“…When material from erythrasma lesions was cultured on an agar medium containing 20% fetal calf serum in tissue culture medium 199 without phenol red or bicarbonate, the resulting colonies produced varying degrees of orange to coral-red fluorescence (182). Apparently only one colony type was characterized and sent to the National Collection of Type Cultures to become the type strain of C. minutissimum, NCTC 10288 (183).…”

Coryneform bacteria in infectious diseases: clinical and laboratory aspects

Coryneform isolates from clinical specimens frequently cannot be identified by either reference laboratories or research laboratories. Many of these organisms are skin flora that belong to a large number of taxonomic groups, only 40% of which are in the genus Corynebacterium. This review provides an update on clinical presentations, microbiological features, and pathogenic mechanisms of infections with nondiphtheria Corynebacterium species and other pleomorphic gram-positive rods. The early literature is also reviewed for a few coryneforms, especially those whose roles as pathogens are controversial. Recognition of newly emerging opportunistic coryneforms is dependent on sound identification schemes which cannot be developed until cell wall analyses and nucleic acid studies have defined the taxonomic groups and all of the reference strains within each taxon have been shown by molecular methods to be authentic members. Only then can reliable batteries of biochemical tests be selected for distinguishing each taxon.

“…Sarkany et al (1961) originally detected Gram-positive rods from lesions associated with erythrasma and named the bacterium C. minutissimum (Sarkany et al, 1962). Somerville (1973) classified aerobic cutaneous diphtheroids into 15 groups from the results of nine tests.…”

“…The disease tends to occur at intertriginous sites, and exhibits a coral-red fluorescence under Wood's light (Hay & Adriaans, 1998). Sarkany et al (1961) demonstrated the presence of Grampositive rods in the scales of erythrasma and named the causative organism Corynebacterium minutissimum (Sarkany et al, 1962). This bacterium is thought to produce excess coproporphyrins (Hay & Adriaans, 1998).…”

Erythrasma is a superficial skin disease caused by Gram-positive Corynebacterium species. Coral-red fluorescence under Wood's light, strongly suggestive of erythrasma, can be attributed to the presence of porphyrins. Fractionated porphyrin analysis in erythrasma lesions is yet to be reported. We attempted to investigate erythrasma lesions by isolating the responsible bacteria and determining their exogenous porphyrin production by HPLC analysis. We observed a 78-year-old woman with erythrasma who had a well-demarcated slightly scaling patch on her left foot, between the fourth and fifth toes. Two kinds of colonies on 5 % sheep blood agar were obtained from this lesion. Analysis of the 16S rRNA sequence revealed the colonies to be Corynebacterium aurimucosum and Microbacterium oxydans. HPLC analysis demonstrated that coproporphyrin III (Copro III) levels were clearly elevated, although the amounts of protoporphyrin were diminished. These results indicate that the fluorescent substance was Copro III. This study supports the view that excess Copro III synthesis by C. aurimucosum and M. oxydans leads to accumulation of porphyrin in cutaneous tissue, which emits a coral-red fluorescence when exposed to Wood's light.

“…The name "Corynehuc.tt.riirm minictissimitm" was proposed by Sarkany et al (8) for the causative agent of erythrasma in humans (7)(8)(9). However, this name was omitted from the Approved Lists of Bacterial Names (10) and therefore lost standing in bacterial nomenclature.…”
