Abstract:
Mycotic sepsis may be caused by obligately and facultatively pathogenic fungi. Obligately pathogenic fungi with dimorphism causing septic forms of cryptococcosis, blastomycoses, sporotrichosis, histoplasmosis, and coccidioidosis produce suppurative-necrotic lesions in the internal organs and the central nervous system. They run a course of primary diseases but occur rarely in our latitudes. More frequently, the septic forms of mycoses are due to conditionally pathogenic fungi (Candida, Aspergilli) and are manifested as a secondarily induced disease under conditions of various forms of immune deficiency of the host. Therefore, the main attention is paid to the discussion of protective reactions, particularly phagocytosis, since the latter has killer mechanisms against fungi. The presented data on the fungicidal system and detailed analysis of the functional properties of macrophages and leukocytes are important for the elucidation of the possibility of accumulation and transfer of medicinal biological substances directed at the elimination of the fungi.
Insights
Mycotic sepsis, often caused by opportunistic fungi like Candida, arises in immune-deficient individuals. Understanding immune cell functions like phagocytosis is key to developing treatments that eliminate fungal infections.
Area of Science:
- Medical Mycology
- Immunology
Context:
- Mycotic sepsis can stem from both obligate and facultative fungal pathogens.
- Obligate pathogens cause primary diseases like cryptococcosis, while facultative pathogens, such as Candida and Aspergilli, frequently cause secondary infections in immunocompromised hosts.
Purpose:
- To discuss the protective immune responses against fungal infections, focusing on phagocytosis.
- To analyze the fungicidal mechanisms of macrophages and leukocytes.
Summary:
- Fungal infections leading to sepsis are caused by various fungi, with opportunistic pathogens being more common in clinical settings.
- The study emphasizes the critical role of phagocytic cells, including macrophages and leukocytes, in combating fungal infections.
- Investigating the functional properties of these immune cells is crucial for developing targeted antifungal therapies.
Impact:
- Provides insights into the host-pathogen interactions in mycotic sepsis.
- Highlights the importance of immune cell function in antifungal defense.
- Informs the development of novel therapeutic strategies for fungal infections by focusing on enhancing immune cell activity and drug delivery.
