Streptococcus pneumoniae is an important human pathogen that has an absolute nutritional requirement for choline. Replacement of this amino alcohol in a synthetic medium by structural analogues, such as ethanolamine (EA cells), leads to alterations in several physiological properties including cell separation (Tomasz, 1968, Proc Natl Acad Sci USA 59:(More)
We have found two murein hydrolases (LytB and LytC) tightly bound to the cell envelope that have completely changed the domain building plan previously reported for the murein hydrolases of Streptococcus pneumoniae. The active center of LytB and LytC is located at the C-terminal, whereas the binding domain is at the N-terminal. LytC has been characterized(More)
Although Caligus rogercresseyi negatively impacts Chilean salmon farming, the metabolic effects of infection by this sea louse have never been completely characterized. Therefore, this study analyzed lactate responses in the plasma, as well as the liver/muscle lactate dehydrogenase (LDH) activity and gene expression, in Salmo salar and Oncorhynchus kisutch(More)
