- Here, we report the complete genome sequence of Mycobacterium immunogenum type strain CCUG 47286, a nontuberculous mycobacterium. The whole genome has 5,573,781bp and covers as many as 5,484 predicted genes. This genome contributes to the task of closing the still-existing gap of genomes of rapidly growing mycobacterial type strains.

- A putative type II toxin-antitoxin (TA) system was found in the clinical isolate Mycobacterium sp. MHSD3, a strain closely related to Mycobacterium chelonae. Further analyses of the protein sequences of the two genes revealed the presence of domains related to a TA system. BLAST analyses indicated the presence of closely related proteins in the genomes of other recently published M. chelonae strains. The functionality of both elements of the TA system was demonstrated when expressed in Escherichia coli cells, and the predicted structure of the toxin is very similar to those of well-known zeta-toxins, leading to the definition of a type II TA system similar to epsilon/zeta TA systems in strains that are closely related to M. chelonae.

- Two Legionella- like strains isolated from hot water distribution systems in 2012 have been characterized phenotypically, bio-chemically and genomically in terms of DNA relatedness. Both strains, HCPI- 6T and EUR- 108, exhibited biochemical pheno-typic profiles typical of Legionella species. Cells were Gram-negative motile rods which grew on BCYE alpha agar but not on blood agar and displayed phenotypic characteristics typical of the family Legionellaceae, including a requirement for L-cysteine and testing catalase positive. Both strains were negative for oxidase, urease, nitrate reduction and hippurate negative, and non -fermentative. The major ubiquinone was Q12 (59.4 % HCPI- 6T) and the dominant fatty acids were C16:1 omega 7c (28.4 % HCPI- 6T, 216 % EUR- 108), C16: 0 iso (222.5 % and 213 %) and C15: 0 anteiso (19.5 % and 223.5 %, respectively). The percent G+C content of genomic DNA was determined to be 39.3 mol %. The 16S rRNA gene, mip sequence and comparative genome sequence -based analyses (average nucleotide identity, ANI; digital DNA-DNA hybridization, dDDH; and phylogenomic treeing) demonstrated that the strains represent a new species of the genus Legionella. The analysis based on the 16S rRNA gene sequences showed that the sequence similarities for both strains ranged from 98.8-90.1 % to other members of the genus. The core genome- based phylogenomic tree (protein-concatemer tree based on concatenation of 418 proteins present in single copy) revealed that these two strains clearly form a separate cluster within the genus Legionella. ANI and dDDH values confirmed the distinctiveness of the strains. Based on the genomic, genotypic and phenotypic findings from a polyphasic study, the isolates are considered to represent a single novel species, for which the name Legionella maioricensis sp. nov. is proposed. The type strain is HCPI- 6T (=CCUG 75071T=CECT 30569T).

- Mycobacterium chelonae strains are ubiquitous rapidly growing mycobacteria associated with skin and soft tissue infections, cellulitis, abscesses, osteomyelitis, catheter infections, disseminated diseases, and postsurgical infections after implants with prostheses, transplants, and even hemodialysis procedures. Here, we report the complete genome sequence of M. chelonae type strain CCUG 47445. © 2016 Jaén-Luchoro et al.
