Induction and characterization of lysogenic bacteriophages fromStreptococcus iniae

Journal of Applied Microbiology, 2013
To investigate the presence of prophage in Streptococcus iniae, a highly problematic fish pathogen.Cross-spotting assays and mitomycin C inductions were conducted to screen for prophage in 48 Strep. iniae isolates. Bacteriophages were characterized by plaque assays, transmission electron microscopy and DNA restriction enzyme digestion.

Combination effects of cephalexin and gentamicin on Edwardsiella tarda and Streptococcus iniae

International Journal of Antimicrobial Agents, 2003
The objective of this study was to determine the in vitro activity of cephalexin-gentamicin combination by a microbroth chequerboard technique against clinical isolates of Edwardsiella tarda and Streptococcus iniae. Gentamicin was shown more susceptible than cephalexin against both bacteria.

Antimicrobial activity of the biopolymer chitosan against Streptococcus iniae

Journal of Fish Diseases, 2019
AbstractThe antimicrobial activity and mode of action of chitosan were evaluated against Streptococcus iniae, a pathogenic Gram‐positive bacterium of fish worldwide. Cell proliferation kinetics were examined following exposure to varying concentrations of chitosan. The action of chitosan on S.

Identification and immunoprotective analysis of a Streptococcus iniae subunit vaccine candidate

Vaccine, 2010
Streptococcus iniae is a Gram-positive bacterium and a severe aquaculture pathogen that can infect a wide range of farmed fish species. In the summer of 2006, an epidemic broke out in a fish farm in north China, and examination of moribund fish (Japanese flounder) identified the possible etiological agent of the outbreak as a strain named SF1, which ...

Identification of some main Streptococcus iniae associated proteins: relationship

Veterinary Research Communications, 2017
The surface-associated proteins play a key role in bacterial physiology and pathogenesis, and are the major targets in the development of new vaccines. These proteins contribute to the adaptation of bacteria to different hosts and environments. To study differences at the genomic level, we first sequenced the whole genome of Streptococcus iniae from ...

Orthologues of Streptococcus pyogenes nuclease A (SpnA) and Streptococcal 5′-nucleotidase A (S5nA) found in Streptococcus iniae

The Journal of Biochemistry, 2018
Streptococcus pyogenes nuclease A (SpnA) and streptococcal 5' nucleosidase A (S5nA) are two recently described virulence factors from the human pathogen S. pyogenes. In vitro studies have shown that SpnA is a nuclease that cleaves ssDNA and dsDNA, including the DNA backbone of neutrophil extracellular traps. S5nA was shown to hydrolyse AMP and ADP, but

Environmental factors affecting the susceptibility of barramundi to Streptococcus iniae

Aquaculture, 2009
A long-term environmental study was conducted to evaluate the significance of water temperature, pH and salinity on the prevalence of Streptococcus iniae mortalities in barramundi sea-cage facilities. It was determined that there is a strong association between temperature and increased mortality, specifically between 25 and 28 °C. Temperatures outside

Invasive infections due to a fish pathogen, Streptococcus iniae. S. iniae Study Group.

The New England journal of medicine, 1997
Streptococcus iniae is a pathogen in fish, capable of causing invasive disease and outbreaks in aquaculture farms. During the winter of 1995-1996 in the greater Toronto area there was a cluster of four cases of invasive S. iniae infection in people who had recently handled fresh, whole fish from such farms.We conducted a prospective and retrospective ...
