Haemophilus parasuis, a normal Gram-negative bacterium, may cause Glässer’s disease and pneumonia in pigs. This study aims to identify the genes related to natural competence of the serotype 11 strain SC1401, which frequently shows competence and high pathogenicity. SC1401 shows many differences from strains without natural competence within the molecular basis. We performed complete genome sequencing together with restriction modification system analysis to lay the foundation for later study. Copyright © 2016 Dai et al.
Here, we report the genome sequence for Bibersteinia trehalosi strain Y31, isolated from the lungs of a bighorn sheep (Ovis canadensis) that had succumbed to pneumonia, which exhibits proximity-dependent inhibition (PDI) of Mannheimia haemolytica The sequence will be used to understand the mechanism of PDI for these organisms.

We examined and compared both the methylomes and the modification-related gene content of four sequenced strains of Bibersteinia trehalosi isolated from the nasopharyngeal tracts of Nebraska cattle with symptoms of bovine respiratory disease complex. The methylation patterns and the encoded DNA methyltransferase (MTase) gene sets were different between each strain, with the only common pattern being that of Dam (GATC). Among the observed patterns were three novel motifs attributable to Type I restriction-modification systems. In some cases the differences in methylation patterns corresponded to the gain or loss of MTase genes, or to recombination at target recognition domains that resulted…
A genome sequence of the Mycoplasma bovis Ningxia-1 strain was tested by Pacific Biosciences (PacBio) single-molecule real-time (SMRT) sequencing technology. The strain was isolated from a lesioned calf lung in 2013 in Pengyang, Ningxia, China. The single circular chromosome of 1,033,629 bp shows differences between complete Mycoplasma bovis genome in insertion-like sequences (ISs), integrative conjugative elements (ICEs), lipoproteins (LPs), variable surface lipoproteins (VSPs), pathogenicity islands (PAIs), etc. Copyright © 2018 Sun et al.
Sheep scab, caused by infestation with Psoroptes ovis, is highly contagious, results in intense pruritus, and represents a major welfare and economic concern. Here, we report the first draft genome assembly and gene prediction of P. ovis based on PacBio de novo sequencing. The ~63.2-Mb genome encodes 12,041 protein-coding genes.

Mycobacterium bovis is the causative agent of bovine tuberculosis, an infectious disease that affects both animals and humans and thus presents a risk to public health and the livestock industry. Here, we report the genome sequences of five Mycobacterium bovis strains that represent major genotype clusters observed in farmed animals and wildlife in Canada.© Crown copyright 2018.
We report here the complete genome sequence of Campylobacter jejuni strain 12567, a member of a C. jejuni livestock-associated clade that expresses glycoconjugates associated with improved gastrointestinal tract persistence. Copyright © 2018 Sacher et al.
Avian pathogenic Escherichia coli (APEC) is the causative agent of colibacil- losis, a disease that affects poultry production worldwide and leads to multimillion-dollar losses annually. Here, we report the genome sequence of APEC O2-211, a sequence type 117 (ST117) strain isolated from a diseased chicken.
We report here the complete closed genome sequence of Moraxella bo- vis strain Epp-63 (300) (Epp63). This strain was isolated from an infectious bovine keratoconjunctivitis (IBK) case in 1963. Since then, Epp63 has been used extensively for IBK research. Consequently, the genome sequence of Epp63 should help eluci- date IBK host-pathogen interactions.
Pasteurella multocida is an animal-associated Gram-negative member of the Pasteurellaceae family. It is an opportunistic pathogen and is one of the principal bacterial species contributing to bovine respiratory disease complex (BRDC) in feedlot cattle. We present 16 closed genome sequences and antibiograms of isolates cultured from calves exhibiting clinical signs of BRDC and from control calves not showing signs of BRDC.
