Isoflupredone Acetate As Ancillary Therapy For Bovine Respiratory Disease In High-Risk Stocker Calves, Claire Crews, Jeremy Powell, Elizabeth Kegley, Jana Reynolds, Pete Hornsby
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Bovine respiratory disease (BRD) is the most prevalent and devastating disease in U.S. feedlot cattle. This study evaluated the use of isoflupredone acetate in the treatment of BRD. Crossbred male beef calves (n = 192; body weight = 221 ± 3.9 kg) were acquired in two blocks from regional auction markets and transported to the University of Arkansas Stocker and Receiving Cattle Unit. Calves were observed daily for signs of respiratory illness. Antibiotic treatment was administered if calves displayed signs of respiratory illness and rectal temperature was ≥40 °C. Calves (n = 72) requiring antibiotic treatment were assigned randomly to …

Bovine cytochrome P450 3A28 is responsible for metabolizing ergot alkaloids that cattle ingest when feeding on endophyte-infested tall fescue grass. The objective of this research was to determine associations among genotype, transportation, and stress responses. Angus crossbred steers (n = 47) were genotyped (CC, CG, or GG) for a single-nucleotide polymorphism (C994G) in cytochrome P450 3A28. Genotypes were determined by polymerase chain reaction (PCR) amplification followed by restriction enzyme (Alu1) digestion. Steers were backgrounded on a mixedcultivar tall fescue pasture. Following the stocker phase, steers were transported to the feedlot for finishing. Stress responses were determined 27 h prior to, …
Safety Of Improved Milbond-Tx Mycotoxin Binder When Fed To Broiler Breeders Above Recommended Levels, Michael Schlumbohm, Judy England, Rueben Kriseldi, C. Coon
Safety Of Improved Milbond-Tx Mycotoxin Binder When Fed To Broiler Breeders Above Recommended Levels, Michael Schlumbohm, Judy England, Rueben Kriseldi, C. Coon

An increasing concern in poultry nutrition is the effects of mycotoxins in contaminated grain. Several new products have come onto the market that chemically bind these toxins preventing mycotoxicosis. However, many of these products have not been tested for safety if accidently overfed to broiler breeders. In order to simulate a feed mixing error at a feed mill, Improved Milbond-TX® was overfed to broiler breeders to see if this would cause any negative effects on bird performance. A typical corn-soybean based diet supplemented with Milbond-TX mycotoxin binder at three different levels of inclusion (0%, 0.5%, and 1%) was fed to …

Comparative Study Of Helminth Parasites Of The Many-Ribbed Salamander, Eurycea Multiplicata And Oklahoma Salamander, Eurycea Tynerensis (Caudata: Plethodontidae), From Arkansas And Oklahoma, A, C. T. Mcallister, M. B. Connior, C. R. Bursey, H. W. Robison

Journal of the Arkansas Academy of Science
Ninety many-ribbed salamanders, Eurycea multiplicata and 135 Oklahoma salamanders, Eurycea tynerensis were collected between April 2010 and April 2014 from 14 counties of Arkansas and McCurtain County, Oklahoma (E. multiplicata only) and examined for helminth parasites. Twelve (13%) E. multiplicata were infected, including two (2%) each with Brachycoelium salamandrae, Bothriocephalus rarus, Batracholandros magnavulvaris, Cosmocercoides variabilis, and Omeia papillocauda, and one (1%) each with an oligacanthorhynchid cystacanth and Fessisentis vancleavei. Forty-one (30%) of the E. tynerensis were infected, including seven (5%) with Gorgoderina tenua, two (1%) each with Phyllodistomum solidum and cyclophyllidean tapeworm cysticerci, one (0.7%) with Cylindrotaenia americana, six (3%) …

Journal of the Arkansas Academy of Science
Between June 2012 and January 2014, 147 fishes (10 species) within five families were collected from watersheds in 8 counties of Arkansas and examined for helminth parasites. Almost every fish species examined harbored at least one or more helminth parasite, including 5 trematodes (Alloglossidium sp., Plagioporus sp., Crepidostomum sp., Clinostomum marginatum and unknown metacercaria), 2 cestodes (unknown cyclophyllidean cysticerci and Corallotaenia parva), 3 nematodes (Spiroxys sp., Capillaria catostomi, and Eustrongylides sp.), and 3 acanthocephalans (unknown cystacanths, Neoechinorhynchus sp., and Leptorhynchoides sp.). We document 16 new host and 2 new distributional records for these helminths. In addition, this is the first …

Effect Of The Clostridium Difficile Tcde Protein On Membranes Of Escherichia Coli, Sophie Hollenberg
Effect Of The Clostridium Difficile Tcde Protein On Membranes Of Escherichia Coli, Sophie Hollenberg
Inquiry: The University of Arkansas Undergraduate Research Journal
Clostridium difficile infects millions of hospitalized patients worldwide, causing pseudomembranous colitis, a disease with symptoms attributable to two toxins produced by the bacterium.The PaLoc gene locus in the C. difficile genome is responsible for toxin production and activation, but it is not known how the toxins are released from the pathogen. Within PaLoc is a gene for the TcdE protein, which shares striking similarity to a class of membrane pore-forming proteins called holins. To assess whether TcdE catalyzes toxin release, the engineered tcdE gene was expressed in Escherichia coli. An arabinose promoter upstream of the tcdE gene was manipulated to …
