Abstract
Thirty-two isolates of Cryptococcus neoformans from patients and one from the wild obtained in Japan were characterized for their serotype, self-fertility, and mating behaviour by crossing them with two mating types of Filobasidiella neoformans var. neoformans and F. neoformans var. bacillispora. Of the 32 isolates from patients, 31 were of serotype A and the remaining one was of serotype D. Although these 32 isolates were all self-sterile, 23 serotype A and one serotype D isolates produced a complete sexual state when mixed with the a mating type of F. neoformans var. neoformans. The one natural isolate was of serotype A-D and self-fertile. The Japanese clinical isolates of C. neoformans appear to be predominantly serotype A and α mating type of F. neoformans var. neoformans as is the case in the U.S.A. Trente-deux souches de Cryptococcus neoformans isolées de malades et une de la nature au Japon sont étudiées pour leur sérotype, leur fertilité propre et leur comptabilité après confrontation avec deux types sexués de Filobasidiella neoformans var. neoformans et F. neoformans var. bacillispora. Des 32 souches de malades, 31 sont de sérotype A et la dernière de sérotype D. Quoique ces 32 souches soient toutes stériles par elles-mêmes, 23 du sérotype A et une du sérotype D produisent une forme sexuée complète quand elles sont confrontées au type sexué a de F. neoformans var. neoformans. La souche provenant de la nature est de sérotype A-D et possède une fertilité propre. Les souches japonaises de C. neoformans semblent être essentiellement de sérotype A et de type sexué α de F. neoformans var. neoformans comme c'est le cas aux Etats-Unis.Keywords
