Sporothrix globosa, reported from the USA, Europe, and Asia, is a recently described pathogenic species morphologically similar to Sporothrix schenckii. In this study, the phylogenetic affinities of 32 clinical and environmental isolates morphologically identified as S. schenckii, from Mexico, Guatemala, and Colombia, were assessed by cladistic analysis of partial sequences of the calmodulin gene using the maximum parsimony and neighbor-joining methods. The study revealed that one out of 25 isolates from Mexico (4%), one out of three isolates from Guatemala (33.3%), and two out of four isolates from Colombia (50%) belonged to S. globosa, while the other isolates belonged to S. schenckii sensu stricto. This is the first record of S. globosa from Mexico, and Central and South America.
球形孢子丝菌，已在美国、欧洲和亚洲被报道，是一种最近描述的致病物种，在形态上与申克孢子丝菌相似。在本研究中，通过使用最大简约法和邻接法对钙调蛋白基因的部分序列进行分支分析，评估了从墨西哥、危地马拉和哥伦比亚形态学上鉴定为申克孢子丝菌的32株临床和环境分离株的系统发育亲缘关系。研究发现，来自墨西哥的25株分离株中有1株（4%）、来自危地马拉的3株分离株中有1株（33.3%）以及来自哥伦比亚的4株分离株中有2株（50%）属于球形孢子丝菌，而其他分离株属于狭义的申克孢子丝菌。这是墨西哥以及中美洲和南美洲关于球形孢子丝菌的首次记录。
