 AB    Karyotyping of Cryptococcus neoformans var. neoformans can be used as an
       epidemiological tool for C. neoformans infections. In this study of over
       40 isolates from both clinical and environmental sources, 90% had a
       unique chromosome banding by pulsed-field electrophoresis. There was no
       conserved pattern associated with body site of infection, geographical
       location of the isolate, or human immunodeficiency virus status.
       Karyotypes of individual isolates remained stable during both in vitro
       passage and in vivo infections. Karyotype was used to exclude the
       possibility of nosocomial spread of C. neoformans in one clinical
       situation and supported relapse in two other cases. Because of its
       variable sizes between isolates, karyotyping of C. neoformans is a
       convenient method for molecular identification of different strains.
