsis-like state due to persistent hemotropic-tissue fungi, sensitization, immunocomplex-mediated vascular damage, and delayed hypersensitivity.
Implications:
- Highlights Paecilomyces varioti as a potential allergen.
- Suggests a novel pathogenic mechanism for fungal-induced allergies.
- Underscores the importance of identifying fungal sources in allergic disease diagnosis.
