Three undergraduate students, majoring in Biology, participated in a pilot, five-week Food Safety Summer Scholars Program at Texas Wesleyan University during the summer of 2011. The students worked under the mentorship of Dr. Angela Roberts. Rebecca Mandujano, a senior Biology major, studied how effectively a recipe for homemade queso fresco kills Listeria monocytogenes during cheese preparation. . Truc Nguyen, a senior Biology major, used site-directed mutagenesis to probe the contribution of a premature stop codon in the flaR gene of Listeria monocytogenes on flagellar motility. Truc's poster describing his research and entitled, "Rescue of the flaR gene in strain N1-003 of Listeria monocytogenes" won first place in the microbiology category at the 2012 Beta Beta Beta National Convention in San Juan, Puerto Rico. Lorena Ortiz, a senior Biology major, used cell culture to compare the intracellular growth rates of strains of Listeria monocytogenes isolated from human clinical cases of listeriosis. |
