(Society for Vector Ecology, 2017-06)The incidence of tick-borne disease continues to increase in humans and companion animals in the United States, yet distribution maps for several tick vectors in Oklahoma, including Dermacentor variabilis, Dermacentor ... -
Analysis of Coxiella burnetii mediated modulation of host cells during infection
Mahapatra, Saugata (2011-07)Scope and Method of Study: Scope - To determine Coxiella burnetii mediated modulation of host cell during infection. Methods for microbiological and molecular analyses include: eukaryotic and prokaryotic cell culture, ... -
Comparative study of life cycle ecology and host-parasite interactions of horsehair worms (phylum: Nematomorpha)
Anaya, Christina (2019-07)For hundreds of years, the phylum Nematomorpha, commonly known as hairworms, has been the subject of rich and colorful folklore across the world. Many of these stories originated from characteristics such as their serpent-like ... -
Consequences of variation in host species used to complete complex life cycles of helminths: An experimental study on life cycles of Halipegus species (Digenea: Hemiuridae) from North America
Stigge, Heather Ashley (2015-05)Complex life cycles, in which discrete life history stages of a parasite are transmitted sequentially between different host species, are shared by many parasites and have evolved independently in several phylogenetically ... -
County scale distribution of Amblyomma americanum (Ixodida: Ixodidae) in Oklahoma: Addressing local deficits in tick maps based on passive reporting
Barrett, Anne W.; Noden, Bruce H.; Gruntmeir, Jeff M.; Holland, Taylor; Mitcham, Jessica R.; Martin, Jaclyn E.; Johnson, Eileen M.; Little, Susan E. (Oxford University Press (OUP), 2015-03)Geographic distribution records for the lone star tick [Amblyomma americanum (L.)] in the peer-reviewed literature are incomplete for Oklahoma, preventing accurate disease risk assessments. To address this issue and document ... -
Effects of Patch Mosaic Burning on Tick Burden on Cattle, Tick Survival, and Tick Abundance
Polito, Victoria Jean (Oklahoma State University, 2012-07-01)Patch mosaic burning (PMB) is a regimen that applies spatially discrete fires with different burning intervals. Along with focal grazing of ruminants, these disturbances create a shifting mosaic of vegetation. Variation ... -
