Pulmonary disease caused by Mycobacterium marseillense, Italy

Mycobacteriummarseillense was recently described as a new species belonging to the Mycobacterium avium complex (MAC).We describe a case of pulmonary disease caused by M. marseillense in an immunocompetent patient. All strains isolated from the patient were preliminarily identified as M. intracellulare; however, a retrospective molecular analysis corrected the identification to M. marseillense

Evaluation of a rapid immunochromatographic assay for the detection and identification of Legionella spp. strains isolated from cultures

The Legionnaires’ disease is a major issue in the healthcare because it ranks among the emerging infectious diseases in our country, particularly those caused by Legionella pneumophila serogroup 1. The severity of the infection is related to several factors including the virulence of the bacterium and the immune status of patient. Since the clinical diagnosis of Legionella infections or pneumonia with different etiology is extremely difficult, the use of new diagnostic techniques in rapid identification plays a key role. The aim of our study was to evaluate the performance of a new immunochromatographic assay can detect and identify strains of Legionella spp. from the cultures

Mycobacterium bovis BCG: the importance of an accurate identification in the diagnostic routine

M. bovis BCG is used clinically in the immunotherapy treatment of superficial bladder cancer to prevent progression to invasive disease, leading in some cases to a severe localized inflammation or disseminated infections. For this reason, an accurate and early identification of this particular microorganism is clinically relevant.We describe a case-report of bladder cancer with a urine culture-positive for mycobacteria initially diagnosed as MTB complex infection and later identified as BCG disease by molecular methods
