Streptococcus parauberis is a pathogen of cattle and fish, closely related Streptococcus uberis and Streptococcus iniae We report the genomes of seven S. parauberis strains recovered from striped bass (Morone saxatilis) in the Chesapeake Bay. The availability of these genomes will allow comparative genomic analysis of Chesapeake Bay S. parauberis strains versus S. parauberis cultured from other...

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...

Streptococcus uberis and Streptococcus parauberis reference strains and isolates obtained from routine diagnostics were investigated by PCR with oligonucleotide primers designed according to species-specific parts of the 16S rRNA gene, the 23S rRNA gene, and the 16S-23S rRNA intergenic spacer region of both species. All three primer pairs allowed an identification of 67 isolates as S. uberis an...

A multiplex PCR-based method was designed for the simultaneous detection of the main pathogens involved in warm-water streptococcosis in fish (Streptococcus iniae, Streptococcus difficilis, Streptococcus parauberis, and Lactococcus garvieae). Each of the four pairs of oligonucleotide primers exclusively amplified the targeted gene of the specific microorganism. The sensitivity of the multiplex ...

background and objective: streptococcosis/lactococcosis is the cause of high morbidity and mortality in aquaculture sector and to date a number of species of streptococcus and lactococcus genera including s. iniae, s. agalactiae, s. dysagalactiae, s. parauberis, s. feacalis, l. garvieae and l. lactis have been discriminated as the cause of disease in aquatic animals. despite the use of diagnost...

AIMS To screen for the existence and determine the structure of Tn916-like element in Streptococcus parauberis serotype II strains isolated from cultured Japanese flounder in western Japan. METHODS AND RESULTS In this study, the structure of Tn916-like element and the flanking regions were characterized by polymerase chain reaction (PCR) and inverse PCR, followed by cloning and sequencing. Th...

this study was conducted to detect the common bacteria implicated in bovine mastitis in bulk tank milk by polymerase chain reaction (pcr). forty-four milk samples from bulk tank milk were obtained and submitted to our laboratory. to detect staphylococcus aureus, streptococcus agalactiae, streptococcus dysgalactiae, escherichia coli, streptococcus uberis, and streptococcus parauberis, two sets o...

Streptococcus sp. is gram-positive coccus that causes streptococcal infections in fish due to intensification of aquaculture and caused significant economic losses in fish farm industry. A streptococcal infection occurred from cultured diseased olive flounder (Paralichthys olivaceus) in May, 2005 at a fish farm in Jeju Island, Korea. The diseased flounder exhibited bilateral exophthalmic eyes a...

A multiplex PCR protocol was established to simultaneously detect major bacterial pathogens in olive flounder (Paralichthys olivaceus) including Edwardsiella (E.) tarda, Streptococcus (S.) parauberis, and S. iniae. The PCR assay was able to detect 0.01 ng of E. tarda, 0.1 ng of S. parauberis, and 1 ng of S. iniae genomic DNA. Furthermore, this technique was found to have high specificity when t...
