Antibiotic-Resistant Bacteria In Freshwater Crayfish, Colby Finch
Honors Theses
The presence of antibiotic-resistant bacteria is increasing in natural aquatic environments. Alongside this, organisms that live in these ecosystems are increasingly harboring antibiotic-resistant bacteria. In this study, I analyzed the capacity for the crayfish species Procambarus vioscai paynei to harbor antibiotic-resistant bacteria. Crayfish, as well as water and sediment, were sampled from a pond at the University of Mississippi Field Station. The guts of crayfish were plated on TSA agar, as well as agar containing vancomycin, erythromycin, penicillin, tetracycline, or ciprofloxacin. Following incubation, counts of bacteria were determined. Selected bacterial isolates were tested for multiple antibiotic-resistance. Bacterial isolates were also …

Discovery Of Truffles (Tuber Species) In North Mississippi Pecan Orchards, Scout Hodges
Honors Theses
This thesis describes a study conducted in the years 2019-2022, which aimed to discover a new species of truffle in the state of Mississippi. Tuber lyonii, more commonly referred to as the “pecan truffle,” is an ectomycorrhizal fungus found on the roots of pecan trees in much of the southeastern region of the United States. Though there are many truffles native to the United States, the pecan truffle is one of the few that has been found to have high culinary value. Given the plethora of pecan orchards in the state of Mississippi, I decided to search for evidence …
