Investigation of the capsule of Francisella tularensis LVS.


The major goals of this project are to purify and characterize the capsule from F. tularensis; To isolate the genes responsible

for capsule formation; To identify outer membrane proteins capable of illiciting a cellular immune response, and to develop biosensors using the above information for rapid detection of F. tularensis.

University of Maryland subcontract as part of Mid-Atlantic RCE(subcontract from NIH)

Vaccines and immunomodulatory therapies for tularemia


The major goals of this project are to conjugate the capsule of F. tularensis to various types of proteins and in the presence

of different adjuvants evaluate the capability of the conjugate to induce a cellular immune response and determine if

protection can be provided against lethal challenge in mice and primates.

Complete genome sequencing of the Bovine Pathogen Haemophilus somnus


The major goal of this project is to sequence and annotate the genome of Haemophilus somnus strain 2336.

 Molecular basis of LOS phase variation, phosphocholine expression, and sialylation in Haemophilus somnus virulence and colonization


The major goals of this project are to investigate the genetic basis of LOS phase variation and sialylation, and determine how phase variation and sialylation affects virulence and pathogenesis in animal model systems.  



1. 98-35204-6811 Inzana (PI)                                                             12/98-11/01          $180,000                     15%


The molecular basis for Actinobacillus pleuropneumoniae capsule in virulence


The major goals of this project were to determine if the type or quantity of capsular polysaccharide affected virulence in the swine pathogen Actinobacillus (Haemophilus) pleuropneumoniae.  This was done by knocking out capsule biosynthesis genes and complementing the mutation to alter the quantity of the original capsule type or cloning

      capsule genes from another serotype in order to change the type of capsule expressed.


2. 97-39210-5006 Inzana (PI)                                                             10/97-10/00          $182,000                     15%


Risk assessment of release of recombinant Actinobacillus pleuropneumoniae


The goals of this research were to determine the risk of a recombinant, attenuated strain of A. pleuropneumoniae to transfer a kanamycin resistance gene from its genome to other bacteria in the animal or for the strain to persist in the animal.
