Multi-Year Environmental Trends Of Shrimp Black Gill (Hyalophysa Lynni) Prevalence In Texas Gulf Coast Shrimp Populations, Jillian L. Swinford, Joel Anderson
Multi-Year Environmental Trends Of Shrimp Black Gill (Hyalophysa Lynni) Prevalence In Texas Gulf Coast Shrimp Populations, Jillian L. Swinford, Joel Anderson
Gulf and Caribbean Research
Shrimp Black Gill, caused by the apostome ciliate Hyalophysa lynni, is an emerging disease impacting penaeid shrimp populations along the southeast Atlantic Coast and the Gulf of Mexico (GOM). Changing annual environmental conditions may drive infection levels of this parasitic ciliate in these populations, which comprise one of the largest fisheries in the United States. Hyalophysa lynni is established on the Texas Gulf Coast, and prevalence of this parasite has a strong seasonal and spatial trend, likely linked with high temperature and a wide range of estuarine salinities. Texas Parks and Wildlife Department monitored shrimp black gill in 2 …
Effects Of Infection Of The Protist Parasite, Dermomycoides Sp., In Dusky Gopher Frog Tadpoles, Jaime Smith
Effects Of Infection Of The Protist Parasite, Dermomycoides Sp., In Dusky Gopher Frog Tadpoles, Jaime Smith
Master's Theses
Infections of the protist parasite, Dermomycoides sp. are thought to have caused several years of low recruitment in the dusky gopher frog (Rana sevosa) populations. I evaluated the effects of density of the infective zoospores, host developmental stage, and tadpoles' ability to acquire resistance to Dermomycoides sp. on dusky gopher frog tadpoles. Tadpoles were exposed to zoospore densities of 0, 250, 500, and 750 zoospores/µL at Gosner stage 25, and we found no significant differences among treatments in tadpole mortality. In evaluating susceptibility by development stage, I exposed R. sevosa to 50 zoospores/µL as eggs, embryos, hatchlings, and …
First Record Of A Spotted Fever Group Rickettsia Sp. And Theileria Annulata In Hyalomma Dromedarii (Acari: Ixodidae) Ticks In The United Arab Emirates, Mohammad Ali Al-Deeb, Sabir Bin Muzaffar, Yousif Ali Abu-Zeid, Mohamed Rizk Enan, Shahid Karim

Rickettsiosis and theileriosis can cause mortalities in camel populations. This study was conducted to achieve 2 objectives: (1) to detect the presence of SFG Rickettsia sp. and Theileria sp. in Hyalomma dromedarii Koch, 1844 (Acari: Ixodidae) ticks and (2) to determine their prevalence in the tick population on the sampled camel farms in Al-Ain, United Arab Emirates (UAE). Camel ticks (H. dromedarii) were collected from a total of 625 one-humped camels (Camelus dromedarius) in 22 sampling locations in Al-Ain, UAE. Tick samples were analyzed by Polymerase Chain Reaction (PCR). An SFG Rickettsia sp., which was 99% …
Differences In Race And/Or Gender In Attitudes And Beliefs Towards Obesity Among Students At The University Of Southern Mississippi, Erick Brown
Honors Theses
Overweight and obesity have been described by various experts as critical problems in populations around the world, especially in the United States. These issues are so characterized because they affect numerous facets of life in this society. Researchers in the medical community have repeatedly described the health-related risks associated with obesity rates, asserting that higher risks of debilitating or fatal disease are tied to one’s level of obesity. They also say that obesity rates of populations are related to other disease rates, and many imply or clearly state that obesity is the cause and therefore the problem to be contested. …
Influence Of Detritus Levels And Organic Pollution On Interspecific Resource Competition, Oviposition Behavior, And Larval Survival Of Two Tire-Inhabiting Mosquito Species (Diptera: Culicidae), David Wayne Allgood
Master's Theses
Mosquitoes (Diptera: Culicidae) are vectors of disease in the adult stage, but understanding the factors affecting distributions of the immature stages is important to the understanding and control of adult populations. Discarded automobile tires comprise important larval mosquito habitats. The Asian tiger mosquito (Aedes albopictus) and the southern house mosquito (Culex quinquefasciatus) are two medically important species commonly found in tires, but factors affecting their larval distributions in tires have not been studied, nor have their interspecific interactions. I investigated the effects of chemicals associated with organic pollution on oviposition preferences and larval survival of both …
