“…However, in 1938, Jones & Martin [18] recovered from clinical specimens atypical C. albicans strains with unusual physiological characteristics even before C. dubliniensis was described. In their studies on the vaginal flora, these authors isolated yeast strains that did not utilise sucrose as a carbon source, formed few chlamydospores on corn meal agar and were non‐pathogenic in rabbits.…”

“…15 To date, although several phenotypic methods have been described to distinguish C. albicans from C. dubliniensis, the identification of the latter species still requires genotypic assays. 16,17 However, in 1938, Jones & Martin [18] recovered from clinical specimens atypical C. albicans strains with unusual physiological characteristics even before C. dubliniensis was described.

Candida africana is a recently described opportunistic yeast pathogen that has been linked to vaginal candidiasis. This yeast was first described, in 1995, as atypical chlamydospore-negative Candida albicans strain, and subsequently proposed as a new Candida species on the basis of morphological, biochemical and physiological characteristics clearly different from those of typical C. albicans isolates. Phylogenetic studies based on the comparison of ribosomal DNA sequences demonstrated that C. africana and C. albicans isolates are too closely related to draw any conclusions regarding the status of a new species. Therefore, on the basis of these studies, some authors considered C. africana as a biovar of C. albicans even if genetic differences may be found if additional regions of genomic DNA are sequenced. The taxonomic situation of C. africana and its phylogenetic relationship with other Candida species is still controversial and remains, at present, a matter of debate. Our goal is to review the current knowledge about C. africana and highlight the development of rapid and accurate tests for its discrimination from C. albicans, Candida dubliniensis and Candida stellatoidea. Furthermore, through the analysis of literature data, we have found that C. africana has a worldwide distribution and a considerable number of features making its study particularly interesting.

“…Deep colonies of Candida stellatoidea, when plated in this manner, had the typical stellate appearance (Jones and Martin, 1938) and a green discoloration of the agar around the colonies appeared in 6 to 7 days. Deep colonies of freshly isolated strains of Candida albicans were round and lacked the characteristic pigment formation of Candida stellatoidea.…”
