Legionella longbeachae serogroup 1, predominantly found in soil and composted plant material, causes the majority of cases of Legionnaires' disease (LD) in New Zealand. Here, we report the complete genome sequence of an L. longbeachae serogroup 1 (sg1) isolate derived from a patient hospitalized with LD in Christchurch, New Zealand. Copyright © 2017 Slow et al.
USA300 is a predominant community-associated methicillin-resistant Staphylococcus aureus strain causing significant morbidity and mortality. We present here the full annotated genome of a USA300 hypervirulent clinical strain, USA300-C2406, isolated from a patient with a lethal case of necrotizing pneumonia, to gain a better understanding of USA300 hypervirulence.

Legionella is a highly diverse genus of intracellular bacterial pathogens that cause Legionnaire's disease (LD), an often severe form of pneumonia. Two L. micdadei sp. clinical isolates, obtained from patients hospitalized with LD from geographically distinct areas, were sequenced using PacBio SMRT cell technology, identifying incomplete phage regions, which may impact virulence.

Mycoplasma bovis is a major bacterial pathogen that can cause respiratory disease, mastitis, and arthritis in cattle. We report here the complete and annotated genome sequence of M. bovis strain 08M, isolated from a calf lung with pneumonia in China. Copyright © 2017 Chen et al.
Carbapenem-resistant Klebsiella pneumoniae strain 1756 was isolated from a pus specimen from a Taiwanese patient. Here, the complete genome sequence of strain 1756 is presented. Copyright © 2017 Kao et al.
Here, we report the complete genome sequences of Legionella pneumophila isolates from two collocated outbreaks of Legionnaires' disease in 2005 and 2008 in Sarpsborg/Fredrikstad, Norway. One clinical and two environmental isolates were sequenced from each outbreak. The genome of all six isolates consisted of a 3.36 Mb-chromosome, while the 2005 genomes featured an additional 68 kb-episome sharing high sequence similarity with the L. pneumophila Lens plasmid. All six genomes contained multiple mobile genetic elements including novel combinations of type-IVA secretion systems. A comparative genomics study will be launched to resolve the genetic relationship between the L. pneumophila isolates. Copyright © 2016 Dybwad et al.
Pneumocystis jirovecii is a major cause of life-threatening pneumonia in immunosuppressed patients including transplant recipients and those with HIV/AIDS, yet surprisingly little is known about the biology of this fungal pathogen. Here we report near complete genome assemblies for three Pneumocystis species that infect humans, rats and mice. Pneumocystis genomes are highly compact relative to other fungi, with substantial reductions of ribosomal RNA genes, transporters, transcription factors and many metabolic pathways, but contain expansions of surface proteins, especially a unique and complex surface glycoprotein superfamily, as well as proteases and RNA processing proteins. Unexpectedly, the key fungal cell wall components…
Mycoplasma mycoides subsp. capri (Mmc) and subsp. mycoides (Mmm) are important ruminant pathogens worldwide causing diseases such as pleuropneumonia, mastitis and septicaemia. They express galactofuranose residues on their surface, but their role in pathogenesis has not yet been determined. The M.?mycoides genomes contain up to several copies of the glf gene, which encodes an enzyme catalysing the last step in the synthesis of galactofuranose. We generated a deletion of the glf gene in a strain of Mmc using genome transplantation and tandem repeat endonuclease coupled cleavage (TREC) with yeast as an intermediary host for the genome editing. As expected, the…
Acinetobacter baumannii is an emerging nosocomial pathogen causing infections worldwide. In this study, we determined the genome sequences of two multidrug-resistant A. baumannii clinical strains isolated from a hospital in southern India. Genome analyses indicate that both the strains harbor numerous horizontally transferred genetic elements and antibiotic resistance cassettes. Copyright © 2015 Balaji et al.
Among the Enterobacteriacea Klebsiella pneumoniae is for the most part obtained from clinical samples and most probable cause of a typical form of primary pneumonia. It can also responsible for a variety of extrapulmonary infections, counting enteritis and meningitis in infants, urinary tract infections in children and adults and septicaemia in all age groups. Like wise these pathogens are significant cause of hospital acquired infections right through the world. The remarkable increase in the prevalence of antibiotic resistance in bacteria noticed in recent years represents a considerable challenge to public health microbiology worldwide. Klebsiellae have a tendency to possess antibiotic…
Here we report the genome sequencess of four Corynebacterium pseudotuberculosis strains. These include a strain isolated from a patient with C. pseudotuberculosis pneumonia (48252), a strain isolated from pus in goat (Ft_2193/67), a laboratory strain originating from strain Ft_2193/67 (CS_10), and the draft genome of an equine reference strain, CCUG 27541.
