Use Of Calcium Hypochlorite As A Sanitizer For Seeds Used For Sprouting: Task #2; Impact: Improved Alfalfa Decontamination Technologies, Emily Damron, Carrie Klein, Melissa Leach, Jordan Mourot, Tom Murphy, Amy Seamans, Ryan Wilson

Consumption of raw or lightly cooked alfalfa sprouts has been a concern of the U.S. Food and Drug Administration (FDA) in recent years due to connections between sprouts and foodborne illnesses. Researchers have identified, contaminated seeds as the primary source of alfalfa sprouts contamination. Contamination of alfalfa seeds can originate in the field, harvesting, storing, or sprouting. Two pathogens of particular concern on alfalfa seeds are Escherichia coli 0157:H7 (E. coli) and Salmonella. These pathogens are capable of producing biofilms that provide protection for individual cells and allow for survival in otherwise hostile environments, including some disinfectant washes. Other factors …
A Survey Into The Prevalence Of Parasitic Helminths In Boiler Breeders, Anita Sarathi
A Survey Into The Prevalence Of Parasitic Helminths In Boiler Breeders, Anita Sarathi
Inquiry: The University of Arkansas Undergraduate Research Journal
A survey was conducted to determine the prevalence of helminth infections in spent broiler breeders. Intestinal tracts from 10 birds from each of five farms were obtained and examined for parasite identification and quantification. Heterakis gallinarum infections were the most common, followed in order of decreasing incidence by Capillaria obsignata, Ascaridia galli and Raillietina cesticillus. Peak worm burdens for individual birds were 121 (A. galli), 535 (H. gallinarum), 2I5 (C. obsignata) and 125 ( R. cesticillus). Significant farm-to-farm variation in worm burdens was observed.
Lymphocyte Profiles In Blood And Tumors Of Arkansas Rous Sarcoma Regressor And Progressor Chickens, Brant Ward
Lymphocyte Profiles In Blood And Tumors Of Arkansas Rous Sarcoma Regressor And Progressor Chickens, Brant Ward
Inquiry: The University of Arkansas Undergraduate Research Journal
The Arkansas Rous Sarcoma Regressor (AR) and Progressor (AP) lines of chickens represent an excellent model to study immune responses to tumors. Both lines of chickens initially develop tumors when injected with Rous sarcoma viros (RSV) or with DNA coding for the RSV oncogene v-src (v-src DNA). AR chickens will eventually regress the tumors whereas AP chickens will allow the tumors to progress to a terminal stage. By using both v-src DNA and RSV for tumor induction, we were able to compare the immune response to tumor antigens alone and tumor antigens in combination with viral components, respectively. To study …
