A Comparison Of Olfactory Organ Development And Feeding Behavior In Larval Fathead Minnows, Pimephales Promelas Rafinesque, Robert Molloy
Masters Theses & Specialist Projects
The early recruitment and use of the chemoreceptive senses, olfaction and gustation, are important for early behavior development in fathead minnows and the ability of larvae to survive after hatching. Chemoreception is used in the location of food, avoidance of predators, and for intraspecific communication. Furthermore, some studies have shown the olfactory system to be adversely impacted by environmental contaminants and low pH. Since the fathead minnow is a commercially raised baitfish in the aquaculture industry, and serves as a standard test organism for bioassays and reaction studies of aquatic contamination by the United States Environmental Protection Agency, an understanding …

The Effects Of Lead Acetate On Host Susceptibility To Trypanosoma Cruzi, Tabitha Ellis
Masters Theses & Specialist Projects
Trypanosoma cruzi. a protozoan parasite, causes American trypanosomiasis or Chagas' disease. The infective stage of this parasite resides in the hindgut of the reduviid bug (family Reduviidae), which is both host and vector, and is transmitted to the mammalian host through fecal material released during a blood meal. Chagas' disease, an acute to chronic infection resulting in fever, malaise, and heart and liver enlargement, is becoming a concern in the United States due to the large increase in Latin American immigrants, and the lack of safe and effective therapeutic treatment and vaccination. Another growing concern in the United States involves …
Antibody Response To Heat Shock Proteins Of Trypanosoma Cruzi And Histopathology In Mice Infected And Maintained At Elevated Environmental Temperature, Ahmed Arif
Masters Theses & Specialist Projects
Trypanosoma cruzi is an obligate intracellular parasite infecting 18-20 million people in Latin America. It is the causative agent of Chagas' disease, commonly referred to as American Trypanosomiasis. The C3H murine model is widely used to study experimental Chagas' disease. It is well documented that when these highly susceptible mice are infected with the Brazil strain of T. cruzi and maintained at room temperature (RT), mice die between day 35-45 of infection. However, when held at an elevated temperature of 36°C, C3H mice survive an otherwise lethal infection with T. cruzi. When held at 36°C, the body temperature of the …

The Effect Of Acute Low Ph On Feeding And Locomotor Activity Of Larval Fathead Minnows, Pimephales Promelas, Sharon Ore
Masters Theses & Specialist Projects
Lowered pH conditions in aquatic environments can have a negative impact on many aquatic organisms. In fish it has been shown that acidic water conditions may result in altered gill morphology, reduced reproductive success, changes in locomotor and feeding behavior and even death. Juveniles and adults have been the primary focus of research. However, the larval stage is potentially the most sensitive to toxicity. It is also important ontogenetically as several crucial development thresholds, such as first feeding, occur during this period. The impact of acute low pH on feeding performance was investigated in larval fathead minnows one to fifteen …
