Ribotyping and RAPD profiling of a collection of 18 Streptococcus parauberis strains isolated from diseased turbot in Galicia (NW Spain) was performed in order to analyze the possible genetic variability within this bacterial fish pathogen. In addition, the value of this technique for intraspecific classification and epidemiological studies was evaluated. Ribopatterns of DNA digested with three...

Streptococcus parauberis is a coccoid, nonmotile, alpha-hemolytic, Gram-positive bacterium of the Streptococcaceae family. Streptococcus parauberis strain KCTC11980 was isolated from the kidney of a diseased olive flounder collected from an aquaculture farm on Jeju Island in 2010. The 2.12-Mb genome sequence consists of 44 large contigs in 16 scaffolds and contains 2,214 predicted protein-codin...

Ubiquitin-40S ribosomal protein S27a (RPS27A), ubiquitin-like Fubi, and (S30FAU) are ubiquitin-related proteins that involved in the regulation of immune-related functions such as cell cycle, expression, apoptosis. This study aimed to confirm molecular characteristics, gene expression analysis, antibacterial activity RPS27A S30FAU identified from starry flounder (15 flounders 128.7 ± 18.2 g). A...

Sargassum horneri (SH) is a brown macroalgal species commonly found along the coast of Japan, China, and Korea. SH possesses valuable bioactive compounds that can be developed as functional food ingredients well pharmaceutical agents for both humans animals. In this study, was tested its potential prebiotic effect. Several solvent-assisted extracts were on growth three probiotics (LAB) (Lactoba...

Streptococcus parauberis strain SK-417 was isolated from the brain of a diseased Sebastes ventricosus, collected from an aquaculture farm in April 2013 in Kagoshima Prefecture, Japan. The draft genome sequence, obtained with a 454 GS Junior sequencing system, consists of 33 large contigs of >500 bp, totaling 1,958,836 bp, and has a G+C content of 35.4%.

Streptococcus parauberis strain SP-llh was isolated from cows with mastitis in western China in 2015. The 2,522,235-bp genome sequence consists of 46 large contigs in 14 scaffolds and contains 2,620 predicted protein-coding genes, with a G+C content of 35.3%.

The antibacterial activities of the essential oil of Eucalyptus globulus (EOEG) was determined against 7 fish pathogenic bacteria (Edwardsiella tarda, Streptococcus iniae, S. parauberis, Lactococcus garviae, Vibrio harveyi, V. ichthyoenteri and Photobacterium damselae) obtained from farmed olive flounder. The inhibitory activity was evaluated by three methods: Disc diffusion method, minimum inh...

Bovine mastitis is the most important source of loss for the dairy industry. A rapid and specific test for the detection of the main pathogens of bovine mastitis is not actually available. Molecular probes reacting in PCR with bacterial DNA from bovine milk, providing direct and rapid detection of Escherichia coli, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus dysgalactiae, Str...
