Trophic Ecology And Parasitism Of A Mesopelagic Fish Assemblage, Matthew Woodstock May 2018

Trophic Ecology And Parasitism Of A Mesopelagic Fish Assemblage, Matthew Woodstock

HCNSO Student Theses and Dissertations

Mesopelagic (open ocean, 200-1000 m depth) fishes are important consumers of zooplankton and are prey of oceanic predators. Some mesopelagic fishes (e.g., myctophids and stomiids) undertake a diel vertical migration where they ascend to the near-surface waters during the night to feed and descend into the depths during the day to avoid predators. Other mesopelagic fishes (e.g., Sternoptyx spp.) do not vertically migrate and remain at deep depths throughout the day. While in the epipelagic zone (surface – 200 m depth), vertically migrating fishes become prey to upper-trophic level predators, such as: tunas and billfishes. Benthic fishes (e.g ...


Vector Competence Of Aedes Sierrensis And Culex Pipiens Complex (Diptera: Culicidae) For Dirofilaria Immitis (Spirurida: Onchocercidae) In Northern California, Jeffrey Allan Kurosaka Jan 2017

Vector Competence Of Aedes Sierrensis And Culex Pipiens Complex (Diptera: Culicidae) For Dirofilaria Immitis (Spirurida: Onchocercidae) In Northern California, Jeffrey Allan Kurosaka

University of the Pacific Theses and Dissertations

Dirofilaria immitis Leidy (dog heartworm) is a life-threatening parasite transmitted by mosquitoes to domestic dogs. Endemic in the eastern United States, cases have become more prevalent over the last few decades. While prevalence in California is generally low, Lake and San Joaquin Counties have reported rates comparable to the East Coast at 3.73% and 0.71%(CAPC 2017), respectively. Aedes sierrensis is thought to be responsible for transmission in California, but in some cases, it exists in inadequate quantities and temporal ranges to explain parasite activity. Based on Huang et al. (2013) and Tran (2016), bloodfeeding patterns, and other ...

Coccidia Of Gerbils From Mongolia, Ethan T. Jensen Aug 2013

Coccidia Of Gerbils From Mongolia, Ethan T. Jensen

Dissertations and Theses in Biological Sciences

In this study, gerbils collected in the Mongolia over the summers of 2009-2012 were examined for coccidia. In total, 171 gerbils of three species from 22 localities were examined for coccidia. Coccidian oocysts were identified from 21 gerbils, but those found in 1 of those gerbils were probably pseudoparasites of the host from which they were recovered. From the remaining 20 gerbils, 7 morphotypes of Eimeria and 1 morphotype of Isospora were identified. Four of the 7 morphotypes of Eimeria were attributed to new species which were described in this study. In addition, 10 previously described species of Eimeria were ...

Ultrastructural Studies Of Two Coelozoic Myxozoans , Tom Alvin Bailey Jan 1988

Ultrastructural Studies Of Two Coelozoic Myxozoans , Tom Alvin Bailey

Retrospective Theses and Dissertations

Two species of coelozoic myxozoans were examined using scanning and transmission electron microscopy. The ultrastructure of sporogenesis of Chloromyxum trijugum and pathology associated with Chloromyxum trijugum infections of gallbaldder tissue in bluegill (Lepomis macrochirus), white crappie (Pomoxis annularis), black crappie (Pomoxis nigromaculatus), and pumpkinseed (Lepomis gibbosus) were described. The ultrastructure of the myxosporean species, Myxobilatus noturi, was also described from the urinary bladder of tadpole madtom (Noturus gyrinus). Fish samples were collected from artificial impoundments in Story County, Iowa, small streams in Northern Iowa, or from Pool 7 of the Upper Mississippi River (Wisconsin);The events of sporogenesis in C ...


Host-Parasite Interactions Of Trichomonas Gallinae (Rivolta, 1878) , Glenn Ernest Kietzmann Jr. Jan 1988

Host-Parasite Interactions Of Trichomonas Gallinae (Rivolta, 1878) , Glenn Ernest Kietzmann Jr.

Retrospective Theses and Dissertations

Ring doves (Streptopelia risoria) were orally infected with virulent palatotropic Trichomonas gallinae to address problems concerning caseous nodule (canker) formation and progression with light, scanning and transmission electron microscopy. Trichomonads initially attacked microvilli-like apical processes of palatal squamous cells as well as epithelial cell borders. Epithelial damage was associated with the phagocytosis of apical processes whereas mechanical removal of damaged and loosened cells by trichomonads was evident and pathological desquamation was pronounced. Trichomonads were invasive although they did not appear to traverse the basement membrane. The concomitant inflammatory response involved granulocytes and macrophages and the infiltration of these cells through ...


Isolation, In Vitro Excystation, And In Vitro Development Of Cryptosporidium Sp From Calves , Douglas Byron Woodmansee Jan 1986

Isolation, In Vitro Excystation, And In Vitro Development Of Cryptosporidium Sp From Calves , Douglas Byron Woodmansee

Retrospective Theses and Dissertations

Human rectal tumor (HRT) and human embryonic lung (HEL) cell lines were inoculated with oocysts and sporozoites of Cryptosporidium sp. from calves. Development of the parasites through the mature merozoite stage was observed in HRT cells and development of gametes was observed in HEL cells. The parasites were seen with both light and electron microscopy. The parasites failed to establish persistent or productive infections of the cultured cells;Use of in vitro excystation techniques to assess sporulation of oocysts revealed no evidence that sporulation occurred if oocysts were subjected to in vitro sporulation procedures. The data show that it is ...


Life Cycle And Host-Parasite Relationships Of Khawia Iowensis Calentine And Ulmer, 1961 (Cestoidea: Caryophyllidea) , Daniel Robert Sutherland Jan 1981

Life Cycle And Host-Parasite Relationships Of Khawia Iowensis Calentine And Ulmer, 1961 (Cestoidea: Caryophyllidea) , Daniel Robert Sutherland

Retrospective Theses and Dissertations

Gravid Khawia iowensis occur within the intestinal tract of the cyprinid fish (Cyprinus carpio). Proceroids occur within the coelom of the tubificid oligochaete (Aulodrilus pigueti). Naturally infected annelids were not found; in Iowa, fish infections are strictly seasonal with maximal prevalences and mean intensities occurring during August;Dero digitata, Stylaria lacustris, Ilyodrilus templetoni, Branchiura sowerbyi, Limnodrilus hoffmeisteri and A. pigueti were exposed to embryonated eggs of K. iowensis. Infections, acquired by egg ingestion, occurred only in A. pigueti. After hatching in the tubificid, oncospheres penetrate the gut wall and migrate anteriad within the host's coelom where procercoid development occurs ...

A List Of Cestode Parasites From California Mammals, Marietta Voge Oct 1955

A List Of Cestode Parasites From California Mammals, Marietta Voge

Faculty Publications from the Harold W. Manter Laboratory of Parasitology

This report brings together information on the occurrence and distribution of cestode parasites in California mammals. The original information reported herein, was obtained by students, myself, and other staff members of this university. Although the host-parasite list which follows is far from complete, the dearth of knowledge about the helminth fauna in California seems to justify the publication of relatively few data, in the hope that other workers will be able to use this list as a starting point and add to it.

With few exceptions, the common names of the hosts, as given in the host list, were obtained ...
