Streptococcus mutans glutamate binding protein (GlnH) as antigen target for a mucosal anti-caries vaccine.

Background: In recent years, several studies have demonstrated that bacterial ABC transporters present relevant antigen targets for the development of vaccines against bacteria such as Streptococcus pneumoniae and Enterococcus faecalis. In Streptococcus mutans, the glutamate transporter operon (glnH), encoding an ABC transporter, is associated with acid tolerance and represents an important virulence-associated factor for the development of dental caries.

Results: In this study, we generated a recombinant form of the S.

Functional Profile Evaluation of TCUESC01: A New Potential Probiotic Strain Isolated during Cocoa Fermentation.

The use of intestinal probiotic bacteria is very common in the food industry and has been the focus of the majority of research in this field. Yet in recent years, research on extraintestinal microorganisms has greatly increased due to their well-known potential as probiotics. Thus, we studied a strain of (TCUESC01) extracted from fermenting cocoa.
