Project description:The aims of this study were to present modifications to the annotations of the genome of C. posadasii, one of two closely related species of Coccidioides, a dimorphic fungal pathogen that causes coccidioidomycosis, also called Valley Fever. Proteins present in lysates and filtrates of in vitro grown mycelia and parasitic phase spherules from C. posadasii strain Silveira were analyzed using a GeLC-MS/MS method.

Project description:Coccidioidomycosis, or Valley Fever, is a lung disease caused by inhaling Coccidioides fungi, prevalent in the Southwestern U.S., Mexico, and parts of Central and South America. Climate change is contributing to the spread of this disease. Many cases are asymptomatic, some are often misdiagnosed, and a small subset can progress to severe illness. To better understand lung responses during Coccidioides infection, we used single-cell RNA sequencing (scRNA-seq). We analyzed non-infected lungs (D0) and infected lungs at 5, 9, and 14 days post-infection (D5, D9, D14).

Project description:The CPS1 gene was identified as a virulence factor in the maize pathogen, Cochliobolus heterostrophus. Hypothesizing that the homologous gene in Coccidioides posadasii (Cp) could be important for virulence, we created a deletion mutant, Îcps1, which was unable to cause disease in three strains of mice (C57BL/6, BALB/c, or the severely immunodeficient NOD-scid,γcnull [NSG]). Only a single colony was recovered from one of 60 C57BL/6 mice following intranasal infections of up to 4400 spores. Following administration of very high doses (10,000 to 2.5 x 10^7 spores) to NSG and BALB/c mice, spherules were observed in lung sections at time points from day 3 to day 10 post-infection, but nearly all appeared degraded with infrequent endosporulation. Although the role of CPS1 in virulence is not understood, phenotypic alterations and transcription differences of at least 33 genes in Îcps1 vs. Cp is consistent with both metabolic and regulatory functions for the gene. The in vitro phenotype of Îcps1 showed slower growth of mycelia with delayed and lower spore production compared to Cp, and in vitro spherules were smaller. Vaccination of C57BL/6 or BALB/c mice with live Îcps1 spores either intranasally, intraperitoneally or subcutaneously resulted in over 95% survival with mean residual lung fungal burdens <1000 colony-forming units from an otherwise lethal Cp intranasal infection. Considering its apparently complete attenuation of virulence and the high degree of resistance to Cp infection when used as a vaccine, Îcps1 is a promising vaccine candidate for preventing coccidioidomycosis in humans or other animals. Wild type and CPS1 deletion mutant strains of Coccidioides posadasii strain Silveira spherules grown for 48 hours in Converse medium at 38 degrees celsius in duplicate. RNAseq was performed on an Illumina HiSeq2000 (2x100 paired end).
