Pneumocystis

Pneumocystis leverages Oxford Nanopore Technologies MinION real-time long-read sequencing to detect and characterize Pneumocystis jirovecii and other mycobiome members directly from bronchoalveolar lavage (BAL) and induced sputum (IS) clinical specimens without prior culturing.

Key Features:

• Long-Read Sequencing: Employs Oxford Nanopore MinION real-time long-read sequencing to generate genome-wide data from lengthy DNA fragments.
• Unbiased Shotgun Sequencing: Uses unbiased shotgun sequencing to detect P. jirovecii and other fungal taxa within clinical samples.
• Direct Clinical Detection: Detects and characterizes P. jirovecii directly from respiratory specimens such as BAL and IS without in vitro culture.
• Mycobiome Profiling: Identifies pathogenic fungi (Aspergillus, Cryptococcus) and commensals (Candida, Malassezia) as components of the mycobiome.
• Clinical Diagnostic Application: Supports diagnosis of Pneumocystis pneumonia (PCP) and complements microscopic examination and real-time quantitative PCR (qPCR) approaches.
• Optimized Sample Preparation: Incorporates optimized sample preparation conditions to improve data quality for MinION long-read sequencing.
• Curated Databases and Analysis Tools: Integrates curated reference databases and specialized data analysis tools tailored to long-read MinION sequencing data.

Scientific Applications:

• Fungal Diagnostics: Enables detection and genomic characterization of P. jirovecii and other fungal pathogens in clinical metagenomic samples.
• Mycobiome Characterization: Facilitates comprehensive profiling of respiratory mycobiome composition and diversity in patient specimens.
• Research on Pathogenesis: Provides genomic data to support studies of fungal pathogenesis and host–fungus interactions in respiratory disease.
