Lack Of Delayed-Type Hypersensitivity In Striped Bass (Morone Saxatilis), Jessica Shannon Miller
Lack Of Delayed-Type Hypersensitivity In Striped Bass (Morone Saxatilis), Jessica Shannon Miller
Biological Sciences Theses & Dissertations
Mycobacteriosis is a fatal disease in fishes caused by acid-fast bacteria in the genus Mycobacterium. This disease impacts aquaculture, aquariums, and wild fishes. Unfortunately, there are currently no non-lethal diagnostic tests for mycobacterial infection in fishes. Type IV delayed type hypersensitivity (DTH) responses in vivo and in vitro are currently used for the non-lethal detection of mycobacterial infections in humans and in animals; however, there is little information available on DTH responses in fishes. In this work, we examine in vivo DTH response in Striped Bass (Morone saxatilis), an important U.S. Eastern seaboard fish species, experimentally …
The Ecological Ramifications Of Disease And Density In The Caribbean Spiny Lobster, Panulirus Argus, Donald C. Behringer Jr.
The Ecological Ramifications Of Disease And Density In The Caribbean Spiny Lobster, Panulirus Argus, Donald C. Behringer Jr.
Biological Sciences Theses & Dissertations
In 1999, I discovered the first virus known to be pathogenic to any species of lobster. HLV-PA is a pathogenic herpes-like virus that infects juvenile Caribbean spiny lobster, Panulirus argus, in the waters off south Florida (USA), and it alters the behavior and ecology of this species in fundamental ways. Gross signs of HLV-PA infection are lethargy, morbidity, cessation of molting, and discolored, “milky” hemolymph that does not clot. HLV-PA infects the hemocytes of host lobsters, specifically the hyalinocytes and semi-granulocytes, but not the granulocytes. When hemolymph from infected donors was injected into healthy juvenile lobsters, 90% of the …
Development Of An Electrotransformation Technique For Streptococcus Iniae And Preliminary Characterization Of The Hemolysin Associated With This Bacterium, Kimberly Ann Hahn
Development Of An Electrotransformation Technique For Streptococcus Iniae And Preliminary Characterization Of The Hemolysin Associated With This Bacterium, Kimberly Ann Hahn
Biological Sciences Theses & Dissertations
Streptococcus iniae is a gram-positive organism responsible for causing disease in both freshwater as well as saltwater fish. Every year fisheries lose fish by the tons due to diseases caused by this organism. In 1991, the first reported human case of disease associated with this organism was described. Since this initial case, there have been numerous other reported cases of S. iniae infections. This organism is a catalase negative, facultatively anaerobic organism that produces a capsule and when plated onto blood agar demonstrates β-hemolytic activity.
In this study, the relationship between the hemolysin produced by S. iniae and the lactate …
