Streptococcal disease and columnaris are common in tilapia aquaculture across the globe. Coinfections also but often overlooked or not reported. In present study, we describe clinical presentation of streptococcosis coinfection diseased Nile ( Oreochromis niloticus ), phenotypic (Lancefield grouping, hemolytic pattern, biochemical characteristics, antibiotic susceptibility) genotypic (multilocu...
The identification of the clinically relevant viridans streptococci group, at species level, is still problematic. The aim of this study was to extract taxonomic information from the complete genome sequences of 67 streptococci, comprising 19 species, by means of genomic analyses, multilocus sequence analysis (MLSA), average amino acid identity (AAI), genomic signatures, genome-to-genome distan...
Objectives To provide information about the genetic relationships and mechanism underlying carbapenem resistance in Pseudomonas aeruginosa clinical isolates of a hospital in China. Materials and methods One hundred and sixty P. aeruginosa strains were isolated from a hospital in China. Susceptibility to 14 antimicrobial agents was determined by antimicrobial susceptibility testing. Multilocus...
There have been many efforts to develop Bacillus anthracis detection assays, but the problem of false-positive results has often been encountered. Therefore, to validate an assay for B. anthracis detection, it is critical to examine its specificity with the most closely related Bacillus isolates that are available. To define the most closely related Bacillus isolates to B. anthracis in our Baci...
Conidia of Aspergillus species are widely distributed and ubiquitous in outdoor and hospital environments. There are high numbers of patients with weakened immune systems, therefore Aspergillus infections are increasing in hospitals. Molecular typing of Aspergillus strains obtained from patients and their environment is an important tool for epidemiological and public health studies. Fingerprin...
Nine isolates from Argyrolobium uniflorum, Lotus creticus , Medicago sativa (Tunisia) and Lotus arabicus (Senegal) were analysed by multilocus sequence analysis (MLSA) of five housekeeping genes (recA, atpD, glnA, gltA and thrC), the 16S rRNA gene and the nodulation gene nodA. Analysis of the individual and concatenated gene sequences demonstrated that the nine new strains constituted three sta...
Halobacteria require high NaCl concentrations for growth and are the dominant inhabitants of hypersaline environments above 15% NaCl. They are well-documented to be highly recombinogenic, both in frequency and in the range of exchange partners. In this study, we examine the genetic and genomic variation of cultured, naturally co-occurring environmental populations of Halobacteria. Sequence data...
