Yeast (Saccharomyces cerevisae) β-1,3 glucans were used as adjuvant in a Vibrio damsela vaccine for turbot (Scophthalmus maximus L.). Turbot were injected with the adjuvant prior, at the same time and after the vaccine. Several immune parameters (index and rate of phagocytosis, passive haemolytic plaque numbers, and agglutinating antibody titers) were determined at different times postinoculati...
Studies of luminescence in growing cultures of Photobacterium fischeri revealed the characteristic kinetics of light emission, including a minimal phase of bacterial light output. A dialyzable substance present in the nutrient broth medium caused this transient inhibition in light production, although this substance did not affect culture growth. Experiments were carried out to determine the me...
The involvement of long chain aldehyde in bacterial luminescence was known both from its being required for light emission in the in vitro reaction with pure luciferase and from its ability to stimulate luminescence in vivo in a certain class of dark "aldehyde" mutants. We have found that the luminescence of some (but not all) of such aldehyde mutants is also stimulated by long chain aliphatic ...
The nursehound Scyliorhinus stellaris is a threatened shark species and its population in the Mediterranean Sea declining. Programs for captive breeding repopulation marine protected areas (MPA) are being carried out. Unfortunately, pathogens may hinder conservation plans this species. An impactful disease of animals, caused by bacteria Photobacterium damselae, has been detected with increased ...
Photobacterium damselae subsp. damselae (PDD) is a known pathogen of fish, humans and marine mammals. In this study, a Multilocus Sequence Typing (MLST) scheme based on six housekeeping genes (glp, gyrB, metG, pnt, pyrC, and toxR) was developed to better understand the PDD population structure and used to type 73 PDD isolates from cetaceans, mainly striped dolphins (Stenella coeruleoalba) invol...
Photobacteriosis or fish pasteurellosis is a bacterial disease affecting wild and farm fish. Its etiological agent, the gram negative bacterium Photobacterium damselae subsp. piscicida, is responsible for important economic losses in cultured fish worldwide, in particular in Mediterranean countries and Japan. Efforts have been focused on gaining a better understanding of the biology of the path...
