NR-48768??Cryptococcus neoformans, KN99a(Fungi)|Cryptococcus neoformans|KN99a|-130°C or colder|J HeitmanAcknowledgment for publications should read "The following reagent was obtained through BEI Resources, NIAID, NIH: Cryptococcus neoformans, Strain KN99a, NR-48768."|Quantity limit per order for this item is 1. This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment.
Cryptococcus neoformans (C. neoformans), strain KN99a was derived from strain H99O (BEI Resources NR-48767), after passage in the rabbit model of central nervous system infection. C. neoformans, strain H99 was isolated from the cerebrospinal fluid of a human male who had been treated for Hodgkin's disease in North Carolina, USA on February 14, 1978. After an unknown number of passages, strain H99 was reported to lose virulence and was subsequently passaged through the rabbit model of infection to increase its virulence. It was renamed as H99O and frozen in 1994.
C. neoformans var. grubii, strain H99O (H99) was sequenced in 2014 through a collaboration between Duke University and the Broad Institute (NCBI BioProject: PRJNA411). Strain H99O is the progenitor of nine phenotypic variants that display either increased or decreased mating ability, melanization and virulence.
C. neoformans, strain KN99a was derived from strain H99O concurrently with the congenic strain KN99α (BEI Resources NR-48769). The congenic pair was created by backcrossing strain H99O with strain H99F (BEI Resources NR-48770).
Each vial contains approximately 0.5 mL of C. neoformans in 20% glycerol.
