Tsukamurella tyrosinosolvens - An unusual case report of bacteremic pneumonia after lung transplantation

Abstract

BackgroundLung transplant recipients have an increased risk for actinomycetales infection secondary to immunosuppressive regimen.Case presentationA case of pulmonary infection with bacteremia due to Tsukamurella tyrosinosolvens in a 54-year old man who underwent a double lung transplantation four years previously is presented.ConclusionThe identification by conventional biochemical assays was unsuccessful and hsp gene sequencing was used to identify Tsukamurella tyrosinosolvens.

SupplementingPropionibacterium acidipropioniciP169 does not affect methane production or volatile fatty acid profiles of different diets inin vitrorumen cultures from heifers

“…The primer sequences of P169 were generated based on suppression hybridization approach, which identified gene sequence unique to P169 (Peng et al, 2011). In addition, a 16S universal primer set (Ménard et al, 2009) and a propionibacteria genus specific primer set were used to amplify specific regions of 16S rDNA (Rossi et al, 1999). Primer set sequences, annealing temperatures and product sizes are shown in Table II.…”

Mycobacteria and Other Acid Fast Organisms Associated With Pulmonary Disease in Jos, Nigeria Pulmonary Disease and Acid Fast Organisms

“…2,[23][24] Nocardi spp and Tsukamurella spp have also been associated with pulmonary disease in humans. 8,[25][26] There are scare reports associating M. duvalli with human infection although it has been reported to have some antigenic relatedness with M. leprae 27 and also was reported in HIV patient in India. 28 All three genera (Mycobacteria, Nocardia, Tsukamurella) belong to the same Family Actinomycetales with mycolic acid cell walls.…”

Tsukamurella tyrosinosolvens and Rhizobium radiobacter sepsis presenting with septic pulmonary emboli

“…Systemic T. tyrosinosolvens infections were first reported in patients with cardiac pacemaker implants [7]. Since then, T. tyrosinosolvens has been implicated in three cases of catheter‐related bacteraemia, two ophthalmological infections, one case of bacteraemic pneumonia, and one brain abscess [8–14]. The true frequency of Tsukamurella infections may be higher.…”
