Numerical Taxonomy Of Anaerobic Bacteria Isolated From Ground Water Of A Sanitary Landfill, Kenneth J. Curry
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
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.
Cyclic Patterns Of Central Florida Sooty Mold, Bobby Ray Pohlad
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 …
A Serological Survey Of Greater Orlando Human, Canine, And Feline Populations For The Presence Of Antibodies To Toxoplasma Gondii, John Louis Weihe
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 …
