Well, the time has officially arrived! Next week, I will begin my preliminary exams to fulfill my requirements to move from a Ph.D student to a Ph.D candidate! This means that starting on Monday, I will start a week of written exams, one from each of my dissertation committee members.
Over the last 2 months or so, I have been studying every aspect of biology, ecology, immunology, and aquaculture that relates to my research.
As mentioned in the project description of my Aeromonas work, we are currently working with two different strains/genotypes of virulent Aeromonas hydrophila. Dealing with multiple strains of a bacteria can prove difficult with creating vaccines or administering antibiotics so we wanted to see how the temporal distribution of these two strains compared.
So, we analyzed the isolates from various cases using polymerase chain reaction (PCR) and electrophoresis. The image below shows what a typical electrophoresis gel looks like and how to read it.
