LSU Doctoral Dissertations
Photobacterium damselae subspecies piscicida, previously known as Pasteurella piscicida, is an important pathogen of hybrid striped bass and many fish species cultured in brackish water in the United States, Japan, Europe, and the Mediterranean. The purpose of this study is to investigate virulence mechanisms that contribute to the pathogenesis of this organism. The ability of P. damselae to survive/replicate within hybrid striped bass macrophages was evaluated with an in vitro killing assay. Results indicated that the numbers of bacteria recovered from macrophages at 3, 6, 12, and 18 hours of incubation increased significantly over time. In contrast, the numbers of …
