Mycobacterium simiae is a non-tuberculosis mycobacterium causing pulmonary infections in both immunocompetent and imunocompromized patients. We announce the draft genome sequence of M. simiae DSM 44165(T). The 5,782,968-bp long genome with 65.15% GC content (one chromosome, no plasmid) contains 5,727 open reading frames (33% with unknown function and 11 ORFs sizing more than 5000 -bp), three rR...

Mycobacterium simiae is a multidrug-resistant, slowgrowing, nontuberculous mycobacterium (NTM) that has been rarely reported as a cause of pulmonary infections and disseminated disease in immunocompromised hosts, especially in patients with advanced AIDS [1]. Nontuberculous mycobacterium infections caused by M simiae have increasingly been reported as a cause for cervical lymphadenitis in immun...

We describe here the characterization of five isolates of Mycobacterium simiae-like organisms representing a novel group based on whole-cell fatty acid analysis and genotypic evaluation. Two of the five isolates in this study, W55 and W58, were previously considered to belong to M. simiae serotype 2. Analysis of cellular fatty acids by gas-liquid chromatography indicated a close clustering of t...

Mycobacterium simiae is a non-tuberculous mycobacterium (NTM) endemic to the southwestern United States, the Middle East and Cuba, and has been isolated from tap water, including municipal water [1]. Although NTM form an integral part of the environment, they have potential to cause clinical disease in immunocompromised hosts [2–4]. M. simiae most commonly causes pulmonary disease, however, bon...

Bacteremic pneumonia caused by Mycobacterium simiae in non-human immunodeficiency virus (HIV)-infected patients has rarely been reported. We describe a non-HIV-infected adult with refractory bacteremia, osteomyelitis, and colonization of M. simiae in the respiratory tract who subsequently developed fatal bacteremic pneumonia. The isolate was confirmed as M. simiae by 16S rRNA gene analysis.

We report the draft genome sequence of Mycobacterium europaeum strain CSUR P1344, a slowly growing mycobacterium of the Mycobacterium simiae complex and opportunistic respiratory tract colonizer and pathogen. This genome of 6,152,523 bp exhibits a 68.18% G+C content, encoding 5,814 predicted proteins and 74 RNAs.

Four strains isolated in the last 15 years were revealed to be identical in their 16S rRNA gene sequences to MCRO19, the sequence of which was deposited in GenBank in 1995. In a polyphasic analysis including phenotypic and genotypic features, the five strains (including MCRO19), which had been isolated in four European countries, turned out to represent a unique taxonomic entity. They are scoto...

We report a case of lung infection due to Mycobacterium simiae in an immunocompromised patient without acquired immunodeficiency syndrome. The patient had multiple pulmonary nodules similar to those seen in cases of lung disease caused by Mycobacterium avium in elderly women. Appropriate therapy for M. simiae disease should be determined because, in some cases, the risk of adverse effects can o...

conclusion the high discriminative power of hsp65 pattern particularly hpaii digestion, provide an exact and costeffective method for rapid identification of m. simiae strains among registered pulmonary cases. results of 962 culture positive specimens, 17(1.7%) were identified as m. simiae species; majority of them were multidrug-resistance (12; 70.5%). the overall detection rate by tb11, tb12 ...
