Development of Streptococcus agalactiae vaccines for tilapia [PDF]

Diseases of Aquatic Organisms, 2016
Vaccination is a widely accepted and effective method to prevent most pathogenic diseases in aquaculture. Various species of tilapia, especially Nile tilapia Oreochromis niloticus, are farmed worldwide because of their high consumer demand. Recently, the tilapia-breeding industry has been hampered by outbreaks of Streptococcus agalactiae infection ...

Cut‐off value of somatic cell count and validation of differential somatic cell count by the fluoro‐optical method in subclinical mastitis milk in three sheep breeds

International Journal of Dairy Technology, Volume 78, Issue 2, April–June 2025.
For the first time, the DSCC fluor optic method was validated for sheep milk. Optimal cut‐off values of SCC and DSCC were calculated for three dairy sheep breeds. Somatic cell count (SCC) is a test used for mastitis control in ewes, but there is no consensus on the cut‐off value.

Cellodextrin Metabolism and Phosphotransferase System‐Catalyzed Uptake in Enterococcus faecalis

Molecular Microbiology, Volume 123, Issue 4, Page 378-391, April 2025.
In an infectious context, β‐glucoside metabolism is highly induced in Enterococcus faecalis. Our work demonstrates that this bacterium possesses a network of multiple PTS transporters dedicated to the transport of cellobiose and cellodextrins. The genes encoding the proteins involved in this metabolism are clustered within a single locus in the E ...
