91	Evaluation of the virulence potential of avian pathogenic Escherichia coli isolated from broiler breeders with colibacillosis in Mississippi Joseph, Jiddu 08 August 2023 (has links) (PDF) Avian pathogenic Escherichia coli (APEC) is a bacterium that is responsible for colibacillosis in birds. However, information about broiler breeder APEC isolates is limited, but the data is critical due to the transfer of this bacteria down the production pyramid to progenies resulting in high mortality. Therefore, we evaluated the phenotypic virulence characteristics of 28 isolates using embryo lethality and day-old chick challenge assays. Also, the in vitro adhesion and invasion potential of selected nine isolates were identified. Results showed more than 1/3rd of the isolates were highly virulent and the virulence increased as the number of virulence-associated genes increased. High adhesion and invasion rates were observed among the isolates. Overall, the study helped us to evaluate the virulence characteristics of APEC from broiler breeders. However, future studies based on whole genome approach would help to identify the specific targets which can be used to develop effective interventions. avian pathogenic E. coli broiler breeders vertical transmission phenotypic virulence characterization chick challenge embryo lethality assay adhesion invasion HD11 cells Animal Diseases Animal Experimentation and Research Bacteriology Pathogenic Microbiology Poultry or Avian Science

93	The Effects of State Leader Psychology on Civil War Lethality Kelley, Brandon 01 January 2014 (has links) Does a state leader's psychology influence lethality in civil wars? This thesis analyzes the aforementioned question during post-1945 civil wars. This particular subject, paying close attention to individual psychology at the state level, is gaining traction amongst scholars, though limited scholarly attention has addressed whether leader psychology is an indicator of conflict severity in terms of lethality. The psychology of the state leader in this thesis is assessed from leadership traits and operational code indices, specifically direction of strategy (I1) and interpretation of the nature of the political universe (P1). The data and cases used are pulled from datasets by Dr. James Fearon and the Correlates of War Project. The leaders' speech content is derived primarily from prepared material and analyzed using verbal content analysis via Profiler Plus. In measuring the effects of the predictors on my dependent variable, I chose the methodological approach of count data models, specifically, zero-truncated negative binomial regression. The results from the eight models I ran show that specific psychological traits, particularly a leader's I1 and P1 scores, level of distrust, and need for power, do play a significant role when determining the causes of civil war lethality.
