Aeromonas taiwanensis was first described in 2010 on the basis of one clinical wound isolate (strain LMG 24683(T) = A2-50(T) = CECT 7403(T)) from Taiwan. We present here the genome sequence of A. taiwanensis LMG 24683(T), which carries several genes encoding virulence determinants and Ambler class C and D β-lactamases.

Streptococcus tigurinus, a novel member of the Streptococcus mitis group, was recently identified as a causative agent of invasive infections. We report the complete genome sequences of the S. tigurinus type strain AZ_3a and S. tigurinus strain 1366. The genome sequences assist in the characterization of virulence determinants of S. tigurinus.

Mucorales are an emerging group of human pathogens that are responsible for the lethal disease mucormycosis. Unfortunately, functional studies on the genetic factors behind the virulence of these organisms are hampered by their limited genetic tractability, since they are reluctant to classical genetic tools like transposable elements or gene mapping. Here, we describe an RNAi-based functional ...

Virulence evolution may have far-reaching consequences for virus epidemiology and emergence, and virologists have devoted increasing effort to understand the modulators of this process. However, still little is known on the mechanisms and determinants of virulence evolution in sterilizing viruses that, as they prevent host reproduction, may have devastating effects on host populations. Theory p...

Horizontal gene transfer is a key step in the evolution of Enterobacteriaceae. By acquiring virulence determinants of foreign origin, commensals can evolve into pathogens. In Enterobacteriaceae, horizontal transfer of these virulence determinants is largely dependent on transfer by plasmids, phages, genomic islands (GIs) and genomic modules (GMs). The High Pathogenicity Island (HPI) is a GI enc...

Diverse gram-negative bacterial cells communicate with each other by using diffusible N-acyl homoserine lactone (AHL) signal molecules to coordinate gene expression with cell population density. Accumulation of AHLs above a threshold concentration renders the population "quorate," and the appropriate target gene is activated. In pathogenic bacteria, such as Pseudomonas aeruginosa, AHL-mediated ...

We present the complete genome sequences of five nonpathogenicListeria monocytogenesserovar 4 strains: WSLC 1018 (4e), 1019 (4c), 1020 (4a), 1033 (4d), and 1047 (4d). These sequences may help to uncover genes involved in the synthesis of the serovar antigens-phenotypic determinants of virulence deemed clinically relevant.

Whole-genome analysis of Mycobacterium tuberculosis isolates collected in Russia (N = 71) from patients with tuberculous spondylitis supports a detailed characterization of pathogen strain distributions and drug resistance phenotype, plus distinguished occurrence and association of known resistance mutations. We identify known and novel genome determinants related to bacterial virulence, pathog...

Recent work has shown how comparative genomic and microarray analyses can provide insights into the transcriptional state of uropathogenic Escherichia coli (UPEC) during infection. This study will serve as an important platform from which to identify virulence determinants and the principle mechanisms of adaptation to the urinary tract.

The whole-genome assembly of a unique rice isolate from India, Magnaporthe oryzae RMg-Dl that causes blast disease in diverse cereal crops is presented. Analysis of the 34.82 Mb genome sequence will aid in better understanding the genetic determinants of host range, host jump, survival, pathogenicity, and virulence factors of M. oryzae.
