Genetic mutations in Cryptococcus neoformans pyrimidine salvage pathway enzymes contribute to reduced susceptibility against 5-fluorocytosine

Abstract excerpt

Cryptococcal meningitis is a high-mortality infection. Adding 5-fluorocytosine (5-FC) to its treatment improves outcomes, but resistance to 5-FC presents a significant challenge. We conducted whole-genome sequencing on seven C. neoformans isolates with varying 5-FC susceptibility, along with proteomic and in silico analyses. Our findings indicate that mutations in genes of the pyrimidine salvage pathway are...
