Isolation Of A Mycobacterium Virus With The Infectivity Rate Tested At Various Temperatures, Katie Wegenast

Undergraduate Theses

Isolation techniques developed by the HHMI and the SEA-PHAGES program were used to obtain a bacteriophage from a mixture of loamy clay soil. The sample was retrieved from a forest edge in central Kentucky. The isolate produced large lytic plaques on a lawn of the bacterium Mycobacterium smegmatis. The bacteriophage was purified, amplified, and analyzed using restriction digest analysis with visualization by gel electrophoresis. Restriction digest analysis suggests the virus belongs to a group known as “A”. Mycobacteriophages are placed into distinct groups based on DNA sequences comparison. The next step in the procedure will be to document with …
