Although the patient remained ambulatory throughout the course of her disease, she gradually had to modify her footwear to accommodate the increasing size of her foot, which at the time of presentation was causing her great pain. For some sequences, multiple organisms met the identity threshold for species-level classification; in such cases, species names separated by a slash and genus names separated by a semicolon list the possible taxonomic assignments.

Table 1 details the classification of deep-sequencing reads from the specimen submitted for analysis. Consistent with culture results, reads classified as S. The isolate from the patient’s blood was subjected to dilutional antimicrobial susceptibility tests with 12 antimicrobial agents and was found to have a wide spectrum of susceptibility. A portion of the specimen was concurrently submitted for culture in order to establish the identity of the aerobic actinomycetes-like organism and to evaluate its antibiotic sensitivities; however, the culture quickly became overgrown by Staphylococcus aureuspreventing culture for slower-growing aerobic actinomycetes madrae.

Given the extent of infection, neither additional antibiotic therapy nor debridement with subsequent reconstruction was felt to be a viable option, and a recommendation was made for below-the-knee amputation.

National Center for Biotechnology InformationU. Further, it should be noted that read counts in 16S rRNA amplicon deep-sequencing studies are semiquantitative and correlate only roughly with the relative abundances of organisms due to bias introduced through PCR 23maduuraediffering DNA extraction efficiencies for particular organisms 25and organism-specific differences in 16S rRNA operon counts A number of other organisms were also detected, reflecting the polymicrobial nature of such specimens 5.

In one small, prospective study, initial treatment with intravenous gentamicin, intravenous penicillin, and oral sulfamethoxazole-trimethoprim followed by oral sulfamethoxazole-trimethoprim and oral amoxicillin maintenance was found effective in empirically treating disease minimally involving the bones, while actinomaudra incorporating intravenous amikacin and oral sulfamethoxazole-trimethoprim for initial treatment and oral sulfamethoxazole-trimethoprim for maintenance therapy were useful in cases of more extensive bony involvement
