Peripheral Blood Leukocyte Response And Macrophage Function During Eimeria Adenoeides Infection In Turkey Poults, Amanda D. Drake, Sarah E. Heuer, Timothy G. Kimball, Timothy O. Peters, H. David Chapman, Gisela F. Erf

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Intestinal coccidiosis, caused by various species of Eimeria, is an economically important disease of chickens and turkeys. The peripheral blood leukocyte response and macrophage functions during a coccidial infection in turkeys have not been defined. To examine these aspects of innate immunity during primary Eimeria infection in turkeys, 4-week-old poults were orally inoculated with either 50,000 E. adenoeides oocyst (24 infected poults) or water (24 control poults). To monitor the concentrations and proportions of white blood cells (WBC) throughout the course of infection, heparinized blood was collected from 12 infected and 12 control poults prior to inoculation (day 0), and …

Escherichia Coli O157:H7 In Free-Ranging Deer In Nebraska, David G. Renter, Jan M. Sargeant, Scott E. Hygnstrom, Jeff D. Hoffmann, Jerry R. Gillespie

School of Natural Resources: Faculty Publications

In order to determine the prevalence and distribution of the human pathogen, Escherichia coli O157:H7, in free-ranging deer, hunters were asked to collect and submit fecal samples from deer harvested during a regular firearm season (14–22 November 1998). Prior to the season, 47% of the hunters with permits in the southeastern Nebraska (USA) study area indicated a willingness to participate in the study. Approximately 25% of successful hunters in the area submitted deer fecal samples. Escherichia coli O157:H7 was cultured from four (0.25%) of 1,608 total samples submitted. All of the fecal samples that were properly identified (1,426) and all …

Bulletin 4474 - Exotic Diseases - Horses, Agriculture Western Australia

Bulletins 4000 -

An exotic disease is a disease that is not present in Australia.

If an exotic disease did occur in Australia it would cause production losses, stock deaths and stop exports of primary production. When export markets are lost they can only be re-established once it is proven the disease is eradicated.

Characterization Of A PorosTm-Fumonisin B1 Affinity Column For Isolating Ceramide Synthase From Rat Liver, S. Jernigan, W. B. Melchior Jr., G. R. Jenkins, K. L. Rowland, D. W. Roberts, P. C. Howard, H. Tolleson

Journal of the Arkansas Academy of Science

Fumonisin B1 is a mycotoxin produced by fungi of the genus Fusarium, common pathogens of corn and other grain plants. Toxic effects associated with fumonisin B1 include equine leukoencephalomacia, porcine pulmonary edema, rat renal carcinoma, and murine hepatocellular carcinoma. Increased risk for esophageal cancer in humans has been epidemiologically associated with consumption of corn contaminated with Fusarium, suggesting that fumonisin B1 may be involved. The biological effects of fumonisin B1 exposure result primarily from disruption of de novo sphingolipid biosynthesis via inhibition of ceramide synthase. Exposure of animals or cultured cells to fumonisin B1 results in the characteristic accumulation of …

Distribution Of Leconte's Free-Tailed Bat (Tadarida Brasiliensis Cynocephala) In Arkansas, With Notes On Reproduction And Natural History, David A. Saugey, D. Blake Sasse, J. D. Wilhide, Drew Reed, Tammy R. Jones, Darrell R. Heath, Daniel R. England

Journal of the Arkansas Academy of Science

During the past 20 years (1982-2001) we have studied the biology, occurrence and distribution of LeConte's (Brazilian) free-tailed bat, Tadarida brasiliensis cynocephala, in Arkansas. Colonies and individuals were reported from man made structures only. Four new county records have been documented since 1988, extending the range from the central part of the state to Arkansas's northern-most tier of counties. Numerous nuisance maternity colonies were investigated during exclusion activities and one, year-round colony provided the majority of reproductive data. A total of 152 free-tailed bats was submitted to the Arkansas Department of Health Rabies Laboratory (1982-2001); most during February through April, …
