Streptococcosis in seabass (Lates calcarifer) [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2005
Streptococcus sp. isolated from infected seabass (Lates calcarifer) can grow on medium at pH 9.6 and salinity 0 ppt. The lethal dose where the mortality is 50 percent (LD50) was 1.937×103 CFU/ml after 14 days.

Development of a Serotyping Scheme for Streptococcus pasteurianus: An Underreported Zoonotic Pathogen. [PDF]

Transbound Emerg Dis
Streptococcus pasteurianus is an opportunistic and underreported zoonotic pathogen capable of causing severe infections in both humans and animals, and it is also an etiological agent of swine streptococcosis. Despite its clinical and veterinary relevance, no systematic serotyping scheme has previously been established for this species.

Identification of the RNA-binding domain-containing protein RbpA that acts as a global regulator of the pathogenicity of Streptococcus suis serotype 2

Virulence, 2022
Streptococcus suis serotype 2 (SS2), an emerging zoonotic pathogen, causes swine diseases and human cases of streptococcal toxic shock syndrome. RNA-binding proteins (RBPs) can modulate gene expression through post-transcriptional regulation.

An Auto-Regulating Type II Toxin-Antitoxin System Modulates Drug Resistance and Virulence in Streptococcus suis

Frontiers in Microbiology, 2021
Toxin-antitoxin (TA) systems are ubiquitous genetic elements that play an essential role in multidrug tolerance and virulence of bacteria. So far, little is known about the TA systems in Streptococcus suis.
