A Comparative Study Of Aldehyde Oxidase From Tumorous-Head And Oregon-R-C Strains Of Drosophila Melanogaster, Richard A. Respess Jan 1977

A Comparative Study Of Aldehyde Oxidase From Tumorous-Head And Oregon-R-C Strains Of Drosophila Melanogaster, Richard A. Respess

Retrospective Theses and Dissertations

Aldehyde oxidase has been partially purified from Oregon-R-C and tuh(ASU) strains of Drosophila melanogaster using an affinity technique. The two enzymes were subjected to a partial kinetic analysis and found to be very similar to one another. This indicated the problem of elevated aldehyde oxidase activity in tuh(ASU) at key developmental stages (Kuhn and Cunningham, 1976) is due to an abnormal regulation. A comparative isozyme study through the developmental stages showed no major differences between the enzymes indirectly supporting the idea of an abnormal regulation. A comparison of tuh(ASU) with four wild-type strains indicated it may be a fourth allozyme …


Comparative Histology Of The Respiratory Tract Of Normal Peromyscus Floridanus And P. Gossypinus And Effects Of Exposure To Solid Rocket Motor Fuel Exhaust On P. Gossypinus, Terry Lee Bitner Jan 1977

Comparative Histology Of The Respiratory Tract Of Normal Peromyscus Floridanus And P. Gossypinus And Effects Of Exposure To Solid Rocket Motor Fuel Exhaust On P. Gossypinus, Terry Lee Bitner

Retrospective Theses and Dissertations

Microscopic examination of the tracheal dimensions of normal Florida mice (Peromyscus floridanus) and cotton mice (P. gossypinus) showed no significant differences between the two species, but external examination showed the tracheal length of the Florida mouse to be longer than that of the cotton mouse. Microscopic examination of the intrapulmonary apparatus (bronchioles, alveolar ducts, atria, and alveoli) of normal Florida and cotton mice showed no significant differences in measurements between the two species. Cotton mice were exposed to exhaust gases produced by the burning of solid rocket motor (SRM) fuel. Mice exposed once for a duration of 10 min demonstrated …

Some Effects Of Solid Rocket Motor Fuel Exhausts On Avian Embryos, Lindsey Elliott Deguehery Jan 1976

Some Effects Of Solid Rocket Motor Fuel Exhausts On Avian Embryos, Lindsey Elliott Deguehery

Retrospective Theses and Dissertations

Fertile White Leghorn (Gallus gallus) and Bobwhite Quail (Colinus virginianus) were subjected to 15 min exposures produced by burning solid rocket motor (SRM) fuel. Comparative mortality data were collected. Chicken eggs were further used to study the effects of exposure on water relations and blood gas parameters. Chicken embryos exposed once on day 19 or incubation demonstrated and LD50 of 204 ppm; the LD50 for quail embryos was 175 ppm. When mortality was regressed on the final exposure concentration, chicken and quail embryos exposed on days 12 and 19 showed LD50's of 127 and 86 ppm respectively, and embryos exposed …

Cyclic Patterns Of Central Florida Sooty Mold, Bobby Ray Pohlad Jan 1975

Cyclic Patterns Of Central Florida Sooty Mold, Bobby Ray Pohlad

Retrospective Theses and Dissertations

This study was conducted to record seasonal variations in the epiphyllous sooty mold colonies found on citrus leaves in two central Florida citrus groves, to determine basic patterns of fungal growth throughout the year and to determine whether these general patterns are correlated with regional climatological data. The results indicated general seasonal variations in the reproductive units of five of the fungi from the colony. In the study, correlations were seen between the two Ascomycetes, Treubiomyces pulcherrimus and Trichomerium didymopanacis. They were found fruiting most abundantly during the winter and spring. Reproductive units of two asexual sooty mold species (Podoxyphium …


Numerical Taxonomy Of Anaerobic Bacteria Isolated From Ground Water Of A Sanitary Landfill, Kenneth J. Curry Jan 1975

Numerical Taxonomy Of Anaerobic Bacteria Isolated From Ground Water Of A Sanitary Landfill, Kenneth J. Curry

Retrospective Theses and Dissertations

Section I: Facultative and obligatory anaerobic bacteria were isolated from the ground water of a sanitary landfill characterized by sandy soil and a periodically high water table. Isolates were examined for 63 characteristics and subject to numerical analysis. Eight clusters were established and correlations with conventional taxonomy were made. The Bacteriodaceae were found to be the dominant group of organisms by the methods employed. The anaerobic population was observed to decrease as the period of seasonal rainfall ended. At the same time, gram positive anaerobes were largely replaced with gram negative ones. Leaching between sampling sites (wells) made correlations between …


Immunological Studies Of The Host Parasite Relationship Of Dirofilaria Immitis In Domestic Canines, Douglas Felton Qualls Jan 1975

Immunological Studies Of The Host Parasite Relationship Of Dirofilaria Immitis In Domestic Canines, Douglas Felton Qualls

Retrospective Theses and Dissertations

Canine immunoglobulins of the IgG group were shown to be intimately associated with the cuticle of circulating non-infection Dirofilaria immitis microfilaria. The significance of these immunoglobulins in blocking a complete immune response in the definitive host is discussed. Immunodiffusion, immunoelectrophoresis and fluorescent inhibition techniques are described and their applicability to the study of host-parasite relationships are evaluated. A rapid reproducible method for the production of specifically labeled anti-D. immitis microfilaria globulins is presented.


A Serological Survey Of Greater Orlando Human, Canine, And Feline Populations For The Presence Of Antibodies To Toxoplasma Gondii, John Louis Weihe Jan 1975

A Serological Survey Of Greater Orlando Human, Canine, And Feline Populations For The Presence Of Antibodies To Toxoplasma Gondii, John Louis Weihe

Retrospective Theses and Dissertations

Toxoplasma gondii, the etiological agent of toxoplasmosis, was first discovered in Ctenodactylus gondi, an small North African rodent, by Nicolle and Manceaux in 1908. Later the same year Splendore observed the organism in a laboratory rabbit. Human infection was first reported by Janku in 1923. Since its discovery, many investigations have shown the organism to be truly unique in the protozoan world. There appears to be only one species and only one serotype. Serologic and microscopic studies reveal Toxoplasma to have a vast host range. At least one representative of virtually every mammalian species tested harbored the parasite or showed …
