Abstract
IntroductionWe describe an immunocompromised patient with Tsukamurella tyrosinosolvens bacteremia and coinfection of Mycobacterium bovis pneumonia.Case DescriptionA 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 consolidation . Two sets of blood culture at admission finally showed Tsukamurella tyrosinosolvens. Moreover, three transbronchoscopy washing specimen cultures revealed Mycobacterium bovis.Discussion and EvaluationThe organism Tsukamurella tyrosinosolvens was identified using conventional biochemical identification methods, PCR-restriction DNA fragment analysis, and 16S rRNA gene sequencing. The clinical mycobacterial isolates were identified to the species level by combining Polymerase Chain Reaction (PCR) with an oligonucleotide microarray to detect the M. bovis amplicons.ConclusionAccording to our literature review, our patient’s case was the first of a coinfection with Tsukamurella tyrosinosolvens and Mycobacterium bovis. Prolonged antibiotic treatment and underlying disease control are necessary for this type of patient.
