Genetics Of The Pig Tapeworm In Madagascar Reveal A History Of Human Dispersal And Colonization, Tetsuya Yanagida, Jean-François Carod, Yasuhito Sako, Minoru Nakao, Eric P. Hoberg, Akira Ito

An intricate history of human dispersal and geographic colonization has strongly affected the distribution of human pathogens. The pig tapeworm Taenia solium occurs throughout the world as the causative agent of cysticercosis, one of the most serious neglected tropical diseases. Discrete genetic lineages of T. solium in Asia and Africa/Latin America are geographically disjunct; only in Madagascar are they sympatric. Linguistic, archaeological and genetic evidence has indicated that the people in Madagascar have mixed ancestry from Island Southeast Asia and East Africa. Hence, anthropogenic introduction of the tapeworm from Southeast Asia and Africa had been postulated. This study shows that …


Varestrongylus Eleguneniensis Sp. N. (Nematoda: Protostrongylidae): A Widespread, Multi-Host Lungworm Of Wild North American Ungulates, With An Emended Diagnosis For The Genus And Explorations Of Biogeography, Guilherme G. Verocai, Susan J. Kutz, Manon Simard, Eric P. Hoberg Jan 2014

Varestrongylus Eleguneniensis Sp. N. (Nematoda: Protostrongylidae): A Widespread, Multi-Host Lungworm Of Wild North American Ungulates, With An Emended Diagnosis For The Genus And Explorations Of Biogeography, Guilherme G. Verocai, Susan J. Kutz, Manon Simard, Eric P. Hoberg

Background: A putative new species of Varestrongylus has been recently recognized in wild North American ungulates based on the ITS-2 sequences of larvae isolated from feces during a wide geographic survey. No taxonomic description was provided, as adult specimens were not examined. Methods: Lungworm specimens were collected in the terminal bronchioles of muskoxen from Quebec, and a woodland caribou from central Alberta, Canada. The L3 stage was recovered from experimentally infected slugs (Deroceras spp.). Description of specimens was based on comparative morphology and integrated approaches. Molecular identity was determined by PCR and sequencing of the ITS-2 region of …


Air Sac Nematode Monopetalonema Alcedinis In A Belted Kingfisher (Megaceryle Alcyon) In Maryland, Usa, Ellen Bronson, Kathleen Kelly, Eric P. Hoberg Jan 2014

Sporadic and geographically widespread reports of parasites affecting the Belted Kingfisher (Megaceryle alcyon) have been published but few have described details of the pathology. A female, adult kingfisher was found dead in a heavily wooded area of a zoo in Maryland, USA. At necropsy, numerous sexually dimorphic, 4.4–40.5-cm adult Monopetalonema alcedinis nematodes were found tightly wound within the coelomic cavity between organs and completely filling the caudal thoracic and abdominal air sacs. Abundant, 30–60-mm diameter, larvated, thick-walled ova were found in the bronchi and parabronchi, within the mesentery, and in the serosa of multiple coelomic organs. Monopetalonema alcedinis …

Parasites are agents of disease in humans, livestock, crops, and wildlife and are powerful representations of the ecological and historical context of the diseases they cause. Recognizing a nexus of professional opportunities and global public need, we gathered at the Cedar Point Biological Station of the University of Nebraska in September 2012 to formulate a cooperative and broad platform for providing essential information about the evolution, ecology, and epidemiology of parasites across host groups, parasite groups, geographical regions, and ecosystem types. A general protocol, documentation–assessment–monitoring–action (DAMA), suggests an integrated proposal to build a proactive capacity to understand, anticipate, and respond …
