In Vivo And In Vitro Pathogenesis Of Francisella Asiatica In Tilapia Nilotica (Oreochromis Niloticus), Esteban Soto Jan 2010

In Vivo And In Vitro Pathogenesis Of Francisella Asiatica In Tilapia Nilotica (Oreochromis Niloticus), Esteban Soto

LSU Doctoral Dissertations

Francisella asiatica is a Gram negative, facultative intracellular pathogen that causes fish francisellosis. In this project, homologues to the F. tularensis iglABCD genes were found present in F. asiatica. As few as 23 F. asiatica bacteria injected in the peritoneum were found capable of causing mortalities in tilapia nilotica (Oreochromis niloticus), and even fewer were enough to cause pathological changes. We examined the in vivo and in vitro interaction of F. asiatica wild type (WT) and a ÄiglC strain with tilapia and tilapia head kidney derived macrophages (HKDM). The ÄiglC was found to be attenuated following intraperitoneal and immersion challenges …

Phylogenetics And New Approaches To Vaccine Development For West Nile, Arun Venkatesh Iyer

West Nile virus (WNV) was first isolated in 1937 from a febrile Ugandan woman. WNV now has a worldwide distribution from Australia and India in the east to Europe and the United States in the west. The first human cases of WNV in the United States were detected in New York in 1999. The North American isolates were also found to be highly neuroinvasive and neurovirulent and in many cases leading to mortality or permanent CNS sequelae among humans. WNV was first isolated in Louisiana in 2001. The genome of this virus named LSU-AR01was sequenced and a detailed genetic analysis …
