Objective  To understand the genotype distribution of clinical Cryptococcus neoformans var. grubii strains from China and Brazil using multilocus microsatellite typing (MLMT) method and to study the difference in their MLMT genotyping.   Methods  DNA was extracted from the identified 69 clinical Cryptococcus neoformans var. grubii strains. DNA fragments covering microsatellite loci (CNG1

CNG2

and CNG3) were amplified by PCR and sequenced. The number of each motif repeats in 3 microsatellite regions (“TA”

“GA”

and “CAT” repeats for CNG1

CNG2

and CNG3

respectively) was calculated. The MLMT types of 69 clinical Cryptococcus neoformans var. grubii strains were determined according to the repeat number of different motifs. Data were analyzed using SPSS 11.5 software.   Results  Five genotypes were identified in 33 clinical strains from China. Of these strains

29 were MLMT-17

accounting for 87.88% of the total strains. Ten genotypes were identified in 36 clinical strains from Brazil. Of the 36 strains

19 were MLMT-13

accounting for 52.78% of the total strains.   Conclusion  The difference is great in major genotype distributions of the clinical Cryptococcus neoformans var. grubii strains from China and Brazil. The genotype of clinical strains from Brazil is diversely distributed.
