Variation In Avian Pathogenic Escherichia Coli Colonization Levels In Chickens, Melissa Monson, Michael Kaiser, Susan Lamont

Melissa Monson

Colonization levels in five tissues after avian pathogenic Escherichia coli (APEC) inoculation were investigated in chickens to generate phenotypic data for a genome wide association study (GWAS). Bacterial loads were measured in 370 birds and varied among individuals and tissues. Mean bacterial levels were significantly different between tissues (right lung > spleen > left lung and liver > blood). There were also significant correlations in bacterial load between tissues. These data suggest that colonization levels could be used as phenotypes in GWAS and could help identify markers associated with poultry resistance to APEC infections. After verification, these markers could be used for genetic …

Association Of Different Iowa Livestock Truck Wash Stations Service Levels With Enterobacteriaceae Counts, Amber Danielson, Samaneh Azarpajouh, Anna Johnson, James Dickson, Locke Karriker, Rodney Baker, Christopher Rademacher, Troy Bigelow, Kenneth Stalder

Samaneh Azarpajouh

Data from eighteen different truck washes were used to compare the association of different service levels with Enterobacteriaceae counts. Service levels were classified into three different categories; prewash (n=78), post wash with disinfectant (n=78), and post wash without disinfectant (n=12). A total of 168 drag swabs were used for collection for the purpose of this study. Prewash services were defined as trailers before they were scraped out and washed. Post wash with or without disinfectant services were defined as after the trailers were washed and disinfectant was or was not applied. Prewash trailers tended to have higher Enterobacteriaceae counts of …

Haemorheology Of The Eastern Grey Kangaroo And The Tasmanian Devil, Michael Simmonds, Oguz Baskurt, Herbert Meiselman, Michael Pyne, Michael Kakanis, Ekua Brenu, James Keane, Rhys Christy, Sonya Marshall-Gradisnik

The blood of two Australian marsupials, the eastern grey kangaroo (Macropus giganteus) and the Tasmanian devil (Sarcophilus harrisii), has been reported to have greater oxygen-carrying capacity (i.e. haemoglobin content) when compared with that of placental mammals. We investigated whether alterations of blood rheological properties are associated with the increased oxygen-carrying capacity of these marsupials. Eastern grey kangaroos (n = 6) and Tasmanian devils (n = 4) were anaesthetised for blood sampling; human blood (n = 6) was also sampled for comparison. Laboratory measurements included blood and plasma viscosity, red blood cell (RBC) deformability, RBC aggregation and the intrinsic tendency of …

A Critical Evaluation Of Serum Methylmalonic Acid And Vitamin B12 For The Assessment Of Cobalt Deficiency Of Growing Lambs In New Zealand, Tini Gruner, J Sedcole, J Furlong, A Sykes

Dr Tini M Gruner

AIM: To derive reference ranges for serum methylmalonic acid (MMA) for the diagnosis of cobalt/vitamin B12-responsiveness in lambs and critique existing serum vitamin B12 reference ranges. METHODS: Individual animal data from earlier supplementation trials, involving 225 ewes, 106 suckling lambs, 301 lambs during the suckling and post-weaning periods and 414 weaned lambs, for which weight gain to supplementation was observed, were used to derive relationships between serum vitamin B12 and MMA, and liveweight gain. RESULTS: Serum MMA concentrations were rarely elevated above the norm of <2 >μmol/L when serum vitamin B12 concentrations were >375 pmol/L, and not elevated into the range …
