چکیده
Cultures of blood from a hemodialysis line repeatedly yielded a gram-positive rod. The organism was identified as Tsukamurella tyrosinosolvens by 16S ribosomal DNA sequencing, and the patient was treated successfully by removal of the line.

Tsukamurella spp. are a rare but important cause of intravascular catheter-related bacteremia in immunocompromised patients. The organism is an aerobic, Gram-positive, weakly acid-fast bacillus that is difficult to differentiate using standard laboratory methods from other aerobic actinomycetales such as Nocardia spp., Rhododoccus spp., Gordonia spp., and the rapid growing Mycobacterium spp. We...

INTRODUCTION We describe an immunocompromised patient with Tsukamurella tyrosinosolvens bacteremia and coinfection of Mycobacterium bovis pneumonia. CASE DESCRIPTION A 75-year-old male was admitted to our hospital complaining of persistent fever with general malaise. His medical history showed that he had diabetes mellitus (HbA1C 9.2%). A chest computed tomography (CT) showed left upper lung ...
متن کاملA Case Report of Tsukamurella pulmonis Infection Misidentified as Atypical Mycobacteria
We report a case of catheter-related bacteremia due to Tsukamurella pulmonis. T. pulmonis is a rare cause of opportunistic infection in immunosuppressed patients and in cases of indwelling foreign materials. This infection was nearly impossible to identify using conventional phenotyping methods because of its similarities to the related genera Nocardia, Rhodococcus, Gordonia, Streptomyces, Cory...

We describe a previously healthy patient with chronic otitis media complicated with cerebellar abscess caused by Tsukamurella tyrosinosolvens. The organism was identified based on conventional biochemical identification methods, PCR-restriction fragment length polymorphism analysis of the hsp65 gene, and 16S rRNA gene sequencing. The patient was treated successfully with debridements and prolon...

Owing to the highly similar phenotypic profiles, protein spectra and 16S rRNA gene sequences observed between three pairs of Tsukamurella species (Tsukamurella pulmonis/Tsukamurella spongiae, Tsukamurella tyrosinosolvens/Tsukamurella carboxy-divorans, and Tsukamurella pseudospumae/Tsukamurella sunchonensis), we hypothesize that and the six Tsukamurella species may have been misclassified and th...
