Dr Richardson's Bio

Paul E. Richardson grew up in Maine and graduated from Morse High School in 1992. He graduated in 1996 with a B.S. in Biochemistry from Lebanon Valley College. After college he worked for Bayer pharmaceuticals testing drugs. After that he went to the University of Southern Maine and got a M.S. in Medical Immunology and Molecular Biology in 1999, his thesis focused on apoptotic factors in Murine Herpesvirus. For this thesis work he was awarded the outstanding graduate student for the University of Southern Maine. After his Master’s degree he went to the University of Alabama, Birmingham PhD program in Biochemistry. In 2003 he followed his mentor to Georgia Tech. In 2004 Paul finished his PhD thesis (PhD in Biochemistry from UAB) that focused on structural modeling of proteins involved in diseases. In 2004 he took an assistant professor position at Coastal Carolina University. In 2009 he was awarded the outstanding alumni researcher in Applied Medical Sciences from the University of Southern Maine. In 2010 he got promoted to associate professor of biochemistry and in 2012 he received the Harry M. Lightsey Jr. Visiting Scholar award.


Dr Richardson's Research Focus

Dr Richardson’s research is focused at looking at novel means to prevent/inhibit bacterial infections/blooms in the environment or people. Currently there are three research projects in his laboratory. The bacteriophage project is trying to isolate and identify naturally occurring bacteriophages in our community that could be used to treat bacterial skin infections. The unnatural amino acids project it trying to determine the effectiveness of d-amino acids in inhibiting bacterial infections. The environmental bacteriophage project wants to isolate and purify naturally occurring bacteriophages in our marine estuaries to study their ability to control bacterial blooms and ecological diversity.

Humanity is besieged with the constant onslaught of bacteria and viruses on a daily basis, and we are slowly falling behind in this battle. Over the past few months outbreaks of salmonella have bedeviled our food supply, hospitals are constantly plagued with Staphylococcus infections that are resistant to antibiotics, and in one national park over 10,000 people were potentially infected by hantavirus. New weapons are needed in the fight to help inhibit and prevent these infections. Our research is focused at looking at novel means to prevent/inhibit bacterial infections/blooms in our community. The bacteriophage project is trying to isolate and identify naturally occurring bacteriophages in our community that could be used to treat bacterial skin infections. The unnatural amino acids project it trying to determine the effectiveness of d-amino acids in inhibiting bacterial infections of the skin and bacteria that cause food poisoning. The environmental bacteriophage project wants to isolate and purify bacteriophages in our marine estuaries to study their ability to control bacterial blooms.


Bacteriophages
Staphylococcus aureus is a very common pathogenic bacterium in the human population. Recently some strains of Staphylococcus aureus have developed resistance to antibiotic drugs. It is imperative to human health that treatments are developed that can destroy the bacteria even after it mutates and bacteriophages are a promising approach. Bacteriophages are viruses that only infect bacteria and are specific to the particular bacteria they infect. These bacteriophages are naturally occurring in the population and are harmless to the human host they populate, often being beneficial in their ability to control microbial populations. Unlike static drugs, bacteriophages can evolve with the bacteria to constantly keep up with the mutating pathogens. The purpose of this project is to address two questions about these naturally occurring bacteriophages; does the general population contain bacteriophages that are lytic against Staphylococcus aureus and can we isolate and identify these bacteriophages based on genomic fingerprinting and polymerase chain reaction?

Unnatural Amino Acids
Unnatural Amino Acids project looks at the use of d-amino acids to suppress bacterial and viral infections. d-amino acids are very rare, as the majority of amino acids are in the left-handed configuration (l-amino acids). The d and l prefix explains the conformation of the amino acid. Chemically they are similar, but their structures are mirror images of each other (look at your hands to get an idea). For a reason that is not fully understood, nature has selected the l configuration for amino acids, and almost every amino acid is in that confirmation (similar to the fact that most people are right handed). Because the confirmation is not complementary d-amino acids are not naturally incorporated into proteins, and if they are, the protein is often non-functional. If a protein is non-functional it could lead to the destruction or inhibition of pathogen growth. This project will look at d-amino acids’ (lysine, arginine, glutamic acid, methionine, isoleucine, and leucine) ability to inhibit growth of six genera of bacteria (Escherichia, Salmonella, Streptococcus, Bacillus, Vibrio, and Staphylococcus) and three strains of viruses (T2, T4, and X174). Salmonella and Escherichia are common bacteria that cause food poisoning on fruits and meats. Streptococcus is the bacterium responsible for strep throat, common with any child in elementary school. Staphylococcus is a common bacterium found on skin that can sometimes cause dangerous skin infections known as the flesh-eating bacteria. The other two bacteria were selected because they can serve as a model organism for other pathogenic bacteria too dangerous to handle in the lab.

Environmental Bacteriophage
This project is in the beginning phases where techniques for detection are currently being investigated. The first stage is to evaluate whether the properties of seawater (salinity, pH and dissolved oxygen content) effect the sensitivity of the Polymerase Chain Reaction (PCR) used to identify bacteriophages in water samples from environmental samples (real world conditions). The effect of the different water characteristics on the sensitivity of the PCR identification of virus particles will be analyzed to determine what sensitivity levels bacteriophage can be detected in these environmental samples with respect to each water property. This will allow a detection threshold to be determined on environmental samples and further test the sensitivity of the protocols developed. Also, this study will look at the effect seawater (salinity, pH, and dissolved oxygen content) has on bacteriophage levels in an estuary. As detailed bacteriophage counting will be done during the study to help determine sensitivity, this data will be valuable in measuring bacteriophage counts. This will also be tied into weather and temperature data collected. This project is currently being funded by a grant from Hobcaw Barnoy.
