Project description:Candida tropicalis is a leading cause of invasive candidiasis in the Asia-Pacific region with reported crude mortality rates exceeding 50%. The rising prevalence of azole-resistant strains presents a significant clinical challenge. We analyzed 1,016 C. tropicalis clinical isolates collected over nine years from 27 hospitals across North India. Fluconazole resistance was detected in 5.1% (n = 52) of isolates, with cross-resistance observed to voriconazole in 55.7% and itraconazole in 44.2% of isolates. Multilocus sequence typing (MLST) analysis of global 1,630 isolates including 208 Indian and whole-genome sequencing of 716 global isolates (139 Indian) confirmed the clonal emergence and persistence of azole-resistant MLST clade 4 strains in Indian hospitals. Phylogenomic analyses identified that Indian azole-resistant lineage was closely related to azole-resistant isolates from mainland China and Taiwan. The underlying mechanism of resistance involved hotspot mutations (Y132F) in the ERG11 gene along with its duplication, overexpression, and twofold high ergosterol content. Comparative transcriptomics of two clinical isolates exhibiting >512 fold difference in fluconazole susceptibility identified upregulation of virulence-associated genes, ALS7 gene (eightfold), SAP7 and SAP9 (1.6- and 2-fold, respectively) in azole-resistant isolate. Furthermore, azole-resistant isolates showed robust biofilm-associated metabolic activity (twofold), reduced β-glucan exposure, and greater survival in both neutrophil and macrophage killing assays. Notably, azole-resistant lineage exhibits several traits associated with adhesion and immune evasion that could possibly enable its spread in healthcare settings and signals the beginning of a greater spread of this clone. The urgent need for continuous genomic surveillance and antifungal stewardship is warranted to mitigate the spread of multidrug-resistant C. tropicalis.
Project description:Transcriptional profiling of mycobacterium tuberculosis clinical isolates in China comparing extensively drug-resistant tuberculosis with drug sensitive one. The same condition experiment. The samples were from the different drug-resistant strains. Only one replicate.
Project description:Staphylococcus aureus clonal complex 398 (CC398) isolates colonize livestock and can spread to human contacts. Genetic analysis of isolates epidemiologically associated with human-to-human, but not livestock, transmission in multiple countries and continents identified a common clade that was negative for tet(M) and positive for bacteriophage 3. Another group of human-to-human-transmitted isolates belonged to the common livestock-associated clade but had acquired a unique φ7 bacteriophage.
