The Mongolian Remodeling and the structure of Anoplocephalid cestode diversity
<p>Ecological disruption plays an important role in structuring diversity of flora, fauna, and their parasites. At the end of the Eocene, climatic change across Asia resulted in a faunal turnover (the Mongolian Remodeling) as rodents diversified and larger mammals declined. Throughout the …

Host-parasite interactions between the cysticercoid larvae of the cestode Microsomacanthus hopkinsi and the amphipod intermediate host Hyalella azteca
This study examined host-parasite relations between cysticercoids of Microsomacanthus hopkinsi and the amphipod intermediate host Hyalella azteca throughout the latter's life history. There was a significant positive relationship in oncosphere consumption, parasite loads, and short-term survival in …

Investigating cestode modulation of host neuronal excitability and cell-type-specific gene expression in an in vitro mouse model of neurocysticercosis
Neurocysticercosis (NCC), caused by Taenia solium larvae, is the leading helminthic brain infection in humans, with epilepsy as its most common manifestation. Interestingly, seizures are rare during early stages when viable larvae are thought to suppress host inflammation. Seizures tend to occur …

Investigating neural responses in models of neurocysticercosis
… levels of brain infections by larvae of the pig cestode Taenia solium, a condition termed neurocysticercosis. Despite the large nature of the problem, little is known about how neurocysticercosis modulates neuronal responses to result in the development of seizures. In this thesis I have used the …

Survey of the Helminth Parasites Infecting the Alabama Waterdog <em>Necturus alabamensis</em>.
… collected from north Florida. Hosts yielded the cestode <em>Proteocephalus loennbergi</em>, monogeneans from the genus <em>Sphyranura</em>, digeneans from the genus <em>Gorgoderina</em>, and what appears to be several nematode species. Nematodes, digeneans, and cestodes were abundant while …

Fish parasites as bio-indicators of heavy metals in two South African embayments
… identified in C. capensis (n=19) include a cestode (Gyrocotyle plana), two monogeneans (Callorhynchicotyle callorhynchi and Callorhinchicola multitesticulatus) and an isopod (Anilocra sp.). The cestode was the most prevalent at 68.4 % and the monogenean, C. callorhynchi was the most abundant …

Studies on the biology of Cyathocephalus truncatus (Pallas, 1781) (Cestoda : Spathebothridea) in its fish and crustacean hosts
… Beck,all fish were found to be infected with the cestode Qvathocephalus trunca. A prevalence of 2.2% was recorded for the procercoids of C.truncatus in the amphipod crustacean Gammarus pulex in the same habitat. Other helminth parasites recorded in both fish and gammarid hosts include …

The transmission ecology of Echinococcus multilocularis in a North American urban landscape
The cestode Echinococcus multilocularis is a trophically-transmitted parasite that is typically maintained in a sylvatic cycle involving wild canid definitive hosts and small mammal intermediate hosts. As etiological agent of Alveolar Echinococcosis in humans, the cestode is currently the third …

Understanding transmission and control of Cystic Echinococcosis and other taeniid infections in the Falkland Islands
… echinococcosis, caused by the larval form of the cestode parasite Echinococcus granulosus, has been identified as an important public health risk in the Falkland Islands since the early 1940s. This prompted the instigation of an intensive control scheme in the mid-1960s, comprised of regular …

Intestinal helminth infections, distributions, and associations with health parameters of spring-migrating female Lesser Scaup in the upper Midwest
… Scaup. Forty helminth taxa (20 trematodes, 14 cestodes, 4 nematodes, and 2 acanthocephalans) were identified, including one digenean (Plenosoma minimum) for the first time in Lesser Scaup and in the Midwest. Helminth species diversity and mean total helminth abundance were greatest in northern …

Studies on the epizootiology of canine cestodes particularly Taenia multiceps and ovine coenurosis
… (7.4%) hounds in 4/12 packs. The frequency of cestode infection in farm dogs and hounds was closely associated with the feeding of uncooked meat and offal and the absence of regular anthelmintic treatment. Only one (0.6%) of 166 pet dogs and one (0.26%) of 387 foxes examined harboured Taenia …

Carbon dioxide fixation and glycogenesis in the flatworm Hymenolepis diminuta
The cyclophyllidean cestode Hymenolepis diminuta has been found to incorporate C1402 into organic acids, amino acids, and glycogen upon in vivo incubation. This incorporation was sensitive to incubation conditions, more C1402 being incorporated aerobically than anaerobically, and was also …

Reproduction, Body Condition and Dietary Variation of the Lesser Siren (Siren Intermedia)
… Seventeen individuals were infected with the cestode Proteocephalus sireni. Parasitized individuals were in significantly poorer body condition than nonparasitized individuals.

Multiple species of Phoreiobothrium from the blacktip shark,
… (Müller and Henle, 1839), was found to host cestodes in the genus Phoreiobothrium. Carcharhinus limbatus inhabits the world's tropical and warm temperate waters. As yet, 34 species of cestodes representing the orders Tetraphyllidea, Cathetocephalidea, and Trypanorhyncha have been reported to …

Molecular assessment of parasite infection within socioeconomically important UK salmonid populations
… most likely through definitive bird host. A cestode species that infected 4 trout subpopulations across the system was the medically relevant Diphyllobothrium dendriticum. Using molecular species identification techniques, it was the first finding of the parasite within UK freshwater fish …

Parasite communities associated with the Cape gurnard (Chelidonichthys capensis) and the lesser gurnard (C. queketti) from South Africa
… to infect both gurnard species include the cestode Tentacularia coryphaenae, the acanthocephalan Corynosoma australe, and the copepods Lernentoma asellina and Medesicaste penetrans. A Caligus species was only recorded to infect C. capensis and the unidentified cyst was only recorded …
