Research

Bacteriophage Genomics

My laboratory is actively sequencing the genomes of bacteriophages, with the goals of understanding virus evolution and the construction of useful vector systems. Towards this end we have sequenced a number of phages infecting Escherichia coli (T1, rv5), Pseudomonas (D3, F116, gh-1) and Salmonella (P22) species. Recently we have completed the sequence of the first bacteriophage (BCJA1c) active on an alkaliphilic bacterium. I have also contributed to the annotation of two Vibrio (VP2, VP5) and two Salmonella (ε15, ε34) phages. Coliphage T7 is one of the best studied bacteriophages and one of the first to be completely sequenced. The T7 sensu strictu group of phages is composed of phages T7, T3, φYeO3-12, φA1122 and gh-1 which are lytic phages sharing all essential genes in common. Evolution of this group of viruses most likely proceeds through the initial acquisition of host range mutations followed by genetic ìadjustmentî (known as amelioration) to the biochemical environment of the new host. I am interested in isolating and analyzing other members of this group of viruses.

Spirochete Cytochemistry

I am interested in the cytochemistry of spirochetes, in particular the structure and function of their outer membranes. Work with Spirochaeta aurantia has shown the presence of several novel glycolipids rather than lipopolysaccharide. The sequence of one of these has been recently published.
