Bacteriocins of gram-positive bacteria

Article Abstract:

Studies on 30-60 antibacterial proteins produced by gram-positive pathogenic bacteria revealed bacteriocins translated as inactive prepeptides consisting of an N-terminal leader sequence and a C-terminal propeptide sequence. The leader peptide is removed after posttranslation modification, while the propeptide components undergo dehydration and ring formation to produce lanthionine and beta-methyl lanthionine or cystine. Bacteriocin from gram-positive bacteria can exhibit different antimicrobial spectrum after site-specific mutagenesis.

First insights into the evolution of Streptococcus uberis: A multilocus sequence typing scheme that enables investigation of its population biology

Article Abstract:

The multilocus sequence typing (MSLT) method through which it is possible to differentiate the isolates of Streptococcus uberis, which is the cause of intramammary infection of bovine mastitits, and to describe its population structure is developed. The shortfalls of the other molecular typing techniques have overcome with this system, which allows further investigation of the population biology of this organism and insights into its epidemiology of the disease.
