Annellated conidiogenous cells in Petriellidium boydii (Scedosporium apiospermum)
Sabouraudia
|December 1, 1980
Abstract:
Annellated conidiogenous cells of both the mononematous (Scedosporium state) and synnematous (Graphium state) conidiophores develop in the conidial state of Petriellidium (= Allescheria) boydii, Scedosporium (= Monosporium) apiospermum. Conidiogenesis in this species is characterized by percurrent proliferation of the conidiogenous cells and the conidia are holoblastic and annellidic.
Insights
Petriellidium boydii and Scedosporium apiospermum exhibit annellated conidiogenous cells in their conidial states. These fungi display holoblastic and annellidic conidiogenesis, characterized by percurrent proliferation.
Area of Science:
- Mycology
- Fungal Morphology
- Plant Pathology
Background:
- Petriellidium boydii and Scedosporium apiospermum are clinically significant fungi.
- Understanding their conidiogenesis is crucial for accurate identification and disease management.
Purpose of the Study:
- To characterize the conidiogenesis in Petriellidium boydii and Scedosporium apiospermum.
- To describe the morphology of conidiogenous cells and conidia.
Main Methods:
- Microscopic examination of conidiophores and conidia.
- Analysis of conidiogenous cell proliferation patterns.
Main Results:
- Annellated conidiogenous cells were observed in both mononematous (Scedosporium state) and synnematous (Graphium state) conidiophores.
- Conidiogenesis is characterized by percurrent proliferation.
- Conidia were identified as holoblastic and annellidic.
Conclusions:
- The study confirms the presence of annellated conidiogenous cells in these fungal species.
- The findings provide detailed insights into the conidiogenesis of Petriellidium boydii and Scedosporium apiospermum.
