Exploring Stable Isotope Analysis For The Identification Of Prior Tick Hosts, Kiprian Gernat Jun 2018

Exploring Stable Isotope Analysis For The Identification Of Prior Tick Hosts, Kiprian Gernat

Honors Theses

Lyme disease is a pervasive illness caused by the transmission of the spirochete Borrelia burgdorferi from the bite of an infected black-legged tick, Ixodes scapularis. Ticks initially obtain the spirochete by feeding on an infected animal host. Ticks feed on a broad range of hosts, but some of these hosts are more competent carriers of Lyme disease and more readily transmit B. burgdorferi to feeding ticks. Thus, knowing what host a tick has fed on could provide valuable information in studying the transmission of Lyme disease. However, studying the relationships between ticks and their hosts has proved to be …


Testing Bacterial Antibiotic Production Under Carbohydrate And Protein Starvation, Briley Baird Jan 2018

Testing Bacterial Antibiotic Production Under Carbohydrate And Protein Starvation, Briley Baird

Honors Theses

Bacteria produce antibiotics when they are under stress, including starvation stress. Bacteria were tested under carbohydrate and protein starvation against Bacillus subtilis and Escherichia coli (due to the respective Gram positivity and negativity), in order to check for antibiotic production. The bacteria being tested were isolated by past Microbiology classes and stored in a -80°C freezer in the basement of Jones Science Center at Ouachita Baptist University. These test bacteria were grown on tryptic soy agar (TSA) to produce isolated bacterial colonies. Samples of isolated test colonies were then grown under conditions of carbohydrate starvation (M9 salts agar with 0.1 …
