Actinomadura madurae is an aerobic actinomycete which is best known worldwide as the cause of actinomycotic mycetomas. It has not previously been reported. Here, we utilized deep sequencing of 16S rRNA to implicate Actinomadura madurae as the cause of mycetoma in a diabetic patient when culture and. Proc Natl Acad Sci U S A Sep 29; Draft Genome Sequence of Actinomadura madurae LIID-AJ, Isolated from a Human Mycetoma Case. Vera-Cabrera L.
The case exemplifies several capabilities of deep sequencing as a clinical diagnostic tool, specifically, deconvoluting the identity of individual organisms within polymicrobial samples, classifying organisms directly from patient specimens without the need for culture, and characterizing nonviable or unculturable organisms in this case, organisms killed by FFPE processing prior to pathology examination.

It contains aerobic, Gram-positive, non-acid-fast, non-motile, chemo-organotrophic actinomycetes that produce well-developed, non-fragmenting vegetative mycelia and aerial hyphae that differentiate into surface-ornamented spore chains.

Here, we utilized deep sequencing of 16S rRNA to implicate Actinomadura madurae as the cause actimomadura mycetoma in a diabetic patient when culture and conventional molecular methods were overwhelmed by overgrowth of other organisms. This finding is consistent with the results of both culture and Sanger sequencing for the specimen, which were dominated by S.
A punch biopsy specimen of the lesion was submitted to pathology, revealing marked acute and chronic inflammation and an inclusion of abundant actknomadura structures consistent with aerobic actinomycetes Fig. Approximately 4 years prior to the current presentation, the diagnosis of actinomycotic mycetoma was adtinomadura established by histology, and she was initiated on antibiotic therapy with penicillin mg orally [p.

The patient was referred to the Madufae Disease clinic at Harborview Medical Center for further evaluation. A number of other organisms were also detected, reflecting the polymicrobial nature of such specimens 5. A portion of the specimen was concurrently submitted for culture in order to establish the identity of the aerobic actinomycetes-like nadurae and to evaluate its antibiotic sensitivities; however, the culture quickly became overgrown by Staphylococcus aureuspreventing culture for slower-growing aerobic actinomycetes species.
